Not every property transaction involves a bank. In many South African property deals, the financing comes from a private individual, a family member, a trust, or a commercial entity that is not a registered financial institution. When this happens, the lender needs security — and that security takes the form of a private bond registered over the immovable property at the Deeds Office.
Private bonds are far more common than most people realise. They underpin seller-financed property sales (the historic kustingsbrief), family property transfers where parents help children onto the property ladder, trust lending arrangements, and commercial private lending between businesses. Yet despite their prevalence, private bonds are poorly understood — and the legal pitfalls are significant, particularly around National Credit Act compliance and interest rate regulations.
This guide provides a comprehensive, legally precise explanation of private bonds in South Africa. Whether you are a seller financing a property sale, a parent lending to a child, a trust structuring a loan, or a commercial lender requiring security over immovable property, this is the definitive resource on private bonds — covering registration, costs, legislation, and the critical compliance requirements that many participants overlook.
What is a Private Bond?
A private bond — more formally called a private mortgage bond — is a mortgage bond registered over immovable property (land and buildings) where the bondholder (the lender) is a private person, trust, company, or entity, rather than a bank or registered financial institution. In every other respect, a private bond functions identically to a bank mortgage bond: it is registered at the Deeds Office, it creates a real right of security over the property, and it gives the bondholder secured creditor status.
The legal foundation for private bonds is the Deeds Registries Act 47 of 1937, which governs the registration of all bonds over immovable property in South Africa. The Act makes no distinction between bank-held bonds and privately-held bonds — both follow the same registration process, both must be prepared and registered by a conveyancer, and both create identical real rights once registered.
What makes private bonds different is not the legal instrument itself, but the commercial and regulatory context. Bank mortgage bonds are subject to the Banks Act 94 of 1990, extensive regulatory oversight, standardised lending criteria, and institutional risk management frameworks. Private bonds operate outside this institutional framework, which creates both flexibility and risk — flexibility because the parties can negotiate terms freely, and risk because the lender may not appreciate the regulatory obligations that apply, particularly under the National Credit Act 34 of 2005.
Key Characteristics of a Private Bond
- Security over immovable property: Covers land and buildings — as distinct from movable property (vehicles, equipment) which is covered by notarial bonds
- Private lender: The bondholder is a private individual, family member, trust, close corporation, or company — not a bank or registered financial institution
- Real right of security: Once registered, the bond creates a real right that is enforceable against anyone — not just the borrower. The bondholder has secured creditor status in insolvency
- Registered by a conveyancer: Only a legal practitioner admitted as a conveyancer may prepare and lodge the bond at the Deeds Office — an ordinary attorney cannot do so
- Governed by the Deeds Registries Act: The Deeds Registries Act 47 of 1937 is the primary statute, with the National Credit Act 34 of 2005 applying to the underlying credit agreement
In Plain Terms
A private bond is simply a mortgage bond where the lender is not a bank. If a parent lends a child R1 million to buy a house, a seller allows a buyer to pay in instalments, or a trust provides a loan secured against property — the lender can register a private bond over the property to protect their investment. The bond is registered at the Deeds Office just like a bank bond, and if the borrower stops paying, the lender can apply to court to have the property sold. It provides exactly the same legal protection as a bank mortgage bond.
Types of Private Bonds
Private bonds take several forms depending on the commercial context. While the legal instrument is the same — a mortgage bond registered over immovable property — the circumstances under which they arise, the parties involved, and the regulatory implications differ significantly. Understanding these distinctions is essential for structuring the transaction correctly.
Kustingsbrief (Seller's Bond)
The kustingsbrief is the oldest and most well-known form of private bond in South African law. Derived from Roman-Dutch law, it arises when the seller of immovable property agrees to finance the purchaser by allowing the purchase price (or a portion of it) to remain outstanding after transfer. The seller registers a mortgage bond over the transferred property to secure the unpaid balance. It is also called a "seller's bond" or "vendor's mortgage".
In a kustingsbrief transaction, the property transfers to the purchaser's name, but the seller simultaneously registers a bond over it. The purchaser becomes the owner of the property but cannot sell or further bond it without the seller's consent (or settling the debt). This structure was historically the primary method of financing property in South Africa before banks dominated the mortgage market.
Practical example: A farmer sells agricultural land for R5 million. The buyer pays R2 million upfront and the seller agrees to finance the remaining R3 million over 10 years at an agreed interest rate. The conveyancer transfers the property to the buyer and simultaneously registers a private bond of R3 million in favour of the seller.
Private Mortgage Bond (Third-Party Lending)
A private mortgage bond is registered when a third party (someone other than the seller) lends money to a borrower and takes security over the borrower's immovable property. Unlike a kustingsbrief, the lender has no connection to the original sale — they are simply an investor, private financier, or commercial entity providing a loan secured against property.
This type of private bond is increasingly common in South Africa as alternative lending grows. Property investors, high-net-worth individuals, and private credit funds use private mortgage bonds to structure secured lending outside the banking system. The bond may secure a new loan against existing property, or it may be registered simultaneously with a property transfer where the private lender provides the purchase finance.
Family and Trust Loans
One of the most common scenarios for private bonds is intra-family lending. Parents lend children money to purchase property, a family trust provides finance to a beneficiary, or siblings pool resources to assist one family member with a property acquisition. Registering a private bond in these situations protects the lender's investment and creates a formal, legally enforceable structure around what might otherwise be an informal arrangement.
Family and trust loans secured by private bonds also serve important estate planning and tax purposes. A loan from a trust to a beneficiary, properly documented and secured by a private bond, is treated differently from a donation for tax purposes — potentially avoiding donations tax, estate duty implications, and the section 7C deemed donation provisions of the Income Tax Act.
Important: Even between family members, a private bond should be accompanied by a written loan agreement specifying the amount, interest rate (if applicable), repayment terms, and default provisions. Without these, the arrangement may be recharacterised as a donation by SARS, or the bond may be unenforceable.
Seller-Financed Bonds (Instalment Sales)
Beyond the traditional kustingsbrief, seller financing can take various forms. In some transactions, the seller retains ownership until full payment (governed by the Alienation of Land Act 68 of 1981), while in others the property transfers and a private bond secures the balance. The choice between these structures depends on the parties' preferences, the deal size, and the tax implications.
Seller-financed bonds are particularly prevalent in agricultural property transactions, where the large purchase prices and specialised nature of farming operations mean that traditional bank finance may not be available or suitable. They are also common in commercial property sales where the seller is willing to accept deferred payment to achieve a better sale price.
Private Bonds vs Notarial Bonds
It is important not to confuse private bonds with notarial bonds. A private bond is a mortgage bond registered over immovable property (land and buildings). A notarial bond is registered over movable property (vehicles, equipment, stock). They are governed by different legislation, prepared by different practitioners (conveyancers vs notaries), and serve different commercial purposes. In some transactions, a lender may require both — a private bond over the property and a notarial bond over the movable assets.
When You Need a Private Bond
Private bonds are not niche instruments — they arise in a wide range of property transactions where bank financing is unavailable, unsuitable, or simply not the preferred option. These are the four most common scenarios where a private bond is the right solution.
Seller Financing
The seller agrees to finance the buyer directly, either because the buyer cannot obtain bank finance, or because the seller wants to structure the sale for tax efficiency. The seller registers a private bond over the property to secure the outstanding purchase price. This is particularly common in agricultural land sales, commercial property transactions, and situations where the buyer's profile does not meet bank lending criteria.
Example: A commercial property sells for R8 million. The buyer pays R3 million upfront and the seller finances R5 million over 7 years, secured by a private bond. The seller earns interest income and the buyer acquires the property without bank involvement.
Family Property Transfers
Parents help children purchase property by providing a loan instead of a gift. Registering a private bond protects the parents' investment, creates a formal legal structure, and may offer tax advantages over an outright donation. This is also common between siblings, extended family members, or family trusts providing loans to beneficiaries.
Example: Parents lend their daughter R1.5 million for a deposit. A private bond is registered over her new property, with an interest rate at or above the official rate to avoid section 7C deemed donation implications.
Trust Lending
Family trusts commonly lend money to beneficiaries or related parties for property purchases. A private bond secures the trust's loan, protects the trust assets (and therefore the beneficiaries), and creates the formal loan structure required for tax compliance. The trustees have a fiduciary duty to protect trust assets, making a registered bond essential — not optional.
Example: A family trust with surplus cash lends R2.5 million to a beneficiary to purchase a residential property. The conveyancer registers a private bond in favour of the trust, and the loan agreement specifies interest at the official rate.
Commercial Private Lending
Private credit funds, property investors, and high-net-worth individuals provide secured loans against immovable property as an investment strategy. The borrower may need bridging finance, development finance, or funding that banks will not provide due to the property type, borrower profile, or loan structure. A private bond provides the lender with real security.
Example: A property developer needs R10 million in bridging finance for 12 months while awaiting rezoning approval. A private lender advances the funds secured by a private bond over the development property, at an interest rate above prime.
Why Not Just Use a Bank?
Private bonds exist because bank financing is not always available, appropriate, or desirable. Banks have strict lending criteria, lengthy approval processes, and standardised terms that may not suit the transaction. Private bonds allow the parties to negotiate bespoke terms — including the interest rate, repayment schedule, balloon payments, and default remedies — creating flexibility that the banking system cannot offer. For sellers, offering financing can also be a powerful tool to achieve a higher sale price or close a deal that would otherwise fall through.
The Registration Process
Registering a private bond follows the same formal process as a bank mortgage bond — it must be prepared by a conveyancer, lodged at the Deeds Office, and pass examination before it is registered against the property's title deed. The process typically takes 8 to 12 weeks from instruction to registration, though it can be faster or slower depending on the circumstances.
Instruction and Loan Agreement
The conveyancer receives instructions from the lender and borrower. A written loan agreement is prepared (or reviewed if already in place) specifying the loan amount, interest rate, repayment terms, default provisions, and any National Credit Act disclosures. The loan agreement is the contractual foundation — the bond is merely the security instrument.
FICA Compliance and Due Diligence
The conveyancer collects FICA (Financial Intelligence Centre Act) documentation from both parties — identity documents, proof of residence, source of funds documentation, and (for entities) registration documents and resolutions. A Deeds Office search confirms the property description, current ownership, and any existing bonds or restrictions on title.
Bond Preparation
The conveyancer drafts the bond document, which identifies the parties, describes the property (by title deed and Surveyor-General description), states the amount secured, and sets out the bond conditions. If the private bond is being registered simultaneously with a transfer, the conveyancer coordinates the two transactions to ensure they are lodged together.
Signing and Attestation
The borrower (mortgagor) signs the bond document before the conveyancer. The conveyancer verifies the borrower's identity, confirms that the borrower understands the implications of the bond, and attests the document. If the borrower is a company or trust, the conveyancer confirms that the signatories have authority to bind the entity.
Rates Clearance and Compliance Certificates
If the bond is registered simultaneously with a transfer, a rates clearance certificate must be obtained from the municipality, confirming that all municipal accounts are paid up. Electrical compliance and other certificates may also be required depending on the transaction.
Lodgement at the Deeds Office
The conveyancer lodges the bond at the Deeds Office that has jurisdiction over the property. If registered simultaneously with a transfer, both the transfer and bond documents are lodged together and linked so they register on the same day.
Examination
The Deeds Office examiner checks the bond for compliance with the Deeds Registries Act — correct property description, valid parties, proper execution, and conformity with prescribed forms. If there are defects, the bond is rejected (noted) and the conveyancer must correct and re-lodge the documents.
Registration
Once the bond passes examination, it is registered against the property's title. The lender receives a registered bond document confirming their security. From this point, the bond is enforceable against the borrower and any third party — including a liquidator, subsequent purchaser, or other creditors.
Typical Timeline: 8 — 12 Weeks
The 8-to-12-week timeline reflects the practical reality of rates clearance delays, Deeds Office backlogs, and the coordination required when the bond is registered simultaneously with a property transfer. A stand-alone bond (registered against an already-transferred property) can be faster — typically 4 to 6 weeks — because there is no transfer to coordinate with.
The conveyancer cannot speed up the Deeds Office examination process, but ensuring that all documents are correct and complete before lodgement avoids costly rejections and delays.
Costs and Fees
The cost of registering a private bond is calculated on the same prescribed sliding scale used for bank mortgage bonds. This tariff is set by the Law Society of South Africa and published in the Government Gazette. A conveyancer is not permitted to charge less than the prescribed tariff, and the tariff is a sliding scale — higher bond values attract proportionally lower percentage fees.
Fee Components
The total cost of registering a private bond includes several components:
- Conveyancing fees: Calculated on the Law Society prescribed sliding scale based on the bond amount. This is the conveyancer's professional fee for preparing and registering the bond
- Deeds Office registration fee: A fixed fee payable to the Deeds Office for lodgement and registration of the bond
- Disbursements: Deeds Office searches, FICA compliance costs, electronic lodgement fees, postage, and administration
- VAT: 15% VAT on all professional fees
- Loan agreement preparation: If the conveyancer also drafts the underlying loan agreement, an additional fee applies — this is separate from the bond registration fee
Who Pays?
In most private bond transactions, the borrower pays the registration costs — mirroring the convention in bank mortgage bonds. However, the parties are free to agree otherwise. In seller-financed transactions (kustingsbriefs), the costs are sometimes shared or built into the financing terms. It is essential to clarify who bears the costs before the conveyancer is instructed.
Private Bonds vs Bank Mortgage Bonds
The most common question we receive about private bonds is how they compare to standard bank mortgage bonds. While both instruments create identical real rights over immovable property, the commercial reality, regulatory environment, and practical implications differ substantially.
| Aspect | Private Bond | Bank Mortgage Bond |
|---|---|---|
| Lender | Individual, trust, company, or private entity | Registered bank or financial institution |
| Property type | Immovable property (land and buildings) | Immovable property (land and buildings) |
| Type of right | Real right (identical protection) | Real right |
| Regulatory oversight | NCA may apply; no Banks Act regulation | Banks Act, NCA, SARB prudential oversight |
| Interest rate | Negotiable between parties (NCA caps may apply) | Linked to prime rate; standardised |
| Approval process | Parties negotiate directly; no credit committee | Formal application, credit scoring, affordability assessment |
| Flexibility of terms | Highly flexible — bespoke terms possible | Standardised terms with limited negotiation |
| Registration process | Identical — registered by conveyancer at Deeds Office | Identical — registered by conveyancer at Deeds Office |
| Insolvency ranking | Secured creditor (identical ranking) | Secured creditor |
| Typical use | Seller financing, family loans, trust lending, private credit | Home loans, commercial property finance |
Key takeaway: A private bond provides exactly the same legal security as a bank mortgage bond. The difference lies in the commercial context: private bonds offer greater flexibility in terms and approval, but lack the institutional infrastructure, regulatory consumer protection, and standardised processes that come with bank lending. Both instruments create identical real rights at the Deeds Office.
National Credit Act Compliance
The National Credit Act 34 of 2005 (NCA) is the single most important regulatory consideration for private bond transactions — and it is the area where the most serious mistakes are made. Many private lenders are unaware that the NCA may apply to them, and non-compliance can have devastating consequences: the credit agreement may be declared unlawful, the interest may be forfeited, and the lender may face criminal prosecution.
When Does the NCA Apply?
The NCA applies to every credit agreement where the credit provider provides credit in the ordinary course of business. Under section 40(1) of the NCA, a person who provides credit must register as a credit provider if they are the credit provider under at least one credit agreement. The critical question is whether the lending constitutes "business" activity.
- Regular lending: If you provide credit to multiple borrowers, or lending is part of your investment strategy, you are almost certainly operating in the ordinary course of business and must register as a credit provider
- Incidental lending: A single once-off loan — such as a parent lending to a child, or a seller financing one property sale — may fall outside the NCA if the lender is not in the business of providing credit. However, this is a factual determination and should be assessed carefully
- Threshold: Under the NCA regulations, a person who has entered into five or more credit agreements, or whose total principal debt owed to them exceeds R500,000, must register as a credit provider
Consequences of Non-Compliance
- •Credit agreement may be declared unlawful and void
- •Lender may forfeit all interest charged — retaining only the capital
- •Lender may face administrative penalties from the National Credit Regulator
- •Criminal prosecution for reckless credit granting
- •Bond may become unenforceable against the borrower
Interest Rate Implications
- •If the NCA applies, the interest rate is capped at the prescribed maximum under section 105
- •For mortgage agreements: maximum is the repo rate + 14% per annum
- •Even if the NCA does not apply, the Usury Act 73 of 1968 may still cap the interest rate on certain transactions
- •Interest-free loans between family members are permissible but may trigger section 7C deemed donation provisions under the Income Tax Act
Practical Recommendation
Every private bond transaction should include a formal assessment of NCA applicability before the loan agreement is signed. The assessment should consider the lender's lending history, the nature of the transaction, and whether registration as a credit provider is required. Getting this wrong can invalidate the entire transaction and expose the lender to significant financial and criminal liability. A conveyancer experienced in private bonds will conduct this assessment as part of the instruction process.
Key Legislation
Four Acts of Parliament form the legislative framework for private bonds in South Africa. Understanding their interaction is essential for structuring a private bond transaction that is legally compliant and enforceable.
Deeds Registries Act 47 of 1937
The primary statute governing the registration of all bonds over immovable property in South Africa. This Act prescribes the forms, procedures, and requirements for registering a private bond at the Deeds Office. It makes no distinction between bank-held and privately-held bonds — both follow identical registration requirements. Key provisions include:
- •Section 50: Requirements for the form and content of mortgage bonds
- •Section 56: Registration of mortgage bonds and the creation of real rights
- •Section 3: Deeds must be registered by a conveyancer admitted to practise
- •Prescribed tariff: The sliding scale for conveyancing fees on bond registration
National Credit Act 34 of 2005
Regulates the granting of credit in South Africa and may apply to the underlying loan agreement secured by a private bond. The NCA's application depends on whether the lender provides credit in the ordinary course of business. Where the NCA applies, it prescribes:
- •Section 40(1): Credit provider registration requirements
- •Section 81: Reckless credit assessment obligations
- •Section 105: Maximum prescribed interest rates for mortgage agreements
- •Section 89: Consequences of unlawful credit agreements — agreement may be declared void
Alienation of Land Act 68 of 1981
Governs instalment sale agreements of land where the purchase price is payable in more than two instalments over more than one year. This Act is particularly relevant to seller-financed transactions where the seller retains ownership until full payment (as an alternative to a kustingsbrief structure). The Act provides purchaser protections including:
- •Section 19: Requirements for the form and content of instalment sale agreements
- •Section 20: Protections against forfeiture and the purchaser's right to cure default
- •Section 27: Obligation to transfer once purchase price is paid
Insolvency Act 24 of 1936
Determines how creditors are ranked and paid when a debtor is declared insolvent. A registered private bondholder is a secured creditor — ranking at the top of the insolvency waterfall. This means the bondholder has a preferential claim against the proceeds of the bonded property, ahead of preferent creditors and concurrent (unsecured) creditors. This secured creditor status is one of the primary reasons for registering a private bond rather than relying on an unsecured loan agreement.
Frequently Asked Questions
These are the questions we are asked most frequently by property buyers, sellers, families, and private lenders about private bonds in South Africa.
1What is a private bond in South Africa?
A private bond (also called a private mortgage bond) is a mortgage bond registered over immovable property where the lender is a private individual, family member, trust, or company — rather than a bank or registered financial institution. It is registered at the Deeds Office by a conveyancer and creates a real right of security, giving the bondholder secured creditor status identical to that of a bank.
2What is a kustingsbrief?
A kustingsbrief is a type of private bond where the seller of immovable property finances the purchaser directly. The property transfers to the buyer's name, and the seller simultaneously registers a mortgage bond over it to secure the unpaid balance of the purchase price. It is one of the oldest security instruments in South African law, derived from Roman-Dutch law, and is sometimes called a 'seller's bond' or 'vendor's mortgage'.
3How does a private bond differ from a bank mortgage bond?
The legal instrument is identical — both are mortgage bonds registered over immovable property at the Deeds Office, creating real rights and secured creditor status. The difference is the identity of the lender: a private person, trust, or entity instead of a bank. Private bonds offer greater flexibility in terms and approval, but the lender must independently assess National Credit Act compliance, and the borrower loses the consumer protections that come with regulated bank lending.
4How long does private bond registration take?
From instruction to registration at the Deeds Office, the process typically takes 8 to 12 weeks when registered simultaneously with a property transfer. A stand-alone private bond (registered over an already-transferred property) can be completed in 4 to 6 weeks. The timeline depends on Deeds Office processing times, municipality clearance, and the completeness of documentation.
5What does it cost to register a private bond?
Costs include conveyancing fees (calculated on the Law Society prescribed sliding scale), Deeds Office registration fees, disbursements, and 15% VAT. For a typical private bond, total costs range from approximately R10,000 to R30,000 or more depending on the bond value and complexity. The conveyancer cannot charge less than the prescribed tariff.
6Does the National Credit Act apply to private bonds?
It depends on whether the lender provides credit in the ordinary course of business. Regular or repeat lending almost certainly triggers NCA obligations, including credit provider registration under section 40(1). Single once-off loans between family members may be exempt, but this is a factual determination that must be assessed in every transaction. Non-compliance can result in the credit agreement being declared void and the lender forfeiting all interest.
7Can a private bond be cancelled?
Yes. Once the debt is repaid in full, the bondholder issues a consent to cancellation. The conveyancer prepares cancellation documents for registration at the Deeds Office. The borrower has a legal right to demand cancellation once the debt is settled. The bondholder cannot unreasonably withhold consent to cancellation.
8What happens if the borrower defaults on a private bond?
The private bondholder can apply to court for an order declaring the property specially executable. The property is sold at a public auction (sale in execution) conducted by the Sheriff, and the bondholder is paid from the proceeds as a secured creditor. The process requires strict compliance with court procedures, and the borrower has the right to cure the default before the sale takes place.
9Can a trust register a private bond over property?
Yes. A trust can act as the lender and register a private mortgage bond over immovable property. This is common in estate planning and family wealth structures. The trustees must act within their authority under the trust deed, and if the borrower is a beneficiary of the trust, independent trustee requirements may apply. The loan should be properly documented with market-related interest to avoid section 7C deemed donation implications.
10What is the difference between a private bond and a notarial bond?
A private bond is a mortgage bond registered over immovable property (land and buildings) with a private lender. A notarial bond is registered over movable property (vehicles, equipment, stock) and must be attested by a notary public rather than a conveyancer. They are governed by different legislation — the Deeds Registries Act for private bonds and the Security by Means of Movable Property Act for notarial bonds — and serve different security purposes.
Structuring Your Private Bond Transaction
Private bonds are versatile instruments that serve a genuine commercial need — providing secured property lending outside the banking system. Whether you are a seller financing a property sale, a parent helping a child buy their first home, a trust deploying capital, or a private lender building a secured portfolio, a properly structured and registered private bond provides the same legal protection as a bank mortgage bond.
The critical success factors are straightforward but non-negotiable: a properly drafted loan agreement, a formal assessment of National Credit Act applicability, an appropriate interest rate that complies with statutory caps, and a bond correctly prepared and registered by an experienced conveyancer. Missing any of these elements can render the transaction unenforceable — or worse, expose the lender to criminal liability.
The involvement of a conveyancer experienced in private bonds is not merely advisable — it is a legal requirement for registration and a practical necessity for navigating the intersection of the Deeds Registries Act, the National Credit Act, the Alienation of Land Act, and the Income Tax Act that applies to every private bond transaction.
