Selling a Business With Co-Shareholders

If more than one of you is selling, there is a second negotiation running alongside the one with the buyer — the one between yourselves. It is routinely left until the week before signature.

Quick answer

1. The Second Negotiation

If you own the business with a co-founder, a family trust and a former colleague who came in at 10% in 2014, you have a second negotiation running alongside the one with the buyer: the one between yourselves. It is routinely left until the week before signature, when everyone is tired.

That timing is the mistake. Everything on this page — how liability is shared, who can block the deal, how deferred money is split, who speaks for the group — is easy to agree while the sellers are still on the same side of the table, and painful to agree once the buyer’s draft sale agreement is on the table and each seller starts reading it with their own interests in mind.

The sections below take the co-seller questions in the order of the money at stake: liability first, then power, then the split, then the mechanics of trusts and spouses, and finally the short document that keeps former partners out of court.

2. Who Pays if the Buyer Has a Claim

Start here: it is the question with the biggest number attached. If the buyer makes a warranty claim two years after closing, can they come after each of you only for your own share, or can they pick the wealthiest, most reachable seller, take the whole amount from that one person, and leave them to chase the others?

Those are genuinely different worlds:

Each liable for their own proportion

A seller is liable only for their share of the claim, matching their shareholding. The buyer must pursue each seller separately for that seller’s slice — no more.

  • Your exposure is capped at your percentage of the claim
  • Another seller’s inability to pay is the buyer’s problem, not yours

Joint and several liability

What your advisors call joint and several liability: the buyer picks who to sue, that seller pays everything, and recovering from the others is their problem.

  • The buyer picks the wealthiest, most reachable seller
  • That seller pays the whole amount and is left to chase the others

Watch out

Look at the bottom row. If your co-founder has emigrated, or the trust has distributed everything to its beneficiaries, or the 10% holder does not have R300,000, you are not carrying 60% of the risk. You are carrying all of it.

In short

Before you argue about anything else, know whether a claim can land entirely on you. On a R40 million deal that difference is worth more than the price adjustment you have been fighting about.

3. Your Shareholders’ Agreement Is Now a Deal Document

The agreement you signed with your co-owners years ago, and have not read since, matters the moment a buyer appears. (If you are still deciding what should be in one, see our shareholders’ agreement guide.)

Look for three things:

1

Pre-emption rights

These say that before shares go to an outsider they must first be offered to existing shareholders. They must be waived in writing by everyone, or the sale is defective.

2

Drag-along rights

These let a defined majority force the rest to sell on the same terms, so a holder of 8% cannot hold a R40 million deal hostage.

3

Tag-along rights

These do the opposite: they let a minority holder insist on being included rather than left behind alongside a new controlling owner.

Whether those provisions exist changes who has power in the room, and a buyer will want to see them early, because a buyer wants 100% and needs to know how to get it. If your agreement is silent, every shareholder has a veto over their own shares — worth knowing before you promise a buyer the whole company.

4. Splitting the Money — and Splitting It Again Years Later

Dividing the price is usually easy, because shareholdings are known. What gets missed is that a sale is not one payment but a series, and the later ones create the arguments.

The escrow

The escrow is released eighteen months later, and everyone must be clear whose money it is if part is paid away.

The earn-out

The earn-out is earned over two or three years, in a business only some of you still work in — a seller who stays and drives it will feel differently about sharing equally with one who left on closing day.

The claim in year three

A warranty claim paid in year three has to be funded by someone, from money already spent.

Then the asymmetries. If one of you gave the bank a personal suretyship and another did not, that should be reflected. If the tax warranties really sit within one person’s knowledge, sharing that risk by percentage may be the wrong answer.

None of it is complicated. It just has to be decided while everyone is still on the same side of the table.

5. One Voice: the Sellers’ Representative

A buyer will not negotiate with five people. If forced to, they will take the softest answer from each of you and assemble it into a position none of you agreed to.

So appoint one of you to speak for all the sellers, with genuine authority:

What the sellers’ representative handles

  • Giving and receiving notices under the sale agreement
  • Negotiating the drafting
  • Agreeing the disclosure letter
  • Handling claims after closing
  • Receiving the price for distribution to the sellers

Write the appointment down, with clear limits on what still needs everyone’s sign-off — a price reduction, a new obligation, an extension of the long stop date.

6. Trusts, and Spouses

Two traps, easy to fix early and painful to fix late.

If a family trust holds shares

The trustees sell, not the beneficiaries. The trust deed must permit it, all the trustees must act together, and the decision must be recorded in a proper resolution. If the trust does not have the number of trustees its deed requires, or one trustee has quietly not participated for three years, the buyer’s lawyers will find it and the sale of those shares can be challenged.

Trusts also carry a distinct tax consequence — see tax when selling a business.

Watch out

If a seller is an individual married in community of property, their spouse must consent in writing. That is not a formality — without it the transaction is exposed. Confirm the marital regime of every individual seller at the start.

7. The Agreement You Have With Each Other

Here is the point co-sellers most often miss. The sale agreement governs your relationship with the buyer. It says nothing useful about your relationship with each other. If the buyer recovers R3 million from you and your co-sellers owe you a share, the sale agreement does not help you collect it.

So put your arrangement with each other in a separate document, signed at the same time as the sale. It should cover:

What the inter-seller agreement records

  • How the price is split at each stage
  • How claims are shared
  • Who funds a defence, and who decides whether to fight or settle
  • What happens if one of you cannot pay
  • Whether part of each seller’s proceeds is held back for the escrow period, so money is available if a claim arrives

In short

It is a short document and costs very little. It is also the only thing between you and a lawsuit against a former partner in 2029.

8. How MJ Kotze Inc Helps

The co-seller checklist — settle these while everyone is still on the same side of the table

  • Is warranty liability proportionate, or joint and several? Know whether a claim can land entirely on you.
  • Have pre-emption rights been waived in writing by everyone? Do drag-along or tag-along rights exist — or does every shareholder hold a veto over their own shares?
  • How are the escrow release, the earn-out and any future warranty claim split — and are asymmetries (a personal suretyship, one person’s tax knowledge) reflected?
  • Is a sellers’ representative appointed in writing, with clear limits on what still needs everyone’s sign-off?
  • For any trust seller: does the deed permit the sale, are all required trustees in place and acting together, and is the decision recorded in a proper resolution?
  • For every individual seller: what is their marital regime, and is written spousal consent in place where they are married in community of property?
  • Is the inter-seller agreement drafted and ready to sign at the same time as the sale agreement?

The co-seller questions are cheap to answer early and expensive to answer late. In a multi-seller sale we review the shareholders’ agreement before the buyer does, negotiate the liability basis in the warranty schedule, paper the sellers’ representative appointment, confirm trustee resolutions and spousal consents, and draft the inter-seller agreement so it signs alongside the sale agreement rather than after the first claim.
