Joint ventures between families: the documents that prevent the dispute.

Two families co-investing through a shared vehicle need the exit agreed while relations are good. The provisions that matter are the ones nobody expects to use, and they are the ones most often left out.

A joint venture between two families begins in the best possible conditions. The principals know each other, frequently over many years, the opportunity is agreed, and the contribution each side will make is obvious to both. It is precisely these conditions that produce the thin documentation, because the parties are reluctant to negotiate provisions that appear to anticipate a falling-out neither expects.

The provisions in question are not about mistrust. They are about the fact that circumstances change over the life of a venture: principals die, families divide, one side needs liquidity and the other does not, and a business that both parties agreed about at the outset requires a decision they disagree about in year six. A document that addresses only the successful case leaves those situations to be negotiated at the moment the parties are least able to negotiate.

The provisions that decide the outcome

Transfer restrictions come first: whether a party may sell its interest, to whom, and on what terms. Pre-emption rights giving the other side the first opportunity to buy, together with tag-along and drag-along provisions dealing with a sale of the whole, determine whether a family can find itself in business with a stranger. Without them, a change in one family’s circumstances becomes a change in the other family’s counterparty.

Reserved matters come second: the decisions that require the agreement of both parties rather than a simple majority. Changing the business, issuing further interests, incurring debt beyond a threshold, entering related-party transactions and distributing or retaining profits are the usual list. Setting it too narrowly leaves a minority exposed; setting it too broadly makes ordinary management impossible, and the balance is a genuine negotiation rather than a matter of standard form.

The provisions that determine how a venture ends are negotiated properly only while both parties still expect it to succeed.

Deadlock, and how it is resolved

A fifty-fifty venture will eventually face a decision on which the parties do not agree, and the document should say what happens then. The mechanisms are well established: escalation to the principals, then to an independent third party, and ultimately a separation mechanism under which one side acquires the other’s interest at a price determined by a stated process. Each has consequences and none is neutral.

Mechanisms in which one party names a price and the other elects to buy or sell at it are efficient and favour the party with greater liquidity, since the ability to buy is what makes the option meaningful. Independent valuation is fairer in principle and slower in practice. Which is appropriate depends on the parties’ relative resources, and choosing between them at the outset is straightforward, whereas choosing between them during a dispute is itself a dispute.

What is most often left out

Death and incapacity of a principal is the most common omission. Where an interest passes to heirs who were not party to the original arrangement and have no involvement in the business, the surviving party finds itself in a venture with people it did not choose. Provisions dealing with what happens on death — whether the interest may be inherited, whether the other party may acquire it, and at what price — belong in the document from the start.

The second omission is the treatment of contributions other than capital. Where one family contributes money and the other contributes management, relationships or access to a market, the arrangement is frequently documented as though both contributed capital, and the non-capital contribution is left to be recognised informally. When that contribution ends, because the individual providing it steps back or dies, the document contains nothing about what should happen to the interest attributed to it, and the parties are left arguing about a bargain that was never written down.
