Partners' agreement: a practical guide to a document that brings predictability

The partners' agreement complements the articles of association and brings predictability to delicate moments. It is valuable for any partnership and, often, even more important among friends and family members.

Many people treat the articles of association as the only relevant document of the partnership and discover, too late, that it does not answer several important day-to-day questions. The partners' agreement exists precisely to fill these gaps. It is a separate contract, entered into among the partners, that organizes the relationship among them and anticipates solutions for situations that, if left open, tend to turn into conflict.

What a partners' agreement usually addresses

Each agreement is tailored, but some topics appear frequently because they are recurring sources of dispute. Clear rules on these points help prevent an isolated divergence from turning into a corporate crisis.

  • A partner's exit, including how the stake of the departing partner is valued and paid
  • The entry of new partners or investors and the conditions of that entry
  • Resolution of ties in strategic decisions to avoid paralysis of the company
  • The sale of a stake, with mechanisms that organize who may buy and under what conditions
  • Rules on confidentiality, non-competition and dedication, when they make sense for the business

Why it is insurance for the partnership

The comparison with insurance is useful: just as one does not buy insurance after the loss, the ideal moment to enter into a partners' agreement is when the relationship is good and no one foresees problems. It is in this scenario that the rules come out more balanced, because they are designed to protect the partnership as a whole, and not to favor one side in a dispute already under way.

Among friends and family, even more important

There is an impression that, among close people, formalizing rules would be a sign of distrust. In practice, it is usually the opposite. It is precisely in affectionate relationships that the strain of a conflict is greater, because it mixes business and personal ties. Having written arrangements protects the friendship and the family as much as it protects the company, by giving everyone predictability about what happens in each scenario.

Relationship with the articles of association

The partners' agreement does not replace the articles of association; the two coexist. As a rule, the articles of association deal with the formal structure of the company, while the agreement details the relationship among the partners. For this reason, it is important that the documents speak to each other and do not create contradictions, which reinforces the usefulness of a technical review.

What is the difference between the articles of association and a partners' agreement?

The articles of association are the document that formally structures the company. The partners' agreement is a contract among the partners that details the relationship among them. They complement each other and should be aligned.

Is it worth having a partners' agreement among family members?

Yes, and often it is even more important. Clear rules protect both the business and the personal relationship, reducing the risk of conflicts that mix assets and affectionate ties.
