Family Governance: How to Preserve Wealth Across Generations

Preserving wealth across generations depends on rules agreed while you are alive: a shareholders' or quotaholders' agreement for the company, a family protocol for decisions, a donation with reserved usufruct to transfer assets, and inalienability clauses within the limits of arts. 1,848 and 1,911 of the Brazilian Civil Code.

What is family governance, and why does it come before the structure?

Family governance is the set of rules that defines who decides, who manages, and how the family enters and leaves the estate. It comes before the structure because a holding company or an offshore company organizes the assets, but neither one decides on its own who makes the decisions about them.

In this guide, a "family protocol" is the internal document that records those rules: criteria for heirs to work in the company, profit distribution policy, conflict resolution, and partner exits. The legal effects depend on the rule appearing in an instrument the law recognizes, such as the articles of association, a shareholders' agreement, or a will.

The focus here is the governance layer. The choice between a holding company and an offshore is covered in Holding or Offshore: Which to Choose in 2026?, and the topic of probate and trusts is covered in Offshore and succession: how to avoid probate. This text does not repeat those two.

How does a shareholders' or quotaholders' agreement work?

A shareholders' agreement sets, by contract, rules that the bylaws or articles of association do not cover: preference on the sale of shares, the exercise of voting rights, and the entry of heirs. In corporations (sociedades anônimas), Law No. 6,404/1976 (Lei 6.404/1976), art. 118, requires the company to observe agreements on the purchase and sale of shares, preference, voting, and control when they are filed at the company's headquarters.

That same art. 118 has three practical effects:

• •the agreement can only be enforced against third parties after it is annotated in the registry books and on the share certificates, if issued (§ 1);
• •shareholders can request specific performance of the obligations assumed (§ 3);
• •the agreement does not release the shareholder from liability in exercising the vote or controlling power (§ 2).

In a limited liability company, the Civil Code says the articles of association may provide for supplementary governance by the rules of the corporation (art. 1,053, sole paragraph). Without such a provision in the contract, a partner may assign the quota to another partner without consulting the others, or to an outsider if holders of more than one quarter of the share capital do not object (art. 1,057). The assignment is only effective against the company and third parties after the instrument is annotated.

Clauses that families usually negotiate:

What can a family protocol regulate, and what can it not?

A protocol can organize how the family and the company coexist, but it cannot turn the inheritance of a living person into the object of a contract. Art. 426 of the Civil Code is clear: the inheritance of a living person cannot be the object of a contract.

In practice, this defines the division of labor among the documents:

1. •Family protocol: principles, criteria for access to the company, dividend policy, and decision forum.
2. •Shareholders' or quotaholders' agreement: what needs contractual force among the partners, such as preference and voting.
3. •Will and donation: the transfer of the assets themselves, always within the limits of the legitime (legítima).

So take to the proper legal instrument whatever needs to be enforceable in practice.

How does a donation with reserved usufruct work?

In a donation with reserved usufruct, the owner transfers ownership to the heirs but keeps the right to use the asset and receive its fruits for life. The Civil Code defines donation as the contract in which someone, out of generosity, transfers assets from their estate to another person's (art. 538).

The points of law that weigh the most:

• •Usufruct: the usufructuary has the right to possession, use, administration, and collection of the fruits (art. 1,394). For real estate, it arises with registration at the Real Estate Registry Office (art. 1,391).
• •End of usufruct: it is extinguished, among other causes, by the usufructuary's renunciation or death (art. 1,410, I). With that, full ownership passes to the donee.
• •Reserve for subsistence: a donation of all assets without reserving part of them, or enough income, for the donor's subsistence is void (art. 548).
• •Legitime limit: a donation is void to the extent it exceeds what the donor could dispose of by will (art. 549). The legitime is the half of the estate that belongs to forced heirs (art. 1,846).
• •Advancement: a donation from an ascendant to a descendant counts as an advance on what the descendant is due to inherit (art. 544). When the succession opens, the descendant brings the value received into the estate (colação, art. 2,002), unless the donor waives the collation in the deed of the gift itself, within the disposable portion (arts. 2,005 and 2,006).

A donation also generates a state tax. The Constitution gives the States and the Federal District the tax on transfers causa mortis and donations (art. 155, I, "a"), which will be progressive according to the value of the donation (art. 155, § 1, VI, added by Constitutional Amendment 132/2023). The maximum rates are set by the Senate (art. 155, § 1, IV). Check your State's law for the rate and the calculation base.

For a comparison between donating during life and leaving a will, see the section on the topic in Offshore and succession. If the assets are in a holding company, the article Taxation of the asset-holding company explains how each tax applies.

What do arts. 1,848 and 1,911 of the Civil Code allow in inalienability clauses?

Art. 1,848 prohibits the testator from imposing inalienability, unseizability, and incommunicability on the assets of the legitime, except for just cause declared in the will. Art. 1,911 says that inalienability imposed by an act of generosity, such as a donation, implies unseizability and incommunicability.

These clauses protect the asset against seizure and against being shared with the spouse, but they also lock up management. An encumbered property can only be sold with a court decision, which delays corporate reorganizations. Assess whether the protection is worth the loss of flexibility, and encumber only what needs to be encumbered.

A division of the estate made during life by the ascendant is also valid, as long as it does not harm the legitime of the forced heirs (art. 2,018).

Which instrument solves each family goal?

No single instrument solves everything. Choose by goal and combine the ones that complement each other.

If the family has assets outside Brazil, governance must take into account the rules of each jurisdiction. The guide Valid international will shows the precautions for wills and assets abroad, and OffshoreProz's tax planning service helps align the structure to your case.

How do you implement family governance step by step?

Do it in this order, with a family and succession lawyer and an accountant:

1. •Map the estate: list properties, companies, accounts, and assets abroad, with the name of whoever is the registered owner.
2. •Define the goals: protect the spouse, keep the company together, treat children equally or differently.
3. •Write the family protocol with all the members involved, so that everyone knows the rules.
4. •Formalize the shareholders' or quotaholders' agreement and, in corporations, file it at the headquarters and annotate it.
5. •Plan the transfer: donation with usufruct, will, division of the estate during life, always respecting the legitime.
6. •Calculate the tax: the state tax on donations and any federal taxes on the transaction, before signing.
7. •Review at every relevant change: marriage, divorce, birth, sale of a company, or a move to another country.
