Wealth trust (fideicomiso): why a will isn't enough to protect your family

A will answers a single question: who receives what when you are gone. It does not answer the important ones: who administers while your children grow up? What happens if the estate is sued beforehand? How do you keep the succession from spending years in the courts? That is what the trust (fideicomiso) is for — and that is why business families use it as the backbone, not an accessory.

What a trust is, without the jargon

You transfer assets (real estate, shares, investments) to a trustee institution — an authorized bank — with precise and binding instructions on how to administer them and to whom to deliver them, under what conditions and at what times (General Law of Negotiable Instruments and Credit Operations). You design the rules; the trustee is legally bound to execute them. You can be both settlor and beneficiary: keep the benefit of your assets during your lifetime and predefine their destination afterward.

What the trust does and the will does not

• It avoids probate. Assets placed in trust do not enter the estate: they pass according to the contract, without going through a process that in Mexico can take months to years, with fees and family conflict included.
• It protects against future creditors. Properly constituted and with the formalities met — recording in the Public Registry when there is real estate — the trust estate stays separate from the settlor's personal estate against later contingencies. It is not retroactive protection: transferring assets when a due and payable claim already exists can constitute fraud against creditors.
• It administers in your absence. Minor children? An heir who isn't yet ready to administer? The trust delivers in stages, makes delivery conditional on ages or milestones, and pays for education and expenses in the meantime. The will delivers everything, all at once, to whoever ends up being the heir.
• It gives continuity to the company. The shares of the operating company (or of the holding) inside a trust with a technical committee avoid the power vacuum between death and adjudication — the period when family companies break apart.

The tax angle, without the myths

The trust is not a tax-evasion vehicle, and anyone who sells it as "you don't pay taxes anymore" is lying. What it does offer: the transmission to the beneficiaries upon death can be structured within the tax treatment of inheritances — income exempt for individuals (art. 93 LISR) — and the contribution of certain assets can be designed so as not to trigger an immediate taxable transfer when the settlor reserves the right to reacquire them (art. 14 CFF). Each case requires analysis: the same contract with two different clauses has two different tax treatments.

Obligations that come with it: the trust must identify and document its controlling beneficiaries (arts. 32-B Ter and Quáter CFF) — settlors, beneficiaries and those who exercise control — with fines above $1.6 million pesos per beneficiary in case of non-compliance (art. 84-N CFF, amounts subject to adjustment). Protection without compliance is protection with the door left open.

Will and trust: it isn't one or the other

The correct architecture usually uses both: the trust for the strategic assets — company, core family real estate, portfolio — and the will as a safety net for everything else and for whatever accumulates later. What has no defense is relying on the will alone when you have an estate that already justifies a structure.
