How does cross-border inheritance work between Texas and Mexico?

Why does cross-border inheritance involve two separate processes?

Inheritance law is territorial. The legal process that transfers a deceased person's assets to their heirs is determined by the law of the place where each asset is located, not by the decedent's nationality or place of death.

Real estate in Texas passes through Texas law, whether through a Texas will admitted to probate in Harris County or through a revocable trust that holds the property. Real estate in Mexico passes through Mexican succession law, whether through a Mexican will or through the intestacy rules that apply when no will exists.

Financial accounts follow the same principle. A US bank account is administered under US law. A Mexican bank account is administered under Mexican banking and inheritance rules. The heirs of a bi-national estate may need to initiate and complete two entirely separate legal proceedings, potentially in two languages, before all assets are distributed.

How does Texas handle the US side of a cross-border estate?

For Texas-sited assets, the process follows the Texas Estates Code. If the decedent had a Texas will, it is admitted to probate in the county where the decedent resided. Texas allows for independent administration, which gives the executor authority to administer the estate without ongoing court supervision, reducing both cost and delay.

If the decedent had a revocable living trust that holds Texas assets, those assets typically pass outside of probate through the trust administration process. The successor trustee administers and distributes the trust assets according to the trust terms.

Assets held in joint tenancy with right of survivorship, in payable-on-death accounts, or through beneficiary designations also pass outside of the Texas probate process. For a bi-national estate, properly titling US assets so they pass efficiently is part of the planning process.

When no will exists and no trust or beneficiary designation covers an asset, Texas intestacy law determines who inherits. The Texas intestacy rules apply the same way regardless of whether the decedent also held assets in another country.

What happens to Mexico-sited assets when a US citizen dies?

Mexico-sited assets, including real property and Mexican bank or investment accounts, are governed by Mexican law for succession purposes. A Texas will does not automatically transfer Mexican real estate. Mexican law determines who inherits, what process must be followed, and what documentation is required.

If the decedent had a Mexican will (testamento), that document is used to initiate the succession process before a Mexican notary public or court, depending on the circumstances. If no Mexican will exists, Mexican intestacy law applies.

For real property held through a fideicomiso (a Mexican bank trust), the succession of the fideicomiso interest is addressed through the fideicomiso agreement itself and the designated successor beneficiaries named within it. The Mexican bank, as trustee, transfers the beneficial interest to the designated successors according to the fideicomiso terms and applicable Mexican law.

These processes require the involvement of a Mexican attorney who is licensed to practice in Mexico and familiar with the applicable state and federal succession rules. Edison Legal handles the US-law side and coordinates with Mexican counsel for the Mexico-side process.

What US tax considerations apply to cross-border inheritance?

The United States imposes a federal estate tax on the worldwide assets of US citizens and domiciliaries. This means that a US citizen's Mexican real estate, fideicomiso interest, and Mexican financial accounts are included in the gross estate for federal estate tax purposes, along with all US assets.

The federal estate tax applies above the applicable exemption threshold. For estates below the threshold, the tax does not apply. For larger estates, the tax rate can be significant, and planning to reduce the taxable estate is an important component of pre-death planning.

The United States and Mexico do not have an estate and gift tax treaty. Tax treaty benefits that apply to income taxes between the two countries do not extend to estate tax. Each country's estate or inheritance tax rules apply independently.

Mexico does not impose a federal inheritance or estate tax in the traditional sense. However, heirs who receive assets through inheritance may have income tax obligations depending on how the transfer is characterized under Mexican tax rules. This is a question for qualified Mexican tax counsel.

How does planning before death simplify cross-border inheritance?

The most effective way to simplify cross-border inheritance is to plan before it becomes a problem.

1. Prepare US and Mexican succession documents. A Texas will or revocable trust covers the US side. A Mexican will or properly designated fideicomiso beneficiaries cover the Mexican side. Both documents should be reviewed together for consistency.
2. Title assets correctly. US assets held in a revocable trust, with beneficiary designations, or in joint tenancy pass without Texas probate. Mexican assets held through a fideicomiso with a current beneficiary designation pass through the fideicomiso succession mechanism.
3. Identify and address reporting obligations. Annual FBAR and Form 8938 compliance during life simplifies the estate administration after death. Executors and trustees need to account for all foreign accounts, and pre-death compliance reduces the risk of penalties being assessed against the estate.
4. Communicate the plan to successors. Heirs who know where to find the US and Mexican documents, who the attorneys are on each side, and what assets exist in each country can initiate both processes promptly. A bi-national estate that surprises the heirs is harder to administer.
