How to Inherit a House in Mexico: With or Without a Will

When the owner of a home passes away, the family faces two very different paths depending on whether or not there is a valid will. Inheriting a house with a will is usually a relatively quick process handled by a notary; inheriting a house without a will means going through a court proceeding (intestate succession, or "sucesión legítima") that can take longer, cost more, and create friction among heirs. In this guide we explain, step by step and in plain language, how each route works in Mexico, what documents are required, how long it can take, and which mistakes to avoid.

Inheriting with a will vs. without a will

The key difference lies in who decides how the property is divided. If the deceased left a valid public open will (testamento público abierto), that document states precisely who the heirs are and what share of the assets each receives, including the house. The notary who formalized the will (or any notary, relying on the national registry of wills, the Registro Nacional de Avisos de Testamento) can handle the succession out of court in most cases, provided the heirs agree and are of legal age.

When there is no will—or the existing one was revoked, is void, or does not cover all assets—the law determines who inherits, following an order of priority (spouse and children first, then ascendants, collateral relatives up to a certain degree, and ultimately the State). This process is called intestate succession or "ab intestato," and it normally requires a court proceeding before a family judge or, in some states, it can also be handled by a notary if all heirs are identified, legally competent, and unanimously in agreement.

The process when there is a will

The general steps, which may vary by state, usually are:

1. Obtain the death certificate and ask the national registry of wills (Registro Nacional de Avisos de Testamento, or the state equivalent) to search for a will in the deceased's name.
2. Locate the certified copy of the will with the notary who formalized it, or request a certified copy.
3. Begin the succession proceeding before a notary: the designated heirs accept the inheritance and, where applicable, an executor (albacea) is appointed.
4. The notary prepares an inventory of assets, including the house, with an appraisal and verification that there are no liens or outstanding property tax (predial) or water bills.
5. Applicable taxes and fees are paid (Mexico's income tax law, the Ley del ISR, exempts property received by inheritance or bequest from this tax regardless of the heir's relationship to the deceased, but there are notarial and registration fees and, in some states, a local tax on real estate acquisitions with special rules for successions).
6. The deed of inheritance adjudication (escritura de adjudicación hereditaria) is formalized and recorded in the Registro Público de la Propiedad in the names of the new owners.

This path is generally shorter because it does not require a judge's involvement, unless there is a dispute over the validity of the will or an heir feels their rights have been affected (for example, outstanding support obligations).

The process when there is no will (intestate)

Without a will, you must first determine legally who the heirs are, and this is precisely what the intestate proceeding resolves. The typical stages are:

1. Confirming there is no will. A certificate stating that no will exists is requested from the relevant registry.
2. Filing the intestate succession claim. A family member with a legitimate interest files it before a family court or, if all presumed heirs are legally competent and in agreement, before a notary public (this notarial route is not available in every state or in every scenario).
3. Identifying the heirs. Family relationships are proven with birth and marriage certificates and, where applicable, proof of financial dependence; public notices (edictos) are published to give other potential heirs the chance to come forward.
4. Appointing an executor (albacea). The executor manages the assets during the process and reports on them.
5. Inventory and appraisal of the assets, including the house, similar to the testate process.
6. Judgment or ruling declaring the heirs and setting their shares under the law (for example, between spouse and children, subject to the specific rules of each state's civil code).
7. Adjudication and deed transferring the house to the heirs, with recording in the Registro Público de la Propiedad.

Documents typically required

• Original death certificate and certified copies.
• Official IDs of the deceased and of the presumed heirs.
• Birth and marriage certificates or, where applicable, proof of cohabitation (concubinato) for the heirs.
• Certificate confirming the existence (or non-existence) of a will.
• Public deed (escritura pública) of the house and an up-to-date certificate of no liens (it can help to read the guide on the certificado de libertad de gravamen to understand this document).
• Proof of payment of property tax (predial) and utilities up to date.
• Appraisal of the property, generally required by the notary or the court.
• RFC and CURP of the heirs, for tax and registration procedures.

Approximate costs and timelines

Exact amounts depend on the state, the cadastral or market value of the house, and whether the process is notarial or judicial. As a rough guide, consider the following items, always subject to local confirmation:

Before committing a budget, ask the notary's office or law firm for a formal quote; and if you later plan to sell or buy another property with the inherited assets, also check the closing cost calculator to get an idea of the costs associated with a future transfer.

Common mistakes when inheriting a house

Frequently asked questions

Can you inherit a house without a will in Mexico?

Yes. When there is no will, the house is inherited through a process called intestate succession, or "ab intestato," in which the law determines who the heirs are according to an order of priority (generally spouse and children first). This procedure can be carried out before a family court or, in several states, before a notary public if all heirs are identified and in agreement.

How long does it take to inherit a house without a will?

As a rough guide, a notarial procedure with agreement among the heirs can take a few weeks to a few months; an intestate proceeding in family court, especially if there is a dispute or heirs who are hard to locate, can stretch to several months or more than a year. Exact timelines vary widely depending on the state and the complexity of the case.

What happens if several siblings inherit the same house?

The house becomes co-owned by all the heirs according to the percentage each is entitled to. To sell, rent, or mortgage it, the agreement of all co-owners is generally required, unless the property is divided or one buys out the others' shares. If there is no agreement, it may be possible in some cases to request a court-ordered sale of the property.

Are taxes paid when you inherit a house?

Income tax (ISR) is waived on property received by inheritance or bequest, and this exemption applies to any heir or legatee regardless of their relationship to the deceased, not just children or a spouse. Notarial and registration fees are usually incurred and, in some states, a local tax on real estate acquisitions with special rules or partial exemptions for successions. It is advisable to confirm current rates with a notary in the state where the property is located.
