General Power of Attorney for Acts of Ownership Mexico (Poder Notarial para Actos de Dominio)

A General Power of Attorney for Acts of Ownership Mexico (Poder Notarial para Actos de Dominio) is a formal legal instrument executed before a Notario Público under the Código Civil Federal (CCF) Article 2554 fracción I, by which the grantor (poderdante) expressly confers upon the attorney-in-fact (apoderado) the authority to sell, purchase, donate, mortgage, pledge, exchange, lease long-term, and otherwise dispose of, encumber, or transfer both real property (bienes inmuebles) and personal property (bienes muebles). This instrument addresses the most powerful and highest-risk category of authority under Mexican civil law — actos de dominio — which directly affect the ownership and capital of the grantor's estate.

CCF Article 2554 establishes a three-tier framework for powers of attorney in Mexico. The First Paragraph (Primer Párrafo) provides that a power granted in general terms only confers acts of administration (actos de administración) — day-to-day management acts that do not diminish capital. The Second Paragraph (Segundo Párrafo), corresponding to fracción I, requires an express special clause to grant acts of ownership or disposition — these are acts that transfer, encumber, or permanently alter the character of property, directly diminishing the estate's capital or changing asset ownership. The Third Paragraph addresses litigation authority separately. The Suprema Corte de Justicia de la Nación (SCJN) has confirmed through binding jurisprudencia that the absence of an express dominio clause means the apoderado cannot sell or mortgage property, regardless of how broadly general management authority is worded.

For real property transactions in Mexico, the Registro Público de la Propiedad (RPP) requires presentation of the poder notarial containing the express dominio clause before any deed of sale (escritura de compraventa), mortgage (hipoteca), donation (donación), or exchange (permuta) executed by an attorney-in-fact will be accepted for inscription. The Notario Público executing the property transaction deed verifies the poder's scope and records the testimonial notarial reference in the compraventa escritura. Without the express dominio clause, the notary is professionally and legally prohibited from executing the transaction on behalf of the absent owner.

For corporate Mexico — SA de CV, S de RL, and other LGSM entities — powers for acts of dominio are critical for property-owning companies where directors or managers need authority to execute real estate dispositions without convening a full shareholders' or partners' meeting for each transaction. The corporate power granting dominio authority must itself be based on a board or assembly resolution (acuerdo de asamblea) authorising the specific transaction or class of transactions — for major property dispositions exceeding the Consejo de Administración's delegated limits under LGSM Articles 148 and 149, assembly approval is required.

The Poder para Actos de Dominio may be structured as either a poder general (general — applicable to any property owned by the grantor) or a poder especial (special — applicable only to a specifically identified property, with reference to its folio real, clave catastral, and address). Mexican notarial practice strongly recommends the poder especial for individual property transactions, as it limits the apoderado's authority precisely and reduces the risk of the attorney-in-fact selling or mortgaging unintended assets. For corporate entities with multiple properties, a poder general para actos de dominio limited to a specified portfolio of assets is a common intermediate structure.

Inheritance, succession, and trust arrangements in Mexico frequently require dominio powers — a trustee (fiduciario) managing a fideicomiso inmobiliario (real estate trust) under the Ley General de Títulos y Operaciones de Crédito (LGTOC) must hold an express poder para actos de dominio granted by the fideicomitente (trust settlor) to execute property dispositions according to the trust's purposes. Similarly, an albacea (estate executor) appointed under a testamento público abierto requires a dominio clause to sell estate assets and distribute proceeds to heirs under the Código Civil Federal's succession provisions.

A Power of Attorney for Acts of Ownership Mexico is required whenever the owner of real or personal property in Mexico needs another person to sell, purchase, mortgage, donate, exchange, or otherwise dispose of that property on their behalf.

The poder is needed when a property owner residing abroad — whether a Mexican national or foreign national with Mexican property — cannot travel to Mexico to personally sign the compraventa escritura before the Notario Público. Without the express dominio clause, the Notario Público cannot execute the property sale deed on the absent owner's behalf, and the transaction cannot proceed. This is one of the most frequent uses of the poder para actos de dominio in Mexico's real estate market.

A Poder para Actos de Dominio is required when a company's Administrador Único or Consejo de Administración needs authority to sell or mortgage company-owned real estate (inmuebles) — for example, to raise capital, execute a sale-leaseback transaction (venta con arrendamiento), or dispose of surplus assets. The corporate resolution authorising the sale must first be adopted by the appropriate body, and the poder formalises the individual officer's authority to sign the deed.

The instrument is necessary when family members manage real property for elderly or incapacitated relatives who cannot appear before a Notario Público. In this context, the poder para actos de dominio is often combined with a power for acts of administration and may be granted by the owner while still legally capable, to be used if and when needed — a practice common in succession and estate planning for Mexican families under the Código Civil Federal's capacity provisions.

Mexican banks and mortgage lenders (instituciones de crédito) require an express dominio clause in any poder when the attorney-in-fact will execute a mortgage (hipoteca), cancel a mortgage, or sign a deed of trust (fideicomiso en garantía) on behalf of the property owner. The Ley de Instituciones de Crédito and CNBV regulations require financial institutions to verify the apoderado's authority extends to actos de dominio before completing a secured lending transaction.

The poder is also required for real estate developers (desarrolladores inmobiliarios) who need their sales representatives or legal advisers to execute compraventas on behalf of the development company for multiple units in a residential or commercial project, without requiring a board meeting signature for each individual sale under LGSM Article 149.

A valid Power of Attorney for Acts of Ownership Mexico under CCF Article 2554 fracción I must contain the following essential elements to be accepted by the Registro Público de la Propiedad, Notarios Públicos, financial institutions, and counterparties:

Grantor Identification: Full legal name, RFC, CURP, official identity document (INE/pasaporte), date and place of birth, marital status, and domicile of the grantor. For married grantors, the marital property regime (sociedad conyugal or separación de bienes) must be identified — for properties acquired under sociedad conyugal, the spouse's consent (cosentimiento conyugal) may be required under CCF Articles 162 and 2981 before the apoderado can execute a property disposition.

Attorney-in-Fact Identification: Full legal name, RFC, CURP, official identity document, and domicile of the apoderado receiving the dominio authority. The notary verifies both parties' identity and records identification data in the escritura.

Express Dominio Clause (CCF Art. 2554 Second Paragraph): The instrument must contain the express special clause granting authority for actos de dominio — this cannot be implied or derived from general management authority. The clause must specifically state that the apoderado is authorised to sell (vender), purchase (comprar), donate (donar), mortgage (hipotecar), pledge (dar en prenda), exchange (permutar), lease long-term (dar en arrendamiento por más de seis años), and otherwise encumber or transfer real and personal property (bienes inmuebles y muebles).

Property Identification (if Poder Especial): For a special power limited to a specific property, the instrument must identify the property by: folio real (RPP inscription number), clave catastral (cadastral registration number), full address, and a brief physical description. This specificity is required by the Registro Público de la Propiedad and the Notario Público executing the transaction deed.

Price and Transaction Parameters (for Poderes Especiales): Best practice — and the standard for protecting grantors — includes stating the minimum acceptable price (precio mínimo), permitted payment terms (condiciones de pago), and any other transaction parameters within which the apoderado must operate. An apoderado who sells below the minimum price may be personally liable to the grantor under CCF Article 2568.

Conjugal Consent: Where required by the applicable property regime, the spouse's express consent must be included in the instrument — either as a co-grantor or through a separate statement recorded by the notary — before the apoderado can exercise dominio authority over property subject to sociedad conyugal.

Substitution Authority: Whether the apoderado may delegate dominio authority to third parties. Dominio powers are typically granted without substitution (sin facultad de substitución) given the high-stakes nature of property dispositions — substitution of authority for dominio acts requires explicit grantor consent under CCF Article 2574.

Duration and Revocability: Standard practice for dominio powers is to grant them for a specific term tied to the transaction (e.g., valid for ninety days from the date of execution) or until the completion of the specific act authorised, with automatic expiry upon completion. Open-ended dominio powers represent significant grantor risk and should be avoided. Revocability under CCF Article 2595 must be expressly preserved.

Notarial Execution and RPP/RPC Registration: Mandatory execution as escritura pública under CCF Article 2555. For property transactions, the Registro Público de la Propiedad requires reference to the poder's escritura number, notary, and date in the compraventa deed. For corporate dominio powers, registration with the Registro Público de Comercio under LGSM is also required.
