Many owners discover that occupying, paying for or inheriting a property is not the same as having a complete registered title. In Mexico, an escritura pública is the notarial instrument commonly used to formalize a real-estate transaction, and registration gives the act publicity and effect against third parties under the applicable rules.

There is no single deed application for every unregularized property. The correct route depends on how the right arose and what the Public Registry of Property currently shows.

Begin with a title investigation

Before selecting a procedure, compare the available documents with the registry and the physical property. The initial file may include:

  • the seller's or deceased owner's prior deed;
  • a private sale agreement and proof of payment;
  • inheritance documents;
  • cadastral records and property-tax receipts;
  • a survey, subdivision or condominium documents;
  • certificates of liens and ownership; and
  • judgments or settlement agreements affecting the property.

Tax or utility receipts can support a factual history, but they do not automatically replace a deed. Likewise, a cadastral account identifies property for administrative purposes and is not necessarily proof of registered ownership.

The investigation should confirm that the description, area, boundaries and owner are consistent. A mismatch may require correction, subdivision, merger, probate, litigation or another preliminary act before a notary can formalize the intended transfer.

If the property was bought under a private contract

A private purchase agreement may create enforceable obligations between the parties, but real-estate transfers are subject to formal requirements. If the seller is available, has registered title and the transaction is otherwise valid, the parties may be able to appear before a notary to formalize the sale.

The notary reviews identity and authority, title history, liens, tax and service certificates, the property description and the transaction's tax treatment. The parties then execute the public instrument, applicable taxes and fees are paid or withheld, and the deed is submitted to the competent Public Registry of Property.

If the seller refuses, has died, lacks title or transferred the property again, a direct notarial signing may not be possible. The buyer may need a succession claim, an action to compel formalization, a title claim or another remedy based on the documents and limitation periods.

If the property was inherited

A will does not itself convert the beneficiary into the registered owner of a particular property. The succession must identify the heirs, inventory the asset, address liabilities and adjudicate it.

The adjudication is then documented through the notarial or judicial route applicable to the succession and registered. If several heirs receive interests, the resulting ownership and any partition agreement must be reflected accurately rather than assuming that one occupant became sole owner.

If ownership is claimed by prescription

Acquisitive prescription, or prescripción positiva, may recognize ownership when possession meets every requirement of the governing local law. It is not an administrative shortcut for anyone who lacks documents.

A claimant generally needs a final decision identifying the property and recognizing the acquisition. The steps required to formalize and register that decision depend on local procedure and registry rules. Evidence of peaceful, continuous, public possession as owner must be distinguished from occupation under a lease, loan or permission.

The notary and registry perform different functions

The notary verifies legality, formalizes the act, calculates or collects applicable charges and prepares the public instrument. The Public Registry records the act and makes the title situation discoverable to third parties. Completing only one side can leave the regularization unfinished.

Registration may be delayed by an existing mortgage, attachment, inconsistent owner name, missing prior registration, unpaid charges or an inaccurate property description. Those issues should be identified before the planned signing date.

Costs are specific to the transaction

Deeding a property can involve acquisition or other taxes, appraisal, certificates, registry rights, notarial fees and the cost of curing title problems. Percentages vary by state, value, transaction and available tax treatment. An estimate should come from the notary and advisers after reviewing the actual file, not from a generic online range.

Regularization creates practical value: a clear registered title can support a lawful sale, mortgage, lease and future succession. It also reduces the risk that family members or buyers inherit an unresolved chain of documents.
