How to Regularize a House Without Escrituras: Legal Options

In Mexico it is very common to find houses that were bought years ago with a simple private contract, inherited without any probate proceedings, or built on a lot purchased on a "handshake." If you live in one of those properties and want to know how to regularize a house without escrituras (deeds), the good news is that there are several legal routes to do it, although none of them is instant. In this guide we review the most common options, their general requirements, and what to expect from each one.

Why a house ends up without escrituras

Before choosing a route to regularize, it helps to understand how the situation came about, because that determines which legal option applies. The most frequent causes are:

• Sale with a private contract: the property was paid for, but the sale was never formalized before a notary, either to save on costs or because of unfamiliarity with the process.
• Inheritance without probate proceedings: the original owner passed away and the family keeps living in the house without having started the succession process before a notary or a court.
• Irregular subdivisions or settlements: the land was sold in lots without urban development permits, so there is no master deed that can be legally subdivided.
• Chained assignments of rights: the house changed hands several times through informal assignments of rights or "traspasos" (transfers), and none of them was recorded in the Registro Público de la Propiedad (Public Property Registry).
• Loss or misplacement of the original deed: the document existed but was lost, and a certified copy or testimonio was never requested from the notary or the notarial archive.

Legal options to regularize

There is no single path: the right route depends on whether you know and can locate the registered owner, whether you have a purchase contract, and whether the irregularity stems from the land in general or only from your particular case. In general terms, these are the most commonly used alternatives.

Usucapión lawsuit (positive prescription)

Usucapión, also called positive prescription, is the most commonly used route when the original seller cannot be located or refuses to sign the deed even though the full payment was received. It is a civil lawsuit in which a judge is asked to recognize ownership in favor of the person who has possessed the property publicly, peacefully, continuously, and as an owner, for the period set by each state's civil legislation.

In general, the procedure follows these steps:

1. Gather evidence of possession: private purchase contract, payment receipts, property tax (predial) and utility bills in your name, witnesses, among others.
2. Hire an attorney to file the usucapión claim with the civil court corresponding to the property's location.
3. Serve (formally notify) the registered owner or, if they cannot be found, follow the notification-by-edict procedure authorized by the judge.
4. Carry out the trial, which includes presenting and hearing evidence, and wait for the judgment.
5. Once the judgment becomes final, record it in the Registro Público de la Propiedad so the house is placed in your name.

The required possession period and the length of the lawsuit vary considerably depending on the state and the courts' caseload; in some cases it can take just a few months and in others more than a year. That is why it is important for a local attorney to evaluate your specific file before estimating timelines.

Municipal or state regularization programs

When the problem is not individual but affects an entire colonia or subdivision (for example, settlements that arose without urban development permits), many states and municipalities have land-tenure regularization institutes or programs. These bodies — successors in several states to what the now-defunct Corett used to do at the federal level — work case by case with irregular developers, ejidos, or the original landowners to issue property titles to the occupants.

If your entire colonia lacks escrituras, it is advisable to:

• Find out whether a state land regularization institute or an equivalent municipal agency exists.
• Organize with your neighbors, since these programs usually move forward by entire polygons or blocks, not individually.
• Gather proof of how long the property has been occupied (electricity and water bills, predial receipts, neighborhood assembly minutes, etc.).
• Ask about the costs and subsidies available, which in some programs are reduced or tiered according to the applicant's economic situation.

These processes tend to be slower than an individual lawsuit because they depend on administrative procedures and, at times, on the program's budget availability, but they can also turn out to be cheaper than litigation.

Documents worth gathering

Regardless of the route you take, having a complete file speeds up any process. These are the most useful documents:

• Private purchase contract, assignment of rights, or any document that proves the original transaction.
• Payment receipts for the property, bank transfers, or any evidence that the agreed price was paid.
• Predial and utility (water, electricity) receipts in your name or that of the occupant, as old as possible.
• Official ID and CURP of the person seeking to regularize, as well as their RFC and tax status certificate (constancia de situación fiscal) if applicable.
• A sketch or plan of the property, if one is available, and any available cadastral data.
• Death certificates and documents proving family relationship, in cases of inheritance without probate proceedings.
• Witnesses who can testify to the continuous possession of the property, in the case of usucapión.

Risks of not regularizing

Putting off regularization may seem harmless while you live peacefully in the house, but it carries real risks worth keeping in mind.

Frequently asked questions

How long does it take to regularize a house without escrituras?

It depends on the route and the state. Direct deeding with the original owner can be resolved in weeks, while a usucapión lawsuit usually takes several months and even more than a year. Municipal or state regularization programs can also drag on due to their administrative nature. Consult a local attorney for a realistic estimate of your case.

Can I get escrituras if I only have a private purchase contract?

Yes, as long as the original seller or their heirs agree and are available to sign before a notary. The notary will review the contract, the registry history, and other documentation to determine whether it is possible to formalize the transfer directly or whether another route, such as usucapión, is more appropriate.

What is usucapión and when does it apply?

It is a civil lawsuit through which a judge recognizes as owner the person who has possessed a property publicly, peacefully, and continuously for the period required by each state's law. It is typically used when the registered owner cannot be located or when they refuse to sign the deed even though the property was paid for.

Are there free or low-cost programs to regularize?

In some states and municipalities there are land regularization institutes with reduced or subsidized costs, especially for entire colonias or subdivisions that arose without permits. Availability, requirements, and costs vary by state, so it is best to consult directly with the corresponding local agency.
