Short answer
What you should know before deciding
The review must connect three elements: the identity of the person who agrees to guarantee, their power to be bound, and the current legal status of the property. An old deed demonstrates a history, but it does not replace a recent registration certificate nor does it resolve co-ownership, encumbrances or limitations on its own.

Work sequence
Person → obligation → title → ownership → registration status → limitations → conclusion.
The sequence avoids opening indiscriminate searches: each step must answer a question, produce evidence and leave a verifiable conclusion.
- 01Confirms identity and acceptance of the obligation.
Define in writing the objective, scope and criteria that will be used to decide.
- 02Review the relationship with the tenant.
Record who provided the information, how it was validated, the cutoff date, and any differences that require clarification.
- 03Compare the deed, title and description of the property.
Record who provided the information, how it was validated, the cutoff date, and any differences that require clarification.
- 04Request a registration certificate when the operation requires it.
Record who provided the information, how it was validated, the cutoff date, and any differences that require clarification.
- 05Identifies co-ownership, liens or restrictions.
Record who provided the information, how it was validated, the cutoff date, and any differences that require clarification.
- 06Transfer relevant points to the contractual review.
Conclude with confirmed facts, open items, limitations, and actions; avoid an opaque score.
Practical application
What to check and what to ask
Useful documents or evidence
- Official identification, CURP or RFC and proof of address of the guarantor.
- Complete, legible writing and with registration data or real folio.
- Property receipt or document that helps identify the property.
- Certificate of freedom or existence of a recent lien, when available or the operation justifies it.
- Complete power if someone will act on behalf of the owner.
Control questions
- Does the registered owner coincide with the person signing as guarantor?
- Is there co-ownership, usufruct, marital partnership or other limitation?
- Do the description and the folio correspond to the same property?
- Do liens reduce the practical usefulness of collateral?
Frequent errors
- Confusing the writing with a current photograph from the Public Registry.
- Review the property and omit the identity or capacity of the guarantor.
- Ignore co-owners or the way power is exercised.
- Promise that the asset will be executable without contractual and procedural review.
