General information, not legal advice. We are notaries public, translators, and a document service — not attorneys. A California notary public cannot draft your power of attorney, cannot tell you which type you need, and cannot explain its legal effect. That guidance comes from an attorney or a notario in Mexico.
If you are caring for a parent here in the United States and they still own a house, land, or bank accounts in Mexico, there is a document that has to be signed while they can still understand what they are signing.
It is called a poder general — a general power of attorney. It is how your mother or father authorizes you to act for them in Mexico: to sell, to collect, to rent, to handle paperwork on their behalf.
Most families do not think about it until something has already changed. That is the problem this article is about.
The requirement almost nobody mentions
The person signing has to have capacity. In plain terms: they must understand what the document is, what powers they are giving away, and to whom.
A notary public is required to confirm the signer is willing and aware. If your mother has begun to show signs of dementia — if she does not recognize you, or cannot follow what is being explained — the notarization cannot proceed. Not because the notary is being difficult, but because the law does not allow it.
This is not a judgment call a family makes. It is made in the moment, by the notary, at the table.
What happens if you wait too long
If capacity is gone, the poder is no longer available. The family's remaining option in Mexico is a court proceeding — a guardianship or interdiction case, depending on the state and the circumstances.
Families we have worked with describe the same pattern: it costs thousands of dollars, it requires an attorney in Mexico, and it can take years. Meanwhile the property sits. Taxes accrue. Sometimes a buyer walks away.
All of it traces back to an afternoon that never happened.
The window is now, not later
The uncomfortable truth is that the right time to sign a poder is before anyone thinks it is necessary — while your parent is healthy, lucid, and not under any pressure.
A poder can be revoked. It can be limited to a single property or a single transaction. It can be written to expire. It is not a surrender of control; it is a backup that exists in case control becomes impossible.
What is actually involved
The document itself is usually signed in one visit. What takes planning is knowing which document you need.
The type of poder depends on what is being done in Mexico and where. A sale of real property is not the same as closing a bank account, and requirements vary by state. That is why we coordinate with the attorney or notario in Mexico first — so the document that gets signed here is the one that will actually be accepted there.
Once that is settled, the sequence is straightforward:
- Preparation — the document is drafted to the specification the Mexican side provides.
- Notarization — your parent signs in front of a notary public, with valid photo identification.
- Apostille — the California Secretary of State authenticates the notary's signature so the document is recognized in Mexico.
- Translation — a certified Spanish translation, where the receiving party requires one.
We handle the preparation, the notarization, the apostille, and the translation in one place. What we cannot do — and no notary in California can — is decide for you which powers the document should contain.
If your parent is already showing signs
Talk to an attorney in Mexico now rather than later. Capacity is not always all or nothing, and in some situations a medical evaluation at the time of signing can support that the person understood what they were doing.
But do not assume it will be fine. Bring it up while the answer is still yes.
Bring this to us
If you are not sure whether your family needs a poder, or which kind, come in and describe the situation. We will tell you what we can prepare, what needs to come from Mexico, and what it costs before you commit to anything.
Start Before It Becomes Urgent
We coordinate with the attorney or notario in Mexico, prepare the document, notarize it, and apostille it. Bilingual, in Westminster since 1999.
