Selling from Abroad: How a Power of Attorney Works in San Miguel
A power of attorney lets a trusted representative sign the sale of your San Miguel de Allende home when you cannot attend the closing. To protect yourself, make sure the document specifically authorizes the sale, have the closing Notario confirm it is valid, give written instructions & approve the final documents before anyone signs for you.
When do you need a power of attorney to sell in San Miguel?
If you own a home in San Miguel de Allende but live in the United States, Canada or elsewhere, you may not be able to sit at the Notario's table on closing day. A power of attorney, or poder notarial, lets someone you trust sign the escritura on your behalf so the sale can close without the trip.
Plenty of owners split their year between San Miguel & home, & a closing date rarely lines up neatly with a flight. The tool is common & reliable here, but it hands real authority to another person, so the way you set it up matters as much as who you choose to hold it.
What should you check before anyone signs for you?
Before closing, confirm three things: the power of attorney specifically authorizes the sale of your property, the closing Notario has verified it has not expired or been revoked, & you have approved the final terms in writing. Those steps protect you, your representative & the buyer alike.
- Verify the authority: the document should clearly permit your representative to sell the property, ideally identifying it. A general administrative power may not be enough for a sale.
- Confirm it is still valid: ask the closing Notario to review the power of attorney well before the signing date & confirm it has not expired or been revoked.
- Give written instructions: put the agreed price, payment terms & any conditions in writing so your representative knows exactly what you have approved.
- Approve the final documents: review & approve the closing statement & draft deed in writing before your representative signs.
Why do written instructions matter so much?
Your representative should document your instructions, & written approval before signing the closing documents is strongly recommended. A clear paper trail shows exactly what you authorized, which keeps everyone aligned if the price, dates or terms shift during the final weeks.
If a representative acts outside your instructions, they could face legal consequences, even if the sale itself remains valid. That is why a simple email chain or signed letter approving the final numbers is worth the extra day, especially when you are several time zones away & reading the draft escritura on your phone.
Does your representative take on your taxes?
Generally, a representative does not assume your tax obligations simply by signing on your behalf. Taxes from the sale, such as ISR on any capital gain, remain yours as the seller, & the Notario calculates & withholds them at closing.
That said, this should not be read as immunity from every possible liability, for you or for the person signing. Ask your Notario & a tax advisor to walk through the numbers before closing, so your representative is signing figures you already understand & approved.
Who should hold your power of attorney?
Choose a trusted family member, close friend or attorney to hold the power of attorney. Real estate agents should generally avoid personally holding powers of attorney for their clients, because it blurs the line between advising you & acting for you.
Keeping your agent in an advisory & coordinating role means someone independent is still watching the details on your side. Your agent can line up the Notario, share documents & keep the buyer informed, while the person signing answers only to you & your written instructions.
How early should you start if you live abroad?
Start as soon as you decide to sell, & ideally have the closing Notario prepare the power of attorney before the transaction reaches its final stages. Granting it from abroad can take weeks, so early coordination keeps a last-minute document issue from delaying your closing.
The Notario can tell you exactly what wording is needed & whether you can sign at a Mexican consulate near you or before a local notary with an apostille. Getting that sorted while you are still negotiating means the document is reviewed, valid & ready the day the buyer's funds arrive.
