Power of attorney signed in Thailand for use in United States
A mandate signed in Thailand for use in the United States is governed by state law, not one federal rule. Real-estate and closing documents must follow the wording and form of the state where the property sits.

The certification chain step by step
- Always obtain the form from the title company, escrow agent or attorney in the destination state first.
- Sign before a Notarial Services Attorney in Thailand, or before a US consular officer in Thailand.
- If certified in Thailand, add Department of Consular Affairs certification and follow the route the destination state accepts.
- Ship originals by a tracked courier — closings normally require wet-ink originals.
Common use cases
- Selling or refinancing US property
- Bank and brokerage matters
- Estate and probate
- IRS filings by an agent
Before you start
- Confirm whether the recipient needs an acknowledgment or a jurat certificate — the wording differs.
- Check witness requirements; some states require two witnesses on real-property documents.
- Match the name spelling to the US deed or account record, not only to the passport.
Cautions and common rejection causes
- Internet templates frequently fail title-company review.
- Scans are usually not accepted at closing; originals are required.
- Mandates older than three to six months are often sent back to be re-executed.
We pre-check files to reduce the chance of rejection; the receiving authority alone decides acceptance.
