If you live in Texas but need to buy, sell, or inherit real estate in South Korea, you usually cannot manage the closing yourself from abroad. Instead, you sign a power of attorney authorizing a trusted person or lawyer in Korea to act for you and complete the transfer at the local registry office. Getting that document to work in Korea is where most people get stuck, because a defective power of attorney can stall the registration entirely.
This page explains how to prepare a Texas power of attorney that a Korean registry office will accept.
What an apostille is
An apostille is a certificate that authenticates a public document — a notary's signature, a court seal, a registrar's certification — so it will be accepted by authorities in another country. For countries in the Hague Apostille Convention, the apostille is the finish line. For countries outside it, the same Texas certificate is the first step in a short legalization chain.
Does an apostille work in South Korea?
Yes. South Korea is a member of the Hague Apostille Convention, so a Texas document carrying a Texas apostille is recognized in Korea without further consular legalization. You do not need to visit a Korean consulate to authenticate an already-apostilled U.S. document.
Keep in mind that an apostille only authenticates the U.S. notary's signature. It does not fix a power of attorney that is too vague to complete a property registration, and any English document will need a certified Korean translation.
How the Texas Secretary of State apostille works
Texas apostilles come from a single office: the Secretary of State's Authentications Unit in Austin. There is no county-clerk step — a document notarized by any Texas notary, in any of the 254 counties, goes straight to the state. Since October 2023 Texas issues one Universal Apostille (Form 2102) that works for every destination, whether or not the country belongs to the Hague Apostille Convention.
The state fee is $15 per document. Mailed requests can take up to 25 business days; in-person and appointment service in Austin is same-day for up to 10 documents, and a bulk drop-box handles larger batches in 24–48 hours. There is no online submission — every request is handled by mail or in person. Certified copies of vital records (birth, death, marriage, divorce) must be less than five years old.
