If you live in Texas and need to buy, sell, or manage real estate in Colombia, you will likely need a power of attorney so someone there can sign on your behalf. Colombia is a Hague Apostille member, so an apostille has a role here, but there is a critical trap: for a general property-sale power of attorney, a document that is merely notarized and apostilled is not accepted. Colombian law requires that kind of power to be granted as an escritura pública. Understanding which type of power you need is the difference between a clean closing and a rejected document.
