Quick Answer
Strongly recommended. While your US will can be recognized in Mexico, the process of validating a foreign will is lengthy and expensive. A Mexican will (testamento) specifically covering your Mexico property is the most efficient approach. It costs $500-$1,500 USD to prepare and ensures your property transfers smoothly to your chosen heirs without delays.
Detailed Answer
A Mexican will (testamento) is strongly recommended for every foreign property owner, even if you have named substitute beneficiaries in your fideicomiso. While a US will can technically be recognized in Mexico, the process of validating and executing a foreign will — known as an exequatur — is lengthy, expensive, and requires translation, apostille certification, and additional court proceedings that can delay the transfer by 12-24 months. A Mexican will avoids all of this.
Preparing a Mexican will is simple and affordable, typically costing $500 to $1,500 USD through a notario publico or estate planning attorney in Los Cabos. The will specifically covers your Mexican assets (real estate, bank accounts, vehicles) and names your chosen heirs and an executor (albacea). It does not affect your US estate plan — you can have both a US will and a Mexican will, each covering assets in their respective jurisdictions. The Mexican will is registered in the National Registry of Wills for easy verification.
