Choose the kind of power of attorney you want to create. Select the agent you wish to represent you. Choose the authority you wish to provide your agent. Obtain an attorney-in-fact form. The Texas Health and Human Services website offers free financial POA forms, and the Texas Health and Safety Code website has a free medical POA template. Fill out, sign, and execute your POA form. When creating a financial POA, sign the paperwork in front of a notary public. Think about distributing a copy of your POA form to your agent and other parties who may be interested, such as your bank and doctor’s office. Store your POA forms safely with the rest of your estate planning papers. Update your POA as your circumstances alter.
