Does a Florida durable power of attorney expire?
No. A Florida durable power of attorney does not expire on a calendar date by itself. Here is what Florida Chapter 709 says for document prep. This is not legal advice.
A Florida durable power of attorney stays in force until one of the events in Florida Statutes § 709.2109 happens: the principal dies, the principal revokes it, a court finds the principal incapacitated and does not keep the agent's powers in place, its purpose is done, it reaches an end date written into it, or the last named agent can no longer serve and no successor is named. A form that never states an end date does not silently expire just because months passed.
Durability is a different question. Under § 709.2104, durability language keeps the agent's authority going through later incapacity. It does not create an expiration clock, and it does not survive death. If none of those events has happened, a durable document signed years ago still works after a hospital stay. A bank that worries the paper is old can ask the agent to sign an affidavit saying the principal is alive and the power of attorney has not been revoked or ended. The common surprise is the opposite of expiration: authority can begin at signing under § 709.2108, so the paper is already usable while the principal is healthy.
If you want a hard stop, put it in the document. Section 709.2109(1)(e) lets the power of attorney say when it terminates.
