Duration depends on the type of power of attorney you create

A power of attorney in Texas lasts as long as you want it to, but the length depends on which type you sign. A durable power of attorney stays in effect for your entire lifetime unless you revoke it in writing — even if you become incapacitated. A non-durable power of attorney ends the moment you become mentally incapacitated or, if you set an end date, on that date. A springing power of attorney (durable but triggered by a future event, like your incapacity) only takes effect when that event happens and then lasts for life.

Most people in Texas choose a durable power of attorney because it continues to work if they become unable to manage their own affairs. Without it, a family member would have to go to court and ask a judge to appoint a conservator — a slower and more expensive process. The key difference is whether the document says "durable" on it. If it does not use that word, Texas law assumes it is non-durable and ends if you lose mental capacity.

Key Takeaways

  • A durable power of attorney lasts your entire life unless you cancel it in writing, even if you become incapacitated.
  • A non-durable power of attorney ends when ready if you become mentally incapacitated or on a date you set in the document.
  • The document must say "durable" to survive your incapacity; Texas does not assume durability if the word is missing.
  • You can end any power of attorney at any time by signing a written revocation and giving copies to your agent and anyone who has relied on it.
  • Your agent's authority ends when you die, regardless of the type — a power of attorney has no effect on your estate after death.

What happens when you become incapacitated

If you sign a durable power of attorney and later become unable to make decisions, your agent can continue acting on your behalf without going to court. This is the main reason people use durable documents. Your agent can pay bills, manage bank accounts, sell property, and handle other financial matters as if they were you — all based on the power of attorney alone.

If your power of attorney is non-durable, it stops working the moment a doctor determines you lack mental capacity. At that point, your family would need to petition a Texas court for a conservatorship, which takes weeks or months and costs money in court fees and attorney fees. The court then appoints someone (usually a family member) to manage your affairs, but only after a judge reviews the case.

How to end a power of attorney before it naturally expires

You can revoke a power of attorney at any time while you are mentally capable of understanding what you are doing. Texas law requires you to sign a written revocation — a straightforward document that says you are canceling the power of attorney. You do not need a lawyer to write it, but the document should be notarized to match the formality of the original power of attorney.

After you sign the revocation, give copies to your agent and to anyone who has already relied on the power of attorney, such as your bank or investment firm. Tell them in writing that the document is no longer valid. If you do not notify them and your agent continues to act, the bank or firm may still honor the old power of attorney because they did not know it was revoked. Keeping a paper trail protects you and makes clear when the authority ended.

What happens to a power of attorney when you die

A power of attorney ends automatically when you die. Your agent has no authority after your death, even if the document says it is durable. At that point, your estate is handled by your executor (the person named in your will) or, if you have no will, by an administrator appointed by the court.

This is why a power of attorney is different from a will or a living trust. A power of attorney is only for managing your affairs while you are alive. If you want someone to handle your finances after you die without going through probate court, you need a living trust or a transfer-on-death deed, not a power of attorney.

Durable versus non-durable: which one you probably need

Most people should use a durable power of attorney. It gives you peace of mind because your agent can step in if you have a stroke, accident, or illness that leaves you unable to manage money. Without it, your family has no legal way to pay your bills or access your accounts unless they go to court.

A non-durable power of attorney is rarely useful in Texas. It might make sense only if you need someone to handle a specific task for a short time — for example, signing a real estate closing if you cannot attend in person — and you want the authority to end automatically after that task is done. Even then, a durable power of attorney with a specific end date is usually clearer.

How long your agent can act after you sign

If you sign a durable power of attorney today, your agent can begin using it when ready — the same day you sign it. There is no waiting period. Your agent can walk into your bank tomorrow and conduct transactions on your behalf, as long as the bank accepts the document.

Some banks and investment firms have their own power of attorney forms and may ask your agent to use theirs instead of yours. This is legal, and your agent can sign their form if you agree. However, if you want your agent to use your document, give them a certified copy (stamped by a notary) so financial institutions are more likely to accept it without asking questions.

Springing powers of attorney and when they take effect

A springing power of attorney is durable but does not become active until a specific event occurs — usually your incapacity. For example, you might sign a springing power of attorney that says your agent can only act if two doctors certify that you cannot make decisions. Until that happens, your agent has no authority.

Springing powers of attorney sound appealing because you keep full control until you need help. However, they create practical problems. When your agent tries to use it, banks and other institutions may refuse because they cannot easily verify that the triggering event has occurred. A regular durable power of attorney, which is active when ready, is usually easier for your agent to use and less likely to be questioned.

Frequently Asked Questions

Can I set an expiration date on a durable power of attorney?

Yes. You can write an end date into a durable power of attorney, and it will expire on that date even though it is durable. For example, you might create a durable power of attorney that lasts for five years. After five years, it ends automatically unless you sign a new one. This is useful if you want your agent's authority to be temporary but still survive your incapacity during that time.

What if I become incapacitated and never signed a power of attorney?

Your family would have to go to court and ask a judge to appoint a conservator to manage your finances. This process takes several weeks, costs money in court and attorney fees, and requires a doctor's statement that you lack capacity. A power of attorney avoids all of this by letting you choose your agent in advance.

Does my power of attorney work in other states?

A Texas power of attorney is usually recognized in other states, but some states have their own rules. If your agent needs to use it out of state — for example, to sell property in another state — contact that state's laws or ask a local attorney. Many states accept a certified copy of a Texas power of attorney without requiring a new one.

Can my agent use the power of attorney after I die to pay funeral expenses?

No. A power of attorney ends at death and gives your agent no authority over your estate or accounts. Funeral expenses are usually paid by your executor (named in your will) or by your family using their own funds, which they may recover from your estate later. If you want to set aside money for funeral costs, you can name a beneficiary on a bank account or life insurance policy.

What if I want to change who my agent is?

You can revoke the old power of attorney and sign a new one naming a different agent. Make sure to notify your former agent and any institutions that have relied on the old document. You do not need the old agent's permission to revoke it — you can do it unilaterally as long as you are mentally capable.
