What Everyone Gets Wrong About Power of Attorney
If you can't sign and have no power of attorney, your family may need a court to handle your money. Being married doesn't fix that. Here's what to know.

The worst time to need a power of attorney is the day you can't sign one.
Most people think of it as paperwork they'll get to later. Or something their spouse already covers. Neither is true.
What happens if you can't sign
A financial power of attorney lets someone you choose, your agent, handle your money for you. Pay the bills. Talk to the bank. Deal with the mortgage. Sign when you can't.
But you have to sign it while you still can. Utah law requires you to understand that you're naming someone to handle your financial affairs, and you sign it in front of a notary.
After a stroke, a bad accident, or advanced dementia, that window can close fast. There's no form your family can sign for you after the fact.
So if there's no power of attorney, your family usually has to go to court. In Utah, a judge can appoint a conservator to manage your money, or a guardian to make personal decisions for you. That means filings, a hearing, and court oversight from then on. It takes time and money, and the bills don't wait.
Your spouse isn't automatically your agent
This is the one that surprises people most.
Being married doesn't give your spouse legal authority over things in your name. If an account is joint, they can usually keep using it. But your IRA or 401(k) is yours alone. So is any account or car titled only to you. And if the house is in both names, selling or refinancing it generally takes both signatures.
Without a power of attorney, your spouse can end up at the same bank counter as everyone else, being told to come back with court papers.
It stops when you die
The other half of the myth runs the opposite way. People assume the agent can keep handling things after death.
They can't. Utah law says a power of attorney ends when you die. From then on, your will or trust takes over, and the person in charge is your personal representative or trustee, not your agent.
So a power of attorney doesn't replace a will or a trust. It covers your life. Those cover what happens after.
Durable is the default, but read yours
In Utah, a power of attorney is durable unless it says otherwise. Durable means it keeps working after you lose capacity, which is the whole point.
Older documents, or ones signed in another state, may read differently. Some only kick in after a doctor signs off. Some name one agent and no backup. And under Utah law, if your spouse is your agent, filing for divorce generally ends their authority unless the document says otherwise.
If yours has been sitting in a drawer for years, pull it out and read it.
What to actually do
Sign a financial power of attorney while you're healthy. Name someone you trust, and name a backup.
Do the medical side too. That's a separate document in Utah, and I wrote about Utah's new advance healthcare directive here.
A power of attorney is one of the five documents I think every family needs. If you want a quick way to see what you have and what's missing, grab my estate planning checklist.
