Power of Attorney vs. Guardianship: Which Does Your Aging Parent Need?

Last updated: November 2026

A power of attorney is a legal document that allows your parent, while they can still make decisions, to name a person they trust to act for them. Guardianship is a legal process in which a court names a decision-maker after someone can no longer manage safely and has no valid power of attorney in place. Put simply, your parent chooses their power of attorney, but a judge chooses a guardian.

Most families don’t think about either one until something goes wrong. Your mom has a stroke, or your dad gets a dementia diagnosis, and suddenly the bank won’t talk to you, the hospital wants to know who can sign forms, and bills keep piling up on the kitchen table. You love your parent and you want to help, but without the right paperwork, your hands are tied.

That’s a hard place to be. The good news is that you have legal options, and the earlier you look at them, the more say your parent keeps over their own life. Below, we’ll walk through how each option works in Louisiana, how they compare, what they cost, and how to decide which one fits your family.

What Is a Power of Attorney?

A power of attorney (often shortened to POA) gives a trusted person the power to act on behalf of the principal, which is the person who signs it. The person given that power is usually called an agent, or sometimes called an attorney-in-fact. The agent’s authority to make decisions depends on what the document says. In Louisiana, this document is legally called a “mandate,” but most people and most banks still call it a POA.

The key thing to understand is that your parent creates the document while they still have the mental capacity to understand what they’re signing. They decide who their agent will be, what that person can and can’t do, and when that authority begins. Nobody goes to court, and no judge has to approve it. If you’re planning for yourself, the same idea applies: you pick someone you trust to act on your behalf.

There are several types of power of attorney, and the right one depends on what your parent needs. A general POA can cover almost all money and property issues, like paying bills, managing bank accounts, and handling taxes. A limited (or special) POA covers just one task, such as selling a house or handling a single account. A healthcare POA lets the agent make medical decisions if your parent can’t speak for themselves.

How a Power of Attorney Works in Louisiana

Here’s the part that trips up a lot of families. A standard power of attorney ends when the principal can no longer make decisions. That’s the exact moment most families need it. To keep working after your parent loses capacity, the document has to be “durable,” which means it includes specific language saying it stays in effect if they become incapacitated.

According to Louisiana Law Help, Louisiana doesn’t recognize “springing” documents that only switch on after incapacity, so the agent can usually act as soon as the document is signed. The document can still set conditions on when the agent may act. Your parent can also revoke it at any time, as long as they’re still competent. It always ends at death.

A durable power of attorney remains effective even after your parent loses capacity. That’s why, in most cases, it’s the simplest, cheapest, and least stressful way to make sure someone can step in when your parent can’t handle things alone.

What Is Guardianship? (In Louisiana, It’s Called Interdiction)

Guardianship is a court process where a judge appoints someone to make decisions for an incapacitated adult who can no longer make them safely. Louisiana uses different words than most states. Here, adult guardianship is called interdiction, and the person the court puts in charge is called a curator. A second person, called an undercurator, keeps an eye on the curator’s work.

In many states, these cases go through a probate court. In Louisiana, interdiction cases are heard in the district court for the parish where your parent lives. Court proceedings usually start when a family member files a petition, and your parent keeps important legal rights, including the right to be notified, to have a lawyer, and to object.

Louisiana law is careful here. Under Civil Code Article 389, a judge can only order full interdiction if the person can’t consistently make reasoned decisions about their care or property, or communicate those decisions, and their interests can’t be protected by less restrictive means. A power of attorney counts as one of those less restrictive options. The person asking for interdiction also has to prove the need with clear and convincing evidence.

Louisiana also allows limited interdiction. This works like a limited guardianship in other states. The curator only gets decision-making powers over the specific areas where your parent needs help, such as finances, while your parent keeps control of everything else. This protects as much of their independence as possible.

Power of Attorney vs. Guardianship: What’s the Difference?

The main difference between guardianship and power of attorney comes down to who makes the choice. With a POA, your parent picks their own agent ahead of time. With guardianship, a judge decides who gets decision-making authority after your parent has already lost the ability to choose. That one difference shapes everything else, from cost to privacy to how much control your parent keeps.

A POA is faster, cheaper, and private. It also respects your parent’s autonomy, because they’re the one making the choice. Guardianship takes longer and costs more, but it comes with court supervision, which can protect a vulnerable person when there’s no one they’ve chosen, when family members disagree, or when an agent isn’t acting in good faith.

When Might Guardianship Be Necessary After Incapacity?

Even though a POA is usually the better path, guardianship may be the only option left in some cases. In general, guardianship becomes necessary when someone can no longer make safe choices and no one has legal authority to help. The most common case is simple: your parent never signed a power of attorney, and now they can’t. Maybe dementia has progressed too far, or a sudden stroke or head injury has taken away their ability to understand legal documents. Once someone can’t manage their own affairs and has nothing in writing, a court has to step in.

Interdiction can also make sense when an existing POA isn’t enough. The document may be too narrow, it may not be durable, or it may not cover health care. In other situations, the agent may be misusing money, or family members may be fighting over what’s best for your parent. And sometimes a parent with memory loss refuses help in ways that put them in real danger, like wandering, giving money to scammers, or living in unsafe conditions.

Every family’s situation is different, so it’s worth getting advice based on your specific circumstances before you start any court process.

Can You Have Power of Attorney and Guardianship at the Same Time?

Yes, a person can have both in place at the same time, though it isn’t common. When a judge appoints a curator, the court can limit, override, or replace the agent named in the document. Courts often keep a trusted agent involved, especially in a limited interdiction where the curator handles only certain areas. In some cases, a judge may choose the same trusted person to serve in both roles.

This is one reason families sometimes end up in court even with a POA. If the agent and other relatives disagree, or if there are signs of abuse, a judge may decide that court oversight is needed. A well-written, durable POA, along with good communication among family members, goes a long way toward avoiding guardianship proceedings altogether.

How to Establish a Power of Attorney

The process is fairly simple, but timing matters. Your parent has to be at least 18 and have enough capacity to understand what they’re signing. If your parent is in the early stages of memory loss, don’t wait. Many people with an early dementia diagnosis can still sign valid documents, but that window can close quickly.

Start with an honest, calm conversation. Ask your parent who they’d trust to handle their money and medical decisions if they ever needed help. Then meet with an estate planning attorney who can draft a durable financial document and a healthcare power of attorney that fit Louisiana law. In Louisiana, these documents must be in writing and are usually notarized. If it will be used for real estate, it also has to be signed in front of two witnesses and recorded with the parish Clerk of Court.

Once it’s signed, give copies to your parent’s bank, doctors, and other important contacts. Some banks have their own forms or review process, so it helps to check with them early rather than in the middle of a crisis.

Estate Planning: Why It Pays to Plan Ahead

A POA works best as part of a comprehensive estate plan. Along with it, most families should also think about a will, a living will, and medical forms like Louisiana’s LaPOST, which spells out your parent’s wishes for treatment near the end of life. These legal tools work together so that your parent’s choices are known and respected.

Planning for the future also protects your relationship with your parent. When decisions are written down ahead of time, adult children don’t have to guess, argue, or carry the guilt of wondering whether they made the right call. Our advance care planning services can help your family talk through these choices before they turn into emergencies.

How Much Does Each Option Cost?

Costs vary by attorney and by how complicated your parent’s situation is, but there’s usually a big gap between the two. Having an attorney draft a POA often costs a few hundred dollars, and it may be part of a larger estate planning package.

The guardianship process is far more expensive. You’ll pay legal fees for the person filing the petition, and sometimes for the attorney who represents your parent. There are also court costs, possible fees for medical evaluations, and the cost of yearly reports to the court once a curator is appointed. All told, guardianship often runs several thousand dollars or more, and contested cases cost much more. It also takes time, which can be hard when your parent needs help right away.

Frequently Asked Questions

Does a guardianship override a power of attorney?

It can. When a judge appoints a curator, the court decides how much authority the curator gets, and it can limit or end what the agent can do. In practice, if your parent has a solid, durable POA and a trustworthy agent, a court may decide interdiction isn’t needed at all.

What does a guardian do?

A guardian, called a curator in Louisiana, makes the decisions the court has put in their hands for an incapacitated adult. That can include where your parent lives, their medical care, and their financial decisions, like paying bills and managing property. The curator has to act in your parent’s best interest and usually reports to the court on a regular basis.

Can a power of attorney withdraw money from a bank account after death?

No. A POA ends the moment your parent dies. After that, the agent has no authority over their accounts. Financial matters then move through your parent’s estate. In Louisiana, that’s handled through a process called a succession, which works like probate in other states.

How much does it usually cost to set up a power of attorney?

Most families pay a few hundred dollars to have an attorney draft a POA. The cost may be higher if it’s part of a full estate plan with a will and other documents. Free or low-cost forms exist, but an attorney can make sure the document is durable and accepted by banks and doctors.

Is a power of attorney or guardianship better?

For most families, a POA is the better choice. It’s cheaper, faster, private, and lets your parent choose who will help them while they still have capacity. Guardianship is usually a last resort for when there’s no POA, the document doesn’t cover what’s needed, or your parent needs court-supervised protection.

Can you be appointed guardian if someone already has a valid power of attorney?

Yes, but the court will want a good reason. Because Louisiana law requires judges to consider other options first, you’d usually need to show that the existing power of attorney isn’t working. That could mean it doesn’t cover the decisions that need to be made, or that the agent isn’t acting in your parent’s best interest.
