Power of Attorney: The Most Dangerous Document You'll Ever Sign?

The Probate Law Center June 3, 2026

When a Power of Attorney Becomes a License to Steal

A power of attorney is one of the most important legal documents a person can sign. It is also one of the most abused.

Most people create a power of attorney because they trust someone. They want a spouse, child, sibling, or close friend to be able to help manage finances if they become sick, injured, or unable to handle their own affairs.

Unfortunately, the same document that allows someone to help can also create an opportunity for abuse.

At our office, some of the most painful family disputes begin with a power of attorney. In many cases, the document was signed with good intentions. Years later, family members are left asking what happened to the money.

The uncomfortable truth is that a power of attorney can become a license to steal when it falls into the wrong hands.

What Is a Power of Attorney?

A financial power of attorney allows one person, called the agent or attorney-in-fact, to act on behalf of another person, known as the principal.

Depending on the powers granted, the agent may be able to:

  • Access bank accounts.

  • Pay bills.

  • Manage investments.

  • Buy and sell property.

  • Sign contracts.

  • Handle insurance matters.

  • Conduct financial transactions.

Many powers of attorney become effective immediately after they are signed. This means the agent may have authority even while the principal is healthy and capable of managing their own affairs.

That authority can be incredibly useful.

It can also be incredibly dangerous.

The Perfect Opportunity

Consider what a power of attorney often provides.

The agent may have legal access to financial accounts. They may have the ability to sign documents. They may be assisting an elderly parent who trusts them completely.

In many cases, there is little oversight.

Banks generally do not monitor whether transactions benefit the principal. Family members often assume everything is being handled appropriately. The principal may be suffering from cognitive decline and may not understand what is happening.

This creates the perfect environment for abuse.

The person with the power of attorney may be the only person who knows where the money is going.

It Usually Starts Small

Most financial exploitation does not begin with a large theft.

Instead, it often starts with a small justification.

An agent pays themselves back for gas money. They reimburse themselves for helping around the house. They borrow money intending to pay it back later.

Over time, the boundaries begin to blur.

The agent starts viewing the principal's money as their own.

A few hundred dollars becomes a few thousand. A few thousand becomes tens of thousands.

By the time the family discovers the problem, substantial assets may already be gone.

The Most Common Warning Signs

Families often miss the early warning signs because they trust the person holding the power of attorney.

Some common red flags include:

  • Sudden changes in spending patterns.

  • Large cash withdrawals.

  • Missing bank statements.

  • Unexplained gifts.

  • New joint accounts.

  • Changes to beneficiary designations.

  • Transfers of real estate.

  • Refusal to provide financial information.

  • Isolation of the elderly family member.

  • Claims that "Mom wanted me to have it."

While none of these factors automatically indicate wrongdoing, they often appear in cases involving financial exploitation.

The Problem With "Mom Told Me I Could"

One of the most common explanations given by an agent is that the principal verbally approved the transaction.

Unfortunately, these claims can be difficult to verify after someone has died.

The agent may insist that the principal wanted them to have money, a vehicle, or even a house.

Other family members may have never heard such a discussion.

The result is often expensive probate or trust litigation.

Courts are frequently forced to determine whether the transaction was a legitimate gift or an improper use of the power of attorney.

A Power of Attorney Creates Duties

Many people mistakenly believe that holding a power of attorney allows them to do whatever they think is best.

That is not how the law works.

An agent owes fiduciary duties to the principal.

Those duties generally require the agent to:

  • Act in the principal's best interest.

  • Avoid conflicts of interest.

  • Keep accurate records.

  • Preserve the principal's property.

  • Follow the principal's instructions.

  • Avoid self-dealing unless specifically authorized.

The money belongs to the principal—not the agent.

The house belongs to the principal—not the agent.

The authority belongs to the principal—not the agent.

A power of attorney is not a gift. It is a responsibility.

Prevention Is Better Than Litigation

The best time to prevent abuse is before it occurs.

When choosing an agent, ask yourself a simple question:

"Would I trust this person with my entire life savings if nobody was watching?"

If the answer is anything other than an immediate yes, you may want to reconsider.

Other safeguards may include:

  • Requiring accountings.

  • Naming co-agents.

  • Limiting gifting authority.

  • Providing copies to trusted family members.

  • Reviewing financial records regularly.

  • Choosing a professional fiduciary when appropriate.

The right person can be an invaluable help during a difficult time. The wrong person can create damage that may never be fully repaired.

Final Thoughts

Most agents under powers of attorney act honorably and faithfully carry out their responsibilities. They help aging parents, pay bills, manage finances, and provide tremendous support during challenging times.

However, the document itself grants extraordinary power with remarkably little oversight.

That is why powers of attorney are involved in so many financial exploitation cases. The document opens doors that would otherwise remain closed.

Before signing a power of attorney, spend as much time choosing the right agent as you do preparing the document itself. The most carefully drafted power of attorney in the world cannot protect you from the wrong person holding it.

A power of attorney is not inherently a license to steal. But in the wrong hands, it can become one.
