A power of attorney does not override a will. The two documents work in different time periods: a power of attorney gives someone authority to act for you while you are alive, and a will only takes effect after you die. At the moment of death, your agent’s authority ends automatically and your will takes over, so there is never a point when one document can trump the other.
Why One Cannot Override the Other
Think of it as a handoff, not a contest. Your power of attorney is active only while you are living. Your will is dormant until you die. There is no overlap, so there is no opportunity for the agent’s authority to reach into what the will controls.
This also means your agent cannot use a power of attorney to create, change, or revoke your will. Writing a will is treated as a deeply personal act that cannot be delegated to anyone else. Even the broadest financial power of attorney does not give your agent the right to decide who inherits your house or your savings. If you want your will changed, you have to do it yourself while you still have the mental capacity to do so.
The agent also owes you a fiduciary duty while the power of attorney is in force. They must act in your best interest, not their own, and manage your affairs with reasonable care. An agent who uses your accounts for personal benefit or makes reckless decisions has breached that duty and can be held personally liable for the losses.
How an Agent Can Still Shrink What Your Will Delivers
Here is where the practical worry usually lives. An agent cannot rewrite your will, but they can legitimately spend the assets your will promises to other people. That is not abuse; it is the agent doing the job.
Suppose your will leaves a vintage car to your nephew. Then you need expensive long-term care and do not have enough cash to cover it. Your agent, acting under a financial power of attorney, can sell the car to pay your medical bills. The agent’s duty is to take care of you, the living person, not to preserve an inheritance. When you die, the car is gone, and your nephew receives nothing under that gift. The will was not overridden. The asset simply no longer exists.
This creates real tension when the agent and the beneficiaries are different people. An adult child serving as agent may deplete savings that siblings expected to inherit. As long as the spending genuinely serves the principal’s needs, it is legally proper. But it can feel to beneficiaries as though the power of attorney gutted the will.
Assets That Neither Document Controls
Some property never passes through either a power of attorney or a will. These are non-probate assets, and they transfer directly to a named beneficiary at death regardless of what your will says.1Legal Information Institute. Nonprobate Transfer Common examples:
- Retirement accounts such as 401(k)s, IRAs, and pensions pass to whoever is listed on the beneficiary designation form.
- Life insurance proceeds go to the named beneficiary on the policy.
- Payable-on-death bank accounts transfer automatically to the designated person.
- Brokerage accounts with a transfer-on-death registration pass directly to the named beneficiary.
- Property owned as joint tenants with right of survivorship goes to the surviving owner.
- Property held in a revocable living trust passes according to the trust’s terms.
This catches many people off guard. You could draft a careful will leaving your retirement savings to your children, but if your ex-spouse is still listed as the beneficiary on the account, the money goes to your ex. The beneficiary designation form wins every time. Reviewing those forms is one of the most overlooked steps in estate planning.
The Gap Between Death and Executor Appointment
When someone dies, there is a brief window where nobody has clear authority. The agent’s power of attorney expired at the moment of death. The executor named in the will has not been formally appointed yet, because probate has not started. Banks generally freeze the deceased person’s accounts once they learn of the death, and the former agent has no right to withdraw funds or manage property during this window.
Anyone who uses a power of attorney to access accounts after the principal has died is acting without legal authority. It does not matter that they were legitimately authorized the day before. Once the principal is gone, any transaction under that power of attorney is improper and can be treated as financial abuse.
Until the court grants authority to the executor (often through what are called “letters testamentary”), the estate sits in a holding pattern.2American Bar Association. The Probate Process A nominated executor can generally take steps to preserve the estate, such as securing property and preventing waste, but cannot distribute assets or make significant financial decisions until the court officially authorizes them.
When the Agent and Executor Are Different People
Plenty of families name one person as agent under a power of attorney and a different person as executor of the will. On paper this works fine, because the two roles never operate at the same time. In practice, friction is common.
The executor inherits whatever estate the agent left behind. If the agent spent heavily during the principal’s final years, the executor may wonder whether those expenditures were legitimate or whether the agent was benefiting personally. The executor has the right to review the agent’s financial records and, if something looks wrong, to pursue legal action against the former agent on behalf of the estate. Beneficiaries who feel shortchanged can also petition a court to demand an accounting.
Choosing your agent and executor carefully, and being transparent about what you expect from each, is the most effective way to avoid these disputes. Some people name the same person for both roles to keep things simple. Others separate the roles intentionally as a check on power. Either approach can work.
Signs of Agent Abuse and What to Do
An agent with broad financial authority and a vulnerable principal is a setup for abuse if the wrong person holds the role. Common warning signs include unexplained withdrawals, sudden changes to account ownership, and an agent who isolates the principal from family and advisors.
If you suspect abuse, several options exist:
- Revoke the power of attorney. If the principal still has mental capacity, they can revoke the document at any time by putting the revocation in writing and notifying the agent and any institutions holding a copy.
- Petition the court. Family members or other interested parties can ask a court to review the agent’s actions, demand a full accounting, or remove the agent entirely.
- File a civil lawsuit. An agent who breaches their fiduciary duty can be held personally liable for losses the principal suffered.
- Report to law enforcement. In serious cases involving theft or fraud, criminal charges may be brought against the agent.
Prevention beats remedies. When setting up a power of attorney, consider requiring the agent to keep detailed records, naming a second person to monitor activity, or limiting the agent’s authority to specific tasks rather than granting blanket control over all financial affairs. The fiduciary duty owed by an agent is meant to be a real check, but it works best when the paperwork gives someone a straightforward way to verify what the agent is doing.3National Academy of Elder Law Attorneys.

Having a Power of Attorney but No Will
A power of attorney does nothing for you after death, so having one without a will leaves a serious gap. If you die without a valid will, your state’s intestacy laws decide who inherits your property. Those laws follow a rigid formula based on family relationships, usually prioritizing a surviving spouse and children, then parents, then siblings. Your wishes and your relationships do not factor in.
Intestacy laws also do not account for non-family members. A longtime partner, a close friend, or a stepchild you raised may receive nothing. The court will appoint an administrator, and that person may not be someone you would have chosen. A power of attorney handles your lifetime needs. A will handles everything after. You need both for the plan to hold together.
