A Power of Attorney is powerful, so the law allows it to be challenged when something isn’t right. Whether you’re defending a valid document or worried about one that’s being misused, it helps to know the grounds.
Common grounds for a challenge
- Lack of capacity. The principal must have understood what they were signing at the time. If they were already too impaired, the document can be attacked as invalid.
- Undue influence or coercion. If someone pressured or manipulated the principal into signing — or into naming a particular agent — that can void it.
- Fraud or forgery. A signature that was faked, or a document the principal was tricked into signing, is not valid.
- Improper execution. If the signing skipped a required notary or witnesses, the document may fail. See does a Power of Attorney need witnesses.
- Agent misconduct. Even a valid document can be challenged by asking a court to remove an agent who is abusing their authority or self-dealing.
Who can raise it
Typically an interested party — the principal (if able), family members, a successor agent, or sometimes a financial institution or adult protective services — can raise concerns. Where an agent is being removed for misconduct, a court gets involved.
What this means for you as an agent
The best protection against a challenge is doing the role right: act only in the principal’s interest, stay inside the document, keep the money separate, and keep records of everything. Clean records answer almost every question before it becomes a dispute. See recordkeeping for a Power of Attorney.
If you suspect abuse
If you believe someone is misusing a Power of Attorney over a vulnerable person, learn the red flags of financial abuse and don’t wait to raise it. Protecting the principal is the entire point of the role.
