No, you cannot vote for someone else using a power of attorney. No matter how broadly the document is written, a POA does not transfer the right to cast a ballot. Voting is one of a small set of acts U.S. law treats as too personal to delegate, and Arizona’s election code says so directly, requiring anyone who helps a voter mark a ballot to swear “that there is no power of attorney for voting.”1Arizona Legislature. Arizona Revised Statutes 16-547 – Ballot Affidavit; Form
A power of attorney lets an agent step into the principal’s shoes for financial, legal, or medical matters. Those involve property and private affairs. A ballot does not. Casting a vote is an act of civic participation that depends on the voter’s own judgment, and election law treats the decision as inseparable from the person making it. Even a general durable POA granting sweeping authority does not reach the ballot box.
The Criminal Risk of Casting Someone Else’s Ballot
Filling out and submitting a ballot in another person’s name is a crime, and holding a POA gives you no cover. Federal law makes it a felony to vote more than once or to encourage false registration or illegal voting in federal elections, punishable by up to five years in prison and a fine of up to $10,000.2Office of the Law Revision Counsel. 52 USC 10307 – Prohibited Acts Every state also has its own voter fraud statutes, with penalties ranging from misdemeanors to felonies.
This is where families sometimes get into serious trouble. A relative who already manages a parent’s bank accounts and medical decisions assumes the POA covers “everything,” fills out an absentee ballot for a parent who can no longer communicate a preference, and commits a felony. The authority the POA granted never extended to voting, so the document does not protect the agent from prosecution.
What a POA Agent Can Do to Help Someone Vote
You cannot vote for someone. You can help them vote for themselves. A POA agent, family member, or any other trusted person may assist a voter who needs physical help, as long as the voter is the one making every choice.
- Driving the voter to the polling place or helping them inside.
- Reading candidate names and ballot measures aloud so the voter can decide.
- Physically marking the ballot under the voter’s direct instruction when illness or disability prevents them from doing it themselves.
- Helping request, complete, or deliver an absentee ballot within the limits your state allows.
The rule that governs all of this is simple: the voter directs the choices. The helper is hands and feet. Substituting your own preferences, even nudging them, violates election law regardless of what the POA says.
Federal Protection for Voters Who Need Help
Section 208 of the Voting Rights Act gives voters who are blind, have a disability, or cannot read or write the right to receive assistance from a person of their choice. The only people barred from serving as an assistant are the voter’s employer (or the employer’s agent) and an officer or agent of the voter’s union.3Office of the Law Revision Counsel. 52 USC 10508 – Voting Assistance A POA agent who is not the voter’s employer or union representative qualifies. The authority to help comes from election law, not from the POA.
Requesting or Delivering an Absentee Ballot
A few states do recognize POA authority for the paperwork surrounding a ballot, even though the ballot itself must still be marked by the voter. Alaska allows a person designated in a general or special power of attorney to apply for an absentee ballot on the voter’s behalf.4Justia Law. Alaska Statutes Title 15, Chapter 20, Section 15.20.081 Indiana lets a voter’s attorney-in-fact deliver a sealed absentee ballot to the county election board, provided the person delivering it completes an affidavit and attaches a copy of the power of attorney.5Indiana General Assembly. Indiana Code Title 3, Article 11, Chapter 10, Section 3-11-10-24 These are narrow exceptions covering logistics only. Not every state recognizes them, and the procedures vary, so check your state’s specific rules before relying on this.
Cognitive Decline and the Right to Vote
Most people asking this question are caring for someone with dementia or another cognitive condition. The instinct is understandable. If you already handle the bank accounts, handling the ballot feels like the same job. It is not.
A person with diminished cognitive function may still have the legal right to vote. There is no single national standard for the mental capacity required to cast a ballot. Nearly half of states restrict voting only for people formally adjudicated incapacitated by a court, and about thirteen states tie voting restrictions to being placed under guardianship. Ten states impose no competency-based voting restrictions at all.
A medical diagnosis alone does not strip someone of voting rights. In most states, a court must specifically find a person incapacitated before their voting rights are affected. Someone in the early or middle stages of dementia who still understands they are choosing between candidates generally keeps the right to vote, even if they need physical help to do it. If they can express a choice, your job as agent or family member is to help them express it, not to make it for them.
