Yes, you can sell your dad’s car if you have power of attorney, but two conditions have to be true: the document must grant you authority over his personal property or vehicle transactions, and your father must still be alive when the sale happens. A power of attorney dies with the principal, so if he has already passed, the document gives you no authority at all. Assuming he’s living and the POA is properly drafted, the sale comes down to signing the title in a specific format, meeting your state’s DMV requirements, and putting every dollar of the proceeds into his account.
Read the Document Before You Do Anything Else
Not every power of attorney covers vehicle sales. Pull the document and look for language granting you authority over “personal property” or “tangible personal property.” A general power of attorney with that kind of broad grant typically lets you sell, lease, or otherwise dispose of items your father owns, including vehicles. Under the Uniform Power of Attorney Act, which many states have adopted a version of, a grant of general authority over tangible personal property authorizes the agent to sell, exchange, or convey it.
A limited or special power of attorney is narrower. It restricts you to the tasks listed. If the document only mentions managing bank accounts, you cannot sell a car under it. The POA has to reference vehicle transactions, motor vehicle titles, or personal property sales in some form. Read the authority section literally, because courts do.
Durability matters just as much. A durable power of attorney stays effective even if your father becomes mentally incapacitated. A non-durable POA ends the moment he loses capacity. If he can no longer make decisions for himself and the document isn’t durable, you have no authority to act. This is the scenario most families are actually facing when they go looking for answers, and it’s why estate planning attorneys recommend making every POA durable from the start.
If Your Father Has Died, the POA Is Useless
This is the single most common misunderstanding, and acting on it can cause serious legal trouble. The moment your father dies, the power of attorney terminates automatically. It doesn’t matter what the document says, it doesn’t matter that you were properly authorized yesterday, and it doesn’t matter that the DMV hasn’t been notified. Death ends it. Any transaction completed with a POA after the principal’s death is unauthorized and can expose you to civil liability or criminal fraud charges.
Once he’s passed, the vehicle becomes part of his estate. Transferring it requires probate, a court-appointed executor or administrator, or in many states a small estate affidavit for estates below a set dollar threshold. The exact process depends on your state, whether he had a will, and the value of the estate. Your DMV will have a separate procedure for transferring a deceased person’s title, and it will require court documents, not a POA.
How to Sign the Title and Bill of Sale
When you sign the title and bill of sale as an agent, you can’t just write your own name. The signature has to show you’re acting on someone else’s behalf. The standard format is the principal’s full legal name first, then your name followed by “as Attorney-in-Fact” or “as Agent.” A signature line might read: “John Doe, by Jane Doe, Attorney-in-Fact.”
This format puts the buyer and the DMV on notice that the person signing isn’t the titled owner. Sign only your own name and the DMV will reject the transfer. Sign only your father’s name without identifying yourself as agent and you’ve forged his signature. Neither result is easy to clean up, so get the format right the first time.
Documents to Gather Before the Sale
Line everything up before you list the car or meet with a buyer.
- The original POA or a certified copy. Most DMV offices will not accept a regular photocopy. Some states require the POA to be notarized, and a few have their own POA forms specifically for vehicle transactions that must be used alongside or instead of your existing document. Call your local DMV to confirm what they’ll accept.
- The vehicle title. This is the certificate of ownership issued by the state. If your father can’t find it, you can apply for a duplicate at the DMV using your POA authority.
- A bill of sale listing the buyer, the seller, the VIN, the sale price, and the date. You sign it using the agent format above. Some states provide a standard form; others accept any written version.
- An odometer disclosure statement. Federal law requires the seller to disclose mileage in writing at the time of sale. This is often printed on the title itself or on a DMV form.
The odometer requirement has an age exemption. Vehicles with a 2010 or older model year are currently exempt from federal odometer disclosure. Vehicles from 2011 and newer still require disclosure, and that won’t change until January 1, 2031, when 2011 models hit the 20-year exemption threshold under NHTSA regulations.1eCFR. 49 CFR 580.17 If your dad’s car is a 2011 or newer model, fill out the odometer statement accurately. Falsifying mileage is a federal offense under the Motor Vehicle Information and Cost Savings Act.2Office of the Law Revision Counsel. 49 USC 32705 – Disclosure Requirements on Transfer of Motor Vehicles
You Generally Cannot Sell the Car to Yourself
Here’s where people get tripped up. You generally cannot use the POA to sell the car to yourself. That’s self-dealing, and it violates the foundational principle that an agent must act for the principal’s benefit rather than their own. When the same person sits on both sides of a transaction, the conflict is built in. Courts scrutinize these deals heavily, and most states prohibit them unless the POA document contains explicit language authorizing self-dealing.
Some state DMV offices enforce this at the counter. New York’s DMV, for example, will not accept a general POA to transfer a title when the person transferring and the person receiving are the same individual. Even where the DMV doesn’t catch it, another family member or an interested party can challenge the sale in court and have it reversed. If you want to buy your father’s car, the safer path is for him to sell it to you directly while he’s competent, or to get court approval.
Every Dollar Goes to Your Father
The sale proceeds belong to your father. That’s not a gray area. As his agent you owe him a fiduciary duty, which means acting in his interest, keeping his money separate from yours, and accounting for every penny. Deposit the funds directly into his account. Don’t run the money through your own account first, even for a day, because commingling is one of the fastest ways to invite legal scrutiny.
Keep a paper trail: the bill of sale, the deposit receipt, any correspondence with the buyer, and a record of the sale price relative to the car’s fair market value. If a family member or a court ever questions the sale, those records are your defense. Agents who can’t produce documentation tend to lose disputes even when they acted honestly.
Breaching that duty carries real consequences. Depending on the severity, you could face a civil suit for restitution and damages, removal as agent, or criminal charges if the breach involved theft or fraud. Courts ask whether a reasonable person in your position would have done the same thing, and “I didn’t know” is a weak defense when you’re holding someone else’s money.
If There Is a Lien on the Car
If your father still owes money on the car, the lender holds a lien on the title. You cannot transfer a clean title until that lien is satisfied. Call the lender for a payoff amount. In most private sales, the buyer pays the full purchase price, the agent uses those funds to pay off the lender, the lender releases the lien, and then the title transfers.
Some lenders will work with an agent once they see a valid POA. Others require additional documentation or want their own legal department to review first. Build extra time into the transaction for this. If the car is worth less than the balance owed, you’re in a short sale situation, and the lender would need to agree to accept less than the full payoff, which they are under no obligation to do.
Tax Considerations
The tax implications fall on your father, not you, because he’s the owner. For a personal-use vehicle, the math usually works in the seller’s favor. Cars depreciate, so most sell for less than the original purchase price. A loss on a personal vehicle isn’t deductible. If he somehow sells for more than he paid, the profit is taxable as a capital gain.
Watch the sale price. If you sell the car well below fair market value, the IRS may treat the shortfall as a gift from your father to the buyer. The IRS defines a gift as any transfer where full consideration is not received in return.3Internal Revenue Service. Frequently Asked Questions on Gift Taxes For 2026, the annual gift tax exclusion is $19,000 per recipient.4Internal Revenue Service. Whats New – Estate and Gift Tax If the gap between the sale price and fair market value exceeds $19,000, your father, or you on his behalf, would need to file a gift tax return. No tax is necessarily owed at that point since the excess counts against the lifetime estate and gift tax exemption, but the reporting obligation still applies.
