Can I Sell a Car on Someone’s Behalf? A Comprehensive Guide for 2023

Selling a car on someone’s behalf is a great way to lend a hand. But it’s often that someone who wants to help a friend or family member sell their car doesn’t know where to start. This comprehensive guide uncovers the necessary steps, potential challenges, and alternative options for selling a car on someone’s behalf in 2023.

Selling a Car on Behalf of Another Person: The Basics

Selling a car on behalf of someone else first requires understanding the legal requirements and responsibilities involved to ensure a smooth and successful transaction.

Understanding the Legal Requirements

The legal requirements of selling a car on behalf of another person include obtaining the owner’s consent, having the proper paperwork, and ensuring the title is transferred to the new owner upon sale. The seller must be listed on the car title or have proper legal authority to sell the vehicle.

The seller should also have the required documents, such as the car title and registration, to proceed with the sale.

Responsibilities of the Person Selling the Car

It’s the responsibility of the person selling the car on behalf of another to adhere to all regulations and to act in the owner’s best interests. They must obtain proper authorization through a power of attorney or a signed confirmation letter from the owner.

The seller also needs to gather all pertinent vehicle documents and prepare the vehicle for sale. They need to advertise the vehicle, manage test drives and negotiations, and finalize the sale in a legally compliant process.

Obtaining Permission from the Owner

Obtaining the owner’s permission is legally done by getting written consent or power of attorney. The most effective way of bestowing legal authority to sell a vehicle, however, is having the owner’s signature on the certificate of title.

Written Consent

Written consent from the owner is a straightforward way to obtain authorization to sell their car. However, to be legally binding, a written consent must clearly articulate the purpose and scope of the agreement, identify the owner and the exact rights required, and express the permission agreement in writing to guarantee clarity and enforceability.

There are potential challenges that arise from getting written consent, such as trust issues, legal complexities, and difficulties in securing permission from the owner. Typically, these are solved by obtaining power of attorney, utilizing a third-party service, or using an online car selling platform.

Power of Attorney

Power of attorney grants the seller legal authority to act on the owner’s behalf, providing a more secure option for selling a car for someone else. The legal requirements for obtaining it vary by state, but they generally include written consent from the owner and a notarized document.

Preparing the Vehicle for Sale

To prepare a car for sale and maximize its sale price, the authorized seller must gather all necessary vehicle documents and ensure that it is in proper condition for selling.

Collecting Vehicle Documents

Collecting the necessary documents, such as the car title, registration, and maintenance records, is essential to have a successful car sale on someone’s behalf. A car title is a legal document that serves as proof of vehicle ownership, while the registration displays the vehicle’s license plate number, make, model, and other relevant information.

As mentioned, the seller must obtain written consent from the owner and power of attorney at this step to comply with the legal prerequisites for selling a car on behalf of another person.

Ensuring the Vehicle is Ready for Sale

To guarantee the car is prepared for sale, start by verifying the vehicle’s maintenance records, such as oil changes, tire rotations, and other services. A VIN Check is a helpful tool for getting information from the DMV’s VIN inspection. To make the vehicle more attractive to potential buyers, make it more presentable by cleaning the interior and exterior, checking all lights and signals, and addressing any mechanical issues.

After taking the steps to get the vehicle in its best condition, it’s now time to start selling it.

Navigating the Sales Process

Successfully selling a car on behalf of someone else involves advertising the vehicle, handling test drives and negotiations, and completing the sale.

Advertising the Vehicle

Advertise a vehicle for sale by using online platforms such as CarGurus, Autotrader, and Craigslist. These platforms provide extensive reach, speeding up the process of finding potential buyers. To create an attractive listing, write a detailed advertisement with high-resolution images, and include all necessary information about the vehicle.

Apart from using online platforms, consider using various channels such as local newspapers and social media, too, to ensure the vehicle reaches a broad audience of prospective buyers. Doing so increases its visibility and improves the chances of a successful sale.

Handling Test Drives and Negotiations

Proper handling of test drives and negotiations guarantees that the owner’s interests are prioritized and that the process is conducted equitably and openly. As the seller, you are responsible for ensuring the vehicle and all necessary paperwork are in order. Throughout the process, be prepared to answer any questions the prospective buyer has and maintain open communication with the owner.

Be well-prepared and cognizant of the applicable regulations when conducting test drives and negotiating with potential buyers. Always be forthright and transparent while taking the owner’s best interests into consideration. This will help build trust and facilitate a smooth transaction.

Completing the Sale

To finalize the sale and to avoid any legal issues, the title, bill of sale, and any other state-required documents must be signed correctly and submitted promptly.

Once the paperwork is in order, transfer the payment to the owner using a secure payment platform, such as PayPal or Venmo. By ensuring all necessary paperwork is completed and the payment is securely transferred, you’ll finalize the sale and fulfill your obligations as the person selling the car on the owner’s behalf.

Potential Challenges and Solutions

Some of the challenges when selling a car on behalf of someone else stem from trust issues and legal complications. Proper planning and communication will help you overcome these obstacles and maintain a positive relationship with the owner.

Trust Issues

Trust issues often arise when selling a car for someone else, and they are typically avoided by ensuring legal authorization, preserving trust in the relationship, and addressing estate matters properly.

When selling a car on behalf of another individual, it is essential to solidify legal authority by obtaining an unequivocal written consent or power of attorney that leaves no room for ambiguity. Throughout the process, communicate regularly and be transparent with the owner to alleviate their concerns and keep them updated. Lastly, ensure complete compliance by taking into account all legal considerations and settling any taxes linked to the sale – the owner will appreciate you for it.

Legal Complications

Legal complications often arise if you don’t have the proper paperwork and permissions. At the very least, you need to have the owner’s signature and consent, confirm their signature on the title, and/or obtain proper authorization if selling on behalf of an estate or a deceased person.

To avoid legal problems, fulfill all requirements and seek legal advice if needed. Drafting a contact between the seller and owner helps, in most cases, to ensure that both parties are aware of the terms of the sale and that the agreement is legally binding.

Alternative Options for Selling a Car

Consider alternative options of selling a car if doing it on someone’s behalf seems too complicated. Selling through a dealership consignment or online car selling platforms simplify the process and provide additional support, making it easier for both the owner and the seller.

Dealership Consignment

Dealership consignment is an arrangement in which a car dealership agrees to market and sell a car on behalf of the owner. The dealership will manage all elements of the sale, such as advertising, test drives, and negotiations, while the owner will receive a portion of the sale price. This allows the owner to benefit from the dealership’s expertise and resources while still maintaining control over the sales process.

By consigning with a dealer, you’ll alleviate some of the stress and responsibility involved in selling a car on behalf of someone else. However, it’s important to research and choose a reputable dealership to ensure a successful sale and a positive experience for all parties.

Online Car Selling Platforms

Online car selling platforms simplify the process by purchasing the car directly or assisting with the online sale. These platforms provide various tools and services to facilitate the advertisement of vehicles, manage test drives, and finalize the sale. They also often offer services such as vehicle inspections, financing, and delivery, while some platforms, such as Sell My Car Online, provide even more convenience by providing instant offers for vehicles and handling all post-sale paperwork.

By using online car selling platforms, both the owner and the seller enjoy a more streamlined process. These platforms also provide access to a wider audience of potential buyers, increasing the chances of a successful sale. However, be aware of the risk of fraud when using some of these platforms.


Selling a car on behalf of someone else is easily handled once you understand the legal requirements, responsibilities, and potential challenges involved. Following the steps in this guide, obtaining proper permissions, and considering alternative options if necessary will empower you to sell a car on someone’s behalf successfully and be a huge help to a friend or family member in the process.
