Paperwork for Selling a Boat: Bill of Sale to Title
The handshake is the easy part. What actually transfers a boat from you to the buyer is paper: a boat bill of sale, a title or registration transfer, and — depending on the boat — a lien release, a trailer title, and federal documentation forms. Get these right and the sale is clean; get them wrong and you can stay legally tied to a boat you no longer own.
The Boat Bill of Sale
The bill of sale is the core document of every private boat sale. It records that ownership changed hands, when, between whom, and for how much. A solid one includes:
- Full legal names and addresses of buyer and seller
- Boat year, make, and model
- Hull Identification Number (HIN) — copy it character-for-character from the transom; our HIN guide shows where to find it and how to read it
- Engine make, model, and serial number(s)
- Trailer description and VIN, if included
- Sale price and date
- An "as-is, where-is" clause stating the boat is sold without warranty
- Signatures of both parties
Some states require a notarized bill of sale or their own official form to register the boat — that's a common pattern, not a universal rule, so check your state's boating agency (usually the DMV, DNR, or fish and wildlife department) before closing day. Print two copies and both of you keep a signed original.
Even where a bill of sale isn't strictly required, write one anyway. It's your proof of the sale date and price if a tax question, ticket, or liability claim surfaces later.
Title Transfer
Many states title boats the way they title cars: you sign the title over to the buyer, they take it to the state to register in their name. Other states don't title boats at all — or only title boats above a certain length or with motors — and the registration card plus bill of sale does the job instead. Which camp your state falls in, and where the cutoffs sit, is exactly the kind of detail to confirm with your state agency before the buyer is standing in your driveway.
Practical points that trip sellers up:
- Lost title? Order a duplicate from the state before listing the boat. It can take weeks, and serious buyers walk away from "title is coming."
- Names must match. If the title shows a co-owner or a previous name, resolve it first.
- Fill in the buyer's details completely — a title signed by you but blank on the buyer side ("open title") can leave you on the hook for whatever happens next.
Registration and Notifying the State
The buyer will register the boat in their own state. Your job as the seller, in many states, is to notify the agency that you've sold it — often via a form or online report — which cuts off your liability for the boat's registration, taxes, and anything the new owner does with it. Then remove or cancel anything tied to you. For the full picture of how state systems work, see Boat Registration: How It Works in Every State.
USCG-Documented Boats
If your boat is federally documented with the Coast Guard instead of (or alongside) state registration — common on larger cruisers and yachts — the transfer runs through the National Vessel Documentation Center, and the paperwork is different: a bill of sale on the Coast Guard's form, satisfaction of any preferred ship's mortgage, and the buyer's application to document in their name. Buyers of documented vessels often use a documentation service or close through a broker precisely because this process is unforgiving of errors; if that's your situation, weigh the broker route in Selling Privately vs Using a Broker.
Don't Forget the Trailer
In most states the trailer is a separate vehicle with its own title or registration. Sign it over separately, list it on the bill of sale with its VIN, and hand over its plate/registration per your state's rules. A surprising number of boat sales close cleanly and then snag weeks later on a trailer title nobody thought about.
Loans and Lien Releases
If there's a loan on the boat, the lender holds the title or a recorded lien, and the buyer can't get clean ownership until it's satisfied. Call your lender for an exact payoff amount and their process for third-party sales. The clean ways to close:
- Meet the buyer at the lender's branch, pay off the loan from the proceeds, and have the lien released the same day
- Use an escrow or documentation service that pays the lender directly and releases funds and title simultaneously — standard practice on larger deals
What not to do: take the buyer's money, promise to pay off the loan later, and mail them the title "when it comes." Buyers who know better will refuse, and they're right to.
Records, Manuals, and the Handover Kit
None of this is legally required, but it closes deals and prevents callbacks: the maintenance log and receipts, engine and electronics manuals, warranty documents (check whether any warranties transfer and how), spare keys, and the safety gear you're including. If you've been gathering these while preparing the boat for sale, the handover kit builds itself. Have it ready before your first inquiry — buyers on Marinuo and everywhere else ask about records early, and when you list your boat a "full service records" line does real work.
A Word on Taxes
Sales or use tax on a boat purchase is generally the buyer's problem, collected when they register in their state. As the seller, your concerns are narrower: report the sale if your state requires it, keep your signed bill of sale as proof of the price, and know that a sale far above what you paid can have income-tax implications worth asking a tax professional about. Rules vary by state — one more reason the bill of sale should state the true price.
FAQ
Does a boat bill of sale need to be notarized?
In some states yes, in many no. Check your state's boating agency before closing; if you're unsure, notarizing costs little and satisfies the stricter states.
What if the boat was never titled in my state?
That may be normal — plenty of states register but don't title boats, or exempt smaller ones. Your registration card plus a complete bill of sale typically documents the sale; the buyer's state will tell them what they need to register it there.
Who pays sales tax on a used boat sale?
The buyer, as a rule, when they register the boat in their state. Sellers don't collect tax in a private sale, but keep your bill of sale — states cross-check reported prices.
Should we use an escrow service?
For higher-value boats, documented vessels, or any deal with a loan payoff on either side, yes — it protects both parties by exchanging funds and title simultaneously. For a modest trailerable boat, an in-person closing at the lender or bank usually suffices.
