What Documents You Need to Close a Private Boat Sale

Selling a boat without a broker is legal in every state. What trips people up is the paperwork, and the fact that missing one document can stall a closing for weeks or void the transfer entirely.

The four documents every private boat sale needs

1. Purchase Agreement

This is the contract. It states the price, the deposit amount, who pays what, and, critically, the contingencies. Without a written purchase agreement, a handshake deal gives neither side any recourse when something goes wrong. It should be signed before any money changes hands.

2. Bill of Sale

The bill of sale is the proof of transfer. It names buyer and seller, identifies the vessel by hull identification number, states the purchase price, and is signed at closing. Many states require it to be notarized before the title office will accept it. See what a bill of sale must include to hold up.

3. Title or Documentation

State-titled vessels need the original title, signed over by the seller. Vessels registered with the U.S. Coast Guard need a different set of forms entirely, and the state title process does not apply. Confirm which category your boat falls into before you get to closing, because the paperwork paths do not overlap.

4. Lien Release

If the seller still owes money on the boat, the lender holds a lien. A buyer who closes without a written lien release can end up owning a boat the bank can still repossess. Get the release in writing from the lienholder, not a verbal assurance from the seller.

The documents people forget

Those four are the backbone. But a clean closing usually involves more: a survey contingency addendum if the sale depends on inspection results, a deposit receipt establishing the funds are held and under what conditions they are returned, an as-is acknowledgment, and state-specific tax or registration forms.

Deals rarely fall apart because someone missed the bill of sale. They fall apart because nobody wrote down what happens if the survey turns up a soft transom, and then two people who were friendly in June are arguing about a deposit in July.

Why the order matters

The sequence protects both sides. Purchase agreement first, so the terms are fixed. Deposit into escrow second, so the buyer is committed and the seller stops showing the boat. Survey and contingency period third. Then the bill of sale, title transfer, and release of funds together at closing. More on how deposits and escrow protect both sides.

Sellers who hand over a signed title before funds clear, and buyers who wire money before the lien is released, are the two most common ways a private boat deal turns into a lawsuit. If you are handling the whole sale yourself, start with our step-by-step guide to selling without a broker.
