Illinois boat — quick answer
Use this template to record the buyer, seller, price and identifying details for a boat in Illinois. Check the item's title status and the current item-specific agency instructions. A bill of sale alone may not be enough to transfer ownership or register the item.
Is a boat bill of sale required in Illinois?
Check the current Illinois requirements for this item and whether it has a title. An ordinary bill of sale is a record of the agreement, not a replacement for missing ownership documents.
Does a Illinois boat bill of sale need to be notarized?
Check the instructions for the specific title and bill-of-sale form. A requirement to notarize a title assignment does not automatically mean the separate bill of sale needs notarization. If notarization is required, wait to sign until the notary instructs you.

Illinois Boat Bill of Sale — FAQ
Is a boat bill of sale required in Illinois?
Requirements depend on the item and title status. Check the current Illinois instructions for this type of sale; the general motor-vehicle rule may not apply.
Does a Illinois boat bill of sale need to be notarized?
Check the signing requirements for the specific title and bill-of-sale form. Notarization of a title assignment and notarization of a bill of sale are separate questions; a car rule does not establish the rule for this item.
What is a HIN on a boat bill of sale?
The Hull Identification Number is a 12-character code unique to the boat, similar to a VIN on a car. It is required to register the vessel and should be copied exactly.
Do I need a separate bill of sale for the boat trailer and motor?
The motor is usually described on the boat bill of sale. A trailer often has its own VIN and may need its own bill of sale and registration — use our trailer bill of sale for that.
Is a bill of sale proof of ownership?
Generally no. For titled property like a car or boat, the title is what proves ownership. A bill of sale proves that a sale happened and records the price, date, and terms — it supports the title transfer but does not replace it. For untitled property (furniture, equipment, electronics), the signed bill of sale is usually the main proof of ownership.
