What you need to register a boat in Louisiana

Louisiana requires you to register any boat with a motor, regardless of size, before you operate it on state waters. You register through your parish (county) clerk of court's office, not through a state agency. The process takes about 15 minutes in person, or you can mail in your documents. Registration costs vary by parish but typically run $25 to $50 for the first registration, with renewal fees lower.

You will need the boat's hull identification number (HIN), proof of ownership, and a completed process form. If you are financing the boat, the lender's name goes on the registration. If someone else owns the boat but you operate it, you still register it in the owner's name.

Key Takeaways

  • Register your boat at your parish clerk of court's office, not at a state office — each parish handles its own registrations.
  • You need the hull identification number (HIN), proof of ownership such as a bill of sale or title, and a completed process form.
  • Registration costs between $25 and $50 depending on your parish, and you renew every one or two years depending on the parish.
  • You can register in person, by mail, or sometimes online through your parish clerk's website — call ahead to confirm what your parish accepts.

Finding your parish clerk of court and their registration hours

Each of Louisiana's 64 parishes runs its own boat registration system. Start by identifying which parish you live in or where you keep the boat. You can search for your parish clerk's office online by typing "[your parish name] Louisiana clerk of court" into a search engine, or call your local courthouse and ask for the marine or vessel registration office.

Many parish clerks now list their boat registration fees and required documents on their websites. Some offices accept walk-in registrations during business hours, while others require an appointment. A few parishes offer online registration through their websites, though most still require you to submit original documents by mail or in person at some point.

Gathering the hull identification number and proof of ownership

The hull identification number (HIN) is a unique 12-character code stamped into the boat's hull, usually on the starboard (right) side near the waterline or on the transom (back). On older boats, it may be in a different location — check your owner's manual or contact the manufacturer if you cannot find it. Write down the exact number as it appears; a single digit wrong will delay your registration.

Proof of ownership means a bill of sale, a manufacturer's certificate of origin, or a previous registration from another state. If you inherited the boat or received it as a gift, bring a bill of sale signed by the previous owner or a notarized gift letter. If the boat is financed, bring the loan agreement showing the lender's name and address — they will be listed as a lienholder on your registration.

Completing the boat registration process

Louisiana uses a standard vessel registration form, though the exact name and format varies slightly by parish. Most parishes call it the "process for Vessel Registration" or "Boat Registration Form." You can read it from your parish clerk's website, pick it up in person, or request it by phone.

Fill in the boat's HIN, the make and model, the year built, the hull material (fiberglass, aluminum, wood), and the motor type and horsepower. You will also enter the owner's name, address, and driver's license number. If the boat has a lienholder, include their name and address. Sign and date the form in front of a notary public — most parish clerk offices have a notary on staff, and you can have the form notarized there for a small fee, usually $5 to $10.

Submitting your registration by mail or in person

If you register in person, bring the completed and notarized process, your proof of ownership, and a photo ID. Bring a checkbook or ask whether the office accepts credit cards or electronic payment. The clerk will issue your registration number and a decal (sticker) on the spot. You must display the decal on the boat's hull.

To register by mail, send the notarized process, a copy of your proof of ownership, and a check or money order for the registration fee to your parish clerk's address. Include a cover letter with your phone number and email so the clerk can contact you if documents are missing. Mail typically takes one to two weeks, plus processing time. Call the clerk's office after two weeks if you have not received your registration and decal.

Understanding renewal and decal requirements

Louisiana boat registrations expire on different dates depending on your parish — some renew annually on December 31, while others use a staggered renewal schedule. Your registration certificate will show the expiration date. You must renew before that date to operate the boat legally.

The registration decal must be displayed on the boat's hull in a visible location. The decal shows your registration number and year. If the decal is damaged, faded, or missing, contact your parish clerk for a replacement. Operating a boat without a current registration or visible decal can result in a fine from Louisiana Wildlife and Fisheries enforcement officers.

What to do if you buy a boat already registered in Louisiana

If you purchase a boat that already has a Louisiana registration, the previous owner must sign a transfer form releasing their interest. You then submit that signed transfer document, your bill of sale, and a new process to your parish clerk. The process is the same as a first registration — you need the HIN, proof of ownership, and a notarized process.

Do not operate the boat under the previous owner's registration. Even if the registration is current, it is not valid once ownership changes. Register it in your name before you take it on the water.

Frequently Asked Questions

Do I need to register a boat with no motor or a very small motor?

Louisiana requires registration for any boat with a motor of any size. Boats powered only by oars, paddles, or sail do not need registration. If you add a motor later, you must register before operating it.

What if I move to a different parish after registering?

You do not have to re-register with your new parish. Your registration remains valid as long as it has not expired. When it comes time to renew, you can renew through your new parish clerk's office or mail the renewal to your original parish — either way works.

Can I register a boat I do not own yet?

No, you must own the boat or have a signed bill of sale before you register. If you are financing the boat, the lender will provide a document showing they have a security interest; bring that along with your proof of ownership.

How long does registration take if I mail it in?

Processing time varies by parish, typically one to three weeks after the clerk receives your documents. Mail delivery adds another week on each end. Call your parish clerk's office to ask their current processing time before you mail your process.

What happens if my registration expires while I am out of state?

You cannot legally operate the boat in Louisiana with an expired registration, even if you were out of state when it expired. Renew before you return, or renew as soon as you get back. You can renew by mail or in person at your parish clerk's office.
