How to Register a Boat in South Carolina

Overview: Who Needs to Register?

South Carolina requires all motorized watercraft to be both titled and registered through the South Carolina Department of Natural Resources (SCDNR). This applies whether you're buying from a dealer, a private seller, or bringing a boat in from another state.

Non-motorized boats — kayaks, canoes, paddleboards, rowboats — are exempt. No registration, no title, no fees.

You have 30 days from the date of purchase to file your paperwork. After that, late fees kick in.

What You'll Need (Documents Checklist)

The exact documents depend on your situation. Here's a breakdown by scenario. Not sure which applies? See our complete forms guide for detailed checklists.

Buying from a Private Seller (In-State, SC Title Exists)

• Completed BTR-1 form, signed in Section F by all applicants

The BTR-1 Form Explained

The BTR-1 (Watercraft/Outboard Motor Application) is the single form used for all boat titling and registration in South Carolina. It's a multi-section PDF with over 200 fields covering:

• Section A: Buyer/applicant information
• Section B: Seller information
• Section C: Vessel details (make, model, year, HIN)
• Section D: Outboard motor details
• Section E: Lien holder information
• Section F: Registration and buyer signature
• Section H: Built-in bill of sale (requires notarization)
• Section I: Family transfer exemption

Step-by-Step Registration Process

1. Gather your documents. Collect the current title (or bill of sale), proof of ownership, and your county property tax receipt. The checklist above tells you exactly what you need.
2. Fill out the BTR-1 form. Complete all applicable sections: applicant info, vessel description, seller info, and bill of sale. This is where BoatForms saves you the most time.
3. Get the bill of sale notarized. Section H of the BTR-1 must be signed before a notary public. Both buyer and seller should be present. Banks, UPS stores, and courthouses typically offer notary services.
4. Calculate your fees. Add up registration, title, excise tax, and any late fees. See our complete fee breakdown with real examples. Make your check or money order payable to SCDNR.
5. Submit your paperwork. Mail everything to SCDNR or visit one of three office locations in person.
6. Receive your title and registration. Processing typically takes a few weeks by mail. You'll receive your new SC title and registration card.

Where to Submit Your Paperwork

Timeline: How Long Does It Take?

Incomplete paperwork is the #1 reason for delays. Missing signatures, wrong fee amounts, or forgetting the property tax receipt will get your application sent back — and you'll have to start over.

Common Mistakes That Slow You Down

• Missing signatures. All applicants must sign Section F. If the title says "and" — every owner must sign.
• Forgetting the notary. The bill of sale section requires notarization. No notary stamp = returned paperwork.
• Wrong fee amount. Underpaying or forgetting the excise tax delays processing. Use our fee calculator guide to get it right.
• No property tax receipt. You need a paid property tax receipt from your county — or a notice that no taxes are due.
• Altered titles. Any alterations on the title invalidate it. You'll need a duplicate title ($5) and a notarized bill of sale.
• Filing late. You have 30 days from the purchase date. After that, penalties of $15 or $30 apply.
• Missing HIN tracing. Out-of-state boats require a pencil tracing or photograph of the hull identification number. Easy to forget, guaranteed to delay your filing.
