On a cruise ship in 2026, the person who can legally marry you depends on the ship’s registry (flag state) and the cruise line’s specific permits. Contrary to popular myth, most ship captains do not have the universal authority to perform legal weddings. However, captains on ships registered in Bermuda, Malta, or the Bahamas (such as those from Celebrity, Princess, or Royal Caribbean) can often perform legal ceremonies because the laws of those countries grant them that power. If the ship is in port, a local judge or ordained officiant from that destination can come on board to perform the ceremony. Many couples in 2026 choose a "symbolic" ceremony performed by the captain for the experience, having already completed the legal paperwork on land beforehand. It is essential to check if your home country recognizes "at-sea" marriages, as 2026 legal standards vary, particularly regarding the specific coordinates where the ceremony takes place.
