Can Boat Captains Marry You? Countries, Rules, and Recognition

A boat captain can marry you, but only if that captain holds a separate officiant credential and the ceremony complies with the marriage laws of whatever jurisdiction governs the ship at the moment of the vows. Commanding a vessel is not, on its own, legal authority to perform a wedding anywhere in the United States, and it hasn’t been for a very long time.

The Captain’s Authority Is a Myth

The image of a ship’s master pronouncing a couple husband and wife on the open sea comes from an era when captains were the sole legal authority on long voyages, recording births, deaths, and everything in between. That authority no longer exists in U.S. law. No federal or state statute gives a ship captain the power to officiate marriages by virtue of a maritime license or rank alone.

The U.S. Navy settled its own position early and has kept it. Navy Regulations direct that a commanding officer “shall not perform a marriage ceremony on board his or her ship or aircraft” outside U.S. territory, except in narrow circumstances requiring both compliance with local law and the presence of a U.S. consular official.¹ Civilian captains are in a similar position: no officiant power unless they go out and get it separately.

Getting it separately means qualifying the way any other officiant does. A captain can be ordained as a minister, commissioned as a notary public where notaries may solemnize marriages, appointed as a justice of the peace, or otherwise authorized under the law that will govern the ceremony. Some captains take online ordination through groups like American Marriage Ministries, but online ordination is not accepted everywhere, and some states impose registration requirements on top. A captain who tells you they’re ordained is telling you something worth verifying against the specific jurisdiction.

Countries That Let Ship Masters Officiate

A small number of countries have passed laws specifically authorizing the master of a ship flying their flag to act as a marriage officer at sea. These are the exceptions that make a captain-officiated wedding possible.

The Bahamas

Under the Bahamas Maritime Marriage Act, enacted in 2011, the Registrar General may license the master of a Bahamian ship to serve as a marriage officer on the high seas, with the second-in-command acting as a provisional marriage officer.² Couples need a Bahamian marriage license, which can be issued the same day or the following day and is valid for 90 days.³ Because so many major cruise ships fly the Bahamian flag, this is the most common route to a legally binding wedding at sea.

Bermuda

The Bermuda Maritime Marriage Act 1999 lets the responsible minister license the master of a Bermuda-registered ship as a marriage officer. Ceremonies require two or more credible witnesses, and the marriage must be recorded in both a Maritime Marriage Log Book and a Register of Maritime Marriages.⁴ Princess Cruises is the best-known example: several of its captains carry Bermuda marriage licenses.

Malta

Malta amended its Marriage Act in 2008 to extend the definition of “Registrar” to include the master of a passenger vessel registered in Malta on which the marriage takes place, letting the captain act as the civil registrar. Malta’s government directs couples planning shipboard ceremonies to contact the Marriage Registry Section for guidance.⁵

Japan

Japanese-flagged ships also allow captains to perform marriages, but both parties must hold valid Japanese passports, which effectively closes this route to foreign nationals.

Where the Ship Is Determines the Law

The legal framework for your wedding depends on where the vessel is when the ceremony happens. Inside a country’s territorial waters or in port, local law applies, exactly as if you were on land. The U.S. territorial sea generally reaches 12 nautical miles from the baseline, with state waters extending three nautical miles under the Submerged Lands Act.⁶ A ceremony in a Florida port is a Florida wedding, and the captain needs whatever credential Florida requires.

Cross into international waters and the ship’s flag state governs instead. A Bahamian-flagged cruise ship on the open ocean is on Bahamian legal ground, which is why the Bahamian Maritime Marriage Act does the work it does. If the flag state has no law authorizing captains to marry couples, there is nothing to build a legal ceremony on, no matter how far out you are.

Legal Ceremony or Symbolic Ceremony

Cruise lines sell wedding packages, and it matters which kind you’re buying. Lines with ships registered in the Bahamas or Bermuda can often provide legally binding ceremonies officiated by the captain under those countries’ maritime marriage laws. Princess Cruises is the clearest example.

Many other onboard weddings are symbolic only. MSC Cruises, for instance, states plainly that its ceremonies “are symbolic only and have no legal or religious binding.” A symbolic ceremony is a beautiful event with no legal effect, and if that’s what you’re buying you’ll need a separate legal ceremony on land, either before or after the cruise.

Packages generally bundle the officiant fee into the price. They tend to run from around $1,500 to over $6,000, and some lines add roughly $500 for a legal ceremony over a symbolic one to cover the extra licensing and paperwork.

What Has to Be in Place

The captain needs a valid marriage officer license from the flag state. A Bahamian-flagged ship requires the Registrar General’s authorization; a Bermuda-flagged ship requires a written license from the responsible minister under the Maritime Marriage Act.²⁴ Captain’s papers alone do not count.

You’ll need to meet the standard marriage requirements of the governing jurisdiction:

A marriage license from the flag state’s civil authority. Bahamian licenses can be issued the same day or the following day and remain valid for 90 days.³
Minimum age. The Bahamas requires both parties to be at least 18. Bermuda requires both to be at least 21.³
Proof that both parties are free to marry. In the Bahamas, anyone over 40 who cannot produce a divorce decree or spouse’s death certificate may face a two-week records search.³
Witnesses. Bermuda requires at least two credible witnesses; fellow passengers or crew can serve.⁴
Government-issued photo identification.

Getting the Marriage Recognized Back Home

American couples generally get the answer they want: a marriage that’s legally valid where performed is typically valid in the United States. The State Department’s Foreign Affairs Manual confirms the rule, while also flagging that marriages performed on the high seas are treated with care because “their validity and recognition depend upon the various requirements of local laws, as construed and interpreted by the courts.” A ceremony that doesn’t conform to the governing jurisdiction’s law is generally voidable and can be declared void by a court.⁷ The State Department suggests contacting the attorney general of the state where you live to confirm what documentation you’ll need for recognition.⁸

USCIS applies the same place-of-celebration rule for immigration purposes. If the marriage was legal where it took place, USCIS will recognize it, provided it also meets U.S. public policy requirements, both parties were present, and the relationship is bona fide rather than a workaround for immigration law.⁹

After the ceremony, the marriage has to be registered with civil authorities. On a Bahamian-flagged ship, the marriage officer sends a Marriage Duplicate Register to the Registry “as soon as possible.”³ Many cruise lines handle this filing for you, but confirm the timeline and get written proof of submission. Without registration, the marriage may not appear in official records, and that creates problems later for taxes, benefits, insurance, and inheritance.

One quirk to know about: the Social Security Administration has flagged Bahamian marriage documents as unreliable for name-change purposes, saying they “have relatively few security features and are easy to forge.” SSA policy is to refuse Bahamian marriage certificates for updating Social Security records and to require non-Bahamian evidence instead, such as a U.S. court order for a name change.¹⁰ If you marry on a Bahamian-flagged ship and plan to change your name, plan on getting supplementary documentation.

Foreign-language marriage documents typically need a certified English translation before U.S. agencies will accept them, running roughly $15 to $30 per page. Some state vital records offices also want foreign documents authenticated or apostilled before filing.

If the Marriage Turns Out to Be Invalid

If the captain wasn’t properly licensed, the ship was in the wrong waters, or some other defect undermines the ceremony, the marriage may be voidable. That doesn’t necessarily leave you empty-handed. Some states recognize a “putative marriage,” which lets a person who believed in good faith that the marriage was valid claim certain spousal rights, including inheritance and Social Security benefits, as long as that belief was genuine and continued until the defect came to light.¹¹

The simpler fix is to marry again on land with a properly licensed officiant. Plenty of couples treat the at-sea ceremony as the emotional event and handle a quiet legal ceremony before or after. Nothing prohibits two weddings, and doing both removes any doubt about whether the marriage will hold.
