Vessel Seizure and Forfeiture Under Federal Maritime Law

Under federal maritime law, a vessel can be seized through an in rem lawsuit for unpaid maritime debts or forfeited by the government for customs violations, drug trafficking, or pollution offenses. The ship itself is treated as the defendant, so the case proceeds against the hull whether or not the owner shows up. Article III of the Constitution puts admiralty cases in federal court, and Congress has built out that authority through statutes covering everything from unpaid fuel bills to narcotics interdiction on the high seas.1Constitution Annotated. Article III, Section 2, Clause 1 – Admiralty and Maritime Jurisdiction

Why a Ship Can Be Sued Directly

Most lawsuits name a person or a company. A maritime in rem action names the vessel. The ship is the defendant, and the case moves forward regardless of whether the owner appears. This exists because ships move. An owner who refuses to pay a repair yard in Miami can sail to Honduras tomorrow, but if the law treats the hull itself as responsible, the yard can have the vessel arrested wherever it next ties up and force payment before it leaves again.

The practical consequence is that anyone with a valid claim against a vessel can ask a federal court to physically detain it. The arrest freezes the ship in place and forces the owner to either post security or defend the case. It also pulls other creditors out of the woodwork, so the court can sort out competing claims against the vessel in one proceeding.

Grounds for Seizure

Unpaid Bills for Services and Supplies

The most common trigger is an unpaid bill. Anyone who provides “necessaries” to a vessel on the order of the owner or an authorized representative automatically holds a maritime lien against the ship.2Office of the Law Revision Counsel. 46 USC 31342 – Establishing Maritime Liens Necessaries include fuel, repairs, towage, dock space, and crew supplies. No paperwork is required. The lien exists the moment the service is delivered, and the lienholder can enforce it by filing an in rem action and having the U.S. Marshals arrest the vessel in any U.S. port.

That automatic lien is what keeps maritime credit flowing. A fuel supplier in New Orleans doesn’t need a signed security agreement before pumping diesel; the lien gives the supplier a claim against the hull itself, and the claim follows the ship.

Customs Violations and Smuggling

The federal government can seize any vessel used in customs violations, including smuggling undeclared goods or importing prohibited merchandise.3Office of the Law Revision Counsel. 19 USC 1594 – Seizure of Conveyances There are some protections. A vessel cannot be forfeited for a drug-related offense if the owner proves the violation happened without their knowledge, consent, or willful blindness. Common carriers get an added shield: the vessel isn’t subject to forfeiture for cargo matching the manifest unless the owner or someone in charge actually knew about the violation or was grossly negligent in missing it. When concealed contraband is found on board or cargo doesn’t match the shipping documents, the burden shifts to the owner to prove that no responsible person could have discovered it even with the highest degree of diligence.

Drug Trafficking

Narcotics enforcement drives a large share of government-initiated seizures. Any vessel used to transport or facilitate the sale of controlled substances is subject to forfeiture.4Office of the Law Revision Counsel. 21 USC 881 – Forfeitures The Maritime Drug Law Enforcement Act extends federal jurisdiction to vessels in international waters, so a boat does not need to be anywhere near U.S. territory for the government to act.5Office of the Law Revision Counsel. 46 USC Chapter 705 – Maritime Drug Law Enforcement

The criminal exposure for crew is severe. Prison sentences range from five years to life depending on the substance and quantity. For large-quantity offenses involving drugs like cocaine or heroin, the mandatory minimum is ten years, and repeat offenders face at least fifteen years to life.6Office of the Law Revision Counsel. 21 USC 960 – Prohibited Acts Those penalties come on top of losing the vessel.

Pollution Offenses

Federal authorities can also detain vessels that violate marine pollution laws. Under the Act to Prevent Pollution from Ships, a knowing violation of MARPOL standards is a Class D felony, and the vessel itself is liable in rem for any criminal fine or civil penalty.7Office of the Law Revision Counsel. 33 USC 1908 – Penalties Civil penalties can reach $25,000 per violation, with each day of a continuing violation counted separately. If the government has reasonable cause to believe a ship violated these laws, it can refuse or revoke the vessel’s customs clearance, which effectively traps the ship in port until the owner posts a bond or surety.

What Happens After the Vessel Is Arrested

An in rem case starts with a verified complaint filed under oath. The complaint has to describe the vessel with reasonable particularity and state that the property is physically located within the court’s judicial district.8Legal Information Institute. Supplemental Rules for Admiralty or Maritime Claims – Rule C Vague allegations won’t support a warrant. Once the court is satisfied, it issues a warrant for arrest in rem, and the U.S. Marshals Service takes physical custody. A deputy marshal boards the ship, serves papers on whoever is in charge, and posts a formal notice of arrest on a prominent part of the superstructure. Moving the vessel or interfering with the arrest can bring contempt charges.

If you own a vessel that has just been arrested, the clock starts immediately. Anyone claiming an ownership interest or right of possession has 14 days after the arrest to file a verified statement of interest with the court.8Legal Information Institute. Supplemental Rules for Admiralty or Maritime Claims – Rule C Missing that deadline can result in a default judgment handing the vessel to the plaintiff without a trial. The court can extend the time, but counting on an extension is a gamble.

Notice to the wider world depends on who initiated the seizure. In a civil in rem arrest, if the vessel isn’t released within 14 days, the plaintiff must publish notice in a court-designated newspaper of general circulation in the district.8Legal Information Institute. Supplemental Rules for Admiralty or Maritime Claims – Rule C Government forfeiture actions require publication once a week for three consecutive weeks in a newspaper, or posting on an official government forfeiture website for at least 30 consecutive days.9Legal Information Institute. Supplemental Rules for Admiralty or Maritime Claims – Rule G

The vessel stays in the custody of the Marshals or a court-appointed custodian throughout the litigation. Custody expenses pile up: storage, dockage, insurance, watchmen’s fees, and the hourly cost of any deputy marshals providing security.10Office of the Law Revision Counsel. 28 USC 1921 – United States Marshals Service Fees The Marshals collect a deposit from the plaintiff up front, with additional deposits required as costs accrue. For larger vessels, these costs can climb into the tens of thousands of dollars and eat into whatever is eventually recovered.

How to Get the Vessel Released

Demanding a Prompt Hearing

A vessel owner does not have to accept the arrest. Anyone claiming an interest in the property is entitled to a prompt hearing where the plaintiff must justify why the arrest should remain in place.11Legal Information Institute. Supplemental Rules for Admiralty or Maritime Claims – Rule E The burden sits on the plaintiff. The rules don’t fix a number of days, but the hearing has to happen as quickly as practicable once the owner requests one. One limit: this prompt-hearing right does not apply to forfeiture actions brought by the United States, which follow a separate procedural track.

Posting Security to Free the Ship

The fastest route back into service is to post security that substitutes for the ship. Once adequate security is posted, the Marshals must release the vessel, and the bond or stipulation stands in for the hull as the subject of the lawsuit.11Legal Information Institute. Supplemental Rules for Admiralty or Maritime Claims – Rule E

How the amount gets set depends on whether the parties can agree:

  • Stipulated amount: the plaintiff and the vessel owner agree on a bond covering the claim, interest, and costs. This is the simplest path.
  • Court-fixed amount: if the parties can’t agree, the court sets the bond at an amount sufficient to cover the claim with accrued interest and costs, capped at twice the plaintiff’s claim or the vessel’s appraised value, whichever is less.11Legal Information Institute. Supplemental Rules for Admiralty or Maritime Claims – Rule E
  • Statutory default: if neither the parties nor the court set the amount, the bond defaults to double the amount claimed.12Office of the Law Revision Counsel. 28 USC 2464 – Security, Special Bond

The bond must come from a corporate surety holding a certificate of authority from the Secretary of the Treasury. An owner facing multiple suits against the same vessel can file a general bond covering all pending cases, as long as the secured amount stays at least double the total of all claims. Many owners use a letter of undertaking from their Protection and Indemnity club in place of a formal surety bond, but a plaintiff is entitled to demand a proper surety bond and cannot be forced to accept a club letter.

Defenses When the Government Seeks Forfeiture

Innocent Owner Defense

An owner with no part in the criminal activity isn’t automatically out of luck. Federal law provides an innocent owner defense that applies across most civil forfeiture statutes.13Office of the Law Revision Counsel. 18 USC 983 – General Rules for Civil Forfeiture Proceedings The owner carries the burden by a preponderance of the evidence.

For someone who owned the vessel when the illegal conduct occurred, “innocent owner” means a person who either didn’t know about the conduct or, upon learning of it, did everything reasonably possible to stop it. That can mean notifying law enforcement, revoking permission for the wrongdoer to use the vessel, or taking other reasonable steps. No one is required to take actions they reasonably believe would put someone in physical danger.13Office of the Law Revision Counsel. 18 USC 983 – General Rules for Civil Forfeiture Proceedings For someone who acquired the vessel after the violation, the defense requires showing they were a good-faith purchaser who paid fair value and had no reason to believe the vessel was subject to forfeiture.

Protection for Mortgage Holders

Lenders with a preferred ship mortgage get a separate statutory shield. A mortgagee’s interest can only be terminated through government forfeiture if the mortgagee authorized, consented to, or conspired in the illegal conduct.14Office of the Law Revision Counsel. 46 USC 31327 – Forfeiture of Mortgagee Interest A bank that financed a fishing vessel does not lose its mortgage just because the operator decided to run drugs. If the lender wasn’t part of the scheme, the security interest survives.

Petitioning for Remission or Mitigation

Even when a forfeiture is technically valid, an affected party can petition the seizing agency to return the property or reduce the forfeiture. Petitions for remission or mitigation must be filed within 35 days of receiving the notice of seizure, or within 30 days of the last public posting if notice wasn’t personally received.15eCFR. Seizure and Forfeiture Procedures The petition must include the petitioner’s interest in the property, documentary evidence supporting ownership or lien status, a factual statement explaining why remission is justified, and a sworn declaration that the information is truthful. Filing a false petition carries criminal penalties. If the petitioner also files a formal claim to the property in court, the administrative petition process ends and the matter moves to full judicial proceedings.

If the Vessel Is Sold

When a court orders forfeiture or a sale to satisfy debts, the Marshals conduct a public auction and the proceeds take the place of the ship. There is rarely enough money to pay every claimant, so maritime law uses a fixed hierarchy. Where your claim sits in that hierarchy matters far more than when you filed suit.

From highest to lowest, the general ranking is:

  • Expenses of justice: court costs and expenses incurred during the arrest and sale come off the top.
  • Crew wages: seaman wage liens are treated as the most protected substantive category.
  • Salvage and general average: those who rescued the vessel from peril rank next.
  • Tort claims: personal injury, death, or property damage caused by the vessel.
  • Pre-mortgage necessaries liens: supplies and services provided before a preferred ship mortgage was recorded.
  • Preferred ship mortgages: a preferred mortgage lien has priority over all claims except expenses, costs, and preferred maritime liens.16Office of the Law Revision Counsel. 46 USC 31326 – Court Sales to Enforce Preferred Mortgage Liens
  • Post-mortgage necessaries liens: supplies and services provided after the mortgage was recorded.

Within each class, maritime law follows a “last-in-time, first-in-right” rule. The most recent fuel supplier gets paid before the one from six months ago, because more recent services kept the vessel operational and preserved value for everyone else. Preferred ship mortgages are an exception and follow their own rules. Whatever is left after all valid claims are satisfied goes to the former owner, or to the government in a forfeiture case.

For the buyer, a judicial sale produces one of the cleanest titles in property law. The bill of sale from the U.S. Marshal is free of every prior lien, mortgage, and encumbrance. All previous claims against the vessel are extinguished and transferred to the sale proceeds instead.16Office of the Law Revision Counsel. 46 USC 31326 – Court Sales to Enforce Preferred Mortgage Liens The new owner can register and operate the vessel without worrying about unknown creditors appearing later, which is why seized ships can return to productive service rather than sit idle under a cloud of unresolved claims.
