Admiralty Court Forms UK: Part 61 Claims Guide

We're not a law firm — we help you find the right legal support. For advice on your situation, speak to a legal adviser or find a solicitor.

Updated June 2026 · England & Wales
If you are involved in a shipping dispute, a salvage claim, a collision at sea, or a disagreement over cargo, your matter is likely to fall within the jurisdiction of the Admiralty Court. This specialist court sits within the King's Bench Division of the High Court in London and handles maritime claims under Part 61 of the Civil Procedure Rules. The forms, procedures and timescales differ from ordinary civil proceedings, and getting the paperwork right matters. On this page I walk through what the Admiralty Court deals with, which forms tend to come up, and how Part 61 shapes the way a claim runs from start to finish. If you have a specific question about a maritime matter, a call with one of our experienced legal advisers can help you think through your next steps.

What this document is

Admiralty law in England and Wales governs disputes connected to ships, the sea, and maritime commerce. That covers a wide spread of issues: collisions between vessels, salvage rewards for those who rescue ships or cargo, limitation of liability claims by shipowners, disputes over charterparties and bills of lading, mortgages over ships, and claims brought against a vessel itself (known as in rem claims).

The Admiralty Court is the specialist forum for these matters and has been for centuries. Procedurally, claims are governed by CPR Part 61 and its accompanying Practice Direction, which sit alongside the wider Civil Procedure Rules. Much of the underlying substantive law comes from the Merchant Shipping Act 1995, along with older statutes and a number of international conventions incorporated into UK law.

Because maritime disputes often involve parties in multiple jurisdictions, vessels that move across borders, and time-sensitive issues such as arrest of a ship, the procedure has features you will not see in ordinary civil litigation.

How to use this document

  1. Identify whether your claim belongs in the Admiralty Court. Not every dispute involving a boat is an Admiralty matter. The court deals with claims such as collisions, salvage, towage, pilotage, mortgages on ships, forfeiture, limitation of liability, and cargo claims against a vessel. Commercial shipping disputes that are purely contractual may sit better in the Commercial Court, so the nature of the claim matters.
  2. Decide between an in rem and in personam claim. An in rem claim is brought against the ship or property itself and may allow you to arrest the vessel as security. An in personam claim is brought against a person or company. The choice affects which claim form you use, the documents required, and the strategic options available, so think it through before issuing.
  3. Prepare and issue the correct claim form. Admiralty claims in rem typically use Form ADM1, while collision claims use Form ADM3 together with a collision statement of case. In personam claims generally use the standard Part 7 form. You file at the Admiralty and Commercial Registry in the Rolls Building in London, and a fee is payable, so check gov.uk for the current amount.
  4. Serve the claim form and manage early steps. Service rules differ depending on whether the claim is in rem or in personam, and whether the defendant is inside or outside the jurisdiction. For in rem claims, service may be effected on the ship itself. Acknowledgement of service, defences and any counterclaim then follow the timetable set out under Part 61 and the wider CPR.
  5. Progress the claim through case management and trial. The Admiralty judge will give directions on disclosure, expert evidence (which is common in collision and salvage cases), witness statements and trial listing. Many cases settle, but those that proceed are tried in London before a specialist judge, sometimes sitting with Nautical Assessors on technical questions of seamanship.

Common questions

Q What is the Admiralty Court and where does it sit?
The Admiralty Court is a specialist court within the King's Bench Division of the High Court that hears maritime claims. It sits in the Rolls Building in London. It handles matters including collisions, salvage, limitation of liability, ship mortgages and cargo disputes. A specialist judge presides, and in technical cases the court may sit with Nautical Assessors who advise on matters of seamanship and navigation.
Q What is the difference between an in rem and in personam claim?
An in rem claim is brought against property, usually a ship, and can allow the claimant to arrest the vessel as security for the claim. An in personam claim is brought against a person or company in the usual way. Admiralty law is distinctive because it allows in rem claims, which give claimants a form of security that is often unavailable in ordinary civil litigation.
Q Which form do I use to start an Admiralty claim?
The main in rem claim form is ADM1. Collision claims generally use ADM3 together with a collision statement of case. In personam claims typically use the standard Part 7 claim form. There are separate forms for limitation claims, caution against arrest, and warrants of arrest. The court office or an experienced legal adviser can help you identify the right starting point based on what you describe.
Q Can I arrest a ship to secure my claim?
In certain in rem claims, yes. Arrest is a powerful remedy that holds the vessel in port until security is provided or the claim is resolved. You apply for a warrant of arrest through the Admiralty and Commercial Registry. Arrest has strict requirements and can expose the claimant to liability if misused, so the decision to arrest is not one to take lightly without proper guidance.
Q What law governs Admiralty claims in the UK?
Procedure is governed by CPR Part 61 and its Practice Direction. The Senior Courts Act 1981 sets out the court's jurisdiction. Substantive law draws heavily on the Merchant Shipping Act 1995, the Marine Insurance Act 1906, and a range of international conventions incorporated into domestic law, including conventions on salvage, collision, and limitation of liability for maritime claims.
Q Are there strict time limits for maritime claims?
Yes, and several are shorter than the standard six years for contract claims. For example, collision claims typically have a two-year limitation period under the Maritime Conventions Act 1911, and cargo claims under the Hague-Visby Rules are often subject to a one-year period. Because time limits in maritime matters can be short and unforgiving, act promptly and take guidance early.
Q Do I need a specialist lawyer for an Admiralty matter?
Admiralty proceedings are technical, and many cases involve international elements, expert evidence, and strategic questions about arrest and security. While you are not required to use a specialist, most parties do because the rules and conventions are unlike general civil litigation. A call with an experienced legal adviser can help you understand the landscape and think through whether specialist representation is the right next step.
