Part ofUK Court & Tribunal Forms
If you have been injured in a public place and want to bring a low value personal injury claim, Form PL1 is the notification document that formally puts the defendant on notice of the claim. It sits within the pre-action protocol that applies to public liability accidents where the value of the claim sits between a lower and upper threshold.
Getting the detail right on this form matters, because what you put here shapes how the defendant and their insurer respond, and influences the timeline that follows. The form asks for a broad range of information covering the claimant, the injury, any medical treatment, rehabilitation, the accident itself, and the basis on which liability is alleged.
This page walks through each section in plain English so you know what to expect before you start completing it.
What this document is
Form PL1 is the claim notification form used to start a low value public liability personal injury claim through the official portal process. It applies to claims where the injury occurred in a public place (so not at work and not arising from a road traffic accident), and where the overall value of the claim falls within the low value range set by the protocol.
Public liability claims typically involve accidents such as a slip or trip on pavements, falls in shops or public buildings, or injuries caused by poorly maintained premises where someone else owed a duty of care. The form is designed to give the defendant, usually through their insurer, all the information needed to investigate what happened and decide whether to admit or dispute liability.
Because completing it accurately sets the tone for everything that follows, many claimants seek help understanding what each section really needs before they submit it. The form is mandatory, meaning every relevant section must be completed before it goes to the defendant.
How to use this document
- Confirm the claim falls within the PL protocol. Before using Form PL1, check that the accident happened in a public place (not at work, not on the road), that the value sits within the low value bracket, and that the limitation period has not expired. If any of these do not apply, a different route may be needed. 2. Gather evidence before you start writing. Collect photographs of the location, any accident book entries, hospital discharge notes, GP records, receipts for expenses, and names of witnesses. Having this material to hand makes the form far easier to complete accurately and reduces the risk of gaps that slow the claim down. 3. Complete each section in full. Work through the claimant details, injury and medical information, rehabilitation, accident description, and liability sections. Be precise with dates, times, and locations, and include a sketch or photograph of the scene where helpful. Vague or incomplete answers tend to trigger questions from the defendant's insurer. 4. Explain clearly why the defendant is responsible. The liability section is where you set out the factual basis for the claim, such as a failure to maintain premises, a failure to warn of a hazard, or a breach of a specific duty. State what the defendant did or failed to do and how that caused the accident. 5. Send the form to the defendant and keep a copy. Once everything is filled in, submit the form through the appropriate route and retain a full copy with any supporting documents. The defendant then has a set period under the protocol to respond on liability, so diary that date carefully.
Common questions
Q What kind of accidents does Form PL1 cover?
Form PL1 covers personal injury claims arising from public liability incidents, which broadly means accidents in public places or on premises where someone else owed a duty of care. Common examples include slips and trips on pavements, falls in shops or restaurants, and injuries from poorly maintained council land. It does not cover road traffic accidents or injuries at work, which have separate protocols and forms.
Q What value of claim is this form for?
Form PL1 is used for low value public liability claims, which sit within a defined bracket between a lower and upper financial threshold set by the Ministry of Justice. Claims below the lower figure tend to go through the small claims route, and claims above the upper figure fall outside the protocol and follow the standard civil procedure rules. Check the current thresholds on gov.uk before starting.
Q Do I have to fill in every section?
Yes. Form PL1 is a mandatory form, which means each section must be completed before it is sent to the defendant. Leaving gaps can cause the defendant's insurer to reject the notification or come back with questions that delay the claim. If a particular field does not apply, explain why in the form rather than leaving it blank.
Q What happens after I send the form?
Once the defendant receives Form PL1, they have a set period under the pre-action protocol to acknowledge it and then respond on liability. They may admit responsibility, dispute it, or ask for more information. If liability is admitted, the claim moves forward to valuing the injury and losses. If it is disputed, the matter may leave the portal and follow a different path.
Q Can I complete Form PL1 without legal help?
You can, and many claimants do, but the form carries weight because what you write shapes how the defendant responds. If the accident or injury is complex, or if liability is likely to be disputed, talking through the facts with an experienced legal adviser before you complete the form can help you think through what to include and how to frame it.
Q What evidence should I attach or refer to?
Photographs of the location and the hazard, any accident book entry, hospital and GP records, witness details, and receipts for out-of-pocket expenses are all useful. A sketch of the scene with measurements can also help explain what happened. Keep original copies safe and only send copies with the form so you retain the originals for any later hearing.
Q How long do I have to bring the claim?
Personal injury claims in England and Wales are generally subject to a limitation period of three years from the date of the accident or the date the injury was discovered, with some exceptions for children and those lacking capacity. Waiting too long can prevent a claim being brought at all, so it is worth acting promptly once you decide to notify the defendant.
