What evidence will I need to make a personal injury claim?

Evidence is essential to support a personal injury claim and seek fair compensation for your pain, suffering and financial losses. This should ideally help prove how you were injured, who was at fault, and the full impact on your work, daily life, and well-being.

Key types of evidence include photographs, medical records, witness statements and copies of financial documents, such as payslips and invoices. Without these, it can be very difficult to prove liability, assess damages and proceed with a claim.

A specialist solicitor can help you gather everything you need to support your claim and build a compelling case on your behalf. Our guide explains everything you should know about the evidence you will need to make a personal injury claim and how you can gather it.

    Proof of injury

    Proving that you sustained an injury is one of the first and most important steps in a personal injury claim. To establish liability and seek compensation, you will need clear evidence showing the nature and severity of your injury, as well as its short and long-term impact on your life.

    The evidence you could use as proof of injury includes:

    Medical documentation is one of the most important forms of evidence. This is usually based on medical records from your GP or hospital, which detail your diagnosis, treatment, and prognosis.

    Your solicitor will also obtain a medical report from an independent medical specialist in the field relevant to your injuries. This will assess the harm you suffered, consider whether it is linked to the defendant’s negligence and outline its long-term impact on your health and life.

    Visual evidence of injuries can be highly persuasive. You should take photographs of visible injuries such as cuts, burns or swelling, immediately after the accident and during recovery. It can also help to photograph any surgical wounds, stitches, or medical aids, such as braces.

    Videos can further support your compensation claim by showing any limitations caused by the injury, such as reduced mobility or difficulty performing everyday tasks.

    A personal injury diary can help demonstrate the ongoing impact of your injuries. This should include notes about your pain and suffering, emotional distress and the impact on your work, hobbies and relationships.

    Accident reports, such as police reports for road traffic accidents and official reports for workplace accidents, will also document the harm you sustained. Creating an official record as soon as possible after the incident helps confirm when and how the injury occurred.

    Proof of negligence

    To have a valid claim against another party, you must be able to prove that they owed you a legal duty of care, which they breached through negligence. Evidence that may help show their actions or omissions caused your injury includes:

    Witnesses can provide independent, first-hand accounts of how an accident occurred. They can corroborate your version of the events and confirm that a hazard was present, warning signs were missing, or the defendant acted carelessly or failed to follow safety procedures.

    These include documents such as police reports, accident book entries, and maintenance logs. They can help prove that an accident occurred, that the defendant was aware of the risk and that they failed to take reasonable steps to prevent harm.

    Photographs and videos provide objective visual proof of the accident scene and any hazards contributing to it, such as potholes or wet floors. They can help establish liability and make it more difficult for the defendant to deny that the dangerous condition existed.

    Such footage can provide clear evidence of how an accident occurred, offering a factual account of events. These can also depict unsafe behaviour from the defendant, such as failing to yield the right of way or aggressive driving.

    Sometimes, expert testimony may be used to clarify complex issues and establish whether the defendant’s actions fell below the required standard of care. This may include testimony from specialists such as medical experts, accident reconstruction experts or safety experts.

    Proof of financial losses and expenses

    To make a claim for compensation, you will also need to provide strong evidence to prove that your accident or injury has caused you financial losses and expenses, such as:

    If you were unable to work during recovery or your earning capacity was affected, you may be able to claim compensation for loss of earnings. The evidence you need includes copies of your payslips, your contract of employment, tax returns or bank statements.

    You can recover the cost of all treatment related to your injury, including prescriptions, medical aids, surgery and rehabilitation. Your solicitor will include these costs in your personal injury claim based on evidence such as medical bills, receipts and invoices.

    If personal items were damaged during the accident, you can claim the costs needed to repair or replace them. The evidence required to include these losses as part of your claim includes photos of the damaged items, quotes for repairs and replacement receipts.

    If you needed help with daily tasks following your accident or long-term care because of a disability, you can also claim these costs, even if provided by loved ones. Supporting evidence includes medical assessments, caring diaries, invoices and expert reports.

    You can also include the cost of reasonable travel expenses in your claim, such as transport to and from medical appointments or treatment sessions. These are based on evidence like bus tickets, fuel receipts, credit card statements and appointment letters to confirm attendance.

    If you lost a loved one because of a fatal accident, you could claim funeral expenses and loss of financial dependency. Your claim should be supported by proof of your relationship with the deceased and by financial documents such as receipts, invoices, and bank statements.

    What should you do if you are involved in an accident?

    There are a few steps you should take if you are involved in an accident. These will help support a claim and strengthen your chances of recovering compensation:

    1. Seek immediate medical attention to have your injuries diagnosed and treated.
    2. Take the contact details of witnesses and anyone involved in the accident.
    3. Report the accident to the relevant party or authority as soon as possible.
    4. Gather evidence at the scene and of the damages incurred as a result of your accident.
    5. Keep detailed records of your injuries and losses.
    6. Seek legal advice to find out if you can start a personal injury claim and what evidence is needed to strengthen your case.

    To start a claim, the first thing you should do is contact a specialist personal injury solicitor. They will offer you a free case assessment during which they will explain your legal rights and the evidence needed to make a successful personal injury claim.
