Personal Injury Evidence Checklist: What to Keep

What evidence should you keep after an injury?

Keep contemporaneous notes, incident reports, scene and injury photos obtained safely, witness contact details, medical records and bills, expense receipts, work-loss records, insurance correspondence, and the original files behind each item. Preserve rather than edit. Do not delay medical care or enter a dangerous area to collect evidence. Consult a licensed attorney promptly because notice and filing deadlines vary by jurisdiction and type of defendant.

If anyone is in immediate danger or needs urgent medical help, call local emergency services. Evidence collection comes after safety and care.

Begin with a dated factual account

Write down when and where the incident occurred, what you directly observed, what happened next, and who was present. Separate observation from assumption. “The floor was wet” records an observation; “the owner had ignored it for hours” requires evidence that may not yet exist.

Preserve the first version. If a later detail becomes clearer, add a dated supplement rather than silently rewriting the original. Do not coach witnesses, coordinate accounts, or fill gaps with guesses.

Preserve photos and files safely

Photograph the broader scene, relevant conditions, visible injuries, damaged property, warning signs, and changing conditions only when it is safe and lawful. Do not cross barriers, enter traffic, climb, handle hazardous material, or return to an unsafe site for a picture.

Keep digital files with their dates and metadata. Save an unedited copy before cropping or annotating a working copy. Record who made each image and what it shows.

Request formal reports and contact details

Record the report number and request route for any police, workplace, transport, property, or incident report. A report can preserve early observations, but it does not automatically decide legal responsibility.

For witnesses, keep names, contact details, and a short note about what each person appeared to observe. Do not pressure someone to provide a statement. A licensed attorney can advise on lawful contact, preservation, and formal evidence rules.

The California Courts personal injury guide gives a California-specific example of evidence categories: scene or injury photos, medical bills or doctor reports, witness statements, and police reports. It also notes that courts control what evidence they may consider.

Build a medical record, not a diagnosis

Keep appointment summaries, test reports provided to you, prescriptions, referrals, bills, receipts, and insurer explanations. Record symptoms in ordinary factual language, including when they began, changed, or affected daily activities. A qualified clinician determines diagnosis and treatment.

Follow clinical advice and attend recommended care based on health needs, not to manufacture a claim record. Do not stop, delay, exaggerate, or request unnecessary care for perceived legal advantage. Ask the provider how to obtain records through its official process.

Track financial effects with source documents

Keep invoices and receipts for medical care, medicines, travel, mobility aids, property repair, replacement services, and other claimed costs. Label what was paid, by whom, and what remains disputed or outstanding.

For work loss, preserve schedules, pay records, employer correspondence, leave records, and any work restrictions provided by a clinician. For self-employment, retain the ordinary business records that existed before and after the incident. Do not create a backdated invoice or reconstruct lost income without identifying the method and source documents.

Save every insurance communication

Keep policy details, claim numbers, adjuster contact information, letters, emails, portal messages, forms, recorded-statement requests, offers, denials, and deadlines stated by an insurer. After a call, note the date, participants, and topics discussed.

Do not assume an insurer's request establishes your legal duty or that its stated deadline is the only deadline. Before signing an authorization, giving a broad recorded statement, or accepting an offer, ask a licensed attorney in the relevant jurisdiction to review the request and its consequences.

Preserve physical items without altering them

Damaged clothing, footwear, equipment, packaging, or products may be relevant. Photograph the item in place if safe, then ask counsel how it should be stored and whether another party must receive notice before inspection or disposal.

Do not repair, clean, test, dismantle, operate, or discard a potentially relevant item without advice. If it is dangerous, leaking, contaminated, energized, sharp, or structurally unstable, restrict access and contact the appropriate emergency service, regulator, property authority, or qualified technical professional.

The Claim Records section focuses on organization, not case value. The companion guide to the personal injury claim process shows where reporting, investigation, negotiation, and litigation may fit. Claims Process covers the surrounding stages.

Do not wait to check deadlines

Limitation periods, pre-suit notices, government-claim rules, insurance notice duties, and evidence-preservation obligations vary. California Courts, for example, says a California injury lawsuit usually has a two-year deadline from injury and warns that a claim involving a government agency can have a shorter deadline. That is a California example, not a rule for another jurisdiction.

Consult a licensed attorney promptly with the complete facts, all possible responsible parties, and every notice received. A checklist preserves information; it cannot determine the deadline or legal claim.
