If you're asking what evidence do you need for a personal injury claim in Tennessee, the short answer is: everything that connects your injury to someone else's actions, photos, medical records, witness statements, police reports, and proof of your losses. At Cummings Law Car Accident & Personal Injury Lawyers, we've seen cases rise or fall on how well that evidence is gathered and preserved.
Most claims rest on three evidence pillars:
Photos and video are the fastest way to lock in what happened. Legal guidance now treats mobile phone video and digital photographs of accident scenes and injuries as primary evidence, according to Salter Healy legal guidance on evidence in injury claims.
Shoot more than you think you need:
Witnesses disappear. Get their info at the scene if you can. Collect:
In Tennessee injury claims, police reports document vehicle positions, witness statements taken at the scene, and signs of intoxication or impairment, per Griffith Injury Law guidance on police reports. That report becomes a neutral record both sides rely on.
Keep your own physical evidence too:
Start a claim file the day you're hurt. Legal practitioners advise keeping a symptom journal from day one to build a record that supports your claim, according to Cummings Law guidance on documenting injuries. That journal plus your bills becomes your proof of loss.

Here's what to collect for every medical visit:
Proving negligence in Tennessee means showing four things: duty, breach, causation, and damages, that the other party owed you a duty of care, broke it, and directly caused your injury and losses.
Tennessee follows a modified comparative fault rule, the single biggest factor most people miss. You can only recover if you are less than 50% at fault. At 50% or more, you recover nothing. Below that threshold, your damages are reduced by your share of fault: a jury finding you 20% at fault on $100,000 in damages leaves you with $80,000.
| Evidence | What It Does to Your Fault Share |
|---|---|
| Dashcam or surveillance footage | Shows the other driver's lane position, speed, and signal use in real time, hard for an adjuster to argue around |
| Police report narrative | Captures the responding officer's independent fault assessment, which carries weight with insurers |
| Witness statements | Corroborate that you had the right of way, were not distracted, and reacted reasonably |
| Medical records showing immediate treatment | Undercuts the argument that you were not hurt or that your injury predated the crash |
| Cell phone records | Can rebut a claim that you were on your phone at impact |
| Traffic camera or signal timing data | Establishes who had the green light when witness accounts conflict |
A common pattern in Tennessee cases: the adjuster offers a low settlement early, then argues you were partially at fault to justify it. With footage, a clean police report, and consistent witness accounts, that argument collapses. Without them, the adjuster can shave 20% or 30% off your recovery without proving you did anything wrong.
The statute of limitations is the deadline for filing your lawsuit. In Tennessee, that is generally one year from the date of injury for most personal injury cases. Narrow exceptions exist, claims against a government entity often require written notice much sooner, sometimes within 60 days. Missing that notice can bar the claim entirely even if you are well inside the one-year window.
Digital evidence is the most perishable evidence in a modern injury claim, and most people lose it before they realize it mattered. Unlike a damaged bumper you can photograph weeks later, digital evidence overwrites, auto-deletes, or gets purged on a schedule you do not control.
A common pattern: by the time a client hires a lawyer two or three weeks after a crash, the dashcam footage is gone and the doorbell clip has auto-deleted, often the single most persuasive evidence in a disputed-fault case.
A single cloud folder beats a shoebox of receipts. Create subfolders by category, medical, photos, witnesses, reports, digital, and drop every document in as you get it, so you can produce anything your lawyer or an adjuster asks for in minutes instead of days.
Use this checklist to organize your file. Check off each item as you gather it.
| Evidence Type | Where to Get It | Typical Timing |
|---|---|---|
| Police report | Responding agency | 3-10 days after crash |
| Medical records | Each provider | Request after each visit |
| Witness statements | At the scene | Same day |
| Dashcam footage | Your device or insurer | Within days, before overwrite |
| Security or doorbell footage | Property owner or management | Within 7-30 days, before auto-delete |
| Ride-share GPS records | App account or platform | Request promptly |
| Lost wage proof | Your employer | Within 2 weeks |
| Vehicle event data | Dealer or manufacturer | Before vehicle is repaired or sold |
The biggest claim-killer is delay. Gaps in medical treatment let an adjuster argue you weren't really hurt. Even a two-week gap raises questions.
Other mistakes we see often:
You need medical records and bills, accident or police reports, witness statements, photos and videos of the scene and injuries, and proof of lost income. For a personal injury claim in Tennessee, objective findings like MRI or CT imaging, surgical reports, and specialist evaluations strengthen your case. The Tennessee Department of Treasury requires documentation of all medical bills and treatment notes from a physician for claims against the state. A symptom journal started the day of your injury also helps show how the injury affected you over time.
Tennessee's personal injury statute of limitations sets the deadline for filing your lawsuit. Missing it usually bars your claim, so confirm the exact deadline for your situation with a Tennessee attorney. The clock generally starts on the date of the injury, but exceptions exist, such as when an injury is not discovered right away. Because the rule is strict, contact a lawyer early to preserve evidence and file on time.
Tennessee uses a modified comparative fault rule. You must be less than 50% at fault to recover compensation. If you are found 50% or more at fault, you are barred from recovery. If you are less than 50% at fault, your damages are reduced by your percentage of fault. This makes evidence that clearly establishes the other party's negligence especially important to your claim.
Invisible injuries such as concussions, soft tissue damage, chronic pain, and emotional distress are hard to prove because they may not show up on standard imaging. Build your case with a symptom journal from day one, consistent medical treatment, specialist evaluations, and objective findings like MRI or CT scans when available. Documenting how the injury limits your daily activities, sleep, and work gives the insurer a clearer picture of your damages.
