Wondering if you have a personal-injury case? This screener walks through the core elements — a deadline that hasn't passed, a real injury, someone else at fault, and evidence to prove it — and shows which look present, partial, or missing. It will never tell you 'yes, you have a case'; that's a legal judgment. It will tell you where you stand and what to check next.
Answer a few questions and see which elements look present, partial, or missing — with deadline-first urgency and tailored next steps. Educational only; not a verdict on your case.

Elements of a claim
You appear to be within the typical filing window, but deadlines vary by state and claim type.
Documented injuries and losses are the foundation of the damages side of a claim.
Clear fault on someone else is a strong foundation for liability.
Some documentation helps; filling the gaps strengthens the claim considerably.
What this means
Of the core elements, 3 look present and the rest need attention. That's a reasonable starting point — but whether it adds up to a viable claim is a legal judgment only a licensed attorney can make.
Suggested next steps
This is an educational self-screen, not legal advice, and it does not tell you whether you have a case — only a licensed attorney can evaluate that. A free consultation is usually the right next step. Calculations run in your browser; nothing is saved.

Most claims turn on four things — and the deadline is the one you can't undo.
A workable claim generally needs a timely filing (within your state's statute of limitations), a real injury and losses, fault on someone else, and evidence to prove liability and damages. The screener checks each and flags where you stand.
The deadline comes first on purpose: it's the only element that can quietly expire. Confirm it before you invest effort anywhere else.
Honest screening points you to a lawyer — it doesn't replace one.
Whether facts add up to a viable claim depends on nuances of law and proof that a self-screen can't resolve. Any tool that declares “you have a case” is overstepping. This one is built to inform a conversation with an attorney — most personal-injury consultations are free — not to substitute for it.
The free New Claim Starter Checklist above organizes those first steps — confirming your deadline, preserving evidence, and preparing for a free consultation. Pair it with the relevant free tools and the case-preparation spreadsheet to keep the whole claim file in one place.

No — and it's designed not to. Whether a set of facts adds up to a viable claim is a legal judgment that only a licensed attorney can make. The screener shows which elements of a claim look present, partial, or missing so you can have a more informed conversation.
In general: a timely claim (within the statute of limitations), a real injury and resulting losses, fault on someone else, and evidence to support both liability and damages. Weakness in any one can affect the whole claim.
Because it's the one element you can't fix later. If the statute of limitations has run, even a strong claim is usually barred. That's why the screener checks timing before anything else.
It doesn't necessarily mean you have no claim — facts and law are nuanced. It means that area is worth discussing with an attorney and, where possible, shoring up (for example, preserving evidence or confirming your exact deadline).
This screener is an educational self-assessment only. It does not tell you whether you have a case, does not constitute legal advice, and does not create an attorney-client relationship. Only a licensed attorney can evaluate a claim. If a deadline may be near or passed, consult an attorney immediately.
