How long does a personal injury case actually take?

Average time to settle personal injury claim

Median time from accident to settlement, when no lawsuit is filed: 11.4 months (Martindale-Nolo claimant survey, 2020). When a lawsuit is filed, the median jumps to 21.4 months. About 95% of personal injury cases settle without a trial, per ABA practice surveys.

The five stages

Every personal injury case moves through five stages in roughly the same order.

Stage 1 — Investigation and treatment (weeks 1–8)

You report the accident, get medical care, and start documenting everything. If you've hired an attorney, they're collecting the police report, witness statements, and a complete medical history. If you're handling it yourself, this is the time to start a recovery journal: dates, symptoms, missed activities, sleep impact. Defense will ask for it later anyway.

Stage 2 — Reaching maximum medical improvement (months 2–18)

MMI is the point your treating physician confirms you're as recovered as you're going to get. This stage controls the entire timeline. Settling before MMI means signing a release for injuries you can't yet assess. Most attorneys won't issue a demand letter until you've hit MMI or have a clear medical opinion on what permanent impact remains.

Stage 3 — Demand and pre-suit negotiation (months 6–14)

Your attorney sends a demand package to the at-fault carrier: every medical bill, lost-wage documentation, photographs, the police report, and the proposed settlement number. The carrier has 30 days to respond, though 90 days is more typical. Negotiation runs in 2–5 rounds. Most cases that settle do so here.

Stage 4 — Filing suit and discovery (months 12–30)

If pre-suit negotiation fails, the attorney files a complaint. Discovery begins: written interrogatories (~30 days to respond), document requests, depositions of the parties and witnesses, and the defense's independent medical examination (IME). This phase takes 6–18 months. Most cases settle during discovery as the defense learns what the actual exposure looks like.

Stage 5 — Mediation or trial (months 18–36)

Mediation is mandatory in most jurisdictions before trial. A neutral mediator shuttles between the parties for one day, sometimes two. Roughly two-thirds of cases reaching mediation settle there. Cases that don't proceed to trial, where the median filing-to-verdict time is 25.6 months. Appeals add another 6–18 months if a party files them.

MMI controls everything

Maximum medical improvement is the most important word in personal injury timing. It's the medical concept of "you are as recovered as you're going to get for this injury." Once your physician declares MMI, the future medical bills become predictable, the permanent impairment is documented, and the case can finally be valued.

Typical times to MMI by injury type:

Discovery — the longest phase

If pre-suit negotiation fails and a lawsuit is filed, discovery is where most of the time goes. It's also where most of the case value gets fought over — what comes out in depositions and IMEs reshapes settlement numbers far more than the demand letter did.

Discovery includes:

• Written interrogatories — typically 30 questions from each side, answered under oath. ~30 days to respond.
• Document requests — medical records, employment records, prior insurance claims, social media history (yes, really), tax returns if loss of earning capacity is claimed.
• Depositions — sworn testimony in front of a court reporter. The plaintiff gets deposed. Treating physicians get deposed if their testimony will be needed at trial. Defense experts get deposed. Each deposition takes 2–8 hours.
• Independent medical examination (IME) — defense hires their own doctor to examine you. Their report becomes evidence. This is adversarial; the IME doctor's job is to find reasons your claim is exaggerated.
• Expert reports — life-care planner (for serious injuries), economist (for loss of earning capacity), accident reconstruction (for disputed liability).

Discovery typically runs 6–12 months in straightforward cases and 12–18 months in complex ones. Cases with multiple defendants, extensive medical history, or disputed liability run to the high end.

Why insurers delay (and what to do about it)

Insurance companies have a structural advantage on time. They have unlimited cash flow, no immediate need for the money, and an explicit incentive to delay — every month that passes is a month they earn interest on the reserves set aside for your case. You don't have those advantages.

Common delay tactics:

• Requesting documents you've already provided. The bet: you'll get frustrated and accept a lower number to end it.
• Lowballing the first offer aggressively. Adjusters often open at 35–55% of what the claim is actually worth. The bet: you need money this month.
• Stretching the response window. Most demand letters give 30 days. Adjusters respond on day 28–30 with a counter that triggers another 30-day cycle. Six rounds of this is six months of nothing.
• Demanding more medical records mid-negotiation. Often a stalling move, especially if you've already provided complete records.
• Switching adjusters mid-case. The new adjuster needs time to "get up to speed." Add weeks.

The counter-tactics:

• Document every communication in writing. Send everything in writing yourself.
• Set short deadlines (10 business days) and follow up promptly.
• If the case is approaching the statute of limitations and the carrier won't move, file the lawsuit. Settlement talks continue after filing; the deadline just stops running.
• If you don't have an attorney and the case is significant, hire one. The 3.5× representation premium accounts for the contingency fee with room to spare in most cases above $10,000.

The statute of limitations is a hard wall

State law sets a deadline to file the lawsuit. Miss it and the case is barred, with no exceptions in most jurisdictions. Typical statutes:

The clock starts on the date of injury, with limited exceptions: minors get the clock paused until they turn 18 in most states; "discovery rule" exceptions apply when the injury wasn't reasonably knowable at the time (typically medical-device or toxic-exposure cases). For the standard motor vehicle accident, the deadline is unforgiving.

How to speed it up (without losing value)

Most ways to accelerate a personal injury case cost money — either in the form of a lower settlement or in increased risk. A few don't.

• Document compulsively from day one. Recovery journal, photos of injuries weekly, copies of every bill. Files that arrive complete on day one don't generate the "we need more records" delay.
• Stay current with treatment. Gaps in treatment longer than 30 days kill momentum. The defense argues the gap means you weren't really hurt.
• Don't talk to the other side's insurer. Every conversation creates new evidence to use against you. Refer them to your carrier or attorney.
• Send a complete demand package. If you skip a step (lost wages documentation, future medical estimate, photographs), the carrier uses that as the reason for delay.
• Set firm deadlines. 30 days for a response. 10 business days on minor follow-ups. Follow up the day after a deadline passes.
• Be willing to file the lawsuit. Carriers move faster when they see the case is going to actually be litigated. The threat of filing is more useful than the act of filing in most negotiations.

The non-acceleration most people overlook: don't pressure yourself to settle before MMI. The time savings (a few months) almost never offsets the value lost when late-onset symptoms appear after you've signed the release.
