How Long Does a Personal Injury Case Take to Settle?

Your case timeline effectively can’t start until your medical picture is clear, and that means reaching MMI (maximum medical improvement) — the point where your doctor determines your condition has stabilized and further treatment is unlikely to significantly improve it. MMI doesn’t necessarily mean you’re fully healed; it means your prognosis is now predictable enough to put a dollar figure on your damages, including any permanent impairment.

This is the stage people underestimate most. A soft-tissue injury might reach MMI in six to eight weeks. A fracture requiring surgery and physical therapy might take four to six months. A spinal injury, traumatic brain injury, or anything requiring ongoing specialist care can take a year or longer. Settling before MMI is one of the most common — and costly — mistakes an injured person can make, because once you sign a release, you generally can’t go back and ask for more if your condition worsens or requires future treatment you didn’t anticipate.

While you’re healing, your attorney is usually building the case file: accident reports, witness statements, photos, medical records and billing, employment and wage-loss documentation, and — depending on the case type — expert opinions. For a car accident case, that might mean pulling police reports and vehicle damage estimates. For a slip-and-fall claim, it often means preserving surveillance footage and maintenance logs before they’re deleted or lost.

Once you’ve reached MMI and your file is complete, your attorney sends a formal demand letter to the insurance company. This document lays out liability, describes your injuries and treatment, and demands a specific settlement figure supported by your medical bills, lost wages, and pain and suffering. It’s the formal opening move of the negotiation, and the demand letter timeline is one of the most predictable parts of the whole process.

Insurers typically have an internal window — often 30 to 45 days — to send an initial response, whether that’s an acceptance, a counteroffer, or a denial. Some states impose “good faith” response deadlines by statute, while others leave it to industry norms. If the insurer stays quiet past that window, your attorney will usually follow up, and continued silence can itself become leverage later if the case proceeds to a bad-faith argument.

Negotiation is rarely a single back-and-forth. A typical exchange looks like: demand sent → insurer counters low → attorney responds with support for the original figure → insurer raises the offer → repeat. Each round can take one to three weeks depending on how quickly the adjuster is working and how much internal approval their counteroffer needs. Straightforward claims with clear liability might close in a month of negotiation. Claims involving disputed fault, higher policy limits, or multiple insurers can take three to six months of negotiation before either side lands somewhere both can accept — or before it becomes clear that negotiation has stalled and litigation is the only path forward.

Negotiation timing is also affected by claim value: adjusters generally need more layers of internal sign-off to approve a six-figure settlement than a routine four-figure one, which can add real time even when both sides are negotiating in good faith.

If the insurer won’t offer a fair number — or denies liability outright — the next step is filing a formal complaint in civil court. The defendant then typically has around 30 days to file a response. Filing a lawsuit doesn’t mean negotiation is over; in fact, most lawsuits still settle before trial. It simply moves the conversation into a structured legal process with court-imposed deadlines, which can work in your favor by forcing the other side to take the claim more seriously.

Once a lawsuit is underway, discovery is where both sides formally exchange information, and it is consistently the single longest stretch of a litigated personal injury case. Discovery generally includes:

• Interrogatories — written questions each side must answer under oath
• Requests for production — medical records, employment files, photos, expert reports, and other documents
• Depositions — sworn, recorded testimony from you, witnesses, treating physicians, and expert witnesses
• Independent medical examinations — an exam performed by a doctor chosen by the defense

Discovery drags on for a mix of reasons: court calendars are backed up, attorneys on both sides need time to review large volumes of records, expert witnesses have their own scheduling constraints, and disputes over what must be turned over can trigger motions that add weeks or months. It’s tedious, but it’s also where a lot of the leverage for a strong settlement gets built — thorough discovery often uncovers facts that push the other side toward a more realistic number.

Many courts require or strongly encourage mediation before a trial date is even set — a structured negotiation session with a neutral third party that often resolves cases discovery alone couldn’t. If mediation succeeds, the case can close within weeks of that session.

If it doesn’t, the case moves toward trial vs settlement as a live decision point. This is genuinely the fork in the road that most affects your total timeline. The vast majority of personal injury cases — commonly cited around 90–97% — settle before a jury is ever seated, because trial introduces cost, delay, and unpredictability that both sides usually want to avoid. But when a case does go the distance, the wait for an available trial date alone can run from several months to well over a year, depending on the county and court’s docket, and the trial itself adds days or weeks on top of that. Post-trial motions and potential appeals can extend the final resolution even further.
