The process begins the day of the accident, whether you are thinking of it that way or not. The decisions made in the first forty-eight hours — whether you sought medical treatment, what you said to the other driver and to the police, whether you documented the scene, what you told the responding officer, whether you contacted an attorney — all become part of the factual record that your case is built on. The insurer for the at-fault driver opens a claim file the day they receive notice, which may be the same day if their insured calls them from the scene. From that moment forward, the adjuster assigned to your claim is building a file that will be used to minimize what they pay you. The sooner you have representation, the sooner someone is building a counter-record on your behalf.

The medical treatment phase is the longest and most consequential portion of the timeline, and it is the phase over which neither your attorney nor the insurance company has meaningful control. It runs from your first post-accident medical visit until the day your treating physician determines that you have reached maximum medical improvement — the point at which your condition has stabilized and further significant recovery is unlikely. For a soft tissue injury that responds well to chiropractic care and physical therapy, this phase might last eight to twelve weeks. For a herniated disc requiring epidural injections and eventual surgical evaluation, it might last eighteen months or more. For a traumatic brain injury with evolving neurological symptoms, the treating physician may not be comfortable declaring MMI for two years or longer. Your attorney cannot send a meaningful demand until this phase is complete, because settling before MMI means accepting a number based on an incomplete medical picture — and once you sign the release, there is no going back for the surgery or the ongoing treatment that was not yet accounted for.

This is the phase that feels like nothing is happening, and it is the phase where the most important work of your case is quietly occurring. Your attorney is gathering records as they are generated, monitoring the treatment, tracking outstanding liens, and building the factual foundation of your case. The insurer, for their part, is doing their own investigation — interviewing witnesses, reviewing the police report, obtaining your prior medical records to look for pre-existing conditions they can use to discount your injury claims, and sometimes placing your claim under surveillance in high-value cases. Neither side is doing nothing. The visible activity is simply at a low level until treatment concludes and the documentation phase begins.

Once you reach maximum medical improvement, the documentation and demand phase begins. Your attorney sends requests for all outstanding medical records and bills from every provider who treated you, requests your employment records and wage documentation if lost income is part of your claim, obtains any expert opinions that may be needed, and assembles everything into a demand package. This phase takes longer than most clients expect — typically four to eight weeks, sometimes longer in complex cases — because medical providers are notoriously slow to respond to records requests and because assembling a complete, accurate, well-organized demand package requires time that cannot be compressed without sacrificing quality. The demand package is the primary document through which your case is communicated to the adjuster. A complete, well-constructed package removes the insurer’s legitimate basis for delay and creates pressure for a timely response. A thin or disorganized package creates gaps the adjuster can exploit to request additional information, which adds weeks at each iteration.

Here is something about this phase that most people in the middle of it do not know: the demand letter your attorney sends is not a starting point from which the parties negotiate toward the middle. It is a ceiling that the insurer will attempt to erode. The demand amount your attorney selects is not arbitrary — it is chosen to give room to negotiate down to a number that represents full compensation for your actual damages while remaining high enough that the final settlement is defensible as fair. An attorney who sends a demand for exactly what they expect to settle for has no room to negotiate and no ability to absorb a counteroffer without immediately compromising their client’s recovery. The space between the demand and the eventual settlement is the negotiating room, and it is built intentionally. Understanding this prevents the disorientation that many clients experience when they learn that the insurer has countered at a fraction of the demand and their attorney does not appear alarmed.

The insurer’s response to the demand typically arrives within thirty to sixty days if the package was complete and liability is clear. The response is almost always a counteroffer below your demand, sometimes dramatically so. What follows is a negotiation that may resolve in one or two exchanges or may require several rounds over weeks or months, depending on how far apart the parties are, how complex the case is, and how motivated the insurer is to avoid litigation. In cases where the gap between the parties is large and pre-litigation negotiation stalls, the next step is filing a lawsuit — not because trial is imminent, but because the litigation process creates the deadline pressure and discovery exposure that produces serious engagement from an insurer who has been treating negotiation as something to manage at their own pace.

Litigation adds time. This is the part of the timeline that surprises people who think of filing suit as a way to accelerate resolution. It is, but it accelerates the back half of the process by creating pressure, not by shortening the overall calendar. Once a lawsuit is filed, the court assigns a scheduling order with discovery deadlines, deposition cutoffs, and a trial date — typically twelve to eighteen months from filing in most jurisdictions, sometimes longer in busy urban courts. The vast majority of cases filed never reach trial. Most settle during the discovery period, when both sides have seen each other’s evidence, deposed the key witnesses, and developed a realistic assessment of what a jury is likely to do. Cases that seemed far apart on value in pre-litigation negotiation often converge during the litigation phase because the information gathered through discovery changes each side’s assessment of the risk they face at trial. The trial date functions as a forcing mechanism — cases settle on the courthouse steps far more often than they actually go to verdict.

Mediation typically occurs in the late stages of litigation, after discovery is largely complete and both sides have a realistic sense of their positions. A mediator — usually a retired judge or experienced attorney selected by both parties — spends a day or a half-day moving between the parties’ rooms, probing the weaknesses in each side’s position and searching for the number where a deal can be done. Most cases that enter mediation settle there. Not because either side gets what they wanted, but because the mediator’s role is specifically to find the zone of agreement between what the plaintiff will accept and what the defendant will pay, and to make accepting a number in that zone feel more rational than the continued uncertainty and expense of trial. Mediation is not a sign that the case has broken down. In most personal injury cases it is the designed resolution mechanism, and going into it with realistic expectations about what your case is worth — based on your attorney’s actual trial experience with similar cases in front of similar juries — is the most important preparation you can do.

After a settlement is reached, whether in pre-litigation negotiation, at mediation, or after a verdict, the closing process takes time that most people are not prepared for. A settlement agreement must be drafted and signed. The insurer must issue a settlement check, which typically takes two to four weeks after the agreement is executed. The check is sent to your attorney, who deposits it into a trust account and holds it for the bank clearance period. During that period your attorney prepares a settlement statement accounting for every dollar — attorney fees, all outstanding liens, any subrogation claims from your health insurer or MedPay carrier, case costs advanced during litigation — and both you and your attorney sign off on it before the net proceeds are released to you. In cases with significant medical liens, the lien negotiation that happens during this closing period can add weeks or months, because your attorney is negotiating with each lienholder to reduce their claim and maximize what reaches you. The signed settlement agreement is not the end. It is the beginning of a closing process that takes most people by surprise because no one warned them it was coming.

The single most useful thing you can do with a timeline is compare it honestly against where your case actually is. If you are in the treatment phase, the question is whether you are treating consistently and whether your attorney is receiving records as they are generated. If you are post-MMI and waiting for the demand to go out, the question is what is holding up the records assembly and whether that delay is the provider’s fault or the attorney’s. If the demand has been sent and the insurer has not responded meaningfully within sixty days, the question is what the plan is when the response period expires. If you are in litigation, the question is where you are in the scheduling order and what the next milestone is. The timeline is useful not as a prediction but as a map — it tells you where you should be and what should be happening at each stage, which gives you the ability to identify when something is off and the right questions to ask about it.
