A driver is stopped behind three cars at a red light on a four-lane arterial when a pickup hits her at maybe fifteen miles an hour. The other driver admits he looked down at his phone, the police report records no citation but a clear narrative, and her bumper cover and trunk latch come to a shade under four thousand dollars at the body shop. She goes to urgent care that evening, then to eight weeks of physical therapy for neck and upper back pain, and by the end of it she is sleeping normally again. The adjuster calls with an offer. That claim, on those facts, is one a careful person can run alone.
The claim that mostly runs itself
What makes it manageable is not the size of the injury but the absence of anything in dispute. Fault is admitted or obvious, the property damage estimate corroborates the force of impact, treatment started within a day or two, the records read in a straight line from complaint to discharge, and the wage loss is a matter of pay stubs and a supervisor's letter. In that posture the negotiation is arithmetic and patience: medical bills, documented lost earnings, and a general damages figure the adjuster is authorized to move on if you send a demand that organizes the file for him. You will get a first number that is low. You are allowed to say no, twice.
The cost of handling it yourself is real but bounded. You spend an afternoon requesting records and itemized bills, a small fee to the medical records vendor, and several weeks of phone tag. What you keep is the entire settlement. On a modest soft-tissue claim, a contingency percentage taken off the top can exceed anything representation adds, because there is no leverage to add. That is the whole argument for doing it alone, and it is a good one when the facts cooperate.
When liability is the case
Change one detail and the analysis flips. Suppose the other driver tells the responding officer that she stopped short for no reason, or the intersection has no witnesses and both drivers claim a green light, or the insurer assigns you a share of comparative fault and reduces its offer by that share. Now the file is not arithmetic. It needs signal timing records, a canvass for business surveillance video before it overwrites, sometimes a download of the vehicle's event data recorder, and a demand letter that anticipates the defense rather than reciting the bills. An unrepresented claimant almost never gets those things in hand within the window they exist.
Disputed liability is also where the percentage starts to pay for itself, because the gap between a comparative-fault discount and a full-value settlement is usually far larger than the fee. Before signing, ask the office how it would prove fault here, not in general. A firm that handles this volume of collision work, whether a large practice or a local Injury Lawyer who tries cases in the county where the crash happened, should answer with specific steps and a timeline rather than reassurance.
Injuries that are still moving
The second disqualifier is an injury that has not settled into a shape yet. A fracture with hardware, a disc herniation with a surgical recommendation, a head injury with cognitive complaints, any permanent impairment rating, any injury to a child: these are claims where the number depends on things not yet known, and where an early check signs away the expensive part of the future. Valuing them requires a treating physician willing to write about causation and permanency, sometimes a life care plan, and sometimes an economist for lost earning capacity. Those are costs advanced by a firm, itemized in the agreement, and repaid from the recovery. Read that clause carefully: case expenses are separate from the fee, and whether they come off before or after the percentage is calculated changes what lands in your account.
Workplace and medical injuries are a different system
An injury at work is not a negligence claim against the employer in most situations; it moves through workers' compensation, with its own notice deadlines, its own dispute procedure, and a separate question of whether a third party such as an equipment maker or a contractor on site is also liable. The Occupational Safety and Health Administration oversees workplace safety standards and employer injury recordkeeping, and the existence of an inspection or a citation can matter to a third-party case. Medical negligence is harder still. Most states require an expert affidavit or certificate of merit before the case can proceed, and the record review alone costs money no individual claimant should front. Neither category is a self-help project.
The test, in dollars
Write down the number the adjuster has offered, then the number you believe the claim is worth, then subtract the contingency percentage from that second number. If the difference still favors representation, and the file has anything contested in it, hire someone. If the two numbers are close and nothing is contested, the fee is buying you convenience rather than value, and you should say so plainly at the consultation. Ask what the percentage is, whether it rises when suit is filed, who pays costs if the case loses, and what happens if you part ways midstream. Those answers belong in writing before anyone signs.
The one deadline that does not negotiate is the statute of limitations in your state, and it can be shorter for claims against a public entity. Whatever you decide, decide it early enough that the choice is still yours to make.
