The Personal Injury Demand Letter: What It Is and What Happens Next
Short answer: The demand letter is the formal opening of settlement negotiations — a documented presentation of liability, injuries, and damages, ending in a specific dollar demand with a deadline. Templates exist everywhere; what makes a demand effective is not the format but the timing (after your medical picture is stable) and the evidence behind every sentence.
What a demand letter contains
A serious demand package has four parts. The liability section lays out why the insured is at fault, citing the police report, witnesses, photographs and — where relevant — statutes or regulations violated. The injury section walks through diagnosis and treatment, provider by provider. The damages section itemizes medical bills, future care, lost income, and the non-economic harm — pain and suffering — with the documentation attached. It closes with a specific amount and a response deadline. It is a preview of the trial the insurer will face if it says no.
When it should be sent — the part templates get wrong
The demand goes out when your damages are actually knowable: at or near maximum medical improvement, when physicians can say what recovery looks like and what future care costs. A demand sent early, while treatment is ongoing, values the case on incomplete information — always in the insurer's favor — and a supplemental demand later negotiates from a weakened position. The pressure to send it early is real (bills are piling up); resisting that pressure is a large part of what representation is for. The outer boundary is Arizona's two-year statute of limitations (A.R.S. § 12-542) — see the Arizona deadlines.
How insurers respond
Four ways: acceptance (rare on first demand), a counteroffer that starts real negotiation, a request for more documentation, or silence past the deadline. Each has a next move, and the credible next move behind all of them is the same — a filed lawsuit. That is why a demand from a firm that tries cases reads differently to an adjuster than the identical letter from a claimant alone: the deadline means something. If negotiation stalls, the path continues as described in how a personal injury lawsuit works.
Policy-limits demands
Where injuries clearly exceed the available coverage, a time-limited demand for the policy limits puts the insurer in a difficult position: refuse, and it may owe more than the limits later for failing to settle in good faith when it could. These demands are technical, deadline-driven, and one of the highest-leverage tools in serious cases — and they must be done precisely.
The evidence package behind the letter
A demand is only as strong as its enclosures: the complete medical records and itemized bills, the police report, photographs of vehicles and injuries, wage-loss documentation from the employer, and — in larger cases — physician statements on future care and permanency. Adjusters are graded on documentation; a demand whose every assertion has an exhibit gets evaluated seriously, while an unsupported number gets a formula response. Assembling this package is most of the work, and it is why the letter cannot outrun the treatment.
Why demands fail
Three patterns account for most failed demands. Sent too early — the damages were guesses, and the insurer priced the guess. An unsupported number — a demand that says "$300,000" without the records to force that valuation invites a counter at a fraction. And no consequence — if the insurer believes the claimant will never file suit, the deadline is decoration. The common thread: a demand letter is not a magic document but the visible tip of a prepared case. Prepared cases settle well; unprepared letters, however well written, do not.
What happens between demand and resolution
Expect rounds: the insurer's first response, a counter supported by whatever it disputes (treatment it calls excessive, fault it shifts to you), your reply addressing each point, and movement toward a number — or an impasse that turns into a complaint. Each round is faster than the first because the file is built. The negotiation is the trial in miniature, argued to an adjuster instead of a jury, and it is won with the same materials.
Should I write my own demand letter?
For a minor claim with completed treatment and clear fault, you can. For anything serious, the letter's power comes from the litigation threat and the documentation behind it — the things a template cannot supply.
How long does the insurer take to respond?
Demands set deadlines of two to four weeks; responses commonly take several. Silence past the deadline is an answer too, and filing suit is its reply.
What if the insurer's counteroffer is low?
First offers usually are — they test whether you know the case's value. Negotiation from a documented demand, with trial as the alternative, is how the number moves.
Is the demand amount what I will actually get?
The demand anchors negotiation and is set with negotiating room. Where it lands depends on the strength of the file — the factors in what your case is worth.
