How a California Collision Insurance Claim Actually Works, Step by Step

June 18, 2026·3 min read·HADD Customs · Beverly Hills

Most people file one collision claim a decade. Here is the whole sequence, in order, so nothing about it is a surprise the next time you need it.

Almost nobody gets good at filing insurance claims, because almost nobody files them often. You file one, learn the process under stress, and forget most of it by the time the next one happens. What follows is the sequence we walk clients through every week at our Beverly Hills shop, laid out in the order it actually happens in California.

Step one is the report. Call your insurer and open a claim, even if you believe the other driver's carrier will ultimately pay. Opening the claim starts the clock on your own policy's protections — rental coverage, medical payments, uninsured motorist — and it does not commit you to using your own collision coverage. You will get a claim number. Write it down; every conversation afterward starts with it.

Step two is the assignment of an adjuster. In California, the insurer has 15 days to acknowledge your claim and begin an investigation, and 40 days from receiving proof of claim to accept or deny it. Those deadlines come from the Fair Claims Settlement Practices Regulations. Knowing they exist is useful, because an adjuster who goes quiet for three weeks is not simply busy — they are running out of regulatory room.

Step three is where most owners give up ground without realizing it. The insurer will offer to send you to a shop in their direct repair program, often described as "preferred," "approved," or "guaranteed." That is a recommendation, not an instruction. California Insurance Code section 758.5 prohibits an insurer from requiring you to use a specific repair shop. You pick the shop. Your insurer pays for the repair either way.

Step four is the estimate. Someone — a field adjuster, a photo-estimating service, or the shop you chose — writes an initial estimate. Treat that first number as a rough opening position, not a final figure. On a modern luxury car with bonded panels, sensor brackets, and one-time-use fasteners, an estimate written from photographs routinely misses a third or more of the real cost, because the damage that matters is behind what the camera can see.

Step five is teardown and the supplement. The shop disassembles the damaged area, finds what the photos missed, documents it, and submits a supplemental estimate. This is normal. It is not a shop padding a bill; it is the point at which guessing stops and measuring starts. A well-documented supplement, with photographs and the manufacturer's published repair procedure attached, is very hard for an adjuster to refuse.

Step six is authorization and parts. Once the supplement is approved, parts are ordered. This is usually the longest single stretch on a European car, and it is almost entirely outside the shop's control. A rear quarter panel for a current-model Mercedes may ship from Germany. A body-colored Ferrari component may be built to order. We tell clients the honest number rather than the comfortable one.

Step seven is the actual repair: structural work and measuring first, then body and panel fitment, then refinish, then reassembly, then calibration of any driver-assistance system the repair touched. Each of those stages has to be completed and checked before the next begins, which is why a repair that looks like "just a bumper" can still occupy a week of shop time.

Step eight is the final bill and the release. Your insurer pays the shop directly in most cases; you pay your deductible. If the other driver was clearly at fault and their carrier accepts liability, your deductible is typically recovered later through subrogation, and that can take months. Do not sign a release that describes the settlement as full and final until the car is back, calibrated, and driving correctly.

Two habits make all of this easier. Keep a single running note with the claim number, every adjuster's name and direct line, and the date of each conversation. And put anything that matters in writing — a short email confirming what was agreed on a phone call is worth more later than the clearest memory.

If you want the shop to handle the back-and-forth, that is a service, not a favor. We deal with adjusters daily, we know which procedures need documentation before they will be approved, and we would rather spend that time ourselves than have a client learn claims administration during a bad week.
