First-Party Claim vs Third-Party Claim
A first-party claim goes through your own insurer, a third-party claim goes through the other driver's, and either can be used.
Your contract only binds one of these insurers, not both
When you were hit by someone else, you have a right to be paid by that driver's insurer because their policy promises to cover damage they cause. But that promise isn't a contract with you. You're an outside party asking them to honor an obligation, and nothing forces them to move quickly or to agree with your version of what happened. That's why their adjuster can question fault, offer a low number, or drag out a rental approval. They're managing their own policyholder's liability, not serving you.
Your own insurer is different. You have a direct contract with them, so if you carry collision coverage, you can file a first-party claim and they have to treat you fairly and pay out according to your policy terms, regardless of fault. They pay first, then go after the other driver's insurer themselves through subrogation. That shifts the burden of proving fault off your shoulders and onto two insurance companies instead.
The tradeoff is cost and control. Using your own collision coverage usually means paying your deductible upfront, and it can affect your claims history even when you weren't at fault, though many insurers waive this when fault is clear. A third-party claim avoids your deductible entirely if it's paid in full, but you're waiting on a company with no obligation to move fast.
Which path makes sense depends on how clear fault is, how reachable the other insurer is, and how badly you need your car back now. Check your own policy for deductible waiver rules and rental coverage, since these vary by insurer and sometimes by state.

The short version
A first-party claim uses your own insurer, paying regardless of fault but often requiring your deductible upfront. A third-party claim goes through the at-fault driver's insurer, which owes you nothing contractually and can stall your claim. If fault is clear but the other insurer is slow, file first-party and let your insurer recover costs from them.

When the other insurer stalled, switching claims moved things forward
A driver was rear-ended at a stoplight with clear fault on the other side, a police report, and witnesses. She filed a claim with the at-fault driver's insurer expecting a quick payout, but the adjuster took over a week just to return her first call, then asked for a recorded statement before approving any repair estimate. Her car sat undriven the whole time and the rental coverage she needed wasn't moving either.
She switched to a first-party claim using her own collision coverage, paid her deductible, and had an adjuster assigned within days. Repairs started immediately and her insurer handled getting the deductible back from the other side once liability was confirmed. She ended up whole on the money, but weeks sooner, and without having to negotiate directly with an adjuster whose job was to protect someone else's policy.
Now that you know which claim path fits your situation, compare quotes to see how deductible and rental terms differ.
Will using my own insurance after a no-fault accident raise my rates?
Usually not, if fault is clearly on the other driver. Most insurers code a claim as not-at-fault once the other driver's liability is established, often through their own investigation or a police report, and not-at-fault claims typically don't affect your premium the way an at-fault claim would.
The exception is when fault is disputed or unclear at the time you file. If the other insurer denies liability or there's no clear evidence, your insurer may treat the claim as fault-pending until it's resolved, which can briefly affect how it's recorded. Ask your insurer directly how they classify not-at-fault claims and whether anything shows on your record while subrogation is still in progress, since this varies by insurer.

Can I switch from a third-party claim to a first-party claim later?
Yes, you can generally switch at any point before the claim is settled or you've accepted a final payment. If the other insurer is slow, difficult, or disputes fault, you can open a first-party claim with your own insurer in the meantime without losing your right to recovery. Tell your insurer you already filed with the other side so they can coordinate and avoid duplicate payments. Check your policy for any timing requirements on reporting a claim, since waiting too long can occasionally complicate things.
Do I have to give a recorded statement to the other driver's insurer?
No, you're not obligated to give the other driver's insurer a recorded statement, since you have no contract with them. You can decline, or agree to answer questions in writing instead, which gives you time to think through your answers. You are typically required to cooperate with your own insurer if you've filed a first-party claim, since that's part of your policy agreement. If you're ever unsure what you're required to say to either side, ask before the call, not during it.
Who pays my medical bills if I was hurt in the accident?
It depends on your coverage and your state's rules, since some states require your own insurer to pay initial medical costs regardless of fault through specific coverage, while others expect you to seek payment from the at-fault driver's insurer directly. Check your policy for medical payments or similar coverage, since having it means faster payment without waiting on fault to be resolved. If you don't have that coverage and injuries are significant, the at-fault driver's insurer becomes responsible, but payment can take longer.
