To negotiate a car accident settlement without a lawyer, you'll have to prove that the other party was to blame for your damages. Gather evidence at the scene to support your claim, including witness statements and photos. Seek medical treatment for your injuries immediately. Notify the other driver's insurer of your intent to file a claim. If you reside in a no-fault state, you will need to use your personal injury protection (PIP) benefits first before filing a claim against the other party for medical expenses and bodily injury. Be prepared with medical records, police reports, receipts for out-of-pocket accident-related costs, and proof of lost income due to the accident before beginning negotiations.
