If you were rear ended and their insurance accepted liability but later the accident report stated that you abruptly stopped can they decline to pay?

Have they denied it? What report said you stopped abruptly? The other driver? They almost always say that, usually to no avail. More facts of loss details and I can help you more.

NO POLICE REPORT Was done company said they pay for damage, and now is not paying for the damage, i have insurance and my boyfriend was driving my vehicle with no driver license, can i pursue this
