Is My Brother Being Scammed By An Accident Attorney?

We are estranged from our parents so I don't know who to ask. My brother moved out the day he turned 18, and he's been on his own since. I am 28 and live in the same state (Georgia, USA) but almost 3 hours away.

A few weeks ago, he got into an accident that was not his fault. He was on the interstate and someone tried to get into his lane and hit him. He had a passenger, but they were both okay. His vehicle was also fine. This was in metro Atlanta.

Today, he told me that either a few days after or a week after the accident, he got a phone call from an accident attorney who told him that he could be owed up to $25,000 and that they wanted to represent him for this accident. I know the cold call from the attorney is unethical which is already raising a red flag to me.

They told him to not talk to his insurance so he has not, they've been advising him to go to chiropractic appointments, and he's getting an MRI. I don't believe any of this is going through his health insurance, but I don't know if that matters.

He's just so young and naive and he's already signed all the paperwork so I don't know what can be done. What I can tell you is I looked up the attorney and that office has an F rating on the BBB and a note saying they have been a victim of identity fraud, although the identity fraud that has been cited is them calling to try to collect an unpaid medical bill.

He keeps telling me that everything looks super legit so it's totally not a scam but I'm like, exactly. I don't think you understand how well scams can work. It's just really stressing me out and I don't have anybody that I can ask.

I think I'm going to ask him to get copies of everything he has signed so I can look at it and also see how he can get out of this. But he keeps saying that he's just going to go through with it and see what happens.
