Sorry but unless you get medical care, not much of case; seek a refund.

Likely yes. You must disclose the money. If they do not count it as income you might be ok. That or you could try to set up a special needs trust...

Anyone can sue. Since she settled the propety damage I don't see how. Your insurance co. dosen't cover the loan amount, only the car's value....

Go thru your own ins. They will then go after them and try to get your deductible back.

He cannot apply for disability if he is still working.

Notify your insurance carrier ASAP. Let them deal with the issue. No they cannot put a lien on your home if its under homestead.

Request it from the police department request from your insurance co. If you were injured, see immediate medical care.

No as that's a waste of $ Only the police can do anything.

Unless you ate it, got sick and received medical care, there is no case.

I think there is no case. No injiury, no claim. What "could have happened" means nothing. Seek a refund.
