I was riding shot gun in a car without a seat belt after a long night at the bars. My friend collided with a tree with his parents car and we both ended up in hospital. I received a fracture near my cheek bone and a broken tooth while he got a dislocated shoulder.

I lost my jacket, cell phone, and a pair of jeans were ripped and ruined. I also had my laptop in the trunk and surprisingly it still worked after but there is a huge crack and dent in the casing.

Can I claim these things under his insurance? He said he wasn’t registered under parents insurance, but his dad said his insurance company would cover my costs. Would that include this?
And how do I go about contacting the insurance company, do I just get their number and call them up?
Do I need receipts of the repairs done on my laptop, as well as the cost of a new cell phone and jeans?

The accident was a week ago, and the guy is my friend. I was considering whether or not I should seek legal advice?
