I had a bad car accident -my brakes in Toyota Camry suddenly stopped working in freeway

Unless you suffered severe permanent injuries it is too expensive to pursue this type of case.

I fell in the hospital in the hall way on some water and really messed up my knee. What is the hosital responsible for?

It all depends on how the water got on the floor and how long it had been present?

My friend in a county jail broke his hand in a fight, but wasn't allowed to see a doctor for 19 days can he sue?

He technically has a claim if he can prove that the delay caused additional injury bu it is unlikely that any private attorney would accept the claim.

You have little real recourse if the statement was made by a 3rd party. The person was a jerk.

I sold my car to someone who never transferred the title. They caused and accident and many tickets that are in my name now.

Do you have a bill of sale or cancelled check as proof of payment?

Can I report an accident that I was involved in hours later?

Yes of course you can.

Yes as long as you have the object and an x-ray showing it in your throat or stomach. You will need a personal injury attorney.

If a PI takes a video, and that video is used as a threat to be released to friends and family, is that legal?

Every state has a different law but generally it can be used for lawful purposes only.

I am being sued by a car insurance company

You need to hire an attorney to defend you.

Please explain the differance between a summons and a supyna

A summons is directed to a defendant and a subpoena to a witness.
