Can one family member in Pennsylvania sue another?
Yes. One family member can sue another for his or her injuries in an auto accident situation where one family member was driving and the other was a passenger - as long as the passenger didn't cause the accident. However, either your insurance company (or theirs, if different) would likely pay for your damages before a lawsuit was necessary. It's wise to contact a Pennsylvania car accident attorney to discuss your situation - especially when it involves family members.
