Insurance Coverage Q&A: Ownership, Garaging and Liability Coverage

If a daughter and father are both named on the vehicle title and the daughter gets her own PAP. So now she has a separate policy from the father. However, he is still named on the title with the daughter so does the father have PAP liability coverage on his policy if a claim occurs involving that vehicle? Would the father have coverage on her policy, on his policy, on his Umbrella policy? Would her limits defend him until exhausted and then his would kick in?
