Minor in title

[Jim Viens]

Couple of questions. I have a property I'm about to get under contract. BUT...an initial title search shows that the property is actually in the name of the 14-year-old daughter of the guy I've been talking to (long story). My questions are: 

1) Could the dad sell the property on her behalf under a POA or do they have to file for a conservatorship?

2) How should the contract be executed (who can/should sign?)

Thanks in advance!
