A.P.
I'm not an atty, but most of them charge a small consultation fee that equals about $100 and covers about an hour if you or the daughter are really curious.
I also think it depends on the state where the will was written, but don't depend on me (because I'm not an atty.)so talking to a wills and probate lawyer from that state would be key.
From what I have seen in my family and others, the will is his last statement and testament, and it stands in favor of the daughter unless there is a later version signing over rights to the new wife. If GA is a community property state she may be entitled to things like his pension or part of any house they bought together, but again, you'd need to actually contact an atty in that state to find out the rules.
A good way to start is to contact a law school in GA. Lots of schools have community service programs that might give you some help, with aspiring young lawyers eager to test their knowledge of the law. Most of them do this for nominal fees, and they can even fill out paperwork and file court documents for you in many cases.
