Does anyone have a referrals for a good family law/ probate attorney in denver?

My issue:

My dad recently passed, had no will ( well he had an old one that was written in 1974 when it was just my mom who was deceased in 1992 and myself as hiers )
Its going to be a messy deal with regard to my mother in law and her two kids who he adopted.

I have no idea where any of his stuff is, how to find it or anything.


thanks in advance!
