Try out Craig Lusk from
http://www.luskandevans.com/ . I have not had any business related dealings with him (thankfully....), but I know him from our kids and sports teams and know that he is a successful lawyer and he specializes in family law, which is what you are needing.
And by all means, if there are other suggestions posted here consider them as well (there is nothing in this for me), but I think Mr. Lusk could be of assistance.
Best of luck to you and your family.
