Legal Question in Wills and Trusts in Texas

Re: What happens when someone with two daughters dies without a will?

In Texas an adopted child has all the inheritance rights of a natural born child. They should divide the estate evenly. But the adopted daughter will have to file an action in probate court to determine heirship, and to appoint an administrator to handle the division of the estate, since the sisters obviously would not trust each other to do so.

Insofar as the possible insurance policy is concerned, you'll just have to start making phone calls to see which company, if any, the father had insurance with. Once you find out, you'd have to send them notice that he had died and that the policy should be paid. The insurance company would tell you what documents they need before they could pay on the policy. If the other sister won't cooperate in telling you where he had insurance, you'll just have to dig out the information by sheer grunt work.
