Your step father contacted you saying his father died and his children were named in his will to receive the interest from some land his father owned You are 36 and he how do you find out what is mine?

Your step father's father died and you think you are entitled to something? Did your step father adopt you? If he didn't adopt you, there is probably no entitlement, unless you were specifically named in the will.

The executor of the estate, who may be your step father, will have to show the courts that he distributed the estate as the will specified. If you are in the will, you are entitled to be able to read it. If you are not in the will, and were not adopted, they don't have to share it with you.
