I have this property scenario "O to A for life, then A's widow for life, then to A's children living at the time of the widow's death." At the time of the conveyance, A is married and has 2 children.

I think these are my future estates.

A: Life estate

Widow: Contingent Remainder for life

Children: Vested remainder

Let me know if I am wrong

Would Shelley's rule or doctrine of worthier title change my estates above and how?
