This is the scenario:
Father had a child with his first wife.
First wife died when child was under 16.
Father remarried, relationship with child broke down and now-grown up child was entirely estranged from father and stepmother.
Father and stepmother remain childless.
Decades later, Father died having had no further contact with son. No will was found so the stepmother / second wife eventually inherited everything.
Stepmother died ten years later; again, there was no will.
Would the estranged stepson have a claim on the late stepmother's estate even though he was not blood-related to her? Or would it go to more distant blood relatives on her own side of the family? (These would be cousins or their children, as stepmother had no siblings)
Grateful for any help here. Thanks,
