Do you have rights to estate before parent dies?

An estate can refer to all the property a person owns both real and personal. However, the term is more commonly used to refer to all the property that a person owns at death, both real and personal. You have no rights to your parents' property while they are alive. You may not have any interest in it after their death if they have made a valid will devising their property to someone else. Children can be disinherited in many jurisdictions.
