Peterson Law Group, PC | Erin Keeler
If your sister is not a beneficiary of the estate (not named in the will) she is not entitled to receive property of the probate estate. However, because she is the child of your parents she has rights and is entitled to notice of any probate proceedings of your parents that are initiated. The fact that she is in and out of jail usually is irrelevant for purposes of people receiving property through inheritance, with minimal exceptions.

Assuming your parents' wills are properly done and that they only provide for you, then your sister would not have any rights to their estate after they pass away unless she is also a dependent of your parents. A dependent would be entitled to a small award from the estate.

Your sister would likely not have any rights to your parents' property, unless your parents have named her as a beneficiary in their respective Wills, they have named her as a beneficiary on an account or asset owned by your parents, or is otherwise is entitled to property through state intestacy law - in the event that your parents did not have a Will, or their Wills are invalid.

Donaldson Stewart, PC | Monica H. Donaldson Stewart
If the will is valid, then it would control the distrubion of the property. If the will leaves their property to you, then the fact that she is in and out of jail may not be relevant. I recommend you speak with a probate attorney to determine your rights.
