Legal Question in Real Estate Law in North Carolina

Nothing prohibits an inmate from inheriting property unless his crime falls under the "Slayer Statutes" i.e. his inheritance is a result of killing the person from whom he is inheriting the property. Any of the beneficiaries can petition for a partition of the property if they cannot agree as to the use. This would create a circumstance where the court might order a forced sale of the property.

A marriage cannot be nullified unless certain acts occurred when you entered into the marriage (such as incapacity, age, etc.) These are what are known as void and voidable marriages. Otherwise, you will have to file for a divorce. Without further facts, I cannot be of much help.

Sorry about the "marriage" advice. That was from an earlier question that I answered, although it may come in handy in the future. Best of luck.
