SB 600 amends the Property Code to refine the rules governing the partition or voluntary sale of real property owned by heirs. It modifies the Uniform Partition of Heirs’ Property Act, adding new definitions, procedural requirements, and rights for heirs. These include mandatory notification to heirs, the right of first refusal for cotenants, and the ability to request settlement conferences. It also introduces rules for determining the fair market value of property and restricts non-heir cotenants from initiating partition actions under certain conditions.
