Relating to the partition or voluntary sale of real property owned by certain cotenants; amending the Uniform Partition of Heirs' Property Act.

SB 600 amends Texas property law to clarify procedures for partitioning "heirs' property" (inherited land owned by multiple family members). It requires petitioners to certify if property is heirs' property, include ownership details, and prove compliance with notice rules for potential heirs. The bill mandates posting notices on the property, filing affidavits confirming proper service, and appointing an attorney ad litem to locate unknown heir cotenants - especially when a non-heir cotenant initiates a partition action after 2025. This directly affects property owners, heirs, and non-heir cotenants involved in disputes over inherited land.
