HB 4011 amends the Uniform Partition of Heirs' Property Act to change the process for partitioning real estate jointly owned by heirs. It introduces stricter notice and due diligence requirements for non-heir cotenants seeking partition, mandates a court-supervised settlement conference before partition proceedings, and imposes a 10-year waiting period before non-heir cotenants holding less than a 50% interest may initiate partition actions. It also revises definitions and procedures to better protect heir property owners and clarify the responsibilities of non-heir cotenants.
