The Uniform Partition of Heirs Property Act establishes a legal framework for the partition of real property held in tenancy in common, specifically addressing situations where the property is classified as "heirs property." The act defines key terms such as "heirs property," "partition by sale," and "partition in kind," and outlines the court's responsibilities in determining whether a property qualifies as heirs property. It mandates that if the court finds the property to be heirs property, it must appoint a special master to oversee the partition process, unless all cotenants agree otherwise. The act also stipulates procedures for determining the fair market value of the property and the process for partitioning the property either by sale or in kind.

Additionally, the act includes provisions for notifying cotenants about partition actions, the appointment of impartial commissioners, and the methods for selling heirs property, including open-market sales or auctions. It emphasizes the importance of fair valuation and equitable treatment of all cotenants throughout the partition process. The act modifies existing laws to ensure consistency with its provisions and is set to take effect 30 days after enactment, applying to partition actions filed thereafter.
