The bill introduces Chapter 15.1, the "Uniform Partition of Heirs' Property Act," to Title 34 of the General Laws, establishing a legal framework for partition actions involving heirs' property. Heirs' property is defined as real estate held in tenancy in common that meets specific criteria: there is no binding agreement among cotenants regarding partition, at least one cotenant acquired title from a relative, and at least 20% of the interests are held by relatives or individuals who acquired title from relatives.

The chapter specifies that partition actions filed after January 1, 2026, must adhere to its provisions. These provisions include determining the fair market value of the property, allowing cotenants the opportunity to buy out the interests of a cotenant wishing to sell, and establishing conditions for partition by sale or in kind. The court is required to notify all cotenants of partition actions and provide them the opportunity to buy out the selling cotenant's interest.

Additionally, the bill emphasizes the appointment of disinterested and impartial court commissioners and outlines the requirements for notice and service in partition actions. It details the process for selling the property if ordered by the court, promoting open-market transactions while allowing for sealed bids or auctions if deemed more economically advantageous. The act aims to create uniformity in the application of laws regarding heirs' property across states, ensuring fair and equitable resolutions in partition disputes.
