A succession rights claim pertains to a legal action filed by a family member or household member seeking the right to continue residing in a rent-controlled or rent-stabilized apartment after the original tenant has vacated or passed away. In some jurisdictions, rent control or rent stabilization laws allow certain family members or individuals who have lived with the tenant for an extended period to succeed to the tenancy and maintain the regulated rent. Succession rights claims typically involve legal proceedings to determine eligibility and establish the successor's right to remain in the rental unit.
