Trust; judicial proceeding; venue; effective date.

HB 4353 updates Oklahoma's trust law to clarify where court cases involving trusts can be filed. It changes venue rules so that trust-related lawsuits must be filed in the county where the trust's main administration occurs, rather than solely where trustees reside. This affects trustees, beneficiaries, and courts handling trust disputes by streamlining where cases can be brought. The bill becomes effective November 1, 2026.
