Insurance; property insurance; abandoned oil and gas wells; coverage; subrogation; effective date.

HB 3804 requires all property insurance policies covering residential homes in Oklahoma to include coverage for structural damage caused by abandoned oil and gas wells beneath, adjacent to, or on the property. It prohibits insurers from excluding, limiting, or denying such coverage based on causes like subsidence, methane intrusion, or pre-existing wells. The law mandates coverage for structural repairs, soil remediation, well plugging (as required by the Oklahoma Corporation Commission), relocation costs, and testing. Insurers gain subrogation rights to recover costs from responsible parties (like prior operators or the Orphan Well Fund), but homeowners retain independent legal rights. The bill takes effect November 1, 2026.
