Mortuary law describes the body of law governing the handling, custody and disposal of human remains, including death certification, post-mortems, retention of organs and tissues, funeral arrangements and burial or cremation. It is a descriptive term rather than a single codified legal regime, drawing on statute, common law, professional regulation and local authority powers. Across England and Wales, Scotland, Northern Ireland and Ireland, core issues include: who has the right to possession and control of the body; consent to post-mortem examination; coroner or procurator fiscal investigations; licensing and regulation of mortuaries and crematoria; public health requirements; and disputes over burial, cremation or repatriation. Relevant legislation and case law vary by jurisdiction (for example, distinct coronial and burial/cremation statutes, and different approaches to quasi‑property interests in a body and to next‑of‑kin rights), but the underlying principles are broadly consistent. In practice, mortuary law is engaged by hospitals, funeral directors, local authorities, pathologists, faith groups and families, particularly where there is a contested funeral, delay in release of a body, allegations of unlawful retention of tissue, exhumation, or cross‑border transfer of remains.
