Under Florida law, cremation must be authorized by the legally recognized next of kin or designated representative before it can proceed. The authorization is typically signed on a cremation authorization form provided by the funeral home or cremation provider. The legal order of priority generally follows this sequence: a person designated in a written declaration for final disposition, the surviving spouse, adult children, parents, adult siblings, and then other next of kin. If there are multiple family members of equal relationshipโsuch as several adult childrenโmost providers require agreement from the majority. Miami funeral homes and cremation providers will guide families through this process to ensure the authorization complies with Florida statutes governing final disposition and cremation.
