If a pastor is informed that a member has without notice united with a church of another denomination, the pastor shall make diligent inquiry. The Annual Conference will make reasonable efforts to assist the Local Church in completing the required petition, which will include this.You can do is to end your membership in The UMC. If the member does not comply with any of the available alternatives over a period of two years, the member's name may be removed. An annual conference then must approve that request. The Book of Discipline provides that members can be removed from the membership role if they "transfer, die or have withdrawn from membership."
