The geographical area served by the Cork Interdiocesan Marriage Tribunal includes the six dioceses of:
- Cashel & Emly
- Cork & Ross
- Waterford & Lismore
Either party to the marriage must live in one of these dioceses OR the marriage took place in one of these dioceses if they wish to avail of the services of the Cork Interdiocesan Marriage Tribunal.
Four Marriage Tribunals serve all the Catholic dioceses in Ireland. As well as Cork, the other three are located in Armagh, Dublin and Galway.
