The advice of the Archdeacon should always be sought before any negotiation
or commitment is entered into. The written approval of the Area Bishop must
be obtained before any other Christian group is allowed to use a church or church
premises. An exchange of letters, an agreement about contributing to costs,
and the establishment of regular user group meetings are necessary to facilitate
such arrangements. No tenancy can be created in a church building; but a licence
under faculty may be appropriate in certain circumstances. If there is genuine
ecumenical co-operation in the work of the parish, a formal sharing agreement
should be considered (see LEPs).
