Alienation of church property is governed by both canon law and civil law, which may give rise to conflict. This paper addresses issues surrounding the Roman Catholic canonical requirements for alienation including the need to consult experts. Failure to consult, itself may give rise to concerns over the validity of the diocesan bishop's permission to alienate and, in turn, the lawfulness of the sale. This is not merely academic. Churches in the United States find themselves in the position where ownership of temporal goods is of increasing interest to the civil courts in the pursuit of compensation for successful litigants in the current wave of abuse cases.
