In Catholic canon law, a validation of marriage or convalidation of marriage is the validation of a Catholic putative marriage. A putative marriage is one when at least one party to the marriage wrongly believes it to be valid.[1] Validation involves the removal of a canonical impediment, or its dispensation, or the removal of defective consent.[2] [3] However, the children of a putative marriage are legitimate.[4]
If the impediment to a marriage is a defective consent by one or both parties, a simple renewal of consent removes the impediment and can effect validation.[2]
When a couple has received a dispensation, the partners may validate the marriage by a simple renewal of consent according to canonical form as a new act of the will.[5] When the impediment had affected only one of the parties and the other was unaware of the impediment, only the one aware of the impediment must renew consent.[5] If the impediment is known to both parties, or the impediment is public, then a public renewal of consent by both parties is required.[6]
See also: Canonical impediment and Dispensation (canon law). A bishop can give a dispensation to an impediment, giving the marriage retroactive validation called radical sanation or sanatio in radice (Latin: "healing in the root"). Some impediments can only be dispensed by the pope,[7] others may be dispensed by the diocesan bishop,[8] while others cannot be dispensed (consanguinity in the direct line or in the second degree of the collateral line).[9]
Sanatio in radice retroactively dispenses the impediment and makes a putative marriage valid from the time the sanatio is granted.[10] The sanatio validates a marriage by reason of a consent formerly given, but ineffective because of an impediment.[10] When the impediment is removed or dispensed, the consent is ipso facto ratified and no renovation is required. In such a case, it is requisite that the consent of both parties to the marriage had not ceased and that their marriage had had the external appearance of a true marriage.
