Can. 1161 §1. The radical sanation of an invalid marriage is its convalidation without the renewal of consent, which is granted by competent authority and entails the dispensation from an impediment, if there is one, and from canonical form, if it was not observed, and the retroactivity of canonical effects.
§2. Convalidation occurs at the moment of the granting of the favor. Retroactivity, however, is understood to extend to the moment of the celebration of the marriage unless other provision is expressly made.
§3. A radical sanation is not to be granted unless it is probable that the parties wish to persevere in conjugal life.
Can. 1162 §1. A marriage cannot be radically sanated if consent is lacking in either or both of the parties, whether the consent was lacking from the beginning or, though present in the beginning, was revoked afterwards.
§2. If this consent was indeed lacking from the beginning but was given afterwards, the sanation can be granted from the moment the consent was given.
Can. 1163 §1. A marriage which is invalid because of an impediment or a defect of legitimate form can be sanated provided that the consent of each party perseveres.
§2. A marriage which is invalid because of an impediment of natural law or of divine positive law can be sanated only after the impediment has ceased.
Can. 1164 A sanation can be granted validly even if either or both of the parties do not know of it; nevertheless, it is not to be granted except for a grave cause.
Can. 1165 §1. The Apostolic See can grant a radical sanation.
§2. The diocesan bishop can grant a radical sanation in individual cases even if there are several reasons for nullity in the same marriage, after the conditions mentioned in ⇒ can. 1125 for the sanation of a mixed marriage have been ful-filled. He cannot grant one, however, if there is an impediment whose dispensation is reserved to the Apostolic See according to the norm of ⇒ can. 1078, §2, or if it concerns an impediment of natural law or divine positive law which has now ceased.
