On the matter of "marriage convalidation" in the Catholic Canon Law, it states: THE CONVALIDATION OF MARRIAGE Art. Canon Law # 1157 The renewal of consent must be a new act of the will concerning a marriage which the renewing party knows or thinks was null from the beginning. If the impediment is public, both parties must renew the consent in canonical form, without prejudice to the prescript of Canon Law # 1127 2. If the impediment cannot be proven, it is sufficient that the party conscious of the impediment renews the consent privately and in secret, provided that the other perseveres in the consent offered; if the impediment is known to both parties, both are to renew the consent. A marriage which is invalid because of a defect of consent is convalidated if the party who did not consent now consents, provided that the consent given by the other party perseveres. If the defect of consent cannot be proven, it is sufficient that the party who did not consent gives consent privately and in secret. If the defect of consent can be proven, the consent must be given in canonical form. To remedy the situation, the couple must present itself as a couple to the parish priest.Canon Law # 1160 A marriage which is null because of defect of form must be contracted anew in canonical form in order to become valid, without prejudice to the prescript of ? It needs to demonstrate that it entered into the non-canonical marriage without malice or deception. First, let’s be clear that divorce and annulment are utterly different.One erroneously says an indissoluble marriage covenant can be ended before death (divorce), and the other truthfully says that sometimes an attempt at marital consent doesn’t really “make marriage” because of some defect (annulment).The position of the Catholic Church is very clear on this matter.
The Church rejoices with you as you prepare to enter the Sacrament of Marriage and embark on this great vocation of love and service.
Your engagement is also a great time to take Natural Family Planning (NFP) classes to learn more about the beautiful gift of fertility and prepare to live a marriage that is open to life and to God’s plan for your family.
For couples who are currently civilly married outside of the Church and would like their marriage to be recognized by the Catholic Church, please see Convalidation: Bringing Your Marriage Into The Church.
These programs come in many forms: weekend retreats, a series of evening meetings, one-day events, online programs, or meetings with a priest or mentor couple.
But they all share the common goal of providing engaged couples with the knowledge, skills, and formation they need to have a happy, holy, lifelong marriage.
