Q. What if my spouse does not want to get married in the Church?

In special circumstances, a Roman Catholic person can ask the bishop of his diocese, to have their invalid civil marriage “sanated”. According to the law of the Church: 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- Can. 1161 §1. Note that in order for a sanation to be granted the persons must be free to marry in the Church; the consent to marry given in the civil ceremony must continue and there is no danger of separation or divorce. After sanation is granted the soliciting party is able to approach the Sacraments and participate fully in the life of the Church, and the marriage is recorded in the local parish.
