Are registers signed during a Convalidation ceremony

My husband is Roman Catholic and I m Pentecostal. We married under a lot of pressure with no family members present. After much strife our families have agreed We have been trying to book a notice of marriage and are waiting for a reply. We may have to opt for a Convalidation which would destroy our families again as they might find out what we felt we had to do. We understand that a nuptial mass and a Convalidation are essentially the same But are registers still signed in a Convalidation ceremony?
