My husband and I were both raised Protestant and baptized as children. When we married, neither of us was religious so we had a civil ceremony at the justice of the peace, and not a church wedding. I have been attending Mass at a Catholic church for a while and am considering starting RCIA and joining the church next year. If I do, will we need to have our marriage convalidated to make it valid?
If you are both baptized, you both are attached to the Church’s economy of grace, (albeit imperfectly, unless and until both of you finish RCIA and come into full communion with the Catholic Church,) therefore, presuming that there are no other mitigating circumstances, your marriage is sacramental. The Canon is clear on this, a valid marriage cannot exist between two baptized people without it being necessarily sacramental.

Thus, it does not seem that you would have to get your marriage convalidated or take any other steps. The only thing that changes once you fully enter the Catholic Church, is that you have a right and obligation to provide a Christian education in accordance with the teachings of the Church to any children you two have. Does this help?
God bless!
