It depends. Some churches will rent the space for the money but will not participate in the ceremony. Others will allow the wedding with minimal counseling. Some will require application for special dispensation Fromm the Vatican and still others will just say no.
The only way is to ask the church or priest you wish to use.
You can usually get a dispensation for just about anything, if you're willing to pay.
But, really, if these people were not married before, I think they can be married in the Catholic church. My husband's nephew had a similar situation. His girlfriend got pregnant, had the baby, and 4 months later they had a full church wedding, white gown and veil and all, and right after the wedding ceremony they had the baby's baptism. Now, those were interesting wedding photos :-)
It depends on the church. My friend was 6 mos pregnant when she married ( in a Catholic Church ). After several counseling sessions and a battery of compatibility tests they were deemed 'fit' to marry in the Catholic Church.
If you have never been married at all, of course you can marry, regardless of how many children you have had out of wedlock!
This woman is probably free to marry in the church. The church is not judgmental regarding her child.
I was 'married' for 32 years to the father of my four grown children. We divorced. We got a church annulment. Now, even I can marry in the Church!
It is usually impossible to marry in the Church if the bride is pregnant. The reason is that thee Church does not want a marriage for convenience or a shot gun wedding. The priest usually advises the couple to wait until after the birth of the baby to have the Church wedding.
I wish your friends congratulations and best wishes for a blessed marriage!
