My question involves a marriage in the state of: TEXAS

My son and daughter-in-law are legally married, have decided to call it quits. She is about 12 weeks pregnant. While they both would like very much to keep the baby, they both know that neither of them can provide the best environment for the child financially. They told me that they have jointly decided to place the baby for adoption when he/she is born (DIL already has a 2 year old from prior relationship to take care of).

I do already know that in Texas, a divorce cannot be finalized while the wife is pregnant.

My question is - After the the child is born and placed with adoptive family, would the adoption papers just be substituted for custody arrangement, etc documents that typically are found in a more 'traditional' situation (divorce with kids?)

Any insight anyone can provide would be most helpful here.
