The Church doesn’t have a particular view of them that is different from any other kids. The kids of parents who have had an annulment are going to church, attending Catholic school, etc., as far as I know, without any stigma.
The folks at the diocesan marriage tribunal tell me that every year, when adult converts are getting baptized at Easter, there are some annulments of prior marriages that are completed in time for the baptism. I doubt any of those converts are experiencing any stigma toward their kids from their annulled marriage, or they would not be so eager to join the church.
Ok you answered my question.
Thank you!
