Coupla quickies - we did a stepparent adoption in MO and it was VERY simple to do - our bio dad only had to sign and notarize a letter stating he gave up his rights - and we didn't have to have the court notify him of the proceedings because he voluntarily gave up rights. Also, in MO even if there is an error in an adoption proceeding, if one year goes by, it won't matter. The child is adopted and it is not contestible. This is so kids don't have bounce back parents - if this guy or gal did sign off his or her rights, most likely it is a done deal. Case.net will never show this because in MO adoptions even by stepparent are sealed; the birth certificate of my kids now reflects my hubby as their dad and their former parent is no longer on public record at all. Pretty weird huh? I think it is a good thing, but that is because I am on the one end of the deal; if I were a parent who somehow got screwed out of my kids ( forged adotion papers or something?) I would not be happy.
Anywho, check the statutes. Adoptions can't be revoked even for fraud, etc, after a certain time period. And "error of process" limits are one year. So if the guy didn't get notified and should have been ( I was unclear about whether he gave up rights and now is crying over it or had them terminated without consent ??) and a year has gone by - he is out of luck. MO is very reluctant to mess with a child's stability, as they see it.
