What redress does a birthparent have if an open adoption agreement is not followed ?

None, unfortunately. Once rights are signed the adoptive parents have legal rights as the parent to allow or unallow contact. Always frustrates me to see/hear adoption plans not followed.

Just document efforts so you can find your bio child and introduce yourself when she is 18.

Consider speaking to a family lawyer just in case the state has laws people in this thread dont know of or, to see of they can apply pressure based on your original agreement to act as a buffer. Contact the adoption agency, too and see if they will help. At least if they are reputable they will make a call or decline working with the family if they renig this time, again.

Legally speaking, no redress.

If the child in this situation is still a minor, you can write a letter to her outlining your reasons for placing her for adoption, and how the adoption became closed, giving her your contact information, and send it to her when she becomes an adult (I'm assuming you have her parents' names and address since the adoption was originally open).

If I found out my original mom had wanted contact while I grew up and my parents had denied it, it would have put a strain on our relationship that is for certain.

Hopefully she will be willing to maintain contact in the future.

There isn't any as open adoption isn't worth the paper it is written. When an adoption is closed you can't do anything about it.

You haven't said how old your daughter is so it's hard to think of reasons why you're going througn this. She is the only one who can tell you exactly why she feels like this. It can range from she really feels this way / a phase she is going through through to the adopters being negative about you / fear of them 'losing' her to you.

All you can do is respect her / their wishes as this will make you a better person no matter what you really feeling inside.

Open adoption agreements rarely last. In most states, these agreements are not legally recognized. Even in the states that do recognize open adoption, the agreements are only enforceable if you had the agreement signed in court specifying what contact was allowed.

Sorry - but in the eyes of the couple you are not ""mom"". You signed away any and all rights to your child. You legally are not "mom" and have no rights to the child.
