Son has half brother but father won't introduce

[autumn31]

What is the name of your state? Illinois

My son's father had another son three months before my son was born. I knew about his ex-girlfriend and the fact that she was pregnant, but she was never told about myself or my son. My son is now three and I want him to have the chance to get to know his half brother, but my son's father won't tell me who the mother of his other son is so I can find out if she feels the same way I do and let our children get to know each other and grow up knowing that the other exists. My son's father has absolutely nothing to do with him by his own choice, but has a relationship with his other son.

Is there a law that would allow for me to find out who the other mother is so that my son can get to know his own half brother or I guess I should say is there a law that entitles my son to know this information and I as his guardian have a right to it?

I don't think so.....but since you know when he was born, you might want to go over the birth announcements for that town for when the child was born- that may narrow your feild.....

There is no such law, sorry.

Thank you, I had a feeling that there wasn't a law that would help us out, but thought it was worth a try.
It's a shame that there isn't a law, children should have the right to know their family.

keep in mind though that dad cannot also not legally forbid you and the other mom from talking and allowing the children to know each other- so if you can find her.....
