Do I have the right to bring my kids back to our home state?

True but my mom had an affair nearly my entire childhood and we knew about it - the whole town knew about it. Add in that she would take off every other weekend she had off work to see fact we were glad when she was gone. I wish my parents had divorced back then. I know she wouldn't have fought for custody of any of us except the youngest and we found out when she did finally leave and filed that the youngest was biologically the other guy's. But my dad has always legally been his dad as they were married when he was born. My mom finally left when I was 18, youngest was 12, other younger was 16 and oldest two were out of the house.
:( I was thinking more along the lines of - if these two kids aren't aware? Dad shouldn't clue them in.
