I divorced in 03 she has custody, but my son has lived with me since May of 09′ Now she has hired an attorney to get him back. Will filing a parenting plan stop a big custody fight?

At the passing of my mother last year I found the court papers of my given birth name. The adoption records were sealed.
Whats the process to find birth parents names?

My fiance has 3 kids from a prior marriage, 2 of them still minors. The kids were taken away from us over the summer because my fiance cancelled their trip (that was scheduled on his parenting time) to their grandma’s. The kids were planning to go to grandma’s and not come back because their grandma is rich and they have friends down there. Now, Christmas is coming, and 1 of the kids have accepted our apologies while the other is calling us stupid etc. The mother is constantly reminding the kids of how her relationship with their father was (it wasn’t pretty, but he never hit, abused in any way his children, she couldn’t keep her legs or mouth shut). She also tells them that he doesn’t love them because he’s barely there to see them… he lives in another state and working 80 hours a week to pay their child support, his rent, car payment, taxes whatever else you can think of. My fiance and ex always argue, pretty ugly convers. what will the friend of the court do in this case?
