Quoting ChristinaLynne:" How is your dad getting custody going to stop him from having rights to his children? If he is paying ... [snip!] ... and see them. Which if he's doing everything right he should be allowed to see them. I'm missing something somewhere."
Where i live, the law is after 6 months of no contact with your children, if someone is willing to adopt them, (my dad but not in the true sense of adoption like i said. They're still 100% my kids i'd still have 100% rights) it will render the SD's rights terminated.
He is NOT doing everything right!! HE'S doing nothing at all!!
