You can't force him to have parental time with his children, but he won't be able to not pay child support, even if he decides not to visit them.

It may even affect how much child support he must pay, as I believe it is based on the % of time each parent spends with their children. If I am wrong on that assumption, I am sure someone will step forward and correct my incorrect knowledge.

Do you have any idea why he doesn't wish to have parenting with his daughters? As far as his family also not wanting to acknowledge his children, I agree with Mistake....screw them....it just shows what total a$$holes they are.

I hope you have family nearby. They will more than make up for his family "checking" out.

Maybe one day, your stbx will pull his head back out of his a$$ and realize that he wants and needs to be a part of your daughter's lives. Miracles can happen, may it happen for your precious daugthers.
