Both those websites are now part of UpToParents.org. If you were ordered or referred to complete one of those websites, simply use UpToParents.org. As you’re opening your new account, you’ll be asked to describe whether you‘re (a) a divorcing or divorced parent, (b) a parent never-married to your co-parent, or (c) a spouse open to the possibility of a happy reconciliation.
Whichever one of these three versions of UpToParents.org you choose, your Certificate of Completion will show that you’ve complied with the order to complete the work.
