My ex and I share joint custody of our 3 children. I am the domiciliary parent of two and he is the domiciliary parent of 1. Based on the recommendation of a psychiatrist, we have agreed that we will continue to share joint custody of two children one living with me and one with him while I will have sole custody of our oldest child and he will have limited visitation. In the past, I've written and filed stipulated judgments, for custody & visitation, but this time I'm not sure what I need. Do I need separate documents for sole custody & joint custody? One document stating that the previous document still stands with the following exceptions and list the change from joint to sole custody for one child as one of the changes? Would one completely new document stating which child I will have sole custody of and which two we will share joint custody of be better? I am really lost and have to bring finished documents for my ex to sign on Sunday. This has been very sudden and I want to make sure that this is signed and filed before he changes his mind.
