Jenelle Evans and her baby daddy, Nathan Griffith, finally have a plan to share custody of their son -- and its gonna require a third adult ... Nates ma.
A judge has signed off on the custody arrangement between the exes to parent their son, Kaiser ... and it includes a detailed schedule. According to the docs, Jenelle retains primary physical custody of the 6-year-old, while Nathan gets him every other weekend.
Kaiser will also be jumping around between households on holidays -- on even years, hell be with his mom for Thanksgiving and with his dad for odd. Come Christmas, Kaiser is set to celebrate with Jenelle on Christmas morning, and then with his dad later that day ... and until the 27th.
Nathan was granted a significant amount of time to be with Kaiser for the summer -- 6 weeks straight once schools out. For Mothers and Fathers Day -- well, that ones easy.
Both parents will share legal custody of the kid, and have to figure out exchange points among themselves. Kaiser also cant be more than 2 hours away from Jenelle when hes visiting dad. And, per the judge, neither parent can trash talk each other in front of him.
Youll recall ... Nathan vowed to get custody of Kaiser last year, claiming Jenelle was an unfit mom and was turning his son against him. Looks like they were able to work out their differences after all that time ... good deal.
