That makes no sense. She had visitation... so he's petitioning the court for her to take 50/50???
There is one reason for bolting... if she wasn't ready to parent.
The courts force mediation on you... and Parenting After Separation courses... they could have worked it out without a hearing and had a consent order done without appearing before a judge.
" A Caseflow coordinator will give information about resources available to help parents resolve their disputes. Parties may be referred to mediation or other Family Justice Services programs. If the parties are able to reach an agreement, the Caseflow coordinator may prepare a consent order for them, allowing them to finalize their matter without going before a judge. Examples of order that may be prepared are:
• Parenting Order
• Contact Order
• Guardianship Order
• Grandparent Contact Order
• Child Support"
