What is a child expense sharing agreement?
After a separation, everyday costs during each parent's time are usually simple. The extras are what cause friction: a new activity signed up for without asking, a dental bill that arrives months later, or a reimbursement that never comes. A child expense sharing agreement sets one clear process both parents can follow.
This template lists the children and sets each parent's percentage share. It names the categories you share, with a full default list covering activities, school costs, uninsured medical and dental bills, childcare for work and school tech, and what each parent pays alone. Costs over an amount you set, and anything recurring, need the other parent's written agreement, with a reply deadline, and urgent medical care never waits. It sets deadlines for sending receipts and paying back, where costs are tracked, and that refunds and insurance come off first. It keeps money talk away from the children, uses mediation for disagreements, and says that any child support or court order comes first.

Using the child expense sharing agreement, step by step
1 List the children
Enter both parents and each child's name and date of birth, and the date the agreement applies from.
2 Set the split and categories
Enter each parent's percentage. Edit the list of shared costs and what each parent pays alone.
3 Agree the approval rule
Set the amount above which a cost needs agreement first, and how many days the other parent has to reply.
4 Set the paperwork, then sign
Choose deadlines for receipts and reimbursements, where you'll track costs and how you'll pay. Both parents sign online.
Tips before you send it
- A shared spreadsheet or co-parenting app with a photo of each receipt prevents most disputes.
- Put the item in the bank transfer reference. It makes the record easy to check later.
- If no reply arrives within the deadline, the cost counts as agreed, so reply even if the answer is no.
- Review the agreement when a child starts a new school or activity, not only once a year.
- If you have a court order, check it first. Some already set out how extra costs are shared.

Child expense sharing agreement: frequently asked questions
Does this replace child support?
No. It's in addition to any child support either parent pays and doesn't change it. Where a court order or child support calculation already covers a cost, the order comes first.
What if the other parent doesn't reply to a request?
If there's no reply within the days you set, the cost counts as agreed. Urgent medical or dental treatment never needs approval in advance.
Can we make this part of a court order?
Possibly, but that needs the court or your local process. The agreement says so. Signing it online makes it a written record between the two of you.
Can both parents sign from different places?
Yes. Each parent signs on their own device, and both receive the same signed PDF with an audit trail.
