Templates for Co-Parents.

A curated set of 4 templates for two households raising one set of kids — split expenses your own way, keep one running balance, count overnights against your schedule, and hold the records a co-parenting arrangement asks for. In files both homes own, not an account either one rents.

The math and the paper trail, in one place both parents can open

Co-parenting runs on numbers that should be simple and rarely are: this child's therapy is split 70/30, that one's activity fee is 50/50, one parent fronted the school supplies and the other paid back half, and by month three nobody agrees anymore on who actually owes whom. The Co-Parenting Expense & Records Log sets a percentage split for each of 12 expense categories — with an override per child for the one that's shared differently — and resolves it on every row, netting every payment, partial or on account, into one running "who owes whom" figure. It also counts scheduled versus actual overnights from a 14-day pattern, alternates the holiday rotation by year, and keeps a communication log, handover checklist, and records index alongside a year-end summary. Start free with the Co-Parenting Shared Expense Ledger — one tab, a single agreed split, and a running balance, pre-filled with a worked example.

Not every plan or agreement uses the same words for the same costs. See what counts as an extraordinary (add-on) expense for the categories people and plans commonly split beyond base support — and, if you're weighing an app against a file you keep, see spreadsheet vs. co-parenting app.

A few things nearby round out the same records. If you're still working through the separation itself — the asset and debt picture, a budget, the documents you need to gather — the Divorce & Separation Records Organizer holds that (see organizing your records for a separation). If a child has an IEP or 504 plan, the Special-Needs / IEP Records & Care Binder keeps accommodations, evaluations, therapy and meeting notes in one place both households can reference. And if either home also splits bills with a roommate, the Roommate Agreement & Bill-Split Spreadsheet runs the same kind of who-owes-whom balance for that arrangement.
