Custody Exchange & Expense Tracking App Guide (GPS Check-Ins + Receipt Splits)
Updated October 17, 2026 · Reviewed by the ParentDocket Editorial Team · Educational information, not legal advice. Courts decide admissibility.
Two of the most common flashpoints in post-decree family court motions are contested custody exchanges (chronic lateness, no-shows, or arguments at the curb) and unpaid child expense reimbursements (medical copays, braces, sports fees, and daycare).
Without objective documentation, both issues degenerate into "he-said / she-said" arguments in front of a judge. Here is how to document every pickup, drop-off, and dollar spent so the facts speak for themselves.
Part 1: Documenting Custody Exchanges with GPS Check-Ins
When a parenting plan specifies "Exchange at 5:00 PM Friday at the Oak Street Library parking lot," how do you prove you were there at 4:58 PM and the other parent arrived at 5:47 PM?
- GPS-Verified Check-Ins: When you arrive at the pickup or drop-off location, tap Check In inside ParentDocket. The app records your server-verified timestamp and GPS coordinates.
- Contemporaneous Private Journal + Photo Proof: Attach a timestamped photo (for example, the exchange location clock or receipt) to a Private Journal entry. ParentDocket immediately computes a SHA-256 cryptographic hash of the entry and attachment, proving it was created at that exact moment.
- Neutral Curbside Exchanges: Keep all arrival updates inside ParentDocket's sealed chat (with Tone Check active) so you never have to engage in driveway arguments.
Part 2: Tracking Shared Child Expenses & Medical Reimbursements
Most custody orders require parents to split out-of-pocket medical, dental, vision, therapy, and agreed extracurricular costs (such as 50/50 or 65/35) and submit receipts within a set window (often 30 days). Spreadsheets and texted receipt photos fail because receipts get lost and running balances become disputed.

How do you prove a co-parent was late or missed a custody exchange?
Use ParentDocket's GPS Check-In button when you arrive at the exchange location and log a Private Journal entry with any supporting photo. Both records carry server-synchronized timestamps and SHA-256 hashes that export to a Certified PDF.
How does ParentDocket track shared child expenses and receipts?
You upload a photo or PDF of the receipt, select the child and category (medical, school, extracurricular, childcare), enter the total amount, and ParentDocket automatically calculates each parent's share and tracks reimbursement status.
Can I export an itemized expense report with receipts for family court?
Yes. ParentDocket exports a Certified PDF Expense Report showing every line item, date submitted, split percentage, reimbursement status, and attached receipt documentation.
