How to track custody expenses for family court

If you’re involved in a family court case, or think you might be, keeping a proper record of shared childcare expenses is one of the most practical things you can do right now. Not later. Now.

Courts don’t just look at what you claim. They look at what you can prove. This guide walks you through what counts as a shared expense, how to document it, and what format is actually useful to a lawyer or legal team.

What counts as a shared custody expense?

A shared custody expense is any cost directly related to your child’s welfare that isn’t already covered by child support, and which both parents are expected to contribute to.

Common examples include:

School uniforms, stationery and trip fees
After-school clubs, sport or music lessons
Childcare during holidays or school closures
Travel costs related to contact arrangements
Medical or dental costs not covered by the insurance or national health services

Day-to-day spending during your parenting time: food, entertainment and clothing you choose to buy, generally does not count as a shared expense. The distinction matters.

Why documentation matters more than memory

In disputed cases, courts frequently encounter two parents with entirely different accounts of what was spent, when, and whether the other parent agreed. Without a contemporaneous record, something created at the time, not reconstructed months later it’s one person’s word against another’s.

A legal team cannot build a cost schedule from memory. They need dates, amounts, what the expense was for and ideally evidence that it was communicated to your co-parent.

“The biggest problem we see is parents who kept everything in their head. By the time they come to us, they’ve lost months of records that would have been straightforward to produce.” - a common observation from family law practitioners.

What format should your records be in?

There is no single mandated format for expense records in family proceedings. However, what courts and lawyers find most useful is a clear, dated, itemised log that includes:

Date of expense
Amount (in your local currency)
Category (school, medical, childcare, etc.)
Brief description
Whether the co-parent was notified or agreed
Receipt or supporting evidence (where available)

A spreadsheet can work. A notes app is better than nothing. But neither is ideal because both can be edited and neither produces an audit trail that holds up well under scrutiny.

The timestamp problem

Courts are rightly sceptical of records that appear to have been created all at once before a hearing. If your log has 40 entries all created on the same day three weeks before your court date, that’s not a good record, it’s a reconstruction.

What makes a record legally credible is that it was created at or near the time of the event, by the person it concerns and that it hasn’t been altered since. This is why server-timestamped, tamper-evident records carry significantly more weight than anything you’ve typed up yourself.

Receipts and supporting evidence

Where you have receipts, keep them. A photo is fine, you don’t need the physical copy. Store them linked to the relevant expense entry so the connection is obvious. A receipt alone means little; a receipt attached to a dated, logged entry is much stronger.

Communication records matter too

If you submitted an expense to your co-parent and they agreed or refused, that should be logged. Courts look at patterns: was one parent consistently contributing, consistently refusing, consistently going off-piste without discussion? A message log that shows you asked, they agreed and the expense was paid tells a cleaner story than an unexplained credit card statement.

Practical steps to start today

You don’t need to wait for a court date, a lawyer’s advice, or a specific moment to start. Every day you don’t log is a day you’ll wish you had later.

Start logging expenses as they happen, not at the end of the month
Note the date, amount, category and whether it was agreed
Attach a photo of any receipt at the time, not later
Keep a separate note of any expense your co-parent refused, with the date and how you communicated it
Use a tool that timestamps your entries automatically

The records you create today are the evidence you’ll rely on tomorrow.
