Agree what counts as a shared cost

Most uncertainty about money starts before anything is spent. Writing down which costs are shared, and which each home covers on its own, answers most questions in advance.

  • Often shared: school trips, uniform, clubs, childcare, and larger items such as a new coat or bike
  • Often covered by each home: food, everyday toiletries, and outings during that home's time
  • Worth agreeing separately: birthday presents, phones, and anything above an agreed amount
Formal arrangements come first

If you have a formal maintenance arrangement or a court order that covers costs, follow it. This guide is general information and not legal or financial advice for your circumstances.

Record each expense when it happens

A shared record removes the need to reconstruct costs from memory weeks later. Each entry needs only a few details.

  • What it was for and which child it relates to
  • The amount and the date
  • How it is split, for example equally or by an agreed percentage
  • A photo of the receipt

Parenting Apart keeps expenses in one place that both parents can see, with the split and receipt attached to each entry. The other parent can acknowledge an expense, or query it with a reason and discuss it alongside the entry.

Settle on a regular rhythm

Settling every small cost as it happens creates a steady stream of requests. A regular rhythm, such as once a month, keeps the conversation predictable.

  1. 1Pick a settling date that suits both homes, such as the first weekend of the month.
  2. 2Review the recorded expenses for the period together or separately.
  3. 3Raise questions about a specific entry in writing, with the receipt in view.
  4. 4Mark expenses as settled once payment is made, so the record stays current.

A running balance in Parenting Apart shows who owes what at any point, and settlements are recorded once paid. For regular costs such as clubs or childcare, a budget proposal can set a monthly or quarterly amount, with a quote attached.

Common questions

What if we disagree about whether a cost should be shared?

Refer back to the categories you agreed. If a new kind of cost comes up, agree how it will be handled before it is spent where possible, and add it to your list.

Do we need to keep every receipt?

Keeping receipts for shared costs makes each entry easy to check and avoids later questions. A photo attached to the expense is usually enough.
