What you’ll take away

  • List each household separately
  • Identify shared commitments
  • Model transition costs

List each household separately

Record expected income and costs for each home, including housing, utilities, transport, food and childcare.

Identify shared commitments

Make a list of joint loans, rent or mortgage obligations, household bills and subscriptions. Separation does not automatically remove contractual liability.

Model transition costs

Allow for deposits, moving costs, furniture, legal fees and temporary arrangements. Avoid relying on an optimistic estimate of future support.

Review cash flow regularly

Update the figures as child arrangements, housing and maintenance change. Seek debt support early if essential bills cannot be met.

Try it yourself

Create two monthly columns and a separate list of joint liabilities with account holder, due date and next action.

Important limits and risks

Financial arrangements and legal entitlements depend on individual circumstances and jurisdiction; obtain legal advice where needed.

Putting your learning into practice

Use the guidance above to identify the information you need and the questions to investigate. Consider:
