Monthly Expense Budget for Divorce in Singapore — What the Court Needs to See

Why the Court Cares About Your Monthly Expenses

When the Family Justice Courts decide spousal and child maintenance under Section 113 and Section 68 of the Women's Charter, they work from the numbers you declare. Those numbers live in the monthly expenditure section of your Affidavit of Assets and Means — Form 220 for the simplified track, or Form 237/238 for contested cases. Understate your expenses, and you lock in a maintenance amount that doesn't cover your real costs. Overstate them, and the judge draws an adverse inference about your credibility. Getting the budget right is not a financial planning exercise — it's a legal strategy decision.

What the Expenditure Section Requires

The AAM asks for a detailed breakdown of your monthly spending, covering both personal expenses and children's expenses. The court expects line items, not round numbers. Typical categories include:

Personal expenses: rent or mortgage instalments, utilities (SP Group bills), groceries, transport (car loan, petrol, road tax, insurance, or public transport), mobile and internet, personal insurance premiums, medical and dental costs, clothing, personal grooming, and dining out.

Children's expenses: school fees and enrichment classes, school uniforms and books, childcare or domestic helper salary and levy, medical and dental, transport to school, pocket money, and activity fees.

Household costs: property tax, town council fees, condominium maintenance charges, cleaning supplies, and home repairs.

The court expects these figures to reflect your actual spending during the marriage or your reasonable needs post-divorce — not aspirational lifestyle costs. Judges look at your declared income against your declared expenses. If a spouse earning S$4,000 a month lists S$8,000 in personal expenses with no explanation, the numbers hurt more than they help.

How to Build the Budget Accurately

Start from your bank and credit card statements — the same 12 months of statements you're already gathering for the AAM. For each month, categorise every transaction. Then average. The averages are your evidence.

For expenses you pay in cash (hawker meals, children's pocket money, market groceries), keep a spending log for one or two months. The court knows some household spending is cash-based, but you need a reasonable basis for the figure you declare.

For irregular expenses — annual insurance premiums, road tax, school registration fees — divide the annual cost by 12 and include it as a monthly average. The court expects you to account for these recurring obligations even if they don't hit your account every month.

Common Mistakes That Weaken Your Case

Rounding too aggressively. A budget where every line ends in zero looks fabricated. The judge has seen hundreds of affidavits — they know real grocery spending doesn't land at exactly S$500 every month.

Forgetting the helper. If you employ a domestic helper, the total cost isn't just salary. Include the monthly levy (S$300 for non-concessionary), insurance, agency fees amortised over the contract, food, and off-day replacements.

Omitting CPF deductions. Your declared income should match your payslip, but your budget should reflect take-home pay after CPF deductions. If you're showing S$6,000 gross income but budgeting against S$6,000 in spending power, you've forgotten that employee CPF contributions are deducted before you see a dollar.

Underestimating children's costs. Enrichment classes, tutoring, and school-related expenses add up faster than most parents track. Pull the actual receipts. A parent claiming S$200 per month for a primary school child when enrichment alone costs S$600 will get challenged.

How the Budget Feeds Into Maintenance Calculations

The court uses your declared monthly expenses as one input in the maintenance decision, alongside your income, your spouse's income, the standard of living during the marriage, and each party's earning capacity. For child maintenance specifically, the court apportions responsibility based on the parents' respective earning capacities and the child's reasonable expenses.

If you're the parent seeking maintenance, your declared budget is the ceiling of what you're asking for. If you're the parent likely to pay, your declared budget establishes your own financial needs — and the surplus between your income and your needs is what the court considers available for maintenance payments.
