Child Support Modification Checklist

Family Law Attorney and Client Resource

Prepare a child support modification case with a document checklist for family law attorneys and parents. Gather the current support order and payment history, both parties' income records, health-insurance and childcare costs, the child's residence and parenting-time records, and evidence of a substantial change (job loss, new income, emancipation, or medical needs) so you can complete worksheets and file a complete motion or stipulated modification. This is not legal advice; guidelines, lookback periods, and what counts as a material change vary by state—confirm current rules before filing.

Frequently Asked Questions

What usually qualifies as a change in circumstances?
Common examples include a lasting change in either parent's income, a change in parenting time, loss of health coverage, new childcare or medical costs, or a child aging out. States set their own thresholds (sometimes a percentage change in the guideline amount). Confirm the local standard before filing.
Which income documents should I collect?
Recent pay stubs, the last two years of tax returns and W-2s or 1099s, profit-and-loss statements for self-employment, unemployment or disability award letters, and proof of bonuses or overtime. If the other party's income is unknown, note what you have and what must be obtained in discovery.
Do I need the original support order?
Yes. The court needs the current order, any prior modifications, and a payment history (state disbursement printout or cancelled payments). Without the existing terms you cannot show what should change or compute arrears versus prospective support.
Is this checklist legal advice?
No. Support guidelines, imputation rules, and modification procedures differ by state. Use the list to organize documents, then have licensed counsel apply current local rules to the facts.

Checklist

Existing Orders

Current child support order and any later modification orders
Required

Include the full signed order, worksheet attachments, and case number. Note the court and county.

Support payment history from the state disbursement unit or equivalent
Required

Print a recent ledger showing payments, arrears, and fees. Bank records help if there is no SDU account.

Income

Moving party's income records: pay stubs, tax returns, and W-2 or 1099 forms
Required

Typically last 3 months of pay stubs and 2 years of returns. Self-employed parties need a current profit-and-loss statement.

Other parent's known income records or last disclosed financial affidavit
Required

Use prior affidavits, tax returns produced in the original case, or public wage information if already obtained lawfully.

Expenses

Health insurance premiums and work-related childcare costs for the children
Required

Premium attributable to the children, not the whole family plan if it can be broken out. Receipts or invoices for daycare.

Custody

Current parenting-time schedule or custody order affecting overnight counts
Required

Overnight counts often drive guideline deviations. Include a calendar if the written order is outdated.

Change in Circumstances

Evidence of the change: termination letter, new offer, disability award, or medical bills
Required

Tie each exhibit to the date the change began. Courts look for a continuing change, not a one-month dip.

Children

Each child's name, date of birth, residence, and school enrollment or emancipation status
Required

Needed for guideline worksheets and to drop a child who has aged out where the order allows.
