Evidence Center · Proving Income
Every support case is an income-proof case.
Child support runs on a guideline the statute makes presumptive — which means the real fight is almost always the INPUTS: what each parent actually earns. This page walks how income is proved, against the authorities this platform already holds verbatim: the documents the disclosure rule compels, the business-records lane bank and payroll records ride, the certification that can replace a live custodian, the summary rule for years of statements, and the other party's own sworn words.
The stake — § 61.30
“presumptively establishes the amount the trier of fact must order as child support for a minor child, or a child who is dependent in fact and between the ages of 18 and 19 and who is still in high school and is performing in good faith with a reasonable expectation of graduation before he or she reach”Presumptive means the guideline number carries unless the court makes findings to vary — so the income figures that FEED the guideline are where cases are commonly won and lost. The § 61.30 calculator shows the arithmetic; this page is about proving the inputs.
Start with what the rules already compel
Rule 12.285 obligates both sides to produce the income classes — affidavits, tax returns, pay records, account statements — before anyone lifts a discovery tool. The crosswalk maps every class to what it proves; the Procedure Matrix maps the tools when the floor is not honored. And in enforcement and contempt, Rule 12.287 adds its own on-request affidavit:
“serve upon any other party a written request to serve a financial affidavit if the other party’s financial circumstances are relevant in the proceeding.”The lane the records ride — § 90.803(6) + § 90.902(11)
Bank statements, payroll runs, and employer records are classic records of regularly conducted business activity — and the statutes pair the hearsay lane with a certification route that can stand in for a live records custodian:
“kept in the course of a regularly conducted business activity and if it was the regular practice of that business activity to make such memorandum, report, record, or data compilation, all as shown by the testimony of the custodian or other qualified witness, or as shown by a cert”“accompanied by a certification or declaration from the custodian of the records or another qualified person certifying or declaring that the record: (a) Was made at or near the time of the occurrence of the matters set forth by, or from information transmitted by, a person having knowledge of those”The pairing is the practice point: § 90.803(6) itself names the certification that complies with § 90.902(11) as one way the foundation is shown. Getting the certification, serving the notice, and meeting the timing is a campaign counsel commonly runs — the bank & financial records foundation and the wage records foundation carry the checklists.
The volume, the admissions, the declarations
“voluminous writings, recordings, or photographs, a party may present them in the form of a chart, summary, or calculation by calling a qualified witness.”“without accounting for the nonproduction of the original.”“Under penalties of perjury, I declare that I have read the foregoing [document] and that the facts stated in it are true," followed by the signature of the person making the declaration, except when a verification on information or belief is perm”- · Years of statements ride § 90.956's summary rule — with its notice and make-available duties, walked on the Article X page.
- · The other party's own words — deposition testimony, written admissions under Rule 12.370 — can prove contents without the original (§ 90.957), and an admission about income is commonly the cleanest proof there is.
- · Financial affidavits are sworn: § 92.525's verification is what separates a filed affidavit from a letter.
Work the gap map
In the Evidence Organizer, add the income facts you need to prove — "overtime in 2025," "the cash side of the business" — and link the items you hold. A fact with nothing linked is your gathering list, in your own words. What any of it establishes is the court's call on the day; assembling it is yours, and independent attorney review is the route for judgment.
