Florida Form 12.902(i): Affidavit of Corroborating Witness

Start with the free official Form 12.902(i)

Florida Courts currently lists Florida Supreme Court Approved Family Law Form 12.902(i), Affidavit of Corroborating Witness, dated February 2018. The official PDF contains four pages: two instruction pages, the one-page affidavit, and a separate page for the nonlawyer-assistance disclosure fields.

What does Form 12.902(i) address?

The instructions describe this affidavit as one way to corroborate Florida residence in a dissolution-of-marriage proceeding. They say the person signing must know that the person named in the affidavit lived in Florida for at least six months before the dissolution petition was filed.

What information appears on Form 12.902(i)?

1. Use the case caption exactly as the court record displays it

The affidavit begins with fields for the judicial circuit, county, case number, division, petitioner, and respondent. Those fields identify the dissolution case; they do not establish residence.

This guide does not determine what should be entered or left for the clerk, correct party designations, choose a county, or decide jurisdiction or venue.

2. Keep the witness and the person whose residence is described separate

The affidavit first asks for the full legal name of the person who is swearing to the statement. It then asks for the name of the person that witness has known and the approximate date the witness began knowing that person.

The instructions describe the affiant as someone other than the person whose residence is being corroborated or that person's spouse. This guide does not select the witness, decide whether a relationship is disqualifying, or determine whether the witness knows enough to sign.

3. Distinguish the petition filing date from other dates

The statement displays a blank for the approximate date the witness began knowing the person and a separate blank for the date the dissolution petition was filed. Its fixed language then refers to the six months immediately before the petition filing date.

4. Read the fixed personal-knowledge statement before signing

The affidavit states that the witness knows from personal knowledge that the named person resided in Florida for at least six months immediately before the petition was filed. The sentence is printed language, not an open narrative for Sun State to write.

A witness should read the complete official sentence and oath. This guide does not explain what legally qualifies as residence or personal knowledge, assess evidence, or modify the government wording.

5. Review the oath and witness contact fields independently

The affidavit warns that the signer is swearing or affirming that the claims are true and that knowingly making a false statement can result in fines, imprisonment, or both. The witness section then displays a date, signature line, printed name, address, city/state/ZIP, and telephone number.

Completing a PDF does not sign it, place anyone under oath, verify a statement, or make the affidavit legally sufficient. Sun State does not sign for the witness or advise anyone to sign.

6. Leave the notarial act to the notary public or deputy clerk

The official instructions say the form should be signed in the presence of a notary public or deputy clerk. The affidavit's notary block displays the Florida county, the date and name for the sworn or affirmed signing, the notary or deputy-clerk line, commissioned-name area, personally-known and produced-identification choices, and identification-type blank.

7. Treat the packet's proof examples as alternatives, not a recommendation

The February 2018 instructions say residence may be corroborated using certain Florida identification or voter-registration records whose issue date satisfies the period stated in the packet, or through testimony or an affidavit from someone other than the person or that person's spouse. Form 12.902(i) is the affidavit method described there.

This guide does not choose among proof methods, decide whether a document is valid, determine which date controls, or state what a court will require in a particular case. Confirm current requirements through official court resources or qualified legal help.

8. Read the 2018 filing and service instructions in current context

The packet says to file the original with the clerk in the county where the petition was filed, keep a copy, and provide a copy to the other party if the affidavit was not served with the initial papers. It also contains 2018 discussions of e-filing, e-service, Forms 12.914 and 12.915, and then-current judicial-administration rules.

Those procedural passages are dated February 2018. Rules, form names, portal procedures, and local requirements can change. Florida Courts' current self-help guidance ↗ says self-represented parties are responsible for current statewide rules, local rules, administrative orders, required documents, and deadlines.

9. Review the separate nonlawyer-assistance page

Page four says that a nonlawyer who helped fill out the form must complete all blanks. It displays a prepared-for choice—affiant, petitioner, or respondent—and fields for the assisting individual, business, address, city, state, ZIP code, and telephone number.

The instructions also say a nonlawyer must provide Form 12.900(a), Disclosure from Nonlawyer, before helping and place the nonlawyer's name, address, and telephone number on the last page of every form the nonlawyer helps complete.

Sun State does not determine residence, select a witness or proof method, evaluate testimony, supply sworn facts, notarize, file, or serve the affidavit.
