What this form asks for

The AI fills all of it, from your answers or your documents.

Florida Form 12.902(i) is a sworn legal statement used to corroborate the residency requirement in a dissolution of marriage case. To get a divorce in Florida, one party must have lived in the state for at least six months, and this form allows a third-party witness to attest to that fact under oath. Today, this form can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

12 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Required Case Identification Fields

Verifies that the 'Judicial Circuit', 'County', 'Case No.', 'Petitioner', and 'Respondent' fields are all filled. These fields are critical for correctly identifying the legal case to which this affidavit pertains. Missing information will result in the clerk rejecting the document for being improperly filed.

Known Person Matches a Party

Ensures the name of the person the witness has known, '{name}', matches either the 'Petitioner' or 'Respondent' name in the case caption. This affidavit's purpose is to corroborate the residency of a party to the case. If the name does not match either party, the affidavit is irrelevant and legally ineffective for this proceeding.

Petition Filing Date Validation

Validates that the 'petition in this action was filed on {date}' is a valid, non-future date in a recognized format (e.g., MM/DD/YYYY). This date is the legal anchor for the six-month residency requirement. An invalid, future, or improperly formatted date would render the affidavit logically flawed and subject to rejection.

Residency Period Corroboration Logic

Checks that the '{approximate date}' the witness has known the party is at least six months prior to the 'petition... was filed on {date}'. This is the core purpose of the affidavit, as it proves the witness's capacity to testify to the required residency period. If the duration is less than six months, the affidavit fails to meet the statutory requirement for corroborating residency.

Witness Name Consistency

Ensures the '{full legal name}' of the witness in the affidavit body is identical to the 'Printed Name' in the signature block. This consistency is crucial for verifying the identity of the affiant (the corroborating witness). A mismatch could invalidate the affidavit or raise questions about its authenticity during legal review.

Witness Contact Information Completeness

Verifies that the witness's 'Printed Name', 'Address', 'City, State, Zip', and 'Telephone Number' are all provided. This information is required to identify and potentially contact the witness for verification or further testimony. Incomplete information may lead to the affidavit being questioned or rejected by the court.

Common Mistakes in Completing Form 12.902(i)

The ones the AI is built to catch.

Signing the Affidavit Without a Notary Present
Witnesses often sign the form at home before taking it to a notary, misunderstanding the process. An affidavit must be signed in the physical presence of the notary public or deputy clerk, who must witness the act of signing. A pre-signed document cannot be properly notarized, rendering the affidavit invalid and causing the court to reject it, which delays the divorce proceedings.
Entering an Incorrect Petition Filing Date
The witness may guess or not know the exact date the Petition for Dissolution of Marriage was filed with the court. This date is the critical reference point for the six-month residency requirement, and an incorrect date makes the entire sworn statement legally unsound. To avoid this, the witness must obtain the exact filing date from the petitioner or the court record before completing the form.
Misunderstanding the Six-Month Residency Period
A witness might confirm the party has lived in Florida for six months, but not for the specific period 'immediately prior to the date of filing of the petition.' This mistake happens when the witness bases their knowledge on the current date, not the legally relevant timeframe. This error can jeopardize the court's jurisdiction over the case, potentially leading to dismissal.
Incomplete or Incorrect Case Caption Information
People frequently miscopy the Judicial Circuit, County, Case Number, or Division from the main divorce filings. Any error in this top section can lead to the affidavit being misfiled by the clerk's office or not being associated with the correct case. To prevent this, carefully copy all information exactly as it appears on the Petition for Dissolution of Marriage.
Mismatching Names of Parties and Witness
The witness might misspell their own name, or more critically, the name of the party whose residency they are corroborating. The name entered in the phrase 'I have known {name}' must exactly match the Petitioner or Respondent's name in the case caption. Discrepancies create ambiguity and can lead a judge to question the validity of the affidavit.
Submitting a Form with an Incomplete Notary Section
After the witness signs, the notary may forget to check a box indicating how identity was verified ('Personally known' or 'Produced identification') or fail to stamp their commission details clearly. The filer is responsible for ensuring the notary's section is fully and correctly completed before leaving the notary's presence. An incomplete notarization invalidates the affidavit.
Using an Ineligible Corroborating Witness
The form is sometimes filled out by a person who lacks direct, personal knowledge of the party's residency for the required six-month period. For example, a friend who lives out of state and only communicates online is not a suitable witness. This can be challenged by the other party or the court, requiring a new, valid affidavit and causing delays.
Forgetting to Serve a Copy on the Other Party
Filers often assume that filing the original document with the court clerk is the only step required. However, the instructions mandate that a copy of the completed affidavit must be sent to the other party in the case. Failure to provide this 'service' is a procedural error that can delay hearings or lead to motions from the opposing side.
Illegible Handwriting and Unprofessional Formatting
Court forms are often filled out by hand with messy or illegible writing, especially since many are distributed as non-fillable PDFs. This can cause the clerk to misinterpret names, dates, or case numbers, leading to filing errors or rejection of the document. Using a tool like Instafill.ai can convert flat PDFs into fillable forms and populate them with clear, typed text to prevent such issues.
Omitting the Nonlawyer Preparer's Information
If a nonlawyer (like a paralegal) assists in filling out the form, they are legally required to complete the section at the bottom with their name, business, and contact information. People often overlook this section, either because they don't realize it's required or the preparer forgets. This omission can have legal consequences for the preparer and may cause the court to scrutinize the document more closely.

What is the purpose of the Affidavit of Corroborating Witness form?

Who needs to fill out and sign this affidavit?
A 'corroborating witness' must complete and sign this form. This must be someone other than the spouses involved in the divorce who has personal knowledge of the party's residency in Florida.
Do I have to use this form to prove residency for my divorce?
No, this form is one of several options. You can also prove residency with a valid Florida driver’s license, Florida identification card, or voter’s registration card, provided it was issued at least six months before the divorce petition was filed.
Who is eligible to be a corroborating witness?
Your witness can be any adult, such as a friend, neighbor, or coworker, who is not your spouse. The key requirement is that they have direct, personal knowledge that you have lived in Florida for the necessary six-month period.
Does the witness's signature need to be notarized?
Yes, this is a sworn affidavit, so the witness must sign it in the physical presence of a notary public or a deputy clerk. The official will then complete their section to certify the signature.

What date should be entered for 'the petition in this action was filed on'?
This refers to the official date that the initial Petition for Dissolution of Marriage was filed with the clerk of court. This date is typically stamped on the first page of the petition documents.
Am I required to file this form electronically?
While e-filing is common, self-represented litigants in Florida are not required to e-file and may submit the physical paper form to the clerk's office. If you do choose to e-file, you must follow the court's specific rules and procedures.
