AFFIDAVIT / DECLARATION — FILL-IN TEMPLATE (NOT LEGAL ADVICE · NOT A CERTIFIED REPORT) *** READ FIRST *** This document is a fill-in template. It is not legal advice, not a certified forensic report, and not a sworn statement until a qualified person reviews, completes, and adopts it. It must be reviewed and adapted by qualified counsel and, where applicable, completed and signed by a qualified examiner with personal knowledge before any legal, regulatory, or evidentiary use. Nothing in this template asserts that any tool output is admissible or certified — whether evidence may be admitted is decided by counsel and the court under the rules of the relevant jurisdiction, not by this template and not by fatcousin labs Inc. See the site disclaimer at https://fatcousin.com/disclaimer. ---------------------------------------------------------------------- [caption / court / matter — to be completed by counsel] 1. DECLARANT I, [examiner name], declare as follows. I make this declaration based on my own examination and personal knowledge. Where a statement is made on information and belief, I identify it as such. 2. QUALIFICATIONS [examiner qualifications — education, certifications, relevant experience, prior testimony, and the basis for competence to perform this examination] 3. SCOPE OF EXAMINATION [describe the scope of examination you were asked to perform] 4. EVIDENCE EXAMINED [describe each item examined: file name(s), source, how you came to hold it, input sha-256 digest(s), and dates. This template does not cover how the evidence was collected or acquired — describe that separately, on your own knowledge.] 5. LOCAL-ONLY EXECUTION The analysis described below was performed locally in the examiner's browser on a workstation under the examiner's control. No evidence was transmitted to fatcousin labs Inc. or any third party. 6. TOOLS USED [no tools selected — list each tool run, its URL, version, and published bundle sha-256] 7. METHODOLOGY & EVIDENTIARY REFERENCES The following references are provided for counsel's review. They are general references, not a representation that any specific output satisfies them in this matter: FRE 901(a) — authentication requirement (US (Federal) · authentication): The proponent must produce evidence sufficient to support a finding that the item is what the proponent claims it is. FRE 901(b)(1) — testimony of a witness with knowledge (US (Federal) · authentication): A witness with personal knowledge that an item is what it is claimed to be may authenticate it by testimony. FRE 901(b)(9) — process or system authentication (US (Federal) · authentication): Evidence describing a process or system and showing it produces an accurate result may authenticate a result obtained from that process or system. FRE 104(a) — preliminary questions · court as gatekeeper (US (Federal) · authentication): The court decides preliminary questions of admissibility — including authentication — by a preponderance of the evidence. The court is not bound by evidence rules when so deciding. FRE 902(11) — business records · certification (US (Federal) · self-authentication): Domestic records of a regularly conducted activity may be self-authenticating when accompanied by a certification meeting Rule 902(11) requirements. FRE 902(13) — certified records generated by an electronic process (US (Federal) · self-authentication): A record generated by an electronic process or system may be self-authenticating when certified as accurate by a qualified person familiar with the process. FRE 902(14) — certified data copied from an electronic device or storage medium (US (Federal) · self-authentication): Data copied from an electronic device or storage medium may be self-authenticating when certified as a true and accurate copy by a qualified person using a verified process. FRE 1001 — definitions · writing & original (US (Federal) · best-evidence): Defines 'writing' and 'original' for the best-evidence rule — including prints and other duplicates of an original. FRE 1002 — requirement of the original (US (Federal) · best-evidence): To prove the content of a writing, recording, or photograph, the original is required unless an exception applies. FRE 1003 — admissibility of duplicates (US (Federal) · best-evidence): A duplicate is admissible to the same extent as an original unless a genuine question is raised about the duplicate's authenticity or it would be unfair to admit the duplicate. FRE 1004 — admissibility of other evidence of content (US (Federal) · best-evidence): An original is not required if all originals are lost or destroyed without bad faith, cannot be obtained by any available judicial process, or is in the opponent's possession and not obtainable. FRE 1006 — summaries to prove content (US (Federal) · best-evidence): The contents of voluminous writings may be presented in summary form if the originals are admissible and available for examination. FRE 702 — expert testimony · Daubert gate (US (Federal) · expert reliability): Expert testimony is admissible if the expert is qualified and the testimony is based on sufficient facts, reliable principles, and reliable application — the rule courts apply after Daubert v. Merrell Dow. 8. FINDINGS SUMMARY [summarize findings in your own words. State outputs as investigative leads, note corroboration performed, and identify limitations and anything you could not determine.] 9. LIMITATIONS - Tool outputs are investigative leads, not verdicts. Every finding must be corroborated against primary sources before anyone relies on it. - This template documents the analysis phase only — work performed on exports the examiner already lawfully holds. It does not describe, and does not substitute for, evidence collection, acquisition, or seizure, which occur upstream and outside the scope of these tools. - All processing described here ran locally in the examiner's browser; no evidence was transmitted to fatcousin labs Inc. or any third party. - Independent verification of every result is required before any legal, financial, medical, safety, or evidentiary use. - Any bundle SHA-256 values below identify the published tool code that was run and, when verified against the signed provenance registry at https://fatcousin.com/provenance, may assist in demonstrating the integrity and authenticity of that tool code. They do not independently establish the authenticity, integrity, chain of custody, or provenance of the underlying evidence. 10. LIMITS OF THIS TEMPLATE This document is a fill-in template. It is not legal advice, not a certified forensic report, and not a sworn statement until a qualified person reviews, completes, and adopts it. It must be reviewed and adapted by qualified counsel and, where applicable, completed and signed by a qualified examiner with personal knowledge before any legal, regulatory, or evidentiary use. Nothing in this template asserts that any tool output is admissible or certified — whether evidence may be admitted is decided by counsel and the court under the rules of the relevant jurisdiction, not by this template and not by fatcousin labs Inc. See the site disclaimer at https://fatcousin.com/disclaimer. ---------------------------------------------------------------------- I declare (or certify, verify, or state) under penalty of perjury, only after completion and review and where my jurisdiction's rules so provide, that the foregoing is true and correct. Executed on: _________________________ (prepared 2026-06-03) Signature: _________________________ Printed name: [examiner name] // Prepared with the fatcousin affidavit/declaration template builder · local-only · files never leave the device · NON-AUTHORITATIVE TEMPLATE — requires qualified review before use.
how to use this responsibly
- every blank renders as a bracketed prompt (e.g.
[examiner name]). nothing is invented for you — a qualified examiner with personal knowledge completes each field. - the methodology references are general references for counsel's review, not a representation that any output satisfies them in your matter.
- bundle sha-256 values identify the published tool code — verify them yourself at /provenance. they do not establish the integrity of the underlying evidence.
- have qualified counsel review and adapt the draft, and (where applicable) a qualified examiner sign it, before any legal, regulatory, or evidentiary use. whether evidence may be admitted is decided by counsel and the court, not by fatcousin.
