How to Use a Business Records Affidavit Under Rule 803(6)

A business records affidavit is a sworn statement from someone inside a company confirming that attached documents are genuine records kept in the ordinary course of that company’s operations, and it lets those records go into evidence without pulling a live witness into court. Under Federal Rule of Evidence 803(6), the affidavit does the foundational work a custodian would otherwise do from the witness stand. Get it right and bank statements, invoices, medical bills, or personnel files come in with a signature and a notice. Get it wrong and the records get struck, sometimes on the eve of trial.

The Five Elements the Affidavit Must Cover

Rule 803(6) admits a record of an act, event, condition, opinion, or diagnosis when five conditions are met:¹

The record was made at or near the time of the event by someone with knowledge, or from information passed along by someone with knowledge.
The record was kept as part of a regularly conducted business activity, whether or not the organization operates for profit.
Making this type of record was a standard practice of the organization.
A custodian, another qualified witness, or a written certification establishes the first three points.
The opposing party does not show that the source of information or the way the record was prepared makes it untrustworthy.

Every affidavit needs to speak to the first three in specific language, because the fifth element is where most fights happen. Records that look like they were generated with an eye toward the lawsuit, rather than routine operations, invite trustworthiness objections even when the paperwork is otherwise clean.

Who Should Sign the Affidavit

The affiant does not need to have personally created the record or seen the underlying transaction. They need to be able to explain how the organization’s record-keeping system works: how data enters the system, when entries are made, who is responsible for accuracy, and how records are stored and retrieved.

In practice, a department manager or a dedicated records clerk is usually the right pick. A CEO oversees the whole company but often cannot describe the accounting software or say how quickly after a transaction an entry is logged. Courts care about someone who understands the mechanics, not someone at the top of the org chart.

When records live on a third-party cloud platform, the analysis gets messier. The Federal Rules do not define “qualified witness” with precision, and the Advisory Committee Notes favor flexibility. An employee at the originating company who understands the workflow is generally safer than a technician at the hosting vendor who only knows the storage infrastructure.¹

What to Put in the Affidavit

Vague assertions that records were “kept in the ordinary course of business” without concrete detail invite objections. A workable affidavit addresses each of the following in plain terms:

The affiant’s full name, job title, and familiarity with the record-keeping system.
A precise description of each attached document, including date ranges and document types. “Account statements for Account No. 4455 from January through June 2025” beats “certain bank records.”
A statement that each record was made at or near the time of the event, by or from information provided by someone with direct knowledge.
Confirmation that the records were kept as part of a regularly conducted activity of the organization.
An assertion that making this type of record is a standard practice, not something done only for this case.

Specificity matters. If a medical bill is being introduced, the affidavit should tie the bill to the provider’s standard billing cycle and explain that charges are entered by billing staff who receive information from the treating clinicians. That kind of detail makes it hard for the other side to argue the record was cooked up for litigation.

Fill every field. Missing the affiant’s title, omitting the date range, or using a business entity name that does not match official filings all create openings for objections. Standardized forms on local court websites give you a template, but boilerplate alone defeats the purpose.

Sworn Affidavit, Unsworn Declaration, or Rule 902(11) Certification

Rule 803(6)(D) lets you establish the foundation through live testimony or through a written certification that satisfies Rule 902(11) for domestic records or Rule 902(12) for foreign records.² The certification route is usually cheaper and faster because no one has to travel to a courthouse just to say “yes, we keep records this way.”

A certification under Rule 902(11) must come from the custodian or another qualified person, comply with a federal statute or Supreme Court rule, and meet the same substantive requirements as an affidavit. The Advisory Committee Notes confirm that a declaration satisfying 28 U.S.C. § 1746 meets the certification requirement.²

Notarization is often assumed to be mandatory. In federal proceedings it usually is not. Under 28 U.S.C. § 1746, any matter federal law requires to be supported by a sworn statement can instead be supported by an unsworn written declaration signed under penalty of perjury.³ The declaration must be dated, signed, and include language substantially like: “I declare under penalty of perjury that the foregoing is true and correct.” Rule 56 explicitly recognizes this alternative for summary judgment motions.⁴ State courts vary on whether they accept unsworn declarations, so check local rules before skipping the notary in a state proceeding.

When you do use a notary, fees are set by state law. They run from as low as $2 per signature in a few states to $25 in others, with most states falling between $5 and $15, and about a dozen states set no maximum.⁵ Remote online notarization is authorized in most states.

Authenticating Electronic Records

Records today are overwhelmingly digital, which adds a layer of authentication on top of the hearsay analysis. Rule 902(13) lets records generated by an electronic process or system be self-authenticated through a certification from a qualified person showing the system produces accurate results. Rule 902(14) does the same for data copied from an electronic device, storage medium, or file.²

The 902(13) or 902(14) certification only establishes authenticity. It does not solve hearsay. A spreadsheet exported from an accounting system still needs a separate 803(6) foundation. The two certifications work in tandem but are legally distinct, and both carry the same notice requirements as Rule 902(11).

Serving the Affidavit and Meeting the Notice Requirement

After the affidavit is signed, the underlying records get attached as labeled exhibits, typically using sequential letters or numbers. The complete package is then served on the opposing party.

Federal rules require “reasonable written notice” before trial or hearing and an opportunity for the opposing side to inspect the record and the certification. The rule does not fix a specific number of days, and state deadlines vary. Miss the applicable deadline and you may end up producing a live witness after all, which is exactly what the affidavit was supposed to avoid.

If no objection arrives within the designated window, courts routinely admit the records without further testimony. That is the efficiency payoff. But counting on silent acceptance is a gamble when the affidavit has weak spots, because a sharp opposing attorney will hold the objection for the last possible moment.

Statements Inside the Records That Came From Outsiders

A business record sometimes contains statements made by people outside the organization. A hospital intake form might record a patient’s description of how an injury happened. The form qualifies as a business record, but the patient’s statement inside it is a separate layer of hearsay, because the patient was not acting in the routine of the hospital’s business when they spoke.

Rule 805 allows hearsay within hearsay only if each layer independently qualifies under its own exception.⁶ The hospital record clears 803(6), but the patient’s statement needs a separate justification. A description of symptoms given to help with diagnosis may fall under the exception for statements made for medical treatment. Casual conversation probably does not, and the embedded statement gets excluded even though the surrounding record comes in.

Before you file the affidavit, read the attached documents with this in mind. Ask whether they contain statements from non-employees or third parties, because opposing counsel will.

Using the Absence of a Record

Business records affidavits are not limited to proving that something happened. Under Rule 803(7), the absence of an entry can prove that an event did not occur or that a matter does not exist.¹ If a company logs every customer complaint and no complaint from a particular customer appears in the system, that absence is itself admissible.

The foundation looks like Rule 803(6): the affiant must establish that the organization regularly kept records for that type of matter and that the absence is not the product of unreliable record-keeping. Useful tool for defendants trying to show an alleged event never happened, provided the system is robust enough to support the inference.

How the Other Side Will Attack the Affidavit

The most productive ground for challenge is the trustworthiness element in Rule 803(6)(E). Even when the first four foundational requirements are met, the opposing party can argue that the source of information or the method of preparation makes the record unreliable. The burden sits on the opponent to affirmatively show a lack of trustworthiness, not merely assert it.¹

Common attack lines:

Documents created with an express eye toward trial rather than normal operations undermine the core rationale of the exception.
If the underlying data entered into the system was not verified for accuracy, the reliability of the entire record is questionable.
When the affiant cannot explain the record-keeping process in meaningful detail, the foundation collapses. An affiant who does not know what software generated the records, or how quickly entries were made after the underlying event, is vulnerable on cross.
Ambiguous document descriptions, wrong entity names, or gaps in the date range all support a motion to strike.

Objections are typically raised within a deadline set by local rules or the scheduling order. If the objection succeeds, the records are excluded, which can be devastating when the claim or defense rests on them.

The Confrontation Clause Limit in Criminal Cases

Most of the above applies cleanly in civil litigation. Criminal cases carry a constitutional wrinkle: the Sixth Amendment’s Confrontation Clause guarantees a defendant the right to confront the witnesses against them.

In Melendez-Diaz v. Massachusetts, the Supreme Court held that certificates prepared by forensic analysts specifically for use at trial were testimonial statements, and admitting them without giving the defendant a chance to cross-examine violated the Confrontation Clause.⁷ The Court drew the line this way: records created for the administration of an organization’s affairs are generally not testimonial, but records or certifications prepared to establish a fact at trial are, regardless of whether they might otherwise fit a hearsay exception.

A routine invoice generated during normal operations will likely survive a Confrontation Clause challenge. A lab report or certification generated because law enforcement asked for it probably will not. Prosecutors relying on business records affidavits should evaluate whether the records exist for operational reasons or were compiled in anticipation of prosecution. If it is the latter, the custodian or the person who created the record may need to testify live.

Perjury Exposure for the Signer

Signing a business records affidavit is not a formality. A custodian who knowingly makes false statements in a sworn affidavit faces prosecution for perjury under 18 U.S.C. § 1621, which carries up to five years in federal prison, a fine, or both.⁸ The statute reaches sworn statements and unsworn declarations under 28 U.S.C. § 1746 equally, so the unsworn route offers no reduction in exposure.

Beyond criminal liability, a false affidavit can bring court sanctions, dismissal of claims or defenses that relied on the fabricated records, and adverse inferences against the party that submitted them. The exception exists because organizations depend on the accuracy of their own files, and courts protect that assumption aggressively.
