All Borough Group Med. Supply, Inc. v Geico Ins. Co., 2013 NY Slip Op 23262 (App. Term 2d Dept. 2013)

“At the outset, we note that plaintiff was not required to lay a CPLR 4518 (a) foundation for the assignment of benefits form. An assignment of benefits is not hearsay; like a contract, it has independent legal significance and need only be authenticated to be admisible (sic)(see Kepner-Tregoe, Inc. v Leadership Software, Inc., 12 F3d 527, 540 ; see also Beal-Medea Prods., Inc. v NY Cent. Mut. Fire Ins. Co., 36 Misc 3d 135, 2012 NY Slip Op 51347 ). However, plaintiff was attempting to use the delivery receipt and claim form to prove the transactions recorded therein, and so was required to lay a CPLR 4518 (a) foundation for those records.”

“If a record is made in the regular course of business, it is the regular course of business to make the record, and the record is made at or about the time of the event being recorded, the record can be admitted into evidence pursuant to the CPLR 4518 (a) business records hearsay exception.”

“A review of the evidence adduced at trial shows that plaintiff’s witness was employed by plaintiff prior to, during, and after the time that defendant had provided the supplies to plaintiff. The witness testified he and another person who was no longer employed by plaintiff had generated all of plaintiff’s claim forms, and that his father, who was the owner of plaintiff, had generated the delivery receipts. The witness also testified, albeit inartfully, that he was familiar with plaintiff’s office routine and that plaintiff’s delivery receipts and claim forms were routinely and contemporaneously made in the course of plaintiff’s business, and that it is plaintiff’s regular business practice to make such records.”

“In addition, CPLR 4518 (a) provides that a witness’s lack of personal knowledge affects the weight of the record, not the admissibility of the record.”

So consider this a basic evidence lesson from the Appellate Term.


Legal Update (February 2026): Since this 2013 post, CPLR 4518(a) business records requirements and foundations may have been refined through subsequent case law interpretations and court rule amendments. Practitioners should verify current evidentiary standards for business records authentication, particularly regarding foundation requirements for medical supply billing records and assignments of benefits in no-fault insurance cases.

Legal Context

Why This Matters for Your Case

New York law is among the most complex and nuanced in the country, with distinct procedural rules, substantive doctrines, and court systems that differ significantly from other jurisdictions. The Civil Practice Law and Rules (CPLR) governs every stage of civil litigation, from service of process through trial and appeal. The Appellate Division, Appellate Term, and Court of Appeals create a rich and ever-evolving body of case law that practitioners must follow.

Attorney Jason Tenenbaum has practiced across these areas for over 24 years, writing more than 1,000 appellate briefs and publishing over 2,353 legal articles that attorneys and clients rely on for guidance. The analysis in this article reflects real courtroom experience — from motion practice in Civil Court and Supreme Court to oral arguments before the Appellate Division — and a deep understanding of how New York courts actually apply the law in practice.

About This Topic

Business Records & Documentary Evidence in New York

The business records exception to the hearsay rule is one of the most important evidentiary foundations in New York litigation. Establishing that a document qualifies as a business record under CPLR 4518 requires showing it was made in the regular course of business, at or near the time of the event, and that it was the regular practice to create such records. In no-fault and personal injury cases, disputes over business records arise constantly — from claim files and medical records to billing documents and mailing logs.

New York law varies by jurisdiction — court decisions in one Appellate Division department may not be followed in another, and local court rules in Nassau County Supreme Court differ from those in Suffolk County Supreme Court, Kings County Civil Court, or Queens County Supreme Court. The Appellate Division, Second Department (which covers Long Island, Brooklyn, Queens, and Staten Island) and the Appellate Term (which hears appeals from lower courts) each have distinct procedural requirements and precedents that affect litigation strategy.
