Understanding Evidence Rules: Why Affidavits Cannot Be Used at Trial
In the complex landscape of New York litigation, understanding the rules of evidence is crucial for every attorney and legal professional. One fundamental principle that often catches inexperienced practitioners off guard is the inadmissibility of affidavits during trial proceedings. While affidavits serve important purposes in pre-trial motions and discovery, they face strict limitations when it comes to actual courtroom testimony.

Matter of New York Rezulin Prods. Liab. Litig. v Pfizer, Inc., 2009 NY Slip Op 07496 (1st Dept. 2009)
“There is no basis to disturb the court’s determination in favor of Duffy ( see Thoreson v. Penthouse Intl., 80 N.Y.2d 490, 495, 591 N.Y.S.2d 978, 606 N.E.2d 1369 ). At the hearing, Girardi called no witnesses on its own behalf to contradict the testimony of Duffy’s witnesses as to the existence of an oral one-third fee arrangement between the two firms. The court properly declined to consider affidavits by a witness who was not available for cross-examination in court ( see Seinfeld v. Robinson, 300 A.D.2d 208, 755 N.Y.S.2d 69 ).
I did not post this case not for its precedential value. It is obvious. I posted this case because if you recall at the CLE in Brooklyn that we gave, I stated that the reason you as a practitioner should make summary judgment motions is because you cannot cross-examine the underlying affidavits that support the motion. However, should you be forced to go to trial, you will not be able to rely on an affidavit because it is not subject to cross-examination. See, id.
The Strategic Implications for New York and Long Island Practitioners
For attorneys practicing in New York City and Long Island, this fundamental evidence rule has profound strategic implications. The inability to use affidavits at trial creates a clear dividing line between pre-trial and trial strategy that every practitioner must navigate carefully.
Pre-Trial Motion Practice vs. Trial Strategy
During the pre-trial phase, affidavits serve as powerful tools for summary judgment motions, preliminary injunctions, and various other applications to the court. The opposing party cannot cross-examine the affiant, which gives these sworn statements significant weight in motion practice. This asymmetry creates opportunities for creative advocacy and case resolution before trial.
However, once a case proceeds to trial, the evidentiary landscape changes dramatically. The right to confrontation becomes paramount, and courts strictly enforce the rule that witnesses must be available for cross-examination. This transition requires attorneys to completely reassess their evidence and witness strategies.
The Cross-Examination Requirement in New York Courts
New York’s adherence to the confrontation principle reflects broader constitutional and procedural due process protections. When a case reaches trial, whether in Nassau County, Suffolk County, or Manhattan, judges consistently apply this rule to ensure fairness and reliability in fact-finding.
The requirement serves multiple purposes:
– It allows opposing counsel to test the credibility of witnesses
– It provides the court with opportunities to assess demeanor and truthfulness
– It ensures that all evidence is subject to the adversarial process
– It prevents parties from avoiding difficult cross-examination by relying on written statements
Practical Applications for Long Island and NYC Personal Injury Cases
In personal injury practice throughout Long Island and New York City, this rule creates specific challenges and opportunities that attorneys must address from the outset of representation.
Medical Records and Expert Testimony
Personal injury attorneys often rely heavily on medical records and expert opinions during settlement negotiations and motion practice. However, when cases proceed to trial, these same attorneys must ensure that treating physicians and expert witnesses are available to testify in person. Affidavits from medical professionals, regardless of their credentials or the strength of their opinions, cannot substitute for live testimony.
Accident Reconstruction and Witness Statements
Motor vehicle accidents, premises liability cases, and construction accidents frequently involve witness statements and accident reconstruction reports that are initially prepared in affidavit form. While these documents may support pre-trial motions effectively, trial preparation must include arrangements for live witness testimony. This often means additional costs and scheduling challenges that must be factored into case budgets and strategy.
Frequently Asked Questions
Can affidavits ever be used as evidence during a New York trial?
Generally no, affidavits cannot be used as substantive evidence during trial because they violate the confrontation clause and rules requiring cross-examination. There are very limited exceptions for specific procedural matters, but these do not apply to witness testimony about the facts of a case.
What happens if a witness becomes unavailable between the motion phase and trial?
If a witness becomes unavailable due to death, serious illness, or other compelling circumstances, courts may consider alternative forms of testimony such as depositions taken with opposing counsel present. However, simple unavailability or inconvenience will not excuse the requirement for live testimony.
How should attorneys prepare differently for motion practice versus trial?
Motion practice can rely on affidavits, expert reports, and documentary evidence that may not be admissible at trial. Trial preparation must focus on securing live witnesses who can be cross-examined, ensuring proper foundation for exhibits, and preparing for the rules of evidence that govern courtroom proceedings.
Does this rule apply differently in federal court versus New York state court?
Both federal and New York state courts follow similar principles regarding the inadmissibility of affidavits as substantive evidence at trial. The Federal Rules of Evidence and New York’s evidence rules both prioritize live testimony subject to cross-examination.
What are the consequences for attorneys who attempt to rely on affidavits during trial?
Courts will exclude affidavits offered as substantive evidence, potentially leaving attorneys without crucial testimony to support their case. This can result in directed verdicts, summary judgment against the attorney’s client, or other adverse rulings that could have been avoided with proper preparation.
Building Your Case Strategy Around This Rule
Understanding the affidavit rule should inform every aspect of case development from initial client consultation through trial preparation. Successful attorneys in New York and Long Island build their practice around this fundamental principle.
Early Case Assessment
During initial case evaluation, attorneys should identify all potential witnesses and assess their availability for trial testimony. This includes not only favorable witnesses but also adverse witnesses who may need to be subpoenaed. The inability to rely on affidavits means that witness cooperation and availability become critical case factors.
Discovery Strategy
Discovery planning should prioritize depositions and other forms of testimony that can be used at trial if witnesses become unavailable. While affidavits may support discovery motions, the ultimate goal should be obtaining admissible evidence for trial use.
