 Types of Evidence (Documents) Required In Court for a Felony Case

Evidence is the foundation of any legal case. In felony trials, having the right type of evidence can be the difference between conviction and acquittal. Here, we discuss at least five types of evidence relevant to felony cases:

  • Document 1: Real Evidence – Often referred to as physical evidence, this includes tangible objects like weapons, DNA samples, or fingerprints directly related to the crime.
  • Document 2: Documentary Evidence – Documents that support the facts of the case, such as written contracts, letters, or emails.
  • Document 3: Demonstrative Evidence – Visual aids that assist in explaining or proving a fact, like photographs, videos, diagrams, or charts.
  • Document 4: Testimonial Evidence – Statements made under oath by witnesses. This might be a victim’s account, an eyewitness testimony, or an expert’s opinion on a specific matter.
  • Document 5: Digital Evidence – Information stored or transmitted in digital form, such as computer files, text messages, or social media posts.

How Will This Evidence Make My Felony Case Stronger?

Each type of evidence plays a pivotal role:

Real Evidence

Real evidence pertains to tangible or physical items directly associated with the crime in question. Such evidence stands out for its ability to offer indisputable, concrete proof of an event or action.

Imagine a weapon found at a crime scene imprinted with a suspect’s fingerprints – this is direct evidence linking them to the crime. Another key aspect of real evidence is the chain of custody.

For this evidence to be credible, there must be assurance that it hasn’t been tampered with or compromised. For example, in a homicide case, a bloodied knife containing the defendant’s DNA can massively influence the jury’s verdict.

Documentary Evidence

Documentary evidence consists of written documents utilized to validate or contest a specific claim or argument. Such evidence can prove invaluable in reinforcing verbal claims. For instance, a written threat can corroborate an individual’s claim of being threatened.

Additionally, documents like bank statements or transaction records serve as historical records of events or transactions, pivotal for establishing motives or timelines. In cases of fraud, these records can shed light on deceitful activities.

Demonstrative Evidence

Demonstrative evidence is best understood as visual aids introduced in courtrooms to elucidate or illustrate intricate matters. Such evidence becomes vital when considering that not all jurors might be acquainted with complex or technical subjects. Diagrams, charts, animations, or other visual tools can clarify these subjects, enhancing their comprehensibility.

When paired with witness testimonies, these visual aids can become even more compelling. For instance, in cases involving accidents, a reenacted video can effectively illustrate the sequence of events leading to the accident.

Testimonial Evidence

When witnesses make statements under oath, either during trials or depositions, it is termed testimonial evidence. These statements offer the court firsthand accounts of incidents or expert analyses on particular subjects.

The strength of testimonial evidence often hinges on the credibility of the witnesses. A significant aspect of this evidence is the opportunity for cross-examination, where both the defense and the prosecution can assess the credibility and validity of the witnesses’ statements. In scenarios such as assault cases, a detailed recounting by the victim can considerably affect the jury’s perspective.

Digital Evidence

In our rapidly digitizing world, digital evidence has ascended to prominence. It encompasses any information or data stored or conveyed in binary form that the court can rely upon. Texts, emails, or even social media posts can serve as evidence in modern legal scenarios. However, the nature of digital evidence often demands expert forensic scrutiny to confirm its genuineness and relevance.

As an example, in harassment cases, a series of menacing messages on an online platform can serve as evidence against the alleged offender.

In the intricate world of felony cases, interlinking the appropriate evidence with the essential elements of proof can make the difference between conviction and acquittal. The evidence serves as the backbone of any case, and its appropriate presentation and interpretation are essential to ensuring justice.

How to File Evidence in Criminal Court for a Felony

Disclaimer: Handling evidentiary matters is difficult. It’s best to have legal representation to handle these cases. With a lawyer, this task becomes manageable. Without a lawyer, you risk potential missteps.

Let’s dive deeper into each step of handling evidence.

Identification and Collection

Identification and collection is the initial and one of the most important phases in evidence handling. Here’s why:

Broad Scope: Before diving into specifics, it’s important to cast a wide net. Every piece of information or physical object could potentially be relevant. By working closely with an attorney, you ensure that no stone is left unturned. An attorney, with their experience, knows where to look and what might be relevant.
Expert Assistance: In some cases, especially those involving digital or forensic evidence, expert witnesses might be required to retrieve or identify certain pieces of evidence. This could range from cyber experts tracing digital footprints to forensic experts analyzing DNA samples.
Preventing Contamination: Right from the start, care needs to be taken to prevent the contamination of evidence. For instance, a crime scene must be cordoned off, and only authorized personnel should be allowed access.


Once evidence is identified and collected, preservation becomes important for the following reasons:

  • Maintaining Integrity: The court places significant importance on the authenticity of evidence. Any sign of tampering or degradation could lead to evidence being ruled inadmissible. For instance, biological samples, like blood or tissue, need to be stored under specific conditions to prevent decomposition.
  • Chain of Custody: Maintaining a clear and unbroken chain of custody ensures that the evidence has been in safe hands from the point of collection to its presentation in court. This chain provides a documented trail showing who had access to the evidence and when.


Documentation is the meticulous process of logging every detail related to the evidence, and it’s important for these reasons:

  • Reference and Retrieval: A well-documented log allows for quick reference and retrieval of evidence. This becomes especially important in cases with vast amounts of evidence or when a case stretches over a long period.
  • Detailing Specifics: Documentation isn’t just about naming the evidence. It involves logging specifics – where it was found, the date and time of collection, the condition it was in, any unique markers or identifiers, and the personnel involved in its collection and storage.
  • Reinforcing Authenticity: A comprehensive log further reinforces the authenticity and reliability of the evidence, ensuring it hasn’t been misplaced or mishandled.


Finally, submission is about formally presenting the evidence to the court. Here’s why each detail matters:

  • Legal Protocols: Every jurisdiction has its set of rules and protocols for submitting evidence. These might dictate the format, packaging, and even the labeling of evidence. Abiding by these ensures the evidence is accepted without issues.
  • Timelines: Courts often have strict timelines for when evidence can be submitted, especially in pre-trial phases. Missing these deadlines can lead to evidence being ruled inadmissible, no matter its relevance.
  • Attorney’s Role: An experienced attorney knows the intricacies of submission. They understand the nuances of legal protocols and the importance of timing, ensuring the evidence is presented in the best possible light.

Handling evidence is a meticulous process, and each stage plays a critical role in ensuring the evidence’s integrity, authenticity, and admissibility in court.

What If This Is Not Accepted by the Courts as Evidence?

If the court doesn’t accept certain evidence:

  • Understand the Reason: Reasons can range from evidence being irrelevant to being unlawfully obtained.
  • Refile or Appeal: With the guidance of an attorney, you can refile or appeal the court’s decision.
  • Alternative Evidence: An attorney might find another way to present the same facts using different evidence.
