Spoliation of Evidence: What Happens When Evidence “Disappears”

What Spoliation of Evidence Means

Spoliation of evidence happens when important evidence connected to a legal claim is destroyed, altered, lost, or not properly preserved.

In injury cases, evidence can be the difference between a strong claim and a disputed one. It may help prove fault, show how the accident happened, confirm a dangerous condition, or connect the injuries to the incident.

Sometimes evidence disappears by mistake. Other times, a person, company, property owner, or insurer fails to preserve records that could be unfavorable to them. Either way, missing evidence can make the case harder to prove and may affect how a court evaluates the claim.

Why Missing Evidence Can Change an Injury Case

A strong personal injury claim depends on documentation. Medical records matter, but so do photos, videos, electronic data, witness statements, maintenance records, and physical evidence from the scene.

When evidence disappears, insurance companies may argue that the injured person cannot prove what happened. They may claim the hazard did not exist, the driver was not at fault, the injuries are exaggerated, or the accident occurred differently than described.

That is why preserving evidence quickly can be so important. The longer a case waits, the easier it becomes for key proof to be erased, repaired, overwritten, or discarded.

Common Types of Evidence That Can Disappear

Modern injury cases often involve both physical evidence and electronic records. Some evidence may be lost within days if no one takes steps to preserve it.

Surveillance Footage

Video footage is one of the most common types of evidence lost after an accident. Businesses, parking lots, apartment complexes, homes, and public areas may all have cameras that captured part of the incident.

• Store security camera footage
• Parking lot surveillance video
• Doorbell camera footage
• Traffic camera footage
• Dash camera video

Many systems automatically overwrite footage after a short period. If a preservation request is not sent quickly, the video may be gone before the injured person even knows it existed.

Black Box and Vehicle Data

Commercial trucks and many passenger vehicles may contain electronic data that helps explain what happened before impact. This data can be especially important when speed, braking, or driver behavior is disputed.

• Vehicle speed
• Braking activity
• Steering inputs
• Acceleration
• Seatbelt use
• Crash timing information

In serious car accident cases, electronic vehicle data may help show whether a driver tried to stop, how fast the vehicle was moving, or whether the crash could have been avoided.

Physical Evidence and Damaged Property

Physical evidence can also disappear when damaged vehicles are repaired, products are thrown away, or dangerous conditions are fixed before they are photographed or inspected.

• Damaged vehicles
• Broken stairs or railings
• Defective products
• Torn clothing
• Skid marks
• Debris patterns
• Damaged machinery or equipment

Once the scene changes, it may be much harder to prove what condition existed at the time of the accident.

Maintenance and Company Records

Businesses, trucking companies, property owners, and employers may hold records that help prove negligence. These records can show whether there were prior complaints, missed inspections, unsafe repairs, or ignored safety issues.

• Inspection reports
• Maintenance logs
• Driver logs
• Incident reports
• Safety complaints
• Internal emails or messages

Some records are routinely deleted or overwritten under normal company practices unless someone sends a formal request to preserve them.

What a Preservation Letter Does

A preservation letter, sometimes called a spoliation letter, is a written notice telling a person or company to preserve evidence because a legal claim may be coming.

The letter may ask the recipient to preserve video footage, electronic data, inspection records, maintenance files, vehicles, equipment, photographs, emails, and other information connected to the incident.

Once a party knows that evidence may be relevant to a legal claim, destroying or failing to preserve it can create serious consequences. A preservation letter helps establish that the party was placed on notice.

What Happens If Evidence Is Destroyed?

The consequences depend on what evidence was lost, how important it was, and whether it was destroyed accidentally, negligently, or intentionally.

Courts May Impose Sanctions

If a court finds that evidence was improperly destroyed, the court may impose penalties. These can vary depending on the seriousness of the conduct and how much the missing evidence affected the case.

• Monetary sanctions
• Restrictions on certain defenses
• Exclusion of testimony
• Jury instructions about missing evidence
• Adverse inferences against the party who lost the evidence

An adverse inference means the jury may be allowed to assume the missing evidence would have been unfavorable to the party responsible for losing or destroying it.

Intentional Destruction Can Damage Credibility

When evidence is intentionally destroyed after a party knows a claim may exist, it can seriously damage that party’s credibility. Courts generally take deliberate evidence destruction seriously.

Examples may include a trucking company deleting driver records, a store erasing surveillance footage after an incident, a property owner repairing a dangerous condition before documentation, or a driver destroying phone data after a crash.

Evidence Can Disappear Faster Than People Realize

Many injured people assume evidence will still be available weeks or months later. In reality, key proof may disappear quickly.

Automatic Deletion Systems

Surveillance systems often overwrite video automatically. Depending on the system, footage may be erased after 24 hours, 7 days, 30 days, or another short period.

Without a quick preservation request, valuable footage may be permanently lost before anyone has a chance to review it.

Accident Scenes Change Quickly

Physical conditions may also change fast. Vehicles are repaired, damaged items are discarded, spills are cleaned, ice melts, skid marks fade, and broken property may be fixed.

That does not always mean the case is lost, but it does make documentation harder.

What Injured Victims Can Do to Help Preserve Evidence

Taking early action after an accident can help protect important proof before it disappears.

Photograph Everything Possible

Photos and videos can help preserve conditions as they existed at the time of the accident. If possible, document vehicle damage, road conditions, hazards, injuries, weather, debris, lighting, and surrounding areas.

Request Incident Reports

If the injury happened at a business, rental property, workplace, or public location, ask whether an incident report will be created. Keep copies of anything provided to you.

Avoid Repairing or Discarding Key Evidence

Damaged vehicles, defective products, broken equipment, shoes, clothing, helmets, or other items may later become important evidence. Do not throw them away before their importance is understood.

Get Legal Help Early

Early legal involvement can help identify what evidence exists, who controls it, and what must be preserved. Preservation letters can be sent before video, records, or electronic data are lost.

Missing Evidence Does Not Always End the Case

A claim may still move forward even if some evidence is missing. Other proof may still support the case, including witness testimony, medical records, photographs, expert analysis, and remaining physical evidence.

However, proving liability often becomes harder when key evidence disappears. Acting quickly gives injured victims the best chance to preserve the facts before the record changes.
