In personal injury cases, evidence can determine if a claim is successful or a failure. Physical evidence, surveillance footage, accident reports, medical reports, and electronic data all can play a major role in proving liability and who might be responsible in an accident. However, some types of evidence can be lost, overwritten, or even destroyed if efforts aren't made to preserve it.
One legal tool that is often used to stop the destruction of evidence is a spoliation letter. What is a spoliation letter in personal injury? It's a legal letter that is sent to notify a person that specific types of evidence in a legal case must be preserved.
Understanding how spoliation letters work can help injured individuals recognize why attorneys often send them soon after an accident.

What Is Spoliation in Personal Injury Law?
The term "spoliation" refers to the destruction, alteration, or failure to preserve evidence relevant to a legal case.
Evidence might be considered to be destroyed if it's:
Intentionally erased
Accidentally deleted
Lost due to negligence
Overwritten by automated systems
For instance, surveillance video might get erased after a certain number of days. If a business doesn't save the footage after learning that it might be evidence in a personal injury case, that footage would likely be considered destroyed evidence.
Courts generally expect that an individual or business would preserve critical evidence once they know that it's crucial evidence. If they don't, however, there are serious legal consequences.
What Is a Spoliation Letter?
A spoliation letter, or sometimes called a preservation request or preservation letter, is a formal request sent to a person, company, or organization telling them they must preserve key evidence as its related to a personal injury claim.
The letter explains that the evidence in question could be related to a legal claim, and that the evidence cannot be destroyed, changed, or deleted.
A spoliation letters helps to ensure that vital evidence is available in a potential legal case.
When Spoliation Letters Are Used in Personal Injury Cases
Spoliation letters are common after car accidents because video footage can disappear quickly. Examples of this include:
Car Accidents
In a car accident, a spoliation letter often asks to preserve things like dash cam footage, vehicle data recorders (black box data), traffic camera recordings, and business surveillance footage.
This is very important in areas like Long Island where businesses or traffic cams might have caught footage of the parties involved in an accident. These are some reasons to consider a dashcam.
Truck Accidents
Commercial trucking companies often have evidence like electronic logging device (ELD) records, driver logs, vehicle maintenance logs, and GPS tracking data. A spoliation letter might request that these records remain preserved.
Slip and Fall Accidents
Businesses often use surveillance cameras inside stores and around parking lots. In a slip and fall, these cameras might have evidence, so it's common to ask businesses to keep any footage they have.
Workplace or Construction Accidents
When there is an accident at a workplace or on a construction site, other types of evidence may be needed including safety reports, inspection logs, incident reports, equipment maintenance logs, and site surveillance footage.
Missing evidence can greatly affect these cases, so oftentimes, a personal injury lawyer will send out preservation requests very quickly following an incident. For more information, this car accident law firm in Long Island may be able to help.
What Evidence Can a Spoliation Letter Protect?
The spoliation of evidence can greatly affect the outcome of a case. In these cases, companies and businesses are often asked to keep the following:
Surveillance camera recordings
Dashcam footage
Cell phone records
Emails and text messages
Computer data
Vehicle electronic data
Maintenance logs
Inspection reports
Medical records
Photos or videos related to the incident
The letter that is sent typically identifies the specific evidence that must be saved and explains why it may be relevant.
Who Receives a Preservation Request?
Preservation requests might be sent to anyone who controls evidence. This isn't necessarily the responsible party, but it could be.
Common people and entities that are asked to preserve important evidence include:
Businesses
Property owners
Trucking companies
Employers
Insurance companies
Government agencies
Drivers involved in accidents
In many cases, an attorney might send letters to more than one party to ensure that any potential evidence available is saved. They can also provide insight on how dash cam can help prove fault in rideshare accidents in NY.
What Happens After a Spoliation Letter Is Sent?
After getting a spoliation letter, the recipient is expected to take reasonable steps to preserve the relevant evidence. This might include:
Saving video footage
Backing up electronic records
Securing physical evidence
Preventing automatic deletion of data
If the evidence is properly preserved, it can be requested if a lawsuit is filed.
Consequences of Destroying Evidence
If a party destroys evidence after receiving a spoliation letter—or after they should reasonably know litigation may occur—courts may impose penalties.
Possible consequences can include:
Monetary sanctions
Restrictions on legal defenses
Jury instructions allowing negative assumptions
Dismissal of claims or defenses in severe cases
For example, a court may allow a jury to assume that destroyed evidence would have been unfavorable to the party responsible for its destruction.
Because of these potential penalties, organizations often take spoliation letters seriously.
Why Spoliation Letters Are Sent Quickly
Timing is often critical when it comes to preserving evidence.
Many types of data are automatically deleted after short periods. For example:
Security cameras may overwrite recordings after 24–72 hours
Dashcams may loop-record over older footage
Electronic records may be purged under data retention policies
Sending a spoliation letter quickly after an accident can help prevent valuable evidence from being permanently lost.
Spoliation Letters and the Legal Process
It is important to understand that sending a spoliation letter does not automatically start a lawsuit.
Instead, the letter serves as a precautionary step that helps protect evidence in case legal action becomes necessary.
If a lawsuit is eventually filed, the preserved evidence may be requested through the discovery process and used to support the claim.

Work with a Personal Injury Lawyer if You Need to Preserve Evidence
In personal injury cases, evidence can disappear quickly. Surveillance footage may be overwritten, electronic records may be deleted, and physical evidence may be discarded unless steps are taken to preserve it.
A spoliation letter is an important legal tool that notifies individuals and organizations that certain evidence must be preserved because it may be relevant to a potential claim. By requesting preservation early, injured individuals and their attorneys can help ensure that critical evidence remains available during the legal process.
When used properly, spoliation letters can play a significant role in protecting the integrity of evidence and helping courts determine what truly happened in an accident.
