Don’t Lose Your Evidence: Understanding Spoliation in Personal Injury Cases

TL;DR
Spoliation = destroying, altering, or losing evidence you have a duty to preserve
When duty begins: As soon as you reasonably anticipate a lawsuit or legal claim
Consequences: Courts can impose sanctions, assume destroyed evidence was harmful to your case, or even dismiss claims
Digital evidence: Dash cam footage, phone photos, and electronic data need special preservation protocols
Critical first steps: Stop all auto-delete functions, make copies, document everything

What Is Spoliation of Evidence?

Spoliation occurs when someone destroys, alters, or fails to preserve evidence that they have a legal duty to maintain. In personal injury cases, this can happen accidentally or intentionally, but the consequences are the same—it can seriously damage your case.

The Legal Definition

Courts generally define spoliation as the destruction or significant alteration of evidence, or the failure to preserve property for another’s use as evidence in pending or reasonably foreseeable litigation.

Key elements:

Duty to preserve evidence existed
Breach of that duty occurred (evidence was destroyed, altered, or lost)
Resulting prejudice to the opposing party

When the Duty to Preserve Begins

The duty to preserve evidence typically begins when:

An accident occurs and injuries result
You reasonably anticipate filing a legal claim
You receive notice of a potential lawsuit
Litigation is formally commenced

Critical point: The duty often begins immediately after an accident, not when you formally file a lawsuit.

Common Types of Evidence Spoliation

Digital Evidence Spoliation

Dash cam footage:

Automatic overwrite loops delete crucial clips
Memory cards get reformatted or corrupted
Footage edited or trimmed improperly

Smartphone evidence:

Photos automatically deleted by cloud storage limits
Text messages cleared from memory
Location data disabled or erased

Vehicle computer data:

Event data recorders (EDR) overwritten
Diagnostic codes cleared during repairs
Infotainment system data lost during service

Physical Evidence Destruction

Vehicle damage:

Cars repaired or totaled before proper documentation
Parts replaced without preserving originals
Paint transfer or impact evidence lost

Scene evidence:

Skid marks fade or get cleaned
Road damage repaired quickly
Surveillance systems overwrite footage

Medical evidence:

X-rays discarded after treatment
Medical devices replaced or disposed
Treatment records lost or destroyed

Document Spoliation

Insurance correspondence deleted
Medical records destroyed per retention policies
Employment records purged
Financial documents discarded

Legal Consequences of Spoliation

Adverse Inference Instruction

Courts may instruct juries to assume the destroyed evidence would have been unfavorable to the party who destroyed it. This is often the most damaging consequence.

Example: If you delete dash cam footage, the jury might be told to assume the footage showed you were at fault.

Evidentiary Sanctions

Exclusion of evidence: Related evidence may be deemed inadmissible
Limited testimony: Witnesses may be restricted in what they can say
Burden shifting: The spoliating party may have to prove their innocence rather than the other side proving fault

Monetary Sanctions

Courts can order the spoliating party to:

Pay the opposing party’s attorney fees
Cover costs of attempting to recover lost evidence
Pay additional damages for prejudice caused

Case Dismissal

In extreme cases involving intentional spoliation or bad faith destruction, courts may:

Dismiss the spoliating party’s claims
Enter default judgment against them
Strike pleadings or defenses

Digital Evidence: Special Preservation Challenges

Automatic Deletion Systems

Many digital systems automatically delete data:

Dash cams: Loop recording overwrites old footage
Cloud storage: Auto-deletes to manage storage limits
Security systems: Overwrite after set periods
Phone apps: Clear data automatically

Solution: Immediately disable auto-delete functions after an accident.

Data Integrity Issues

Digital evidence faces unique challenges:

Metadata preservation: Time stamps and location data can be altered
Chain of custody: Multiple copies need tracking
File corruption: Data can become damaged or unreadable
Format obsolescence: Technology changes can make files inaccessible

Best Practices for Digital Preservation

Immediate action: Stop all automatic deletion/overwrite functions
Multiple copies: Create copies on different storage media
Hash verification: Use checksums to verify file integrity
Metadata preservation: Keep original file creation data intact
Professional help: Consider forensic data recovery specialists

Step-by-Step Evidence Preservation Protocol

Immediate Actions (First 24 Hours)

Digital evidence:

Lock/protect all recordings using device controls
Remove power from dash cams to prevent overwriting
Save phone photos/videos to multiple locations
Screenshot text messages and social media posts
Disable auto-delete on all devices and apps

Physical evidence:

Photograph everything from multiple angles
Document vehicle damage before moving cars
Collect debris and physical evidence at scene
Note weather conditions and lighting
Identify witnesses and get contact information

First Week Actions

Create backup systems:

Copy digital files to multiple storage devices
Upload to secure cloud storage with retention controls
Create checksums (digital fingerprints) of all files
Document chain of custody for all evidence
Organize files with clear naming conventions

Preserve physical evidence:

Store damaged items in secure, dry location
Photograph healing injuries regularly
Keep all medical records and bills
Save receipts for all accident-related expenses
Document ongoing symptoms in writing

Ongoing Preservation

Regular maintenance:

Check backup integrity monthly
Update storage systems before they become obsolete
Maintain access to all digital files
Document any changes or access to evidence
Communicate with attorneys about evidence status

Common Preservation Mistakes to Avoid

Accidental Destruction

Auto-overwrite systems: Forgetting to disable dash cam loop recording Cloud storage limits: Letting automatic deletion remove crucial photos Device updates: Software updates that clear app data Repair decisions: Fixing vehicles before documenting damage

Inadequate Documentation

Poor chain of custody: Not tracking who accessed evidence when Missing metadata: Losing creation dates and location information Incomplete copies: Partial backups that miss crucial data No verification: Failing to confirm copies are complete and accurate

Premature Disposal

Settlement assumptions: Throwing away evidence after initial settlement discussions Insurance pressure: Disposing of damaged property at insurer’s request Storage costs: Getting rid of evidence to save storage expenses Time passage: Assuming old evidence is no longer relevant

Industry-Specific Considerations

Commercial Vehicles

Fleet management systems often overwrite data quickly
Electronic logging devices (ELD) have limited retention periods
GPS tracking data may be purged automatically
Maintenance records crucial for mechanical failure claims

Rideshare and Delivery

Driver apps track location and timing data
Customer communications may contain relevant information
Platform policies for data retention vary widely
Independent contractor status affects evidence duties

Motorcycle and Bicycle Accidents

Helmet cameras have limited storage capacity
Fitness apps may track speed and route data
Social media posts about rides can be relevant
Equipment failure evidence needs immediate preservation

After Minor Incidents

Even minor accidents can escalate, so:

Preserve everything initially—you can’t recreate lost evidence
Document thoroughly—details forgotten quickly
Get legal advice before disposing of anything
Maintain storage systems until claims are fully resolved

State-Specific Considerations

Oregon and Washington

Both states recognize spoliation claims and remedies:

Oregon: Courts have broad discretion in imposing sanctions
Washington: Strong precedent for adverse inference instructions
Federal court: May apply different standards in diversity cases

Statutory Requirements

Some types of evidence have specific legal requirements:

Medical records: HIPAA compliance affects preservation
Employment records: State laws govern retention periods
Business records: Regulatory requirements may mandate preservation

Red Flags: When Spoliation Might Be Occurring

Watch for these warning signs from other parties:

Insurance companies:

Pressure to settle quickly before evidence review
Requests to dispose of damaged property immediately
Claims that evidence is “not relevant” to the case

Opposing parties:

Delays in producing requested evidence
Claims that evidence was “accidentally” destroyed
Inconsistent stories about evidence availability

Businesses:

Standard policies of quick evidence destruction
Resistance to preserving video surveillance
Claims that data retention is “too expensive”

Recovery Options When Evidence Is Lost

Digital Recovery Techniques

Even “deleted” digital evidence may be recoverable:

File system recovery: Undelete tools for recent deletions
Forensic imaging: Deep recovery from storage devices
Cloud backups: Automatic backups may preserve data
Service provider data: Third parties may retain copies

Alternative Evidence Sources

When primary evidence is lost, consider:

Third-party recordings: Other vehicles’ dash cams, security cameras
Public records: Traffic camera footage, 911 call records
Expert reconstruction: Using physical evidence to recreate events
Witness testimony: People who saw or documented the incident

The Bottom Line on Evidence Preservation

Start immediately: Evidence preservation begins the moment an accident happens Document everything: More is better when it comes to evidence Get help: Serious cases require professional assistance Stay vigilant: Evidence can be lost accidentally even with good intentions Think long-term: Legal cases can take years to resolve

Remember: You can’t “un-lose” evidence. Once it’s gone, it’s typically gone forever. The time and effort spent preserving evidence immediately after an accident is always worthwhile—even if you ultimately don’t need to use it in litigation.

Evidence preservation isn’t just about following rules; it’s about protecting your ability to tell your story accurately and completely when it matters most.
