📝 How Evidence Preservation Letters Protect Your Case
See how these formal notices prevent companies from destroying critical documents and strengthen your legal position.
When someone develops mesothelioma or another asbestos-related illness, the success of their legal claim depends heavily on the strength of the evidence available. But because asbestos exposure often occurred decades earlier, crucial records—like product manuals, safety reports, purchase logs, and employment files—may be lost, archived, or deliberately discarded unless action is taken immediately.
That is why attorneys use Evidence Preservation Letters, also known as spoliation letters, to protect the integrity of your case. These formal notices legally warn companies, employers, and product manufacturers that they must preserve all documents, materials, and electronic records that may be relevant to your asbestos exposure.
If sent early, these letters can prevent corporations from destroying or altering key evidence. If ignored, courts may impose strict penalties that ultimately strengthen your case.
If you think you were exposed to asbestos or recently received a mesothelioma diagnosis, call 800.291.0963 to get help sending the necessary preservation notices immediately.
📘 What Is an Evidence Preservation Letter?
An evidence preservation letter is a legally binding notice sent by your attorney to any party that may possess documents related to your asbestos exposure. These letters:
-
Inform companies that you intend to file a claim
-
Require them to preserve all potential evidence
-
Warn that destruction of records may result in sanctions
-
Apply to both paper and electronic documents
-
Cover physical materials, products, and job-site files
Under U.S. law, once a company receives a preservation letter, it must immediately suspend any document-destruction practices (including routine shredding or digital deletion) involving relevant materials.
The earlier these letters are sent, the more evidence remains intact.
🗂️ Why Evidence Preservation Matters in Asbestos Litigation
Asbestos lawsuits rely on records that show:
-
Which asbestos-containing products were used
-
Who manufactured them
-
Where and when they were installed
-
How often workers were exposed
-
What the company knew about asbestos dangers
-
Whether safety warnings were ignored
-
Whether adequate protections were provided
Because exposure often occurred 20–60 years earlier, companies may no longer keep documents unless legally required to do so. Without preservation letters, critical evidence may disappear forever.
Key evidence that may be saved:
-
Purchase orders and invoices
-
Material Safety Data Sheets (MSDS)
-
Shipping and warehouse records
-
Old plant blueprints
-
Internal memos about asbestos risk
-
Employee logs and job-assignment lists
-
Maintenance and repair documents
-
Product testing and safety reports
-
Emails or digital files referencing asbestos
These records can significantly strengthen your case and link your illness to specific manufacturers and job sites.
🏛️ How Preservation Letters Strengthen Your Legal Case
Sending evidence preservation letters provides several major advantages that can shape the outcome of your case.
1. They Block Companies From Destroying Records
Once notified, defendants must stop:
-
Shredding documents
-
Deleting files or emails
-
Discarding equipment
-
Erasing databases
-
Clearing out old product records
Any deletion after receiving the letter is considered spoliation of evidence and is punishable by the court.
2. They Place Legal Responsibility on the Company
If a company violates the letter, judges may:
-
Assume missing evidence favored the victim
-
Sanction the defendant financially
-
Limit their defense arguments
-
Issue default judgments in extreme cases
This creates strong incentive for companies to comply.
3. They Preserve Hard-to-Find Historical Records
Because asbestos use peaked in the 1940s–1980s, many records exist only in:
-
Old warehouses
-
Basement file rooms
-
Retired employee storage
-
Microfilm archives
-
Outdated data systems
Preservation letters force companies to search these locations and maintain anything relevant.
4. They Help Identify Additional Defendants
As documents are turned over, attorneys often discover:
-
Additional product manufacturers
-
Contractors
-
Suppliers
-
Equipment makers
-
Insulation companies
-
Former employers
This can increase your total compensation by expanding the number of responsible parties.
5. They Improve Your Settlement Position
When a company realizes that damaging evidence may surface, they are more likely to:
-
Settle sooner
-
Offer a higher amount
-
Avoid trial risks
Evidence preservation directly influences negotiation strength.
📨 When Should Preservation Letters Be Sent?
Attorneys typically send these letters immediately after:
-
Your diagnosis of mesothelioma
-
A suspicion you were exposed at a job site
-
Discovery of an asbestos-containing product
-
Early investigation into your work history
-
A consultation where exposure is likely
Every day that passes increases the risk of document loss.
Fast action = stronger evidence = stronger compensation.

📑 What Information Is Included in a Preservation Letter?
While each notice is customized to the case, most include:
-
Your name (or the victim’s name)
-
Date of diagnosis
-
Suspected exposure locations
-
Types of evidence to preserve
-
Legal obligation to halt document destruction

Notification that litigation is anticipated

⚖️ What Happens If a Company Ignores the Letter?
Courts take evidence destruction very seriously. If a defendant ignores a preservation letter, the judge may impose:
-
Monetary sanctions
-
Instructions to the jury to assume the missing evidence was harmful to the defendant
-
Exclusion of certain defense arguments
-
Default judgment against the defendant
-
Mandatory adverse inference rulings
In some cases, the penalties alone have been enough to encourage early settlement.
🔍 How Evidence Preservation Supports Expert Testimony
Mesothelioma cases rely heavily on expert witnesses such as:
-
Industrial hygienists
-
Occupational safety experts
-
Medical specialists
-
Product investigators
-
Corporate historians
Preserved documents allow these experts to:
-
Trace asbestos fiber migration
-
Identify product use at specific job sites
-
Document company knowledge of dangers
-
Reconstruct exposure levels
-
Prove negligence and failure to warn
Experts are far more effective when evidence is preserved.

-
Prevent destruction of documents
-
Protect your right to compensation
-
Strengthen expert testimony
-
Improve settlement leverage

Preserve rare historical records

Hold companies legally accountable
