How To Prepare A Successful Asbestos Exposure Lawsuit
A mesothelioma or asbestos-related disease diagnosis often comes decades after the asbestos exposure, which means building a strong legal claim requires reconstructing a past that may feel distant or incomplete. Understanding your filing deadline, documenting your exposure history, gathering medical records, and working with the right experts are the steps that determine how strong your asbestos exposure case becomes.
If you’re unsure where to start, Oslund Udo Little has represented asbestos clients in Washington and Oregon since 1995. Call our attorneys at 206-957-9510 to speak to our Washington team, or 503-447-6230 to speak with our Oregon team, on contact us online to schedule a free consultation.

- Proving your sources of exposure is key to strengthening your asbestos claim
- A work history showing you were at work sites with known asbestos can help you prove you were harmed
- Medical records can show the extent of the damage done by asbestos exposure
Know Your Deadline to File a Claim
The most important thing you can do to protect your case is to understand the deadlines that apply to your case. You have to file a claim within the applicable statute of limitations. If you don’t, your claim will be time-barred.
Oregon’s statute of limitations is two years for personal injury claims and three years for wrongful death lawsuits, while both personal injury and wrongful death claims in Washington have a three-year statute of limitations.
In both Washington and Oregon, the discovery rule often applies to asbestos cases. This means the limitations period would start when you knew or reasonably should have known of the asbestos-related disease. This means you don’t have to worry that your statute of limitations started tolling on the day of exposure or the date of injury.
We know the timelines well and will help you file your claim on time. We will also start building a strong case early to gather the evidence you need to make your case before time runs out.
Proving Your Sources of Exposure
Because mesothelioma typically develops 20 to 50 years after initial asbestos exposure, one of the first and most important steps in building your case is establishing when, where, and how you were exposed to asbestos. The stronger this foundation, the clearer the link between your illness and the liable parties.
Useful evidence includes employment records, union records, military service records, product invoices, coworker testimony, and company documents showing that asbestos-containing materials were used at your specific worksites.
Don't Know Where You Were Exposed? OUL Can Help.
It’s common not to remember every detail of work done decades ago, and you don’t need to have all the answers before you call. At Oslund Udo Little, our attorneys are experienced at reconstructing exposure histories by tracing employment records, locating former coworkers, and identifying which asbestos-containing products were used at specific Pacific Northwest job sites, shipyards, and industrial facilities.
If exposure happened in Washington or Oregon, our attorneys likely already have records that can help prove it.
Proving Your Illness Through Medical Records
Gathering medical records is a key part of preparing your mesothelioma case. These records prove your diagnosis and document the severity of your illness. Some of the most important records include:
- Pathology reports: Confirm your diagnosis and cell type
- CT scans, X-rays, and PET scans: Document the location, extent, and stage of the cancer
- Biopsy results: Provide a definitive mesothelioma diagnosis
- Pulmonary function tests: Demonstrate how asbestos-related disease impacted your lung function
Our firm has established relationships with hospitals and treating physicians throughout Washington and Oregon. We will help you obtain your records and connect you with medical experts who can testify to your diagnosis, prognosis, and any ongoing care you may need. That testimony directly affects what you can recover for medical expenses, so getting it right matters.
Proving Your Work History
Filing a mesothelioma lawsuit requires identifying which employers or companies may be liable, and that starts with a detailed account of your work history. The most useful evidence typically includes:
- Employment history: Exact dates of employment, job titles, and day-to-day duties establish when your exposure occurred and who was responsible.
- Worksites: Shipyards, factories, refineries, power plants, military bases, and construction sites can be matched against historical records showing where asbestos-containing products were used.
- Specific job tasks: Details about what you actually did, such as removing insulation, cutting tile, replacing gaskets, or working around pipe insulation, can directly tie your work to asbestos exposure.
- Coworkers and witnesses: Former coworkers or supervisors can confirm your job duties, the conditions at your worksite, and the presence of asbestos.
- Safety practices: Whether your employer provided respirators, protective clothing, ventilation, or any asbestos safety training establishes whether you were adequately protected from known hazards.
Our investigators have helped workers at worksites throughout Washington and Oregon track down missing employment records and locate witnesses from decades past. We know how exposure occurred at many of these facilities and can help connect your history to the evidence needed to build your claim.
Gathering Witness Testimony
Asbestos cases are technically complex. You have to prove not just when and where exposure occurred, but also the full extent of the harm it caused. Expert witnesses play a central role in doing both.
Oslund Udo Little has established relationships with leading physicians who understand the science behind asbestos-related illness and know how to present that information clearly to a jury. They won’t just confirm that your exposure caused your illness. They’ll explain how, in terms that make sense to people who aren’t medical professionals.
Expert testimony can also address your economic losses and the long-term impact of your diagnosis on your quality of life. That testimony shapes what you can realistically recover, which is why the quality of your experts matters as much as the quantity of your evidence.
