Smaller communities in Clackamas County include Boring, Brightwood, Colton, Eagle Creek, Government Camp, Marylhurst, Portland, Rhododendron, Welches. Residents of these areas follow the same Oregon rules, use the same Clackamas County Circuit Court, and can request a free claim review from anywhere in the county.

Oregon generally gives an injured person two years from the date of injury to file a personal injury lawsuit (ORS 12.110(1)); medical malpractice is different (two years). Wrongful death claims follow their own deadline, which can differ from the one above. Claims against a city, county, school district or state agency follow separate and often much shorter deadlines. Once the deadline passes, the Clackamas County Circuit Court will dismiss the case regardless of how clear the fault was, so the practical rule in Clackamas County is to get legal advice early.

Oregon follows modified comparative negligence (51% bar). In plain terms, you can recover as long as you were not more than 50% at fault, and your award is reduced by your share of fault. Insurance adjusters apply this rule from the first phone call, which is why the way an accident is described and documented in the days after it happens in Clackamas County has a direct effect on what a claim is worth.

After a crash in Clackamas County, the at-fault driver's liability insurance is the primary source of compensation. Oregon requires drivers to carry only 25/50/20 in coverage (thousands of dollars for bodily injury per person, per accident, and property damage), which serious injuries quickly exhaust. Underinsured motorist coverage on your own policy and claims against additional responsible parties often make the difference in Clackamas County cases.

Lawsuits arising from accidents in Clackamas County are typically filed in the Clackamas County Circuit Court, the trial court of general jurisdiction for Clackamas County, although cases can sometimes be filed where the defendant resides or does business, and claims against out-of-state trucking companies or manufacturers may end up in federal court. Most claims settle before trial, but the credible ability to try a case in Clackamas County is what moves insurers to pay fair value.

Employees injured on the job in Clackamas County are generally covered by Oregon workers' compensation, administered through the Oregon Workers' Compensation Division. Report the injury to your employer within 90 days — a late report can delay or put the claim at risk, and the exceptions vary by state — then file the formal claim within 90 days, because the notice of accident is the claim (ORS 656.265); a late claim survives only in limited cases and never after one year. Workers' compensation does not pay for pain and suffering, so when a third party such as a subcontractor, driver or equipment manufacturer caused the injury, a separate personal injury claim is often worth pursuing alongside it.
