Clients hire attorneys to protect their legal rights. When the attorney’s own errors are what destroy those rights, Washington law recognizes that the client may have an entirely new claim… this time, against the lawyer.
When you retain a law firm in Seattle, you place significant trust in your counsel’s professional diligence. Whether you are pursuing commercial litigation or recovering from a serious injury, a missed filing deadline or procedural failure can permanently eliminate your right to recovery — not because your case was weak, but because of an attorney error that should not have occurred. Washington law provides a civil pathway to hold negligent attorneys accountable through a legal malpractice claim.
Fatal errors: missed timelines and procedural failures
Every civil cause of action in Washington is governed by a statutory deadline under the Revised Code of Washington. Standard personal injury claims and oral contract disputes must be filed within three years. A missed deadline requires the court to grant a motion to dismiss, and the right to pursue the claim is permanently lost.
Other procedural failures can produce the same result:
- Summary judgment default: Missing the mandatory window to file a responsive brief under Washington Superior Court Civil Rule 56 allows a court to rule entirely in the opposing party’s favor without the merits of the case ever being heard.
- Appellate deadline: Failing to file a Notice of Appeal within the 30-day window permanently extinguishes the right to challenge a trial court’s ruling.
These failures share a common feature: they cannot be undone through a later motion or correction, which is what makes attorney errors of this type so consequential.
Proving legal malpractice in Washington
A Washington legal malpractice claim requires establishing four elements: the existence of an attorney-client relationship, a breach of the professional standard of care, a direct causal link between the breach and the client’s harm, and quantifiable damages.
The most demanding aspect of this framework is what courts call the “case within a case” doctrine. To prevail, the client must essentially relitigate the underlying matter and demonstrate that they would have won, and recovered a specific amount, but for the attorney’s error. This requires building two parallel factual records simultaneously.
One important protection for affected clients is the Continuous Representation Rule. Under Washington law, the three-year statute of limitations for legal malpractice does not begin to run while the attorney continues to represent the client on the same matter. This tolling rule gives clients additional time to recognize that an error occurred and take action.
Other actionable breaches beyond missed deadlines include failing to depose key witnesses within the case schedule and entering unauthorized settlements without the client’s informed consent.
If you believe a prior attorney’s errors compromised your case, speaking with an experienced Washington legal malpractice attorney as early as possible gives you the best opportunity to evaluate what was lost and whether a viable malpractice claim exists.
