Darlene Pasieczny (“Pah-shetch-nee”) is a securities and fiduciary litigator, and appellate attorney. In addition, she leads the Investor Defenders practice group at Samuels Yoelin Kantor LLP.

Pasieczny’s knowledge in the field of securities litigation and FINRA arbitration gives her the edge to help her clients recover investment losses. Darlene is licensed in Oregon and Washington. However, her FINRA arbitration practice enables her to represent investors nationwide. This involves claims of financial advisor misconduct or defective securities products. FINRA arbitration is the main forum for resolution of legal disputes between investors and securities industry professionals. It is a specialized forum with its own procedural rules – and Darlene knows how to navigate them. Darlene regularly works with state and federal securities regulators to improve the rules of this forum.  Darlene also serves as a FINRA arbitrator. Visit the Investor Defenders site to learn more.

Darlene also represents parties in other financial and fiduciary litigation. These include representing trustees, beneficiaries, and other interested parties in trust and estate disputes such as will contests, undue influence claims, and nonjudicial amendments to trust terms.   Other types of cases include  shareholder rights cases, complex civil litigation, and elder financial abuse. Matters such are these may involve friends, family, or trusted caretakers in very difficult situations. Where possible, Darlene helps her clients resolve disputes by mediation or informal settlement.

Appeals happen.

Cases don’t always end at the trial level or arbitration award – sometimes a party appeals a decision. Darlene also represents parties in the appellate courts. She has successfully represented clients before the Oregon Court of Appeals, Oregon Supreme Court, the Washington State Court of Appeals, and on briefing to the Supreme Court of the United States. 

Recognized by her peers for her dedication to her practice.
