Pantea (pronounced Pawn-tee) Yashar 

Pantea advises on, litigates, and resolves a wide range of real estate and business disputes, with a focus on real property and projects in Southern California for large-scale commercial and residential landlords and developers. From protecting their rights to negotiating resolutions to contentious challenges involving developers, property owners, commercial lease holders, and buyers and sellers in the nation’s most expensive property markets, Pantea adds tremendous value with her strategic handling of complex matters.

Pantea manages the full spectrum of her clients’ legal needs and obligations. Pantea’s creatively assertive resolution style centers around positioning clients purposefully from the outset and powerful client advocacy. Appreciated for her market savvy and big-picture vision, Pantea has experience with all property types—shopping centers, mixed-use, retail, residential, industrial, and office buildings. Her litigation background also includes purchaser/seller and neighbor disputes, partition, easement, property line, quiet title, construction defect/breach, nuisance, and disability access issues.

Early in her career, Pantea served as Special Deputy Prosecutor for the City Attorney’s Office of Hermosa Beach, where she first chaired misdemeanor cases through verdict, and lectured on trial advocacy. Prior to joining ECJ, Pantea was a litigation attorney at the international law firm of Kirkland & Ellis LLP.

As an alumna of Harvard Law School, Pantea currently serves as the Vice President—At Large on the Executive Board of the Harvard Law School Association; this is a position she assumed following her two-year Presidency of the Association’s Los Angeles chapter. Southern California Super Lawyers has repeatedly recognized Pantea, initially as a Rising Star, and every year since 2017, as a Super Lawyer for excellence in real estate and business litigation. Pantea was named as a “Woman of Influence” by the Los Angeles Business Journal in 2022 and 2023, and as a Minority Leader of Influence in 2023.
