As an experienced and trusted litigation and dispute resolution attorney, Ekaterina (Katya) Long has built a signature practice in fiduciary litigation and trust and estate disputes. She represents fiduciaries, beneficiaries, and heirs in contested trust and estate matters, breach of fiduciary duty claims, and related disputes over the administration and control of family assets and closely held businesses. Katya is also certified by the State Bar of Texas as eligible to represent guardianship applicants and accept court appointments in guardianship proceedings, including appointments as attorney ad litem.

Alongside this core focus, Katya maintains a robust commercial litigation practice, handling banking and finance litigation, partnership and ownership disputes, and trade secret litigation. She has handled claims for breach of contract, fraud, theft of trade secrets, tortious interference, and defamation.

Katya is skilled at efficiently preparing a case for trial—taking and defending depositions, conducting offensive and defensive written discovery, and arguing dispositive motions. She has secured pretrial dismissals and successfully handled administrative appeals. Most recently, Katya second-chaired and won a bench trial in an adverse-possession case.
