Financial elder abuse is one of the fastest growing areas of the law, affecting one of the most vulnerable sectors of our society. California’s elder abuse statutes provide extra protections to those 65 years of age and older who were victimized by the fraud or theft, most often a “loved one” who takes advantage of mom, dad, aunt, uncle, grandma or grandpa’s incapacity.


We represent beneficiaries, heirs, administrators, executors, trustees and conservators/conservatees in cases involving disputing a will or trust, claims of breach of fiduciary duty, fiduciary misconduct and fraud, misfeasance and malfeasance in estate administration, investment mismanagement, financial elder abuse, incapacity, and undue influence.


We represent businesses and business owners in breach of contract disputes, shareholder derivative lawsuits, trade secret and intellectual property litigation, non-competes, labor and employment litigation, breach of employment contract litigation, fraud litigation, breach of fiduciary duty litigation, negligence claims, and internal and external investigations.
