Business Litigation

Southern California Business Dispute Lawyers

“We Could Do It Better”

Since 2001, the partners of Gates, Gonter, Guy, Proudfoot & Muench LLP have provided litigation and trial assistance to business owners in southern California. Prior to 2001, we worked at a large firm with a large number of attorneys who had a broad range of trial experience. We met and thought we could “do it better” by forming a company of highly experienced litigation lawyers.

The four partners of Gates, Gonter, Guy, Proudfoot & Muench LLP have 25 to 35 years of litigation experience for a combined total of:

  • 120 years of trial experience
  • Hundreds of trials handled
  • Approximately 400 trials handled to verdict

We handle virtually all civil, commercial, and business law disputes, including disputes involving:

  • Breaches of contract
  • Entertainment law, including disputes involving artists and professional athletes
  • The Uniform Commercial Code (UCC)
  • Regulatory issues
  • Commercial collections
  • Creditor bankruptcy
  • Antitrust proceedings
  • Fraud, conversion and the misappropriation of funds
  • Trade secrets and unfair competition
  • Copyrights and trademarks
  • Americans with Disabilities Act issues
  • Partnership, shareholder, officer and director issues
  • Joint venture
  • The sale or purchase of businesses
  • The dissolution of corporations and partnerships
  • Business interruption issues
  • Insurance coverage
  • Director and officer liability
  • Business and Professions Code Section 17200
  • Defamation and slander
  • Professional liability actions
  • Advertising injuries

We are skilled at handling all of the intricacies of business litigation, from the initial steps of your case to negotiations, arbitration, mediation, or courtroom litigation. For instance, we can act as Cumis counsel for insured individuals in homeowner and auto insurance disputes, and we can represent any party in homeowners association disputes.
