FAQs
-
Unlike in employment lawsuits, where businesses are nearly always defendants, businesses are just as likely to sue as be sued in commercial litigation. If you think your contractual or other rights have been breached, we will evaluate and propose a range of realistic options, including litigation alternatives. If you have received a demand letter or lawsuit, we will prepare a no-nonsense exposure analysis and vigorously pursue your chosen strategy.

Litigation takes on a life of its own and should not be entered into lightly. When another business owes or has cost your business money, we will take a comprehensive look at your likely chances of recovery compared to the fees you will likely incur. We will assess whether relevant contracts provide prevailing party attorney’s fees that could make a smaller claim worthwhile, whether the defendant’s financial condition could make an otherwise valuable case worthless, and whether there is insurance coverage that could affect matters. Ultimately, it will be your decision how much risk to tolerate and how much weight principle, reputation, and deterrence should carry compared pure economics. Our job is to make sure that decision is informed by the best possible legal analysis. Click here to schedule a consultation.

For commercial litigation defense, we offer traditional hourly billing at our standard rates, typically with an initial advance deposit and periodic replenishment. Many of our clients instead choose our modular flat-fee structure because it brings a sense of structure and foresight to litigation costs — assigning fixed fees to major phases and events in a way that supports both budgeting and strategic planning.
We offer our commercial litigation plaintiff clients traditional hourly billing, but on a case-by-case basis we may agree to fee models where we share in some of the risk — and the upside — of your case. Such models include a pure contingency, a blended contingency fee with reduced hourly rate, or a reduced hourly rate with a flat “success fee” if a pre-defined goal is achieved.
Fee arrangements will be offered to particular clients at our sole discretion. Click here to schedule a consultation and learn more.

A breach of contract occurs when one party fails to fulfill their legal obligations under a valid agreement. This can include failure to perform on time, not performing at all, or performing incompletely. California law allows businesses to pursue remedies such as monetary damages, specific performance, or contract cancellation.

Tortious interference involves a third party unlawfully disrupting a business relationship or contract, either existing or expected. This can include intentional acts that cause one party to breach a contract or hinder a potential agreement, resulting in financial harm.
-
A breach of fiduciary duty happens when a person in a position of trust—such as a business partner, corporate officer, or board member—acts in their own interest rather than those they are required to serve. This can lead to claims for damages, removal from position, or restitution.
