Pasadena Business Litigation Attorney for Contract and Partnership Disputes
A disagreement with a business partner, a client who won’t pay, or a vendor who broke a deal can threaten the company you spent years building. The longer a conflict sits unresolved, the more it costs you in time, money, and opportunity.
Robert G. Petrovich, a Pasadena business litigation lawyer licensed in California since 1978, holds a business degree from the University of Southern California and a law degree with an emphasis in corporate finance.
He has spent decades working with companies across San Marino and the San Gabriel Valley, including Pasadena, on the contracts and partnerships that later turn into disputes. Reach out to talk through what’s happening in your business and what your options look like.

Business disputes rarely look the same twice, but most of them start with a broken agreement or a disagreement over money. We work with business owners, partners, and executives across Pasadena and the San Gabriel Valley on matters that include:
Each of these situations calls for a different approach, and the starting point depends on what the contract actually says and what happened between the parties.
What happens if you wait too long to act on a broken deal? In California, an action upon any contract, obligation, or liability founded upon an instrument in writing generally must be filed within four years under Code of Civil Procedure Section 337.
If the agreement was only spoken, that window shrinks to two years for a business contract, obligation, or liability not founded on a written instrument under Code of Civil Procedure Section 339. Some claims, such as disputes over the sale of goods, have a four-year window.
Miss either deadline, and the court can throw out your case no matter how strong the facts are.
Delay costs you in other ways too. Witnesses forget details, records get lost, and the other side gains time to move money or assets out of reach. A dispute that could have settled in months can turn into a drawn-out court fight if it sits too long before anyone acts on it.
Most business disputes do not start in a courtroom. They start with a letter laying out what happened and what is owed, followed by negotiation to see if the matter can resolve without a lawsuit.
When a case cannot settle, it moves into the Los Angeles County Superior Court. Disputes arising in Altadena, Arcadia, Monrovia, Pasadena, and Sierra Madre are generally filed through the Pasadena Courthouse, which handles civil cases for that part of the San Gabriel Valley.
With experience teaching business and commercial law part-time at California State University, Los Angeles, Robert Petrovich uses an approach grounded in how courts and commercial codes apply to everyday business decisions.
This practical background shapes how he evaluates contracts, partnership agreements, and commercial leases before advising clients on whether to negotiate, mediate, or file suit.
Most disputes rooted in Pasadena and the surrounding San Gabriel Valley are filed with the Los Angeles County Superior Court at the Pasadena Courthouse, located at 300 East Walnut Street. That courthouse handles civil matters for Pasadena, Altadena, Arcadia, Monrovia, and Sierra Madre, so a dispute rooted in one of these cities typically stays close to home rather than moving to downtown Los Angeles.
No. Partners and co-owners can bring claims against each other over money, control, or broken promises while the business keeps operating. Dissolving the company is a separate decision, and many disputes resolve, whether through negotiation or a lawsuit, without the business ever shutting down.
Not automatically, though many contracts include a clause requiring mediation or arbitration before either side can go to court. Even without that clause, many business disputes get worked out through direct negotiation before anyone files a lawsuit, since it is often faster and less expensive than a trial.
Costs vary based on the size of the dispute, how much is contested, and whether the case settles early or goes to trial. Fees are discussed directly so you know what to expect before deciding how to move forward.
Timelines depend on the complexity of the case and the court’s calendar, but straightforward contract disputes often resolve in under a year if both sides cooperate during discovery. Cases that go all the way to trial, or that involve multiple parties and complex accounting, can take considerably longer. If you’re weighing whether to send a demand letter or file suit, reach out and we can go over your situation together.
A business dispute does not get cheaper or simpler by waiting, and the deadlines described above do not pause while you decide what to do.
