Getting sued in San Diego is expensive even when you win. The difference between a case that settles in 90 days for nuisance value and one that runs three years and breaks the company is the law firm you hire in the first week.

What does a commercial litigation defense engagement cost in San Diego?
Commercial litigation defense in San Diego runs by matter complexity. A simple breach of contract case through summary judgment runs $75,000 to $250,000. Mid-complexity business tort cases through trial run $500,000 to $2M. Securities class actions and complex multi-party commercial disputes routinely cross $3M to $10M+. Emergency TRO and preliminary injunction work runs $50,000 to $200,000 for the first 30 days. Hourly rates at San Diego litigation boutiques sit at $450 to $850/hour; AmLaw 100 firms charge $700 to $1,400/hour for the same work.
What to expect from a San Diego commercial litigation defense engagement
A San Diego commercial case takes 14 to 24 months from filing to summary judgment, longer if discovery is contested. Add 6 to 12 months for trial. Emergency injunction hearings can be set within 3 to 30 days of an ex parte application depending on urgency. Discovery typically runs 9 to 14 months in San Diego Superior Court, slightly faster in federal court. Mediation usually happens in months 10 to 18; arbitration awards land 12 to 24 months from demand.
Red flags to watch for when picking a commercial litigation defense lawyer in San Diego
Guaranteed outcomes. No ethical attorney can guarantee a result. If a firm promises a specific recovery, dismissal, registration, or settlement number, walk away.
The disappearing partner. You meet a senior partner at intake, then never speak to them again. The case is handled by an unsupervised junior or a paralegal. Ask in writing who will be your day-to-day attorney.
Pressure to sign immediately. Reputable firms give you the retainer in writing, time to read it, and the option to take it home. High-pressure intake is almost always a sign of a volume mill, not a careful practice.
No verifiable track record. The firm should be able to point to deals closed, verdicts, settlements, peer rankings, or bar association recognition. “We’ve helped thousands of clients” is marketing copy. Specific numbers, named cases, and third-party rankings are evidence.
Vague fee terms. “Don’t worry about cost” is a red flag. Every legitimate San Diego lawyer will give you a written engagement letter with the fee structure, what’s covered, what triggers extra charges, and what happens if you fire them.
10 questions to ask in your free consultation
Most San Diego firms on this list offer a free initial consultation. Use it. Bring a list of questions and write down the answers. Compare across at least two firms before you sign.
Who, specifically, will handle my matter day-to-day? Get a name. Get an email.
How many matters like mine have you handled in the last three years? You want a number, not a brochure line.
What is your fee, and what does it cover? Get the answer in writing before you sign.
What expenses am I responsible for, and when? Out-of-pocket costs surprise people. Ask now.
What is the realistic range of outcomes for a matter like mine? A good lawyer will give you a range. A bad one will promise the high end.
How long will it take? Honest estimate, with the assumptions stated.
Who else might be involved? Experts? Co-counsel? Know who’s on the team.
How and how often will I hear from you? Email-only? Calls? Monthly updates? Set the expectation now.
What happens if I want to change lawyers later? Rules allow it; make sure you understand the mechanics.
What’s the worst-case outcome for my matter? A lawyer who refuses to discuss downside risk is selling you something.
What’s specific about a commercial litigation defense matter in San Diego
San Diego Superior Court vs. federal court. San Diego Superior Court runs faster than most California state courts but slower than the Southern District of California for federal matters. The choice of forum often drives outcome as much as the merits.
The 2024 case management orders matter. San Diego Superior Court has new case management orders post-pandemic that shorten discovery in unlimited civil cases. A defense lawyer who hasn't tried a case in San Diego in the last two years will miss the deadlines.
Cross-border discovery. Litigation involving Mexican parties is common in San Diego. Hague Convention requests, Mexican-court letters rogatory, and bilingual depositions add cost and time. A San Diego firm with this experience saves months.
The defense bar is small. San Diego's commercial litigation defense bar is roughly 200 attorneys at the top firms. Most know each other professionally — which usually means more reasonable meet-and-confer, faster scheduling, and lower discovery cost than out-of-town counsel.
Frequently asked questions
I just got served — how fast do I need a lawyer?
Today. You have 30 days from service to file a response in California Superior Court (21 days for federal court). Missing that deadline triggers default. Even if you think the case is frivolous, file something on time. Most San Diego litigation firms will take an emergency intake within 24 hours.
How much does it cost to defend a commercial lawsuit in San Diego?
Through summary judgment, expect $75,000 to $250,000 for a simple breach of contract case and $500,000 to $2M for a complex business tort. Through trial, double those numbers. Most San Diego firms will give you a written budget at the 60-day mark once they've seen the pleadings and initial discovery.
Should I file a motion to dismiss or just answer the complaint?
Depends on whether the complaint has a viable claim and whether you want to surface defenses early. A demurrer (motion to dismiss in California state court) can knock out weak claims before discovery, but it can also educate the plaintiff. A San Diego litigation defense attorney will tell you whether the motion is worth filing in the first week.
What is a PAGA notice and why did we get one?
A Private Attorneys General Act notice is a precursor to a wage-and-hour representative action. If you got one, you have a short window to investigate and potentially cure the alleged violations. Call a San Diego employment defense attorney immediately — this is not a regular commercial case.
Can I sue the plaintiff back?
Often yes. A defendant can file a cross-complaint for related claims against the plaintiff or third parties. Compulsory cross-complaints (related to the same transaction) must be filed at the time of your answer or you lose them. A San Diego litigator will run the analysis in the first week.
My insurance company appointed a panel attorney — do I have to use them?
If the insurer's reservation of rights creates a conflict of interest, California Civil Code §2860 (Cumis counsel) lets you pick independent counsel paid by the carrier at a court-approved rate. A San Diego firm familiar with Cumis will get the right counsel appointed without losing coverage.
How do I respond to an emergency TRO motion?
Drop everything. You typically have 24 to 72 hours to file opposition papers and prepare for hearing. Most San Diego defense firms have an on-call partner for emergency TRO work. Cost runs $25,000 to $100,000 in the first week.
Can we settle quietly without filing a response?
Sometimes. Pre-answer settlement is possible if the plaintiff is open to it and the demand is reasonable. But you still must protect the deadline — either get a written extension from opposing counsel or file a protective answer. A San Diego litigation attorney will manage the timeline while settlement talks proceed.
One last thing. Choosing a lawyer is personal. Read the reviews. Call two or three firms before you sign. Ask each one: How many matters like mine have you handled in the last three years? The answer tells you everything. — The LawFirmSquare team
