You just got served with a lawsuit from your business partner. Maybe you saw it coming, perhaps with months of tension, disagreements about money, or diverging visions for the company. Or maybe it blindsided you completely.
Either way, you now have deadlines, decisions to make, and a business that still needs to run while all of this plays out. Your next few weeks matter more than you might think.
If you're facing a partnership dispute in California, call us today to discuss your situation and understand your options.
Key Takeaways for What to Do If a Business Partner Sues You in California
- You have 30 days to respond, and missing that deadline can end your case before it starts. In California, failing to file a timely response can result in a default judgment, meaning the court rules against you without hearing your side. Confirm your exact deadline immediately.
- What you do in the first few weeks matters more than you think. Don't delete documents, move money out of business accounts, or badmouth your partner to employees and clients. All of these can hurt your case or create new claims against you.
- The business still needs to run while this plays out. Figure out early who controls the bank accounts, who makes day-to-day decisions, and whether you need court orders to prevent your partner from causing damage during litigation.
How Long Do You Have to Respond?
In California, you typically have 30 days from the date you were served to file a response to the complaint. If the court serves you through substituted service—meaning the server left the papers with someone else at your home or business, or mailed them to you—you may have a few extra days, but do not assume you have an extension. Confirm your deadline immediately with your lawyer.
Missing this deadline can result in a default judgment, which means the court rules against you without ever hearing your side. Everything else in your case flows from getting this right.
What Should You Avoid Doing Right Now?
The period immediately after being sued is when people make mistakes that damage their case. A few things to keep in mind:
- Don't delete emails, texts, or documents. Once litigation begins, you have a legal duty to preserve evidence. Deleting anything, even if it seems irrelevant, can result in sanctions or allow the court to assume the deleted material was harmful to your case.
- Don't move money out of business accounts. Transferring funds, paying yourself a sudden bonus, or shifting assets to family members can look like you're trying to make yourself judgment-proof. Courts take a dim view of this, and it can hurt your credibility.
- Don't vent about your partner to employees, clients, or vendors. Anything you say can become evidence. Inflammatory statements can undermine your position or even expose you to a defamation claim.
- Don't try to force your partner out of the business unilaterally. Unless your partnership agreement gives you clear authority to do so, taking aggressive action to exclude your partner can backfire and become the basis for additional claims against you.
What Is Your Partner Actually Alleging?
The complaint will spell out the specific claims against you. Read it carefully, as it tells you what you're defending against and may also reveal weaknesses you can exploit. Common allegations in partnership disputes include:
- Breach of contract. Your partner claims you violated the terms of your partnership agreement—how profits were split, how decisions were made, how a buyout was supposed to work, or something else the agreement addressed.
- Breach of fiduciary duty. Under California Corporations Code § 16404, partners owe each other duties of loyalty and care. Your partner may allege you put your own interests ahead of the partnership's, such as diverting a business opportunity for yourself, misusing partnership funds, or engaging in self-dealing.
- Accounting. A formal demand for a complete accounting of the partnership’s finances often arises when a partner suspects misconduct, such as when a business partner takes too much money out of the business, hides revenue, or mismanages the books.
- Dissolution. A request for the court to wind up the partnership entirely and divide its assets.
Do You Have Counterclaims?
Lawsuits between partners frequently involve fault on both sides. If your partner breached the partnership agreement, violated their fiduciary duties, or harmed the business, you may be able to file counterclaims against them.
Some possibilities to consider:
- Your partner failed to contribute capital or labor as the agreement required.
- Your partner made unauthorized decisions that damaged the business.
- Your partner diverted business opportunities or competed against the partnership.
- Your partner is actually the one who breached their fiduciary duties—not you.
Counterclaims shift leverage. In some cases, they result in a net recovery in your favor even though you were the one originally sued.
How Will the Business Operate During Litigation?
One of the hardest parts of partnership litigation is that you may need to keep working alongside (or at least coexisting with) the person suing you. Questions to address early:
- Who controls the bank accounts? If both partners have signatory authority, consider whether safeguards are needed to prevent one partner from draining accounts while the case is pending.
- Who makes day-to-day decisions? If your partnership agreement doesn't address this clearly, you may need to ask the court for a temporary order clarifying who has management authority during the dispute.
- Is your partner actively harming the business? If they're transferring assets, poaching clients, or breaching non-compete obligations, you may need emergency court relief—a temporary restraining order or preliminary injunction—to stop the damage.
- Should the court appoint a receiver? In extreme situations, a court can appoint a neutral third party to manage the business while the dispute is resolved. This is a last resort, but it's an option when the partners can't function together at all.
Frequently Asked Questions
What if we don't have a written partnership agreement?
Your partnership will be governed by California's Revised Uniform Partnership Act (RUPA), which provides default rules for profit sharing, management authority, and dissolution. These defaults assume partners share everything equally, which may or may not reflect how you actually operated. This is a situation where having a lawyer will become particularly important.
Can I still run the business while we're suing each other?
Usually yes, but it depends on your partnership agreement and what's being alleged. If there's a risk your partner will harm the business during litigation, you may need court orders protecting the company's assets and operations.
Should I try to settle or fight this out?
That depends on several factors: the strength of your defenses, whether you have viable counterclaims, how much litigation will cost, and what outcome you're ultimately trying to achieve. Some disputes are worth fighting; others are better resolved quickly so everyone can move on. We can help you evaluate your options realistically.
What if my partner is trying to freeze me out?
If your partner is taking unilateral action to exclude you—such as changing locks, removing your access to accounts, or telling employees or clients you’re no longer involved—document everything and consult a partnership disputes attorney immediately. Situations where a business partner is trying to push me out may require emergency relief from the court to protect your rights.
What's an anti-SLAPP motion, and does it apply to my case?
California's anti-SLAPP statute allows defendants to quickly dismiss lawsuits that target free speech or petitioning activity. It applies in limited circumstances, typically when the claims arise from statements made in a public forum or about a matter of public interest. If it applies, it can end litigation early and allow you to recover your attorney's fees. Most partnership disputes don't qualify, but some do.
Should we try mediation or arbitration?
Many partnership agreements require partners to attempt mediation or arbitration before filing a lawsuit. These alternative dispute resolution (ADR) methods allow partners to resolve their disagreements confidentially and potentially faster and cheaper than litigation.
Even if your agreement does not require it, your lawyer may ask you to consider early mediation. A neutral third party helps both sides negotiate a settlement, giving you control over the outcome instead of leaving the decision to a judge.
How much does it cost to defend a partnership lawsuit?
The cost of litigation depends heavily on the complexity of the claims and how aggressively both sides fight. Costs include attorney's fees, court filing fees, and expenses for discovery (depositions, document requests).
The most significant factor influencing cost is time. Disputes that settle early cost far less than those that proceed to trial.
An experienced partnership litigation attorney provides a realistic assessment of potential costs based on your specific case and will do their best to resolve it efficiently while protecting your business interests
Is there a deadline for my partner to file a lawsuit?
Yes. California law sets a time limit, known as the statute of limitations, for your partner to file a lawsuit depending on the legal claim. For example, a claim for breach of a written contract usually has a four-year statute of limitations. For an oral contract, the limit is two years. A breach of fiduciary duty claim typically has a four-year limit but can vary depending on the specific facts of the case. Your lawyer determines if the statute of limitations expired, which gives you a complete defense against the claim.
