You're finally about to close the deal. Months of late-night emails, Zoom calls that should have been emails, and grueling negotiations have led to this moment. The contract is sitting on the desk. Then, out of nowhere, a competitor swoops in. They don’t just offer a better price; they actively pressure your client to rip up your agreement. It feels dirty. Honestly, it usually is. In the legal world, we call this intentional interference with contractual relations, and it’s one of those "business torts" that can turn a friendly rivalry into a multi-million dollar courtroom drama.
Business is competitive. We get that. But there is a very real, very sharp line between aggressive poaching and illegal sabotage. If you cross it, you aren't just a "disruptor"—you're a defendant.
What People Get Wrong About Intentional Interference With Contractual Relations
Most people think you can only sue someone if they break a contract with you. That's a standard breach of contract. This is different. Intentional interference with contractual relations involves a third party—a meddler—who convinces someone else to break their promise to you.
It’s about the "intermeddler."
For a claim to actually hold water in court, you usually need to prove a few specific things. First, a valid contract had to actually exist. You can't interfere with a vibe or a "maybe." Second, the person doing the interfering had to know about that contract. If they were totally oblivious, you’re probably out of luck. Third, they had to intend to induce a breach. Accidental interference isn't really a thing here. Finally, you have to show that their meddling actually caused the breach and resulted in you losing money.
The "Malice" Factor
Lawyers argue about "malice" constantly. In some states, like California or New York, the courts look at whether the interference was "wrongful by some measure beyond the interference itself." Basically, did they use dishonest means? Did they lie? Did they threaten the person? If a competitor just offers a better deal, that’s usually just capitalism. If they tell your client that you’re secretly bankrupt (when you aren't) just to make them jump ship, that’s where the trouble starts.
Real World Messiness: The Pennzoil v. Texaco Disaster
If you want to see how high the stakes get, look at the 1980s battle between Pennzoil and Texaco. This is the "Godfather" of intentional interference cases.
Pennzoil had a "handshake" deal (which was legally binding in this context) to buy a huge chunk of Getty Oil. Texaco saw the deal, didn't like it, and decided to swoop in with a higher offer, effectively baiting Getty Oil to snub Pennzoil.
Pennzoil sued.
They didn't just win; they won big. A Texas jury awarded Pennzoil $10.53 billion. At the time, it was the largest civil verdict in U.S. history. Texaco had to file for Chapter 11 bankruptcy just to stay alive while they appealed. It’s a massive reminder that even in the "greed is good" era, the law expects a certain level of respect for existing deals.
When Is "Interference" Actually Legal?
Not every interruption of a contract is a crime or a tort. Sometimes, people have a "privilege" to interfere.
Imagine a lawyer advising a client to break a contract because that contract is actually illegal. That’s protected. Or consider a parent advising a child to back out of a predatory talent scout agreement. Courts generally don’t want to punish people for giving honest, good-faith advice.
The Competition Privilege
This is where it gets sticky. In a free market, we want companies to compete. If a contract is "at-will"—meaning either party can leave at any time—competitors have a lot more leeway to lure customers away.
However, if there is a fixed-term contract (say, a three-year exclusivity deal), the "competition privilege" mostly disappears. You can't just walk into a room and convince someone to break a fixed-term lease or a multi-year service agreement just because you want the business. That’s crossing the line from "competing" to "sabotaging."
The Damage Isn't Just "Lost Profits"
When you sue for intentional interference with contractual relations, you aren't just looking for the money you would have made.
- Compensatory Damages: This is the obvious stuff. If the contract was worth $500,000, you want that money.
- Consequential Damages: Maybe losing that contract caused a chain reaction that made you lose other clients. You can sometimes chase those losses too.
- Punitive Damages: This is the scary part for defendants. If the interference was especially nasty or spiteful, a judge or jury might tack on extra millions just to punish the meddler and make an example out of them.
Proving the "Intent" in Intentional Interference
How do you prove what someone was thinking? You can't read their mind.

Usually, it comes down to the "paper trail." In 2026, that means Slack messages, deleted Signal chats (which aren't always as deleted as you think), and internal emails. If a manager sends an email saying, "I know they have a deal with Company X, but let's see if we can squeeze them until they break it," that’s the smoking gun.
Courts also look at the timing. If a client cancels their contract with you at 10:00 AM and signs with your rival at 10:05 AM, it doesn't take a genius to figure out what happened behind the scenes.
A Note on "Prospective" Relations
There is a cousin to this legal claim called "Intentional Interference with Prospective Economic Advantage." This is for when a contract hasn't been signed yet, but there was a "reasonable probability" that it would have been. This is much harder to win. You have to prove the defendant did something independently wrongful—like defamation or physical threats—to blow up the budding deal.
Defensive Strategies: Protecting Your Deals
If you’re running a business, you can't just sit around and hope people play fair. You need to be proactive.
First, make sure your contracts are crystal clear about their duration and the penalties for leaving early. If a third party sees a "liquidated damages" clause, they might realize that poaching your client will cost more than it's worth.
Second, if you suspect a competitor is whispering in your client's ear, send a "Notice of Contract" letter to the competitor. Once they have formal, written notice that a contract exists, they can no longer claim they were "just accidentally" interfering. You’ve officially put them on the hook for intentional interference with contractual relations if they keep pushing.
The Role of Modern Technology
We're seeing a lot of these cases pop up in the tech world lately, specifically regarding "poaching" entire engineering teams.
When a company hires one person from a rival, that's fine. When they hire an entire 20-person department specifically to kill a rival's product launch, that looks a lot like intentional interference. We saw glimpses of this during the various legal battles between ride-sharing giants and autonomous vehicle startups. The "trade secret" theft usually gets the headlines, but the underlying interference with employment contracts is often where the real damage is calculated.
Practical Steps to Take Right Now
If you think someone is messing with your business contracts, don't just send an angry text. It rarely helps.
- Secure your evidence immediately. Save every email, voicemail, and text from the client who is wavering. Look for mentions of the third party.
- Review the "Inducement." Did the competitor offer a standard discount, or did they offer to "pay the legal fees" if your client gets sued for breaching? That last one is a massive red flag for intentional interference.
- Check your non-solicitation clauses. If the person interfering is a former employee, you might have a much easier path to victory through their own restrictive covenants.
- Consult a litigator who specializes in "Business Torts." This is a specialized niche. General corporate lawyers might miss the nuances of proving "wrongful means" in your specific jurisdiction.
- Evaluate the "Causation." Be honest with yourself—was the client going to leave anyway? If the relationship was already dead, it’s much harder to blame the competitor for the final breakup.
The reality is that intentional interference with contractual relations happens every day. Most of the time, it's settled with a stern letter or a small payout. But when it's blatant, and when the money is significant, the law provides a very powerful hammer to keep the marketplace honest. Competition is good. Sabotage is expensive.
