Most business relationships start with good intentions. A signed contract, a handshake, an agreement about how work gets done and how money gets paid. For the majority of these arrangements, things proceed as expected. But not always.
When a business partner stops contributing and starts diverting, when a vendor takes your money and disappears, when a competitor interferes with a client relationship they had no right to touch, the damage is real. And a strongly worded demand letter often does not fix it.
Commercial litigation is the legal process for resolving business disputes through the courts. It is not fast, it is not cheap, and it is not always the right answer. But when the amount at stake is significant and the other party refuses to act fairly, it can be the most effective tool available for protecting what you have built.
This guide explains what commercial litigation in South Carolina involves, when it makes sense, what you can expect from the process, and why the decision to pursue a claim should not wait.
Commercial litigation is civil litigation between businesses, or between individuals over business-related matters. It covers a wide range of disputes, including contract enforcement, fraud, partnership conflicts, fiduciary duty breaches, and competitive interference.
Unlike personal injury cases, which typically involve individuals and insurance companies, commercial disputes often involve contracts with specific terms, financial records, corporate entities, and relationships between parties who have been doing business together for months or years.
The core of most commercial litigation is a legal wrong that caused financial harm. The plaintiff, the party bringing the case, argues that the defendant acted in a way that violated a legal duty owed under a contract or under the law itself, and that the plaintiff suffered economic damages as a result.
At Berly Rouse, we represent plaintiffs in commercial disputes. We do not defend corporate interests against valid claims. Our clients are businesses and individuals who have been wronged, and our goal is to pursue accountability and recovery on their behalf.
The Lowcountry’s growing business environment produces a consistent range of commercial conflicts. The following are the most common we see in Mount Pleasant, Charleston, and across the region.
A breach of contract occurs when one party fails to fulfill their obligations under a binding agreement. It is the most common commercial dispute by volume. Breaches can take many forms:
In South Carolina, the general statute of limitations for breach of a written contract is three years from the date of the breach. For oral contracts, it is also three years. These deadlines can be affected by discovery rules, tolling provisions, and the specific terms of the agreement, which is why consulting an attorney promptly matters.
To succeed on a breach of contract claim, the plaintiff must show that a valid contract existed, that they performed their own obligations, that the defendant breached the agreement, and that the breach caused damages.
Business fraud occurs when someone makes a false statement of fact, knowing it is false, to induce another party to enter a transaction or part with money. Misrepresentation cases sometimes involve a defendant who genuinely believed what they said was true but was reckless in making the claim.
Common examples include:
Fraud claims require more specific proof than breach of contract and involve their own procedural requirements. They also carry the possibility of punitive damages in some circumstances, which contract claims do not.
Business partner conflicts are among the most contentious and financially significant disputes we handle. When co-owners disagree, deadlock, or one party begins acting in their own interest at the expense of the business, the damage can escalate quickly.
Partnership and LLC disputes frequently involve:
South Carolina law imposes fiduciary duties on business partners and LLC members in managing roles. When those duties are violated, the injured party may have a claim for damages and, in some cases, equitable relief including forced buyout or dissolution.
When a key employee, contractor, or former partner is bound by a non-compete or non-solicitation agreement and violates its terms, litigation may be the only practical remedy. These cases often move quickly because the harm is ongoing and may require injunctive relief to stop.
South Carolina courts will enforce non-compete agreements that are reasonable in scope, duration, and geographic reach. The question of enforceability is highly fact-specific, and how the agreement was drafted matters enormously.
Mount Pleasant and the broader Charleston market have seen significant commercial real estate activity. With that activity comes disputes: landlords and tenants disagreeing over lease terms, maintenance obligations, CAM charge calculations, defaults, and early terminations. These cases are governed by the terms of the lease and South Carolina property law, and the financial stakes can be substantial.
When a competitor, former employee, or another party intentionally interferes with a business relationship or contract in a way that is improper or unlawful, that conduct can give rise to a tortious interference claim. Proving these cases requires showing that the defendant had knowledge of the existing relationship and acted specifically to disrupt it.
Not every disagreement needs to go to court. Many disputes are resolved through negotiation, mediation, or arbitration, which is often faster, less expensive, and less adversarial than full litigation. South Carolina courts also encourage alternative dispute resolution, and many commercial contracts include mandatory arbitration clauses.
Litigation makes the most sense when:
The decision to litigate requires an honest assessment of the strength of the evidence, the realistic value of the claim, and what outcome you are actually trying to achieve. A capable attorney will give you that assessment plainly, including the risks, before you commit.
Commercial litigation in South Carolina follows the general framework of civil litigation in the state court system, with cases typically filed in the Court of Common Pleas in the county where the dispute is based. For Mount Pleasant businesses, that generally means Charleston County.
Here is a high-level overview of how the process works:
Before filing suit, your attorney will review the relevant contracts, communications, and financial records to assess the strength of your claims. In many cases, a formal demand letter will be sent before litigation is initiated. Some disputes resolve at this stage.
If the demand does not produce resolution, your attorney files a complaint with the court. The complaint lays out the factual allegations and the legal claims being asserted. The defendant is then served and has a set period to respond.
Discovery is the process of exchanging evidence. It includes written interrogatories, document requests, and depositions. In commercial cases, discovery can involve significant volumes of financial records, contracts, email and text communications, and corporate documents. Discovery often takes months and is where a significant portion of case costs accumulate.
Both sides may file motions asking the court to rule on legal issues before trial. Summary judgment motions, which ask the court to decide the case without a trial based on the undisputed evidence, are common in commercial cases where legal questions are central.
South Carolina courts typically require parties to attempt mediation before trial. Mediation is a structured negotiation session facilitated by a neutral third party. The majority of commercial cases resolve at or before mediation, which makes it a meaningful stage in the process.
If the case does not settle, it goes to trial. Commercial cases can be tried before a judge, a jury, or in some contractual settings, an arbitrator. Trial is the most time-intensive and expensive phase of litigation, and cases that proceed to this point have typically involved significant disputes about both the facts and the law.
In commercial litigation, most large law firms represent both plaintiffs and defendants, often depending on who pays more. At Berly Rouse, we only represent plaintiffs. That focus shapes everything about how we approach cases.
Our incentive is to recover for the clients who have been harmed, not to manage risk for the companies doing the harming. We evaluate cases from the perspective of what accountability looks like for the wronged party, and we are willing to take cases to trial when that is what achieving justice requires.
This is especially important in commercial cases where the opposing side may be a well-funded company with internal legal teams and external counsel whose entire job is to delay and minimize claims. Having counsel that is prepared to match that effort and take the case the distance changes the dynamic considerably.
South Carolina’s statute of limitations for most contract-based claims is three years. The clock generally starts from the date of the breach. For fraud and misrepresentation claims, the limitations period is also typically three years, running from the date the fraud was discovered or should have been discovered through reasonable diligence.
Missing the deadline generally bars the claim permanently, regardless of how strong it is. Courts have little discretion to extend filing deadlines in most circumstances. If you believe you have a commercial dispute, consulting an attorney quickly is essential.
Do I need a lawyer to file a business lawsuit in South Carolina?
Individuals may represent themselves in South Carolina courts, but commercial cases are rarely simple enough for self-representation to be effective. Discovery, motion practice, and the procedural rules of civil litigation require legal knowledge and experience. Attempting to handle complex commercial litigation without an attorney puts you at a significant disadvantage against a represented opponent.
Can I sue a former business partner for taking clients?
Potentially, yes. If a former partner was bound by a non-solicitation agreement, a breach of fiduciary duty claim, or both, and they took clients or diverted business opportunities in violation of those obligations, you may have viable claims. The strength of the case depends heavily on what agreements existed and what evidence is available.
What if my contract has an arbitration clause?
Many commercial contracts require disputes to be resolved through binding arbitration rather than court litigation. Arbitration is a private process that is often faster and more confidential than court proceedings, but it has its own rules and limitations. Your attorney can review the clause to determine what it covers, whether it is enforceable, and what process would apply to your dispute.
How much does commercial litigation cost?
Costs vary significantly depending on the complexity of the case, the amount of discovery involved, and whether the case goes to trial. At Berly Rouse, we discuss fee arrangements clearly at the outset so you understand what to expect. We handle some commercial cases on a contingency basis where the structure of the claim makes that appropriate.
What is the difference between commercial litigation and a demand letter?
A demand letter is a written communication to the other party outlining your claim and requesting specific action or payment. It is often a precursor to litigation, and some disputes resolve at this stage. Litigation means filing a formal lawsuit in court. Your attorney will advise on whether a demand letter is the right first step given the specific facts and the nature of the relationship with the opposing party.
