Breach of Fiduciary Duty in South Carolina: What It Is and When Misappropriation Becomes a Claim

Aug 25, 2026 | Blog, Commercial Litigation, Estate Litigation

Someone notices that the numbers do not reconcile. A business partner has been moving money through an account nobody else reviews. A trustee has sold property to a relative at a price that would not survive an appraisal. A client’s settlement funds sat in a trust account and came out smaller than they went in.

The instinct in each of these situations is to ask whether what happened was illegal. That is usually the wrong first question. The more useful question is whether the person holding the money owed a fiduciary duty, because that duty is what turns a troubling decision into a claim someone can actually bring.

Here is what a fiduciary duty is under South Carolina law, who owes one, what misappropriation of funds means, and how to tell a poor decision apart from a breach worth pursuing.

What is Fiduciary Duty?

A fiduciary duty is the obligation one person owes another when they have been entrusted with that person’s money, property, or interests. It is the strictest standard the civil law imposes, and it is meaningfully different from an ordinary contractual obligation.

Under a contract, each side is entitled to look after itself. A fiduciary cannot. The fiduciary is required to place the other party’s interests ahead of their own, and the duty holds even where the fiduciary would have preferred a different arrangement and even where nothing in writing spells it out.

That distinction is the whole analysis in many of these matters. A business decision that turned out badly is not a breach. The same decision made by someone who quietly stood to gain from it very often is.

Who Owes a Fiduciary Duty

Fiduciary relationships arise in more settings than people expect, and the label does not have to appear anywhere for the duty to exist. In South Carolina the relationship is generally established by the facts of the arrangement rather than by what the parties called it.

Trustees and the beneficiaries of the trusts they administer. Executors and personal representatives, who owe the duty to the beneficiaries of an estate rather than to the family member who nominated them. Corporate officers and directors, who owe it to the company and its shareholders. Business partners and the managing members of an LLC, who owe it to one another. Agents acting under a power of attorney, who owe it to the person who signed it. Attorneys, who owe it to their clients. And in some circumstances an employee entrusted with company funds or confidential information.

For the professionals who advise these people, that breadth is the practical point. If a client of yours is holding somebody else’s money in any capacity, the duty is probably in play, and the standard they are being held to is higher than they likely realize.

The Four Duties a Fiduciary Owes

Courts describe the obligation in different ways depending on the setting, but four components come up consistently and they are worth separating because a breach usually involves only one of them.

Loyalty. The fiduciary cannot use the position for personal benefit and cannot act where their own interest conflicts with the interest they are supposed to be serving. Undisclosed conflicts fall here, and so does taking an opportunity that belonged to the business or the estate.

Care. The fiduciary has to manage the property prudently. This is the duty that reaches carelessness rather than dishonesty, and it is the reason a fiduciary who simply is not doing the work can be liable without ever taking a dollar.

Impartiality. Where there are multiple beneficiaries or shareholders, the fiduciary has to treat them according to the terms of the instrument or the agreement rather than according to personal preference.

Disclosure and accounting. The people owed the duty are entitled to know what is held and what has happened to it. A fiduciary who will not answer that question has created a problem regardless of whether the underlying numbers turn out to be sound.

What Misappropriation of Funds Means

Misappropriation of funds is the use of money by someone who was lawfully entrusted with it for a purpose that person was not authorized to use it for. The distinction that matters is that the funds arrived legitimately. Nobody took anything by force or deception at the outset, which is what separates misappropriation from ordinary theft and what makes it harder to spot.

In practice it tends to look like one of a few things. Funds moved from a business account to cover a personal obligation, with an intention to repay that may well be sincere. Estate or trust assets used by the fiduciary before the distribution is finalized. Client funds held in a trust account and drawn against for something other than that client’s matter. Company money routed through a related entity the other owners were never told about.

Intent to permanently deprive is not always required, which surprises people. Funds borrowed and returned can still constitute a breach, because the duty was to hold the money for a specific purpose and not to use it as a personal line of credit. This is also the point at which a civil claim may exist alongside a separate regulatory or criminal exposure, and those tracks move independently of one another.

Where These Breaches Show Up

The same duty produces very different cases depending on the setting, which is why these matters are frequently misfiled at the outset.

In a business, it surfaces as a partner or officer taking compensation nobody approved, diverting an opportunity to a company they own separately, or running personal expenses through the books. The other owners usually discover it while looking at something unrelated.

In an estate or a trust, it surfaces as a personal representative or trustee selling assets to themselves or to family, distributing on a schedule that favors one beneficiary, or going quiet when asked for an accounting. Delay by itself can be a breach, and beneficiaries are not required to wait indefinitely.

Where an attorney is involved, the analysis moves into professional liability as well. An attorney holds client funds under both a fiduciary duty and the rules of professional conduct, and a shortfall in a trust account raises questions on both tracks at the same time. Where that has happened, the civil claim and the professional obligation have to be evaluated together rather than in sequence.

What a Claim Requires

A breach of fiduciary duty claim in South Carolina generally requires establishing that a fiduciary relationship existed, that the fiduciary breached one of the duties the relationship carries, and that the breach caused a measurable loss.

The first element is contested more often than people expect. A defendant’s first move is frequently to argue that the relationship was an ordinary business or contractual one, carrying no fiduciary obligation at all. Establishing the relationship is therefore not a formality, and it usually rests on evidence about how the arrangement actually operated rather than on how it was labeled.

The records are what decide these cases. Account statements, transfers, minutes, correspondence, and accountings either support the transaction or they do not, and a documentation gap frequently tells the story more clearly than the documents themselves. Before a matter is worth filing, it is worth knowing what can be obtained and what has already been lost.

Timing and Why These Matters Should Not Sit

South Carolina imposes filing periods on breach of fiduciary duty claims, and when the clock begins can depend on when the breach was or reasonably should have been discovered. Because these breaches are frequently concealed by the one person positioned to conceal them, the discovery question is often litigated before anything else in the case.

The practical consequence is that timing gets evaluated first. Records also become harder to obtain as time passes, accounts get closed, and the people who could explain a transaction move on. A matter that looks strong on the facts is not a matter at all once the window has closed, so the timing question is the one to raise at the first conversation rather than the third.

What to Expect When You Reach Out

When a potential breach of fiduciary duty matter comes to us, we look at the timing first, then at whether the relationship supports the duty, then at what the records will show, and finally at whether the loss can be quantified in a way that justifies the cost of litigation.

We will tell you directly whether we think a matter is worth pursuing. When our answer is that it should not be filed, we say so plainly, and we would rather give you that answer than open a file that goes nowhere.

If you are an attorney, a CPA, or an advisor bringing us a situation involving a client, the same process applies and you will be speaking with a partner rather than an intake coordinator. Your relationship with your client stays intact, you are kept informed, and nothing about the referral puts you in a position you did not agree to. When you refer a case to us, your name is on it too, and we handle it accordingly.
