When you hire a lawyer, you trust them to put your best interests first. In Missouri, this trust forms what is known as a fiduciary duty. If a lawyer breaks this duty, it may qualify as legal malpractice. Understanding what counts as a breach of fiduciary duty helps you recognize when an attorney may have crossed the line.
The meaning of fiduciary duty
Fiduciary duty means your lawyer must act with honesty, fairness, and loyalty toward you. They cannot put their own interests above yours or make choices that harm your case for personal gain. This duty covers everything from handling your case strategy to managing your funds.
Common examples of breach
Several actions can count as a breach of fiduciary duty in Missouri. One example is when a lawyer represents two clients with opposing interests without disclosing the conflict. Another example is misusing or failing to safeguard client funds. A lawyer may also breach their duty if they reveal confidential information that damages your case.
How courts view breaches
Missouri courts look at whether the lawyer’s behavior placed their interests above the client’s. To prove a breach, you must show that the lawyer’s actions went against their duty of loyalty or care and that these actions harmed you. The court may consider financial harm, case outcomes, or even loss of trust as part of the damage.
When a lawyer breaches fiduciary duty, it can damage both your legal case and your confidence in the system. Recognizing these breaches gives you the ability to take steps to protect your rights. If your lawyer failed to act in your best interest, you may have a valid claim for legal malpractice.
