What Does Sound Mind Mean in Legal Terms?

Definition & Meaning

A sound mind refers to a mental state in which a person is capable of reasoning and making judgments about ordinary matters, similar to other rational individuals. Legally, there is a presumption that anyone who has reached the age of majority is considered to have a sound mind, which means they are competent to enter into contracts and fulfill civil responsibilities. If someone claims they are not of sound mind, they must provide clear evidence to support this assertion.
