Who bears the burden of proof when seeking to void a contract due to lack of mental capacity?

In a situation where a party seeks to void a contract due to lack of mental capacity, it is the responsibility of the party making the claim—that is, the party seeking to void the contract—to provide evidence supporting their assertion. This requirement is grounded in legal principles that place the onus of proving claims on the individual making them, in this case, the party asserting they lacked the mental capacity to enter into the contract.

This burden of proof involves demonstrating that at the time of the contract's formation, they were unable to understand the nature and consequences of their actions, rendering them incapable of making an informed decision. Without presenting sufficient evidence to substantiate their claim, the court may be unable to grant relief, and the contract may remain enforceable.

Understanding the nuances of contract law, especially surrounding mental capacity, is essential in determining the outcome of such cases, as it acknowledges the legal status of individuals who may not fully comprehend their contractual commitments.
