Which group of individuals is considered not to have legal capacity in the context of contracts?

In the context of contracts, individuals who lack legal capacity are often those who cannot fully understand the nature and consequences of their actions when entering into an agreement. This includes both children and minors, as they are generally considered incapable of entering into binding contracts due to their age and the presumption that they may not fully grasp the implications of their actions.

Similarly, insane individuals, or those who are mentally incapacitated, are also recognized as lacking the legal capacity to form valid contracts. Their mental state can impair their ability to understand and consent to the terms of a contract.

Thus, the answer that combines both groups—children and minors, alongside insane individuals—accurately reflects those who are deemed to have no legal capacity in the context of contracts, making it the correct choice.
