An infant, which is defined as a person under the age of 18, is generally considered legally incapable of entering into a contract. This is because they do not have the legal capacity to fully comprehend the terms and implications of the agreement they are entering into. However, there may be certain circumstances where an infant can enter into a contract.

One of the main reasons why infants are considered legally incapable of entering into a contract is because of their lack of mental capacity. They are not able to fully understand the rights and obligations that come with entering into an agreement, nor are they able to fully comprehend the consequences of breaching the contract. This puts them at a disadvantage compared to adults who have more experience and knowledge of contractual agreements.

Another reason why infants are not usually allowed to enter into contracts is because of their protection under the law. The law recognizes that infants are vulnerable and therefore, they need to be protected from being taken advantage of by adults. If an infant were allowed to enter into a contract, they could be easily manipulated or coerced into agreeing to terms that are not in their best interest.

However, there are certain circumstances where an infant can enter into a contract. In general, an infant can enter into contracts that are for their benefit, such as a contract for medical treatment or education. This is because these agreements are necessary for the well-being and development of the infant.

Additionally, an infant can enter into a contract if it is ratified or approved by their legal guardian. This means that the parent or guardian of the infant agrees to be bound by the terms of the contract on behalf of the infant.

In conclusion, an infant is generally not legally capable of entering into a contract. They lack the mental capacity and legal protection necessary to fully understand and agree to contractual obligations. However, there may be certain circumstances where an infant can enter into a contract, such as when it is for their benefit or when it is ratified by their legal guardian. As always, it is important to seek legal advice if you are unsure about the legality of a contractual agreement involving an infant.
