Under what condition can a contract with a minor stand?

A contract with a minor can stand if the minor chooses to honor the contract. In many legal systems, minors are afforded certain protections that allow them to enter into contracts but also provide them with the right to void those contracts if they choose. This means that while a contract can be valid, the minor has the ability to affirm it or reject it upon reaching the age of majority. When a minor decides to honor the contract, it effectively becomes enforceable, reflecting the minor's willingness to be bound by the terms.

The other options suggest requirements such as parental consent or needing the adult's agreement, which do not inherently validate the contract with a minor. Additionally, insisting that a contract be in writing is not a universal requirement for the validity of contracts involving minors. Hence, the focus on the minor's choice to honor the contract accurately captures the legal principle at play.
