Final answer:
An emancipated minor generally has the legal capacity to enter into a valid and enforceable real estate sales contract, as emancipation grants them the same contractual rights as an adult.
Step-by-step explanation:
A real estate sales contract entered into by an emancipated minor is generally considered valid and enforceable. Emancipation grants minors most of the legal rights of an adult, which includes the right to enter into contracts. In the context of real estate, individuals or firms must own the property to enter into a contract. Hence, an emancipated minor who owns property has the legal capacity to engage in contracts regarding that property, including sales contracts.
