In Wisconsin, the legal age to sign a contract is 18 years old. This means that individuals who have not yet reached the age of 18 are considered minors and do not have the legal capacity to enter into binding agreements on their own.

However, there are some exceptions to this rule. For example, minors who are emancipated or have been granted legal status as an adult may be able to sign contracts on their own. Additionally, minors may be able to enter into contracts with the consent of their parents or guardians.

It is important to note that contracts entered into by minors without proper authority may be deemed unenforceable. This means that parties may not be able to hold each other accountable for the terms of the contract. As a result, it is crucial to ensure that all parties involved in a contract are of legal age and have the necessary authority to enter into the agreement.

If you are unsure about the legal age to sign a contract or have questions about the enforceability of a contract involving a minor, it is always best to seek the advice of a qualified legal professional. An attorney who is experienced in contract law can help ensure that your interests are protected and that your agreements are legally binding.
