Final answer:
Kelly being a minor when she signed the lease does matter. The specific laws regarding minors and contracts can vary depending on the jurisdiction. It is advisable for Kelly to consult with a lawyer to understand her rights and obligations.
Step-by-step explanation:
Yes, Kelly being a minor when she signed the lease does matter. In most jurisdictions, contracts entered into by a minor are voidable by the minor, meaning they can choose to enforce or nullify the contract once they reach the age of majority. However, there may be exceptions to this rule, such as when a minor enters into a contract for necessities like food and shelter.
In this case, Kelly signed the lease when she was 17 but moved in after her 18th birthday. Since she started paying rent after she turned 18, it can be argued that she ratified the lease and is bound by its terms. However, the specific laws regarding minors and contracts can vary depending on the jurisdiction, so it would be advisable for Kelly to consult with a lawyer to understand her rights and obligations.
