Ronaldo purchased a car from Denton Auto Sales for $12,000 when he was 20 years and 4 months old. Ronaldo later returned the car to Denton Auto Sales, informing the dealership that he did not feel the car was a “good fit” for him and that he wanted his money back. At the time of disaffirmance, Ronaldo had just turned 21, the age at which he is considered an adult in his jurisdiction. 

Will Ronaldo's disaffirmance be enforceable in a court of law?
