Say Matt has been sentenced to perform 10 hours of community service by a judge. His dad encourages him to be a good boy by offering him $1000 if he completes the hours. Matt accepts the offer. There is a text message record of this exchange. After Matt completes his community service, his dad reneges and doesn't give him the $1000.
Does Matt have a valid claim that he has a contract with his dad? Or does the community service not constitute sufficient consideration for a contract?
