Hamer v Sidway
(1881) 124 NY 538
Uncle promised nephew that, if he would refrain from drinking, using tobacco, swearing and playing cards or billiards for money until he was 21, he would pay him $5000. Nephew did this and claimed the $5000.
(1) There was no consideration given by the plaintiff and
(2) refraining from drinking etc were not a harm suffered but a benefit.
The Plaintiff had surrendered a legal right he had to drink etc and this was good consideration – even though it was beneficial to the Plaintiff.
