Contracts are essentially promises, or groups of promises, to do something in the future.If the promises have certain characteristics defined by law,then the promises give rise to rights which will be protected by society and the breach of the promises will give rise to enforced remedies.

合同实质上是对有关未来应完成事项的承诺或一系列承诺.如果这些承诺具有某些被法律确定的特征,那么这些承诺将产生权利,该权利受社会所保护,一旦违反将产生强制的补偿.
