Every day we form a contract for the provision of things or services. When you drive into a parking lot you create a contract with the proprietor to use part of his land to park your car. This is a contract and if your car is not there when you return you want to hold him accountable. Can you? We exchange a promise for something to be supplied or done and form a contract and the law on the subject is very involved because society has been using contracts for centuries.

Contracts include the sale and purchase of land, leases of land, buying and selling businesses.
