Contract law treats responsibilities set up by accord (express or implied) between individual parties. Broadly speaking, contract law in dealings necessitating the sales event of trade goods has become extremely standardised across the country as a consequence of the far-flung acceptance of the Uniform Commercial Code. However, there's still important variety in the interpreting of other forms of contracts, depending on the extent to which a certain state has written its case law of contracts or acquired portions of the Restatement (Second) of Contracts.

Parties are allowed to accord to intermediate conflicts originating from their agreements. Under the Federal Arbitration Act (which has been translated to address all agreements going up under federal or state law), arbitrament articles are broadly speaking enforceable unless the party rejecting arbitrement can display unconscionability or dupery or something else which weakens the whole contract.
