Another area that is ripe for litigation is breach of warranty law. Warranties commonly come with almost every single, consumer product that is sold. However these warranties are usually contained in small booklets all writing. Nonetheless for significant consumer purchases you should read the entire warranty. As an example on an expensive TV, receiver, stereo component or computer you should read the warranty to determine your rights if there is an issue. Also an arbitration agreement by be included.
It is imperative that you follow the terms and conditions of the warranty. Many times there is a specific person must be notified in writing by regular and certified mail. First you need to follow the terms, then you need to document your communication, then you needed to document the response from the manufacturer or supplier.
Ultimately, when, and if you have to make a litigation claim against them you will have all of your ducks in a row.
