For a variety of reasons, many companies choose to incorporate in Delaware. But for all the benefits of doing so, one potentially unfortunate aspect is the state's vigorous enforcement of its unclaimed property laws. Unclaimed property laws require companies to report certain property (e.g., uncashed checks) with a lack of owner activity to the state after a specified period. When a company does not have the owner's last known address, it must report the unclaimed property to its state of incorporation, which for many companies is Delaware.
