"It is estimated that one person in every ten has abandoned property. According to the Massachusetts Abandoned Property Laws, most financial assets that have been inactive for more than three years are declared “abandoned” and turned over to the Commonwealth.
Many citizens have questions about abandoned property, such as why do states have abandoned property laws and how do I file a claim for my property? With this web site we seek to answer many of your questions and reunite abandoned assets with its rightful owners." (taken from Massachusetts State Treasury Abandoned Property Division Website)
