There has been increasing fraud in real estate and signing up for a notification service where deeds and other property documents are kept may help prevent fraudulent conveyances, or at least give you notice when it happens. You may receive a mailing appearing to be from the Commonwealth of Massachusetts or other source which offers this service for an annual fee. For folks in Massachusetts: Why pay when you can get an official notification from the source for free - you should consider signing up for the official, free service to monitor filings at the Registry of Deeds for residential property owners. It's called the Registry of Deeds Consumer Notification Service and is found here: https://cns.masslandrecords.com
For folks in Texas, you can sign up for a Fraud Alert at the County Clerks website for your county.
