When your mortgage is paid off you must discharge the mortgage in order to clear your property’s title. This done by recording a document at the Registry of Deeds usually called either a “Discharge of Mortgage” or a “Satisfaction of Mortgage”.
Sometimes, your lending institution or closing attorney will file the discharge on your behalf, but more often you will receive the Discharge of Mortgage in the mail and will need to file it yourself.
In order to make public notification that you have paid your mortgage off, you need to bring the “original” Discharge of Mortgage provided by the bank to the Registry of Deeds along with either cash or a check in the amount of $105.00. The Registry will record the Discharge and return it to you immediately.
