In the large majority of cases your real property is recorded land. Your evidence of title will be a quitclaim deed.
If your property is registered land, you may have received a large document called an Owner's Duplicate Certificate of Title. Owners' Duplicate Certificates of Title were eliminated as of April 9, 1997. After this date, you would have received a certified copy of your Certificate of Title. (If you are not sure whether your real property is recorded or registered, call your Registry of Deeds.)
Chapter 218 of the Acts of 2004 guarantees this act shall apply to declarations of homestead recorded or filed for registration pursuant to section 1 or 1A of chapter 188 of the General Laws before, on, or after the effective date of this act, but the increase in the amount of homestead protection for declarations recorded or filed for registration before the effective date of this act shall not have priority over, and shall be subordinate to, any lien, right or interest recorded or filed for registration before the effective date of this act.
