1922-present: In 1922, the county Probate & Family Courts were granted concurrent jurisdiction over divorces. Some Superior Courts gradually stopped hearing divorces and/or moved their current divorce records to the Probate & Family Court, while other counties continued hearing divorces in either court up until the 1980s. Divorces heard through probate are maintained by the Probate & Family Courts in each county. You may contact the courthouse directly to inquire about divorces from this period. Additionally, an index for cases since 1952 is available at the Department of Public Health, Registry of Vital Records and Statistics. Researchers may contact the Registry of Vital Records at (617) 740-2600, or through the Registry of Vital Records and Statistics online. Please note that the Registry of Vital Records and Statistics does not hold divorce records. They can only provide you with the court that granted the divorce and the docket number.
Thus...I suggest you try locating the record in the index held by the Registry of Vital Records and Statistics. And then contact the appropriate county court to locate the records. Hope this helps.
