Middlesex County Death Index
The Middlesex County Death Index covers death records for Massachusetts's most populous county, home to over 1.6 million residents across dozens of cities and towns. This guide explains where to find Middlesex County death records, how to search them online, and which offices to contact when you need certified copies or supporting documents for estates, genealogy research, or legal purposes.
Middlesex County Overview
How Death Records Work in Middlesex County
Massachusetts does not maintain death records at the county level. That surprises many people who start their search at a county courthouse. In Middlesex County, death certificates are filed with the city or town clerk where the death occurred. The state then collects those records through the Registry of Vital Records and Statistics, which is part of the Massachusetts Department of Public Health.
The Registry of Vital Records and Statistics (RVRS) holds statewide death records from 1926 to the present. For deaths that happened before 1926, you need to contact the Massachusetts State Archives, which holds records going back to 1841. Massachusetts was the first state in the country to require statewide death registration, starting in 1841 - so Middlesex County towns have long, detailed records compared to most other parts of the country.
Records before 1841 are held only by individual town clerks. Those very old records exist in some towns, but they are not part of any statewide index. For genealogy work going back before 1841, you may need to contact each town separately or use published transcriptions.
Note: The RVRS is located at 150 Mount Vernon Street in Dorchester, and death record requests can also be submitted by mail or through VitalChek online.
Middlesex County Probate and Family Court
The Middlesex Probate and Family Court handles estate matters for residents who die in the county. Probate files are often a key resource when death certificates are hard to find or when you need more detail about a person's life and family. The court has three locations serving different parts of the county.
The Cambridge courthouse is at 208 Cambridge Street, Cambridge, MA 02141, and can be reached at (617) 768-8500. The Lowell location is at 41 Hurd Street, Lowell, MA 01852, phone (978) 459-2801. A third location in Woburn handles cases at 200 Trade Center, Woburn, MA 01801, phone (781) 939-2700. Full information is available on the Middlesex Probate and Family Court page.
Probate records can help fill gaps in your research. If a death certificate is missing or damaged, an estate file may contain the date of death, the names of heirs, and sometimes even a cause of death noted in medical affidavits. Middlesex County has probate records indexed from 1643, making it one of the oldest probate archives in the United States. Estate inventories, guardianship papers, and name change records are all searchable through the court.
Under MGL Chapter 46, death records become part of the public record once filed with the state. Probate records work alongside vital records to give a more complete picture of someone's death and the legal steps that followed.

Middlesex County Registry of Deeds
The Middlesex Registry of Deeds has two districts. The Northern District serves cities and towns in the Lowell area, located at 360 Gorham Street, Lowell, MA 01851, phone (978) 322-2030. The Southern District, which covers Cambridge, Somerville, and nearby communities, is at 208 Cambridge Street, Cambridge, MA 02141, phone (617) 679-2030. Both are open Monday through Friday, 8:30 AM to 4:30 PM. More information is available at the Middlesex Registry of Deeds page.
Deed records become relevant after a death when property must transfer to heirs or be sold to settle an estate. When you search deed records around the time of a death, you can often find the date of transfer, the names of surviving family members, and the administrator or executor of an estate. These details can confirm dates and relationships that are useful for genealogy work. The registry does not hold death certificates, but it can point you toward the right family members and timelines.

Note: The southern district serves most of the populous cities in Middlesex County, including Cambridge, Somerville, Malden, Medford, and Waltham.
Searching Death Records in Middlesex County
The best free starting point for Middlesex County death records is FamilySearch Massachusetts Vital Records. FamilySearch has digitized a large portion of Massachusetts vital records, including many Middlesex County towns. You can search by name, year range, and town at no cost. The State Archives digital images for deaths from 1841 to 1924 are also free online, and the site includes the old "Tan Books" that transcribed records up through 1850.
Ancestry.com holds records beyond what FamilySearch offers, particularly for the later years. A subscription gives access to indexed death records, and the indexes can often link to original images. For deaths from 1926 forward, the RVRS is the main source. You can order through the state's official ordering page at mass.gov. In-person orders at the RVRS at 150 Mount Vernon Street in Dorchester cost $20 per copy. Mail requests are $32. Online through VitalChek costs $54 for the first copy.
The State Archives vital records collection covers 1841 through 1925 at a cost of $3 per certified copy. If you only need to confirm that a record exists, the free digital images may be enough. Middlesex County has extensive coverage in the State Archives because the county was one of the most populated parts of Massachusetts throughout that entire period.
What Middlesex County Death Certificates Contain
A standard Massachusetts death certificate includes the full name of the deceased, date of death, place of death, date of birth, age, occupation, parents' names, spouse's name, cause of death, and the name of the attending physician or certifier. The place of burial is also listed. These fields have been standard since the mid-1800s, though older records may have fewer details than modern ones.
MGL Chapter 46 Section 12 governs what information must appear on a death certificate in Massachusetts. Section 13 sets out rules for amendments to death records. Both sections apply statewide, so Middlesex County death certificates follow the same format as certificates from any other county. The level of detail on older records can vary a lot. A certificate from 1850 may list only a name, date, and cause of death. A modern certificate includes far more identifying information.
Death certificates also show the informant, meaning the person who provided the information at the time of death. That is often a spouse, child, or other close relative. The informant's name can be a useful lead for genealogy research if you are trying to identify surviving family members.
Getting a Middlesex County Death Certificate
You do not order a death certificate from Middlesex County directly. Massachusetts processes death certificate requests through the RVRS for records from 1926 forward. The RVRS is at 150 Mount Vernon Street, Dorchester, MA 02125, phone 617-740-2600, email vital.recordsrequest@mass.gov. Hours are Monday through Friday, 8:45 AM to 4:45 PM.
For older Middlesex County records, the State Archives at 220 Morrissey Boulevard in Boston handles requests. Phone is 617-727-2816. Copies are $3 each. Free digital images are available on the Archives website for deaths from 1841 to 1924. If you need a record from before 1841, your best option is to contact the town clerk in the specific Middlesex County town where the death occurred.
MGL Chapter 46 Section 9 makes Massachusetts death certificates public records. Anyone can request a copy. You do not need to prove a family relationship to access a death certificate, though some very recent records may have additional restrictions. The public nature of these records is one of the reasons Massachusetts vital records are so well-studied for genealogy purposes.
Note: If you are unsure whether to contact RVRS or the State Archives, the cutoff year is 1926 - records from 1926 and later go to RVRS, and earlier records go to the State Archives.
