The Municipal Archives of New York City offers a searchable inventory spreadsheet to locate marriage contracts from the years 1901-1967.
The majority date from 1902-1907 (date of marriage contract). Though there are marriage contracts for people from all five boroughs of New York City, the contracts are arranged by a sequential number assigned by the City Clerk’s Office, numbers 1 to 8616. Most contracts were filed within a few days of the marriage but the 8600 numbered contracts were filed a few months or sometimes years after the marriage. Marriage contracts before 1908 pre-date the marriage license requirement.
Information on the contracts include the name and address of the persons getting married; names and residences of the witnesses; name of the notary public; signatures of all involved, plus the date the contract was received by the City Clerk. Sometimes the place of birth of the bride and groom is also listed.
