TX Vital Records - The Texas Vital Statistics law to register births and deaths was not passed until 1903.Texas was then and is now a dual registration state which means the local registrars retain a copy of all birth and death records for the events that take place within their jurisdiction and the state retains the original of all birth and death records for the entire State of Texas.However, the statutes for registering these events were not made mandatory until 1926.However, many local registrars did not adhere to the statutes until the late 1930’s or early 1940’s.This means some records reside only in the local registrars’ files and not with the State.
