House Bill No. 1688 amends various sections of the Oklahoma Statutes concerning vital records, particularly focusing on the registration and correction of birth and death certificates. The bill introduces a new definition for "minor correction," which encompasses errors such as misspellings or omissions, and requires applicants to provide clear evidence of such errors. It also clarifies the roles of the Commissioner of Health in the registration process and establishes procedures for filing these vital records, emphasizing the responsibilities of parents and medical professionals. Additionally, the bill mandates that death certificates be filed within three days of a death and limits the biological sex designation on birth certificates to male or female.

Further provisions include the replacement of the "State Registrar of Vital Statistics" with the "Department of Health," requiring funeral directors and physicians to register with this department to access the electronic filing system for death certificates. The bill mandates electronic filing of death certificates by specific deadlines for funeral directors and physicians and outlines their responsibilities regarding fetal death certificates. It also introduces a certificate of birth resulting from stillbirth, specifies conditions for amending birth certificates, and addresses the confidentiality of vital statistics records. The act is set to take effect on July 1, 2025, ensuring prompt implementation of its measures.
