Register office (United Kingdom)
A register office, commonly referred to unofficially as a registry office or registrar's office is an office in the United Kingdom, Republic of Ireland and some Commonwealth countries responsible for the civil registration of births, deaths, marriages, civil partnerships, stillbirths and adoptions.
Historically local register offices were organised under a General Register Office, with a registrar-general responsible for their administration. A network of local offices provided a public-facing function and were responsible for registrations within their respective areas.
In addition to their role in registration, register offices in the United Kingdom conduct civil marriage and civil partnership ceremonies, as well as other civic ceremonies.
