I have a number of death certificates for my female ancestors, and they don't mention any maiden name.
ADDED: These are all in England.
Headings: When and where died. Name and Surname. Sex. Age. Occupation. Cause of Death. Signature, description and residence of informer. When registered. Signature of Registrar.
Ah: just noticed that a 1970 death certificate has a space for "Maiden surname of woman who has married".

BUT not on a 1958 or 1961 certificate.
