Do I need to submit my old passport when applying for a new one?

When applying for a new passport with HM Passport Office, it is generally required to submit your old passport as part of the application process. This helps to verify your identity and proves your citizenship. HM Passport Office may need to retain the old passport for its records, and it will typically be returned to you after the new passport is issued. If your old passport is lost or damaged, different requirements may apply, and you should provide any available documentation to support your application. It is always a good idea to check the latest guidelines on the official HM Passport Office website for detailed information and to ensure you have all the necessary documents ready for your application.
