Ask in person to be taken off the town hall register when you leave Spain, and phone first to check opening days.
Bring the completed generic written application and your original, valid identity document. State that you are requesting padrón deregistration because you are leaving Spain. Ask the registry about any additional evidence for your circumstances and retain proof of submission; handing in the request is not itself confirmation of completion.
