With the old surname.
Because only after making affidiavit, he gets the new surname.
Generally, when you give public notice for name change, it will be pulished under old name and only after publication you get new name.
When name is changed through government gazette notification, in the relevant affidiavit you are required to sign your old name, as per rule.
