You would typically prove that with some sort of birth certificate or a similar document stating that you have the same parent(s), i.e. that your father and/or your mother have the same name, date and place of birth. Obviously, you would have to provide a birth certificate for the sponsor and another one for the applicant. In some countries, it’s also possible to submit a copy of a family register that would document your relationship even more directly.
