Permission for temple work
I would like to do the work for my aunt and her husband is still alive. He is 95 and hard of hearing and lives in Germany. I have asked my cousin to ask her father for permission. They are all of catholic faith. He agreed, but now as I need his email address (he does not have an account) and phone number as well as his address my cousin was not happy with all this. She was concerned about data protection, and thought this was going too far. I thought it would be easier to go for the verbal agreement option, but now I am not sure they are ok with all this and they might change their minds. My cousin suggested to use her phone number as he will not be able to hear on the phone. Also, I am not sure she will be able to give me her email address for this purpose. Would it be sufficient to give her phone number only on the permission form, and she would answer a phone call related to the permission? Will she actually be called to confirm this? Need some advice here, please. Thank you.
