If you need the background, you can read my other question. But I'm interested in answers to this one independently of the situation described there.
I allowed somebody to perform "Lastschrift" (take money from my account) regularly. If I kept a copy of the form I signed, I cannot find it. But I know that these permissions ("SEPA Mandat") have an expiry date.
Is there a way for me to find out when is the expiry date of the permission I signed? Will my bank know it, or the other person's bank, or some regulation institution?
