I know that some mitzvas have particularities about who can be yotzei, from whom, and under what circumstances. For example, for kiddush, one is required either to make it or hear it made by one who obligated in kiddush.
Is havdalah the same? Must one hear havdalah made by one who is obligated in havdalah?
--Or do the blessings literally just need to be heard in some form?
