Simultaneous kiddush

Hi,

Ideally, two people should not recite kiddush simultaneously in the same space, if others are listening to their blessings and relying on them. It is hard for listeners to distinguish between the two voices. However, such a kiddush recitation would be valid; kiddush is beloved to the listeners, and so they listen carefully.

Have a great day,
