Q. Kvod Harav. Hoping you could speak to Rabbi Miller shlita regarding the policy of officiating at a wedding of irreligious people where non kosher food is served. When I spoke to Rabbi Miller about officiating at weddings of non religious (many years ago) he told me to have them sign that they resolve to get an Orthodox Ghett if the want to divorce. It’s what I do.
Please let me know if insistence on kosher is imperative to officiate as I certainly don’t want to do an issur.
Also to clarify if it’s a matter of issur or community policy.  Thank You,

Horav Shlomo Miller’s Shlit’a opinion is that one should avoid officiating at a wedding of irreligious people where non kosher food is served, even when some spiritual benefit is to be obtained.
