If you experience a breach of contract from your wedding venue, reread your contract to find out if the reasoning they provided was one of the acceptable reasons stated. Depending on what's outlined in your agreement, you may be able to negotiate a new location at the venue, a different date, or the return of your deposit. However, if the venue breaches the signed contract and the force majeure clause doesn't apply, there's no guarantee the venue will allow you to reschedule your event. You might lose the money you've paid if you don't have cancellation insurance, and you'll need to find a new venue.
