Yes, I have liability insurance and most venues will require that your DJ has at least a $1mil liability policy. Liability insurance protects the venue in case of unforeseen equipment falling and causing harm as well as provides medical compensation to the person in need. It’s a very rare circumstance that it would ever need to be used but it’s very important to be sure your DJ has a policy before booking them. If a client doesn’t find out until the wedding day that the venue requires it and they’ve hired a wedding DJ without insurance it could mean the DJ won’t be able to setup and perform for the wedding.
