A basic insurance policy that covers loss of photos, videos, attire, presents, rings and deposits usually costs anywhere between $155 and $550, depending on the amount of coverage you want. General liability insurance, which covers up to $1,000,000 for accidents, costs around $185.Rain, some say, can be good luck on your wedding day. But blizzards, sudden injury, or illness, can ruin the happy day. While you may not be able to prevent the unexpected, you can protect a portion of your investment by planning ahead. If you're thinking about buying wedding insurance—also called special event insurance—you should know that it has two parts. Cancellation or postponement coverage is one. If extreme weather forces cancellation, for example, this coverage will reimburse you for deposits or even the entire cost of a service or rental of a venue. It also can help pay for the costs incurred to reschedule the celebration.Whether your claim of extreme weather will be honored is a little less clear. If the wedding is canceled due to weather that has been deemed a state of emergency, the insurance will typically be honored. But if it is canceled due to a severe storm that is localized rather than statewide, the insurance company will have to make a decision. "The other part—liability coverage—indemnifies you if someone is injured during the wedding, or if there is property damage. You can buy either type of wedding insurance coverage, or both types. Before buying wedding insurance, check the coverage you already have. If you have homeowners or renters insurance, for example, these policies will reimburse you if wedding gifts are stolen or lost from your home or car. They also cover injuries to guests. Umbrella coverage, purchased on top of a homeowner policy, increases liability coverage for a small premium.If you plan on holding a wedding at home, consider buying or increasing your policy's umbrella coverage.
