Insurers are getting in the wedding business, offering some peace of mind for brides and grooms as the average cost of getting married climbs. Insurers are now covering cold feet. With the cost of the average American wedding reaching about $26,000, insurers have been selling a growing number of policies to protect against losses from extreme weather, illness and, in one firm's case, even a sudden change of heart.

The insurance is offered by a small number of U.S. companies. Insurers declined to provide data on the number of customers beyond saying they are growing steadily. It can cover losses from issues ranging from bankrupt wedding halls to cancelations forced by unexpected military deployments. Travelers says issues with vendors account for about a quarter of the claims, with most of those related to issues with photographers or videographers.
