Some Insurers won't arrange cover for people who have been bankrupt and some will.
Suggest that you contact a local broker. Or try Direct Line or Home Protect. Direct Line don't appear to mention bankruptcy in their assumptions for quoting. Have a look to see whether they ask about this. Home Protect can arrange Insurance in most circumstances.
Because the mortgage is in your husbands name, it may be thought that you don't hold any financial interest. Therefore some won't arrange in your name. But your husband should be able to arrange a policy.
