Something similar happened to me and my husband, sent of life assurance application form, husband had serious accident, forgot (stress of hospitilisation etc ) about life policy which arrived soon after accident and then a couple of months later wrote to the life insurance company explaining the accident, they looked into it - medical reports etc - and decided nothing needed to be done. For sure you should tell the insurance company what has happened. Then at least you know where you will stand before taking any decisions. Hope everything goes ok for you both healthwise in the future.
