What is the difference between self "bonded" and person "insured"?
Answers: Being insured, means an insurance company has issued a "policy" protecting you against faultless things happening. Generally, it includes coverage againt a lawsuit brought by ANYONE.
Being bonded, means an insurance company have offered a guarantee, to a specific third party and only that specified third deputation, that you will or will not do something, and if you fail to do what you're supposed to do, the insurance company pays them a pre-set amount.
I've explained it here before several times - just do a search for surrounded by YA for BOND.
