You can add FLS as an additional insured to your policy, presuming your management team allows you that authority, without FLS' permission, as you are the one paying for the policy. What cannot happen is FLS adding themselves as additional insured to your policy without your approval.
The key to the whole discussion is the phrase "Named Additional Insured". That phrase by itself, and without any other parameters limiting its use, conjures up all sorts of potential problems.
Here's one of ours;
- XXXXXXXX., is added as Additional Insured but only with respect to liability arising out of the operations of the Named Insured.
Additional Insured, or Additional Insured & Loss Payee, are quite common and are meant to cover both parties to the transaction at hand. In this case, I am covering X's liability, but only as it relates to my operations. The "& Loss Payee" part is used by finance companies like GE Cap, CIT, and the like. Never add a customer to the "& Loss Payee" part. Should you write of a truck, trailer, and cargo, you would need the customers authorization to cash the cheque for your truck and trailer. "Named Insured" in this case refers to me, the policy holder.
Named Additional Insured, without the "but ...", would mean I am insuring X for everything they do, whether it pertains to my operations or not.
Example ... a few years ago I was hired to make an oversize move within Norfolk County. Because I had to get a county permit, the county required an insurance certificate that included them as a Named Additional Insured. In effect I had to add Norfolk County to my policy which meant I covered all of their liabilities and potential liabilities for the effective time span of the certificate. So if on the other side of the county, a county truck caused an accident, my insurance would have to pay. It is immaterial that I had nothing to do with the county on that day.
Should such an event occur, the county's insurance would look at all the Named Additional Insured certificates that they had on hand and throw them before the court should a lawsuit occur. Our insurance would have no choice but to pay, and the county's own insurance would come last on the list of payees.
Needless to say, I informed the county that they could take a flying leap at a rolling doughnut, and didn't do the oversize move. My insurance company would not have endorsed it anyways.
Insurance is a very, very, very tricky business these days. Years ago you could count on your insurance policy to cover you for all perils. What you get now is an all perils policy with a list of exclusions a mile long. When you go over your policy with your broker, it should take 4 or 5 hours of reading and explaining to go through your policy. Your are being foolish, and not doing yourself any favours, if you are simply signing the policy as presented without knowing exactly what you are signing and paying for. If your broker has not set aside the whole day for you at policy renewal, find another broker.
