How does stating Primary and Non-Contributory effect your general liability insurance?

Primary and Non-Contributory Wording means your General Liability policy, or any insurance policy that has this endorsement on it, will pay first in the event of a claim. The Non-Contributory part means that not only will your policy pay first, but it will pay the full amount of the claim until the limits are exhausted without your client contributing to the loss with their own insurance. Not all General Liability policies have this coverage built in and it can be quite expensive to purchase if your policy was issued without it.
