Many commercial insurance policies will include a state-specific endorsement that alters your contract's conditions so that it fits the guidelines and the laws of the state where the policy is based.
Usually, this will relate to renewal, cancellation, and the non-renewal process. Also, outlining how the administrative tasks are to be handled.
It is important to be clear here that these endorsements aren't adding or even removing coverage but instead further detailing the duties and processes required by your business in the state of its incorporation.
