What is the name for policy endorsements that may apply to more than one coverage part?

• A. Interline Endorsements
• B. Endorsements by Section
• C. Monoline Endorsements
• D. Supplemental Endorsements

Answer: (A)

Interline endorsements are endorsements designed to affect more than one coverage part within a policy. They streamline coverage changes that should apply across multiple lines (for example, property and liability under a commercial package policy) by using a single endorsement rather than duplicating language in each part. This helps ensure consistent terms across parts and simplifies endorsements like waivers of subrogation or additional insured provisions that should apply to multiple coverages.

Monoline endorsements, in contrast, affect only one line of coverage, not multiple parts. Endorsements by section isn’t a standard term for cross‑line endorsements, and supplemental endorsements refer to extra coverages added but not specifically defined as cross‑line endorsements.
