Primary and Noncontributory Endorsement
A policy endorsement that designates a specific insurance policy as primary and prevents it from seeking contribution from other applicable insurance policies.
Definition
A primary and noncontributory endorsement is a contractual modification to an insurance policy, most commonly a general liability policy, that establishes the policy as the first source of coverage for a covered loss and eliminates the insurer’s right to seek contribution from other available insurance. This endorsement alters the standard “other insurance” clause by ensuring that the designated policy responds independently, without sharing financial responsibility with other policies that may otherwise apply to the same claim.
Structural Components
- Primary Coverage Designation: Establishes the policy as the first layer of response to a claim.
- Noncontributory Provision: Removes the insurer’s ability to request cost-sharing from other policies.
- Other Insurance Clause Modification: Overrides default policy language governing coordination between insurers.
- Endorsement Form Language: Typically implemented through specific forms or manuscript endorsements.
- Contractual Alignment: Often required by agreements such as master service agreements or construction contracts.
Parameters & Conditions
- Applies only when the endorsement is explicitly added to the policy.
- Typically required when one party agrees to assume primary insurance responsibility for another.
- Often used in conjunction with an additional-insured-endorsement.
- May be limited to specific contracts, projects, or operations.
- Subject to policy limits, exclusions, and coverage triggers.
