An insurance endorsement is a document that changes, adds, or removes terms in an insurance policy.
Definition
An insurance endorsement is a document attached to or incorporated into a policy that changes its terms. It may add or restrict coverage, revise an exclusion, identify an additional insured, or alter another condition. The policy and its endorsements must be read together to understand the coverage arrangement. For a civil engineering firm, an endorsement may be requested to meet a client contract requirement or to reflect a project-specific arrangement. Its title alone does not establish the scope or effect, and an endorsement does not necessarily provide broader coverage than the underlying policy. Owners compare the actual wording with the contract request, including named parties, covered work, dates, limits, and exclusions. A certificate of insurance generally summarizes selected details but is not itself an endorsement. See ACEC for resources for engineering firms.
How owners use it
- Owners match each requested policy change to the corresponding endorsement wording and policy period.
- A firm files endorsements with the policy they modify so contract and certificate reviews use the same coverage record.
- If a client asks for three endorsements and the firm has received two, 3 - 2 = 1 requested document remains outstanding for follow-up.
- Owners review whether an endorsement names the right party and covers the relevant project or activity.
