ACORD 25
The ACORD 25 is the standard US Certificate of Liability Insurance. It summarizes policies in force — it does not confer rights by itself.
CG 20 10
ISO form that names another party as additional insured while work is ongoing.
CG 20 37
The completed-operations companion to CG 20 10. Many construction and roofing claims arrive after substantial completion.
CG 24 04
The vendor’s GL insurer waives its right to recover from you after paying a claim.
Additional insured
Being named as certificate holder is not the same as being an additional insured.
Waiver of subrogation
Stops the vendor’s insurer from suing you after it pays a loss that may involve your alleged negligence.
Primary and non-contributory
The vendor’s policy pays first and cannot seek contribution from yours.
