To complete Form CG 24 04, the ISO Waiver of Transfer of Rights of Recovery Against Others to Us endorsement, you fill in the schedule with the full legal name of the person or organization receiving the waiver and, if the form provides the field, a description of the operations or locations the waiver covers. The form itself is short because ISO pre-prints the operative language; your job is accurate schedule data pulled from the underlying contract, submitted through your broker before any loss occurs.
What You Are Actually Signing Up For
Every standard Commercial General Liability policy includes a condition called “Transfer of Rights of Recovery Against Others to Us.” That condition requires you to hand your insurer the right to pursue whoever caused a covered loss, so the insurer can seek reimbursement after paying your claim. The legal concept is subrogation: once the insurer pays, it steps into your shoes against the responsible party.1Cornell Law Institute. Subrogation
Attaching the CG 24 04 overrides that condition for the party you name in the schedule. Your insurer gives up any right of recovery it would otherwise have against that party for payments made because of injury or damage arising from your covered operations.2International Risk Management Institute. Subrogation and the CGL Policy That is why contractors, landlords, and vendors ask for it: they want assurance your carrier will not sue them after a covered event.
Filling In the Schedule
The schedule has two fields that matter.
Name of Person or Organization
Enter the full legal name of the party receiving the waiver, and make it match the entity name in the underlying contract exactly. If the service agreement is with “Meridian Construction LLC,” do not shorten it to “Meridian Construction” or “Meridian.” A mismatch can give your insurer grounds to argue the waiver does not apply to the party you intended to protect.
Pull the name directly from the insurance requirements section of the contract that triggered the request. Do not rely on how the party signs emails or how their name appears on their website.
Description of Operations or Locations
Some versions of the form include a field to narrow the waiver to specific job sites, projects, or types of work. If your contract limits the waiver to a particular project, put that description here. Leaving the field blank or writing something too broad can create ambiguity later about what the waiver actually covers.
If the schedule information is not printed on the endorsement itself, the form states it will appear in the policy declarations instead. Your broker handles the data entry into the carrier’s system, but the accuracy of the entity name and project language is on you.
Blanket Schedule Wording
Some policies use blanket wording in place of a specific name. A common entry reads: “Person(s) or Organization(s) as required by written contract when such written contract is executed prior to an occurrence, offense or loss to which this endorsement applies.” That language automatically extends the waiver to anyone you have contractually agreed to protect, without needing a separate endorsement for each one.
Blanket wording is more common on the CG 24 01 form, but some carriers will write it into the CG 24 04 schedule as well. If your business regularly signs contracts requiring waivers of subrogation, ask your broker whether blanket language is available on your policy. It prevents gaps when you forget to request a scheduled endorsement for a new contract.
Submitting the Request
Once you know the entity name, any location or project restriction, and the effective date the waiver needs to be in place, send those details to your insurance agent or broker. The broker submits the request to the carrier’s underwriting team. After approval, the underwriter issues the endorsement as an addition to your existing CGL policy. You receive either a standalone copy of the CG 24 04 form or an updated policy declaration reflecting the change, and that document is what you provide to the party that required the waiver.
Expect an additional premium. For general liability, the charge typically falls between $50 and $150 per endorsement, though some carriers charge up to $250 depending on perceived risk and policy terms. Most carriers process the request within a few business days. If your contract has a hard deadline, give your broker at least a week of lead time.
Get It Issued Before the Loss
The endorsement contains a built-in timing requirement. Its own language limits the waiver to persons or organizations “as required by written contract when such written contract is executed prior to an occurrence, offense or loss to which this endorsement applies.” A separate clause reinforces this by stating the waiver applies “only to the extent that the insured has waived its right of recovery against such person(s) or organization(s) prior to loss.”
You cannot add the endorsement retroactively after an incident and expect it to shield the other party. If a fire destroys a job site on Tuesday and you request the waiver on Wednesday, it will not apply to that loss. The contract requiring the waiver and the endorsement itself both need to be in place before anything goes wrong. Most compliance failures happen in exactly this gap: a subcontractor begins work before the endorsement is issued, an accident occurs, and the waiver does not apply.
What the Endorsement Does Not Do
The CG 24 04 does not expand your policy. It does not raise your limits, broaden your covered operations, or change what counts as an occurrence under the CGL form. A $1,000,000 per-occurrence limit stays a $1,000,000 limit. The waiver simply removes the insurer’s right to recover from the scheduled party after paying a covered claim.
It is also specific to the CGL policy it is attached to. It has no effect on workers’ compensation, commercial auto, professional liability, or any other coverage line. If a contract requires waivers of subrogation across multiple coverage types, you need separate endorsements on each policy. Workers’ compensation waivers in particular use a different form.
The endorsement waives only your insurer’s recovery rights, not your own. If you have a personal claim against the scheduled party that falls outside what your insurer paid, the endorsement does not affect your ability to pursue it.2International Risk Management Institute. Subrogation and the CGL Policy And the waiver does not create “primary and noncontributory” coverage for an additional insured; that takes separate endorsement language.
Waiver vs. Additional Insured Status
Contracts often require both, and the two are not interchangeable. Additional insured status gives the other party direct access to your CGL policy so they can tender a claim and get a defense. A waiver of subrogation prevents your insurer from pursuing the other party to recover what it paid. Insurers have successfully subrogated against additional insureds in several situations, including losses outside the scope of the additional insured endorsement, losses exceeding policy limits, and situations where the additional insured is not covered on umbrella or excess layers.3International Risk Management Institute. Additional Insured Status and Waivers of Subrogation The CG 24 04 closes those gaps for the named party.
State Enforceability
Waivers of subrogation are generally enforceable because courts treat them as risk-allocation tools rather than exculpatory clauses. The main legal risk comes from state anti-indemnity statutes, particularly in construction. Forty-five states have enacted laws that limit or prohibit certain indemnification agreements in construction settings, and a handful go further by voiding waivers of subrogation in specific contexts. Kansas nullifies contract clauses that waive subrogation rights for losses covered by liability or workers’ compensation insurance. Louisiana and New Mexico expressly prohibit waivers of subrogation in oil and gas or construction contracts under their respective oilfield anti-indemnity acts.
Scope varies. Some statutes apply only to public construction projects; others cover all construction contracts. Some target only broad form indemnity provisions, leaving more limited agreements intact. Before relying on a CG 24 04 in a construction contract, check whether the state where the project is located has an anti-indemnity statute that reaches waivers of subrogation. Your broker or an attorney familiar with that state’s construction law can confirm.
