## What Are Surety Bonds?

A surety bond guarantees that your business meets a specific obligation to a customer, contracting party or government agency. If a contract, license or permit requires one, get its exact form and amount; a bond is not insurance for your own losses. [10](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [11](https://www.sba.gov/funding-programs/surety-bonds "Surety bonds") [12](https://www.law.cornell.edu/uscode/text/40/3131 "40 U.S. Code § 3131 — Bonds of contractors of public buildings or works") [13](https://www.chubb.com/us-en/surety.html "Surety Bonds") [14](https://www.harperinsure.com/coverages/surety-bonds "Surety Bonds Insurance")

## What Are the Key Differences Between Marsh McLennan Agency and WTW Surety Bonds?

### Scope and Geographic Reach

WTW’s FY2024 annual report describes its Global Surety team placing bonds across industries and around the world. Marsh McLennan Agency’s overview specifically identifies contract surety and commercial license-and-permit bonds and describes organizations of varying sizes. The WTW statement is broader on geographic and industry reach; the MMA page gives more detail about its named bond categories. If your obligation crosses borders, ask WTW which local surety entity and form applies; for a domestic construction or licensing requirement, confirm the exact MMA program and market. [3](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk | MMA") [8](https://www.sec.gov/Archives/edgar/data/1140536/000095017025026278/wtw-20241231.htm "WTW 2024 Form 10-K")

### Binding Confirmation and Document Review

WTW’s North American terms say an insurer’s quote is not confirmation of coverage: after the client orders binding, WTW seeks a formal insurer commitment, typically a binder, and reviews the issued policy documents against negotiated terms. MMA describes adviser-led placement but its overview does not explain those steps. Buyers need written evidence that the bond is bound and that its obligee, amount, and conditions match the requirement. Ask MMA who confirms the surety’s commitment and checks the final bond wording. [3](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk | MMA") [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)")

## What Should You Confirm in Marsh McLennan Agency and WTW Surety Bonds Quotes?

- Will WTW’s Global Surety practice place this bond in the required jurisdiction, and who confirms the binder and final form? [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)")
- How will MMA confirm binding and verify the issued bond matches the obligee’s requirement? [3](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk | MMA")
