What is a bail bond in Mexico?

In Mexico, a surety bond is a legal guarantee issued by a surety company, authorized by the National Insurance and Surety Commission (CNSF), to support the fulfillment of a contractual, fiscal, or judicial obligation.

The most common bonds in public works are:

• Performance bond : guarantees that the construction company will complete the project according to the contract.

• Advance bond : guarantees the correct use of advances delivered by the government or client.

• Hidden defect guarantee : covers defects not visible during delivery of the work.

• Bid Bond (Tender) : Ensures that the bidder will uphold its offer if awarded.

• 
  

These bonds are regulated by the Federal Law on Surety Institutions and are of an accessory nature: they do not exist in isolation, but are linked to a primary obligation.

What is a bond in the US?

In the United States, so-called surety bonds are used, and the two main ones in the construction sector are:

• Performance Bond : Guarantees that the contractor will fulfill the contract.

• Payment Bond : guarantees payment to suppliers, subcontractors and workers involved in the project.

  
  

These bonds are required by the Miller Act (and its state counterparts) for federal public works projects. Unlike in Mexico, these instruments are not issued by surety bond companies, but by commercial insurance companies under surety agreements, although they essentially serve a similar function.

Key differences between Mexican surety bonds and US bonds (Mexican surety bonds vs US bonds: key differences every business should know)

Feature	Surety Bonds (Mexico)	Bonds (USA)
Issuing entity	Surety bonds regulated by CNSF	Insurance companies
Legal framework	Federal Law on Surety Institutions	Miller Act/Uniform Commercial Code
Instrument	Accessory contract	Self-employed contract
Claim	Requires a sentence or formal procedure	It can be executed with simple notice
Refundability	The guarantor must reimburse the surety company	The contractor reimburses the surety
Common scope	Contracts with government and private companies	Mainly federal and state public works

What implications does this have for your company?

If you're entering into a contract in Mexico, you'll most likely be required to have a surety bond regulated by a Mexican bonding company. If you're expanding to the U.S., you should work with an insurance company that issues bonds and have a broker familiar with the local rules.

But beyond the technical aspects, there is a fundamental difference:

• In the US, bonds are viewed as part of a project's overall financial management.

• In Mexico, they are often still perceived as "just another requirement," which can work against you if you don't take advantage of it strategically.
