1. Elements of C.R.S. 18-15-104
For you to be convicted of criminal usury in Colorado, the state attorney general must prove beyond a reasonable doubt that you knowingly charged, took, or received any money or other property as a loan finance charge where the charge exceeded an annual percentage rate of 45%.1
This practice of lending money at unreasonably high rates of interest may also be known as:
- “loan-sharking” or
- “predatory lending.”
Note that it is also a Colorado crime to provide money or property to a person with the understanding that the funds may be used for engaging in usury.2 Even possessing or hiding records of criminally usurious transactions is a crime.3
2. Why Usury Happens
Some people struggle to qualify for a personal or small business loan due to:
- poor credit,
- no collateral, and/or
- a criminal history.
These people may have to take out a loan with unreasonably high-interest rates in order to get the money. Often the purpose of taking these loans is to:
- cover gambling losses,
- buy contraband,
- pay expensive medical bills, and/or
- pay bills to prevent losing their house or car.
Usury often involves loans provided by organized criminal syndicates.

There are several affirmative defenses to criminal usury.
3. Defenses
Here at Colorado Legal Defense Group, we have represented countless people charged with white-collar crimes such as usury. In our experience, if you have a signed written contract, your C.R.S. 18-15-104 charge should be dismissed if the court finds that either:
- At the time of making the loan finance charge, it could not have been determined that the annual percentage rate would exceed 45% a year; or
- The loan finance charge was not in excess of 45% a year when the rate of the finance charge was calculated on the unpaid balance of the debt on the assumption that the debt is to be paid according to its terms and is not paid before the end of the agreed term.4
Criminal usury charges should also be dropped in cases involving:
- reverse mortgages,
- credit card charges not exceeding those permitted, and
- other charges or fees permitted by Colorado law.5
4. Related Offenses
- Racketeering under the Colorado Organized Crime Act (C.R.S. 18-17-104) – A pattern of criminal activity generally committed by gangs or organized crime. This includes gambling, loan-sharking, fencing stolen property, or drug distribution.
- Money laundering (C.R.S. 18-5-309) – Moving money around to try to evade the government’s ability to track the source of the funds. Money laundering may be used to hide money that was embezzled from an employer.
- Extortion (C.R.S. 18-3-207) – Threatening someone in order to get that person or another to do something or refrain from doing something against their will. Extortion is commonly called “blackmail.”
- Bribery (C.R.S. 18-3-302) – Offering money or other benefits to a public official to influence their actions.

Not all high-interest loan agreements are usurious under C.R.S. 18-15-104.
