Under CRS 18-5-102, Colorado law defines the crime of forgery as making, completing, altering or uttering (offering up) falsified documents with an intent to defraud. The offense may be filed as a misdemeanor or a felony depending on the circumstances.
Examples of forged documents include:
- A fake will;
- An unemployment insurance application with a false Social Security number;1
- A made-up letter of recommendation for a job;2
- A false tax return;3 or
- Doctored university transcripts
Colorado also punishes possessing forged instruments or devices capable of producing one.
Penalties
The punishments for forgery depend on the type of document. It is a class 5 felony to falsify cash, stock certificates, or legal documents. Under CRS 18-5-102, this carries:
- 1 to 3 years in Colorado State Prison, and/or
- A fine of $1,000 to $100,000
Meanwhile, forging most other types of documents is a class 2 misdemeanor. This carries:
- Up to 120 days in jail, and/or
- A fine of up to $750
Possessing a falsified document can be a felony or a misdemeanor. It depends on the document. But it is always a class 6 felony to possess a device that makes forged instruments. This carries:
- 1 to 1 ½ years in prison, and/or
- A fine of $1,000 to $100,000
Defenses
Three potential forgery defenses are:
- The defendant had no intent to defraud;
- The document was authentic; or
- The police committed misconduct

1. What is Colorado’s legal definition of forgery?
Forgery is making a fake document or falsifying an existing one with the intent to defraud someone with it. As discussed below, Colorado has six separate forgery crimes.
Documents need not be completely false for a person to be guilty of forgery. Merely inserting one untrue piece of information qualifies.4
It is also unnecessary that the person receiving the fake document fall for the fraud. All a forgery conviction requires is that a defendant has the intent to defraud.5
18-5-102 CRS states that:
(1) A person commits forgery, if, with intent to defraud, such person falsely makes, completes, alters, or utters a written instrument which is or purports to be, or which is calculated to become or to represent if completed:
(a) Part of an issue of money, stamps, securities, or other valuable instruments issued by a government or government agency; or
(b) Part of an issue of stock, bonds, or other instruments representing interests in or claims against a corporate or other organization or its property; or
(c) A deed, will, codicil, contract, assignment, commercial instrument, promissory note, check, or other instrument which does or may evidence, create, transfer, terminate, or otherwise affect a legal right, interest, obligation, or status; or
(d) A public record or an instrument filed or required by law to be filed or legally fileable in or with a public office or public servant; or
(e) A written instrument officially issued or created by a public office, public servant, or government agency; or
(f) Part of an issue of tokens, transfers, certificates, or other articles manufactured and designed for use in transportation fees upon public conveyances, or as symbols of value usable in place of money for the purchase of property or services available to the public for compensation; or
(g) Part of an issue of lottery tickets or shares designed for use in the lottery held pursuant to part 2 of article 35 of title 24, C.R.S.; or
(h) A document-making implement that may be used or is used in the production of a false identification document or in the production of another document-making implement to produce false identification documents.
(2) Forgery is a class 5 felony.
(3) Uttering a forged document to a peace officer shall create a presumption that the person intended to defraud such peace officer.
1.1. Forgery – CRS 18-5-102
First-degree forgery under CRS 18-5-102 occurs when someone with fraudulent intent fakes or falsifies any of the following documents or devices:
- Government-issued money, stamps, securities, or other valuable instruments;
- Part of an issue of stock, bonds, or other instruments. And they represent interests in — or claims against — a corporation or other organization or its property;
- A deed, will, codicil, contract, assignment, commercial instrument, promissory note, check, or other instrument. And it affects a legal right, interest, obligation, or status;
- A public record or an instrument that is legally fileable with a public office or public servant;
- A government-issued official written instrument;
- Tokens, transfers, certificates, or other articles. And they are for public transportation, property, or services.
- Lottery tickets or shares under CRS 14-35-2; or
- A document-making implement. And it may be used to falsify or make false documents.
Colorado prosecutors normally have the burden to prove defendants have an intent to defraud. But when the case involves presenting forged documents to a peace officer, the court may presume the defendant has fraudulent intent. And the defendant has the burden to prove otherwise.
1.2. Second-degree forgery
Forging any instrument not mentioned in the previous subsection is second-degree forgery under CRS 18-5-104 if the defendant:
- Knows that an instrument is forged, and
- Intends to defraud someone with it
Examples of second-degree forged instruments include:
- Altered letters of recommendation,
- Forged signatures on credit card charge slips,
- Insurance applications with false information
1.3. Use of forged academic record
CRS 18-4-104.5 prohibits people from making or altering an academic record if they intend to either:
- Seek a job with or admission to a public or private college in Colorado; or
- Apply for a scholarship or financial aid
“Academic record” can mean a:
- Transcript,
- Diploma,
- Grade report, or
- Similar document of an institution of secondary or higher education
Example: Penny lives in Denver and failed English her junior year of high school. When applying to college at Colorado State, she doctors the F on her transcript to look like an A. But before mailing out her application, Penny has a change of heart. She tears up her fake transcript and uses the real one. Had Penny sent out the fake transcript, she could have faced forgery charges. But since she stopped short of using the falsified transcript, she escaped criminal liability.
1.4. Criminal possession of a forged instrument
Having any forged instrument prohibited by CRS 18-5-102 is a crime under CRS 18-5-105 when the defendant both:
- Know that the instrument is forged, and
- Has the intent to defraud someone with it
Forgery under CRS 18-5-102 is discussed above in section 1.1. And as discussed below in section 2, possessing a forged instrument is a less serious crime than trying to use it.
1.5. Criminal possession of a second-degree forged instrument
Possessing a second-degree forged instrument is a Colorado crime under CRS 18-5-107 when the defendant both:
- Know that the instrument is forged, and
- Has the intent to defraud someone with it
Second-degree forgery is discussed above in section 1.2. And as discussed below in section 2, possessing a forged instrument is a less serious crime than trying to use it.
1.6. Criminal possession of forgery devices
CRS 18-5-109 prohibits making or having counterfeiting devices. Examples are machines that create fake seals, signatures, or marks.

Forging money is a class 5 felony in Colorado.
