E-signature laws in Colorado

Colorado adopted UETA in 2002, establishing electronic signatures as legally valid and enforceable for most transactions throughout the state. Colorado's technology sector in Denver and Boulder, combined with its business-friendly regulatory environment, makes e-signatures common for technology companies, real estate transactions, and commercial contracts. The federal ESIGN Act provides a concurrent baseline for interstate transactions.

Colorado Uniform Electronic Transactions Act (C.R.S. § 24-71.3-101 through 24-71.3-119) (2002)

Key provisions

• Electronic signatures are legally equivalent to handwritten signatures and may not be denied legal effect solely because they are electronic.
• Electronic records satisfy any Colorado statute or rule requiring information to be in written form.
• Parties must consent — expressly or by conduct — to conduct a transaction electronically.
• Colorado law recognizes that an electronic record or signature is attributable to a person if it was that person's act.
• Contracts formed electronically are valid and enforceable under Colorado law.
