What changed

Colorado Senate Bill SB26-013, currently in draft status, seeks to amend the definition of bigamy within the state's criminal statutes. Specifically, the bill proposes to remove cohabitation as a factor that can establish the commission of bigamy. This change would narrow the scope of the bigamy offense as defined in Colorado law.

This legislative proposal, if enacted, would impact how bigamy is prosecuted in Colorado. Legal professionals and law enforcement agencies will need to be aware of the revised definition of bigamy. As the bill is still under consideration, its final form and effective date are yet to be determined. No specific compliance deadlines or penalties are mentioned in the provided summary, as it pertains to a proposed legislative change.
