Plain-language change summary

The recent amendments to SB 13 involve clarifying the definition of bigamy by specifying that marrying or cohabiting with another person while already married or in a civil union constitutes the offense of bigamy. The bill now clearly includes cohabitation as a factor in bigamy cases, which aligns legal definitions with current relationship practices. Additionally, the bill repeals a section that was likely outdated, streamlining the law regarding marital status. These changes matter because they make the law more relevant to today's relationships and reinforce the seriousness of bigamy in various forms.
