The two 91-day rules
One spouse must have lived in Colorado for 91 days before filing, and no decree can enter until at least 91 days after the case starts (service or joint filing). That's the legal floor: about three months, minimum.
Where LLF comes in: We use the mandatory waiting period productively — disclosures, valuations, and agreement drafts — so day 92 is a finish line, not a starting gun.
