If your spouse lives in another state, you can usually still divorce in Colorado (filing where you live) as long as you meet the 91-day residency rule, but for a Colorado court to order maintenance, child support, or divide out-of-state property, it generally needs "personal jurisdiction" over your spouse, obtained through proper service, their consent, or Colorado's long-arm statute. Service on an out-of-state spouse gives them 35 days (not 21) to respond. Military families have special rules: the federal Servicemembers Civil Relief Act can pause proceedings during active duty, military pensions have their own division rules, and residency/domicile can be more complicated for service members.
