Colorado Separation Date Calculator

Colorado does not legally recognize a "date of separation" for property division purposes the way states like California do. Under C.R.S. § 14-10-113, marital property includes all assets acquired during marriage until a court enters a formal decree—either dissolution or legal separation. Physical separation, even for years, does not create a property cutoff date in Colorado.

Yes, Colorado allows both dissolution of marriage and legal separation proceedings while spouses continue living in the same residence. There is no requirement to physically separate before filing. Many Colorado couples begin the divorce process while cohabitating due to housing costs, though attorneys often recommend one party move out if tensions are high to avoid complications.

Physical separation has no effect on property division in Colorado. All property acquired during marriage—including during extended periods of living apart—remains marital property subject to equitable division. Only a formal Decree of Legal Separation creates a legal cutoff date. Without this court order, assets you acquire and debts your spouse incurs continue accumulating as marital property.

No, Colorado has no mandatory separation period before filing for dissolution of marriage. Either spouse can file immediately after meeting the 91-day residency requirement. However, after filing, Colorado imposes a mandatory 91-day waiting period before the court can enter a final decree, per C.R.S. § 14-10-106(1)(a)(III). This cooling-off period begins when the respondent is served.

Since Colorado does not use a separation date for property division, proving separation timing is less critical than in other states. The relevant dates are the filing date of the petition and the date the decree is entered. However, courts may consider separation circumstances when evaluating equitable factors for property division, such as one spouse's economic contributions after physical separation.

The date of physical separation itself does not directly affect spousal maintenance calculations in Colorado. Courts consider the marriage duration from wedding to decree entry when applying Colorado's statutory maintenance guidelines under C.R.S. § 14-10-114. However, each spouse's financial circumstances at the time of decree—potentially influenced by separation—factor into maintenance determinations.

Debt incurred after physical separation but before a Decree of Legal Separation or Dissolution remains marital debt in Colorado. Courts have ruled that all debt acquired during marriage is marital debt regardless of living arrangements. This includes student loans, credit card debt, and vehicle loans. Only a formal court decree—not moving out—stops marital debt accumulation.

Because Colorado does not use separation date as a property cutoff, disputes about when separation occurred are less common than in other states. The controlling dates—petition filing and decree entry—are documented court records. However, parties may dispute separation timing when arguing equitable factors, such as whether post-separation contributions should influence division percentages.
