Legal separation and divorce in Colorado share an identical process — a $230 filing fee, a 91-day residency requirement under Colo. Rev. Stat. § 14-10-106, and a 91-day waiting period — but a legal separation ends with a Decree of Legal Separation that keeps you legally married, while divorce ends the marriage entirely. The core difference is marital status, not procedure.
Understanding the difference between separation and divorce matters because the choice affects health insurance, taxes, inheritance, and the ability to remarry. This guide explains legal separation vs divorce Colorado rules, the shared filing process, costs, and how a separation can convert to a full dissolution after 182 days. Colorado calls divorce "dissolution of marriage" and legal separation "separate maintenance" in older statutory language, but both are governed by Title 14, Article 10 of the Colorado Revised Statutes.

What Is the Difference Between Legal Separation and Divorce in Colorado?
The difference between separation and divorce in Colorado comes down to one outcome: a Decree of Legal Separation keeps you legally married, while a Decree of Dissolution of Marriage ends the marriage. Both require the same $230 filing fee, the same 91-day residency, and divide property identically under C.R.S. § 14-10-113.
A legal separation in Colorado resolves every issue a divorce resolves — property division, debt allocation, spousal maintenance, child support, and parenting time — yet the spouses remain married in the eyes of the law. This means a legally separated person cannot remarry. A divorced person can. Both proceedings are filed in District Court, not County Court, because District Courts handle all domestic relations matters in Colorado. The petition forms are nearly identical: you check a box requesting either dissolution or legal separation. Couples choose legal separation for religious reasons, to preserve health insurance eligibility, to maintain certain tax or military benefits, or because they are uncertain about ending the marriage permanently. The substantive rights and obligations created by each decree are functionally the same; only the marital-status result differs.
How Much Does It Cost to File for Legal Separation or Divorce in Colorado?
The filing fee to initiate either a legal separation or a divorce in Colorado is $230 as of January 2026, plus a non-waivable $12 e-filing fee. The responding spouse pays a $116 response fee. These amounts increased on January 1, 2025 under Colorado House Bill 2024-1286 and are identical for both proceedings.
The filing cost is the same whether you pursue separate maintenance or dissolution because both are filed as domestic relations cases in District Court. Beyond the initial fee, additional costs may include service of process ($30 to $75 if using a private process server or sheriff), parenting classes (often $50 to $75 when minor children are involved), and mediation if the case is contested. Attorney fees represent the largest variable cost in either proceeding, ranging from a few hundred dollars for limited document review to tens of thousands for fully litigated cases. If you cannot afford the $230 fee, Colorado offers a fee waiver through JDF 205 (Motion to File Without Payment) and JDF 206 (Supporting Financial Affidavit). All required JDF forms are available free from the Colorado Judicial Branch website at coloradojudicial.gov. As of January 2026, verify all fees with your local district court clerk before filing.
What Are the Residency Requirements for Legal Separation and Divorce in Colorado?
To file for either legal separation or divorce in Colorado, at least one spouse must have lived in the state for a minimum of 91 days before filing, under C.R.S. § 14-10-106(1)(a)(I). This residency rule is identical for both proceedings and establishes the court's authority to hear the case.
Residency in Colorado means physical presence in the state combined with the intent to make Colorado a permanent home. The 91-day requirement applies regardless of where the couple married. Temporary absences for business travel, vacation, or military deployment generally do not interrupt the 91-day period, as long as the filing spouse maintains Colorado as a primary residence. This residency threshold determines subject matter jurisdiction — without it, the court cannot proceed with either a separation or a divorce. A separate and longer rule applies to child custody: under C.R.S. § 14-13-201, a Colorado court has jurisdiction over parental responsibilities only if the child has lived in Colorado for at least 182 consecutive days (roughly six months) before filing. Colorado does not require spouses to live apart before filing. Spouses may file for dissolution or separation while still residing in the same household, because Colorado imposes no physical-separation prerequisite for either action.
What Are the Grounds for Legal Separation and Divorce in Colorado?
Colorado is a purely no-fault state, so the only ground for both legal separation and divorce is that the marriage is "irretrievably broken," under C.R.S. § 14-10-106. Neither spouse must prove adultery, abandonment, cruelty, or any other fault, and the court does not consider marital misconduct when granting either decree.
Because Colorado eliminated fault grounds, one spouse can obtain a divorce even if the other objects — the court need only find the marriage is irretrievably broken. The same standard applies to legal separation: a spouse seeking separate maintenance simply asserts the marriage is broken without alleging wrongdoing. Marital misconduct also has no bearing on how Colorado divides property or awards maintenance. Under C.R.S. § 14-10-113, the court divides marital property equitably based on economic factors, not behavior. Under C.R.S. § 14-10-114, spousal maintenance is calculated using a statutory formula tied to income and marriage length, again without regard to fault. This no-fault framework streamlines both proceedings, removing the contentious blame-assignment that drives up costs and conflict in fault-based states. The practical effect is that the grounds analysis is identical whether a couple chooses separation or full dissolution.
How Does the Filing Process Work for Both Proceedings?
The filing process for legal separation and divorce in Colorado is identical: file a Petition for Dissolution of Marriage or Legal Separation in District Court, pay the $230 fee, serve the other spouse, exchange financial disclosures within 42 days, and wait at least 91 days before the court enters a decree. The only difference is which box you check on the petition.
Colorado uses standardized Judicial Department Forms (the JDF series), and the essential documents are the same for both proceedings: JDF 1000 (Case Information Sheet), JDF 1101 (Petition for Dissolution of Marriage or Legal Separation), JDF 1102 (Summons), and JDF 1111 (Sworn Financial Statement). Both spouses must complete a Sworn Financial Statement disclosing income, assets, and debts; this mandatory exchange happens within 42 days of service. When minor children are involved, additional forms address parenting time and child support, and parents typically must complete an approved parenting class. For fully agreed cases, spouses can finalize without a court appearance by filing JDF 1201 (Affidavit for Decree Without Appearance of Parties) along with a proposed decree. Contested cases proceed to temporary orders hearings, mediation, and potentially trial. The 91-day waiting period under C.R.S. § 14-10-106 runs from the date the respondent is served, signs a waiver, or a joint petition is filed, and the court cannot enter a final decree before it elapses.
How Does Legal Separation Affect Health Insurance in Colorado?
The primary reason couples choose legal separation over divorce in Colorado is to preserve a spouse's health insurance coverage, because the parties remain legally married. After a divorce, federal and state law prohibit an ex-spouse from staying on an employer-sponsored health plan, but a legal separation may allow continued coverage — though this is never guaranteed.
Whether a legally separated spouse can remain on the other spouse's plan depends entirely on the insurance carrier's definition of "spouse," not on the court or the parties' wishes. Some plans treat a legal separation the same as divorce and terminate coverage; others treat any court-ordered separation as a qualifying event that ends dependent eligibility. The trend is shifting against this strategy, as fewer insurers now permit coverage of legally separated spouses. Before relying on separation to preserve insurance, contact the plan administrator and ask specifically whether you may continue covering your spouse as a dependent after a Decree of Legal Separation is entered. During the pending case, Colorado law protects existing coverage: under C.R.S. § 14-10-107(4)(b)(I)(D), neither spouse may cancel or allow health insurance for the other spouse or dependent children to lapse, and changes require 14 days' advance notice plus written agreement. If coverage ends after divorce, COBRA continuation and Colorado marketplace plans (a divorce or separation is a qualifying life event) provide alternatives.
Can a Legal Separation Be Converted to Divorce in Colorado?
Yes. Either spouse can convert a Decree of Legal Separation into a Decree of Dissolution of Marriage no earlier than 182 days (about six months) after the separation decree is entered, under C.R.S. § 14-10-120(2). The conversion requires only a motion and proof that notice was mailed to the other spouse — the other party's consent is not required.
This unilateral conversion right is a critical feature of Colorado law. Once 182 days have passed, one spouse can ask the court to convert the separation to a divorce even if the other objects, and the court "shall convert" the decree. The Colorado Judicial Branch provides JDF 1325 as the instructional guide for this process, filed in the same court that issued the original separation decree. Because the substantive issues — property, support, and parenting — were already resolved in the separation, the conversion is typically quick, simple, and inexpensive, and does not reopen the entire case unless the separation agreement specifically provided for revisiting financial terms upon conversion. Property, support, and parenting orders from the legal separation generally carry over unless modified. This conversion provision has an important practical consequence: any health insurance preserved through legal separation could be terminated by a unilateral conversion after six months. A spouse relying on separation to keep coverage should understand that the other spouse can end it by converting the decree to a divorce.
How Is Property Divided in a Legal Separation vs. Divorce in Colorado?
Property division is identical in a Colorado legal separation and divorce: both follow equitable distribution under C.R.S. § 14-10-113, meaning the court divides marital property fairly — though not necessarily 50/50 — based on economic circumstances. Both proceedings also allocate marital debt and determine spousal maintenance using the same statutory standards.
Equitable distribution means the court considers factors such as each spouse's contribution to acquiring marital property (including a homemaker's contribution), the value of property set apart to each spouse, the economic circumstances of each spouse at the time of division, and any increase or decrease in the value of separate property during the marriage. Separate property — assets owned before marriage or received by gift or inheritance — generally remains with the original owner, though any increase in its value during the marriage is treated as marital property subject to division. Spousal maintenance follows the advisory formula in C.R.S. § 14-10-114, which considers the length of the marriage and the parties' combined incomes. Child support, when applicable, is calculated under the income-shares model in C.R.S. § 14-10-115. Because these financial rules apply equally to both proceedings, the financial outcome of a legal separation can be functionally identical to a divorce — the only difference is that the separation preserves the legal marriage.
