Where to File for Divorce in Colorado: Venue Rules Explained

Filing in the wrong county is one of the most common mistakes pro se filers make in Colorado — and it can cost you weeks of delay while the case is transferred. Colorado's venue rules are straightforward once you understand the two questions every filer needs to answer: which court has jurisdiction, and which county is the right one.

The Residency Requirement Comes First

Before any Colorado court will hear your case, at least one spouse must have been domiciled in the state for a minimum of 91 days immediately before filing. This is a hard statutory requirement under C.R.S. Section 14-10-106(1)(a)(I) — no judge can waive it.

If you have minor children and need the court to make custody and parenting time orders, there is a separate, stricter test: the children must have lived in Colorado for at least 182 days (six months) before filing under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA). If the children are under six months old, they must have lived in Colorado since birth.

Which County: The Venue Rule

Once residency is established, you file in the District Court of the county where either you or your spouse currently lives. Under Colorado Rule of Civil Procedure 98, the case should be commenced in the county where one of the parties resides.

If you and your spouse live in different counties, you can file in either one. There is no legal advantage to filing in your own county versus your spouse's — the same Colorado statutes apply statewide.

When Children Affect the County Choice

If you are separated and your children live primarily with one parent, filing in the county where the children reside is the safest choice. While the statute technically allows filing in either spouse's county, courts have stronger jurisdictional footing over parenting matters when the children live in that county. Some family law practitioners recommend defaulting to the children's county to avoid a transfer motion from the other parent.

What Happens If You File in the Wrong County

Filing in an incorrect county does not kill your case. The court retains subject matter jurisdiction — it can still process a dissolution. But your spouse can file a timely motion to change venue, and the judge will likely grant it if neither party lives in the county where you filed. This means your case gets transferred, adding weeks or months of delay.

If neither party objects to the venue, the case proceeds as filed. The objection must be raised early — waiting until the case is well underway typically waives the right to challenge venue.

Denver: A Filing Exception

Denver has a unique court structure. Denver District Court handles dissolution of marriage cases and uses the standard Colorado Courts E-Filing (CCE) system. However, Denver County Court operates on a separate system (File & Serve Xpress). Make sure you are filing in Denver District Court, not Denver County Court.

Practical Filing Steps

1. Confirm residency: verify at least one spouse has lived in Colorado for 91+ days
2. Identify the county: determine where you (or your spouse) currently live
3. File at the District Court: bring or e-file your petition (JDF 1011), case information sheet (JDF 1000), and summons (JDF 1012 if filing solo)
4. Pay the filing fee: $260 for the petition (as of January 2025, after the HB24-1286 increase)
