Colorado Ancillary Probate

When someone dies owning real estate in more than one state, the estate can face probate in each state where property sits. The main case in the state where the person actually lived is called domiciliary probate. A second case opened in another state, only to deal with property located there, is called ancillary probate. Colorado ancillary probate is the version of that second case handled by a Colorado court.

For families connected to Colorado, this comes up in two directions:

A Colorado resident died owning property in another state.
An out-of-state resident died owning property physically located in Colorado.

Both situations turn on the same rule, and both usually need this guide. If you are settling the whole estate rather than just the Colorado piece, start with the Colorado probate guide for the full process.

What Is Ancillary Probate?

Ancillary probate is a secondary probate proceeding opened in a state where the deceased owned property but did not live.

Why It Is Required

Real property is governed by the law of the state where the land physically sits, not the state where the owner lived. A probate court in the home state has no authority to move a deed to Colorado land, and a Colorado court has no authority over land in another state. To transfer Colorado real estate, a Colorado court has to act. That is the whole reason ancillary probate exists.

What It Covers

A Colorado ancillary case typically deals with:

Colorado real estate titled in the deceased person's sole name
Mineral or royalty interests under Colorado land
Certain tangible personal property physically located in Colorado
Business interests based in Colorado, depending on how they are held

What It Does Not Cover

Property in the home state, which the domiciliary probate handles
Property in a third state, which needs its own ancillary case
Assets that pass outside probate entirely, such as a beneficiary deed, payable-on-death accounts, jointly titled property, or trust property

When Colorado Ancillary Probate Is Needed

Ancillary probate in Colorado is generally necessary when all of these are true:

The deceased did not live in Colorado at death
The deceased owned Colorado real property, mineral interests, or titled Colorado assets in their sole name
Those assets did not pass automatically through a beneficiary form, joint title, or a trust
A title company, buyer, or transfer agent needs a court record showing who has the right to sell or convey

Common examples:

A Texas resident who kept a mountain cabin in Summit County
An Arizona retiree who still owned a rental house in Denver
A Kansas resident who inherited mineral rights under Weld County land

If the person lived in Colorado and owned property in another state, the flip side applies: Colorado runs the domiciliary probate, and the other state's court handles ancillary probate for the out-of-state land. That second case follows the other state's rules, not Colorado's.

The Colorado Ancillary Probate Process

Colorado is a Uniform Probate Code state, and its probate rules sit in the Colorado Revised Statutes, Title 15. The mechanics below follow that framework.

Step 1: Open (or Confirm) Probate in the Home State First

The domiciliary case in the deceased person's home state normally has to be open, or far enough along to produce certified documents, before the Colorado case can proceed. From the home-state court you will need certified copies of:

The will, if there is one
The order admitting the will to probate, or appointing the personal representative
The letters testamentary or letters of administration

"Certified" means copies bearing the issuing court's seal and a certificate of authenticity, not plain photocopies.

Step 2: File in the Colorado County Where the Property Sits

The Colorado case is filed in the District Court of the county where the property is located, with one exception: in the City and County of Denver, decedent's estate matters go to the standalone Denver Probate Court (C.R.S. 15-10-201(10)). Colorado has no separate county-level probate court anywhere else. If Colorado property is in more than one county, coordinate venue with a Colorado attorney, because the county where the property sits controls.

The filing usually includes an authenticated copy of the foreign will and the home-state order, an application to admit the will or appoint a representative in Colorado, and the docket fee (a first filing to open a decedent's estate runs $229 under C.R.S. 13-32-102, per the state's fee schedule).

Step 3: Admit the Foreign Will and Establish Authority in Colorado

Because Colorado follows the Uniform Probate Code, a will already proved in the home state is generally admitted here on the strength of that authenticated record, and the foreign personal representative can be recognized to act over the Colorado property. Colorado can open the case informally with the court registrar, without a hearing (C.R.S. 15-12-301), when the paperwork is clean and uncontested; a formal proceeding before a judge (C.R.S. 15-12-401) is the escalation path if the will is questioned or the record is incomplete. The result either way is Colorado authority: letters issued by the Colorado court that let the representative act on the Colorado property. This guide keeps the statute references generic where Colorado's exact foreign-will section is not confirmed in our source data, so confirm the precise citation with a Colorado attorney.

Step 4: Administer and Transfer the Colorado Property

With Colorado letters in hand, the personal representative can:

Publish notice to Colorado creditors if the property is being administered here (Colorado's claim window runs at least four months from first publication, C.R.S. 15-12-801)
Prepare and record a personal representative's deed transferring the Colorado real estate to the beneficiaries, or sell it and distribute the proceeds
Clear title so a title company will insure a sale

Once the Colorado piece is administered and closed, the home-state case can complete the overall distribution.

Simplified and Small-Estate Alternatives

A full ancillary case is not always required for the Colorado assets.

Collection of Personal Property by Affidavit

Colorado's small-estate affidavit reaches personal property only, never real estate. Under C.R.S. 15-12-1201, a successor can collect a deceased person's personal property by sworn affidavit (form JDF 999) when the value of the estate subject to disposition by will or intestate succession, wherever located, less liens, is $88,000 or less for a 2026 death, at least 10 days have passed since death, and no personal representative has been appointed or applied for anywhere. The affidavit is notarized and handed to the holder of the property, not filed with a court. The full mechanics are in the Colorado small estate affidavit guide.

This can matter for an out-of-state estate whose only Colorado asset is, say, a Colorado bank account or brokerage account. If the estate qualifies, the affidavit may collect that personal property without any Colorado court case at all. It cannot move Colorado real estate.

Summary Administration

If a Colorado case is opened but the entire estate, after liens, does not exceed the family protections, funeral and last-illness expenses, and administration costs, the personal representative can distribute and close quickly through summary administration (C.R.S. 15-12-1203). This is a full-estate shortcut, distinct from the affidavit.

Alternatives That Avoid Ancillary Probate

Most ancillary probate is preventable while the owner is alive. If you own Colorado real estate and live elsewhere, these tools can keep that property out of a future Colorado court case.

Colorado Beneficiary Deed (Transfer-on-Death Deed)

Colorado's transfer-on-death tool for real estate is the beneficiary deed under C.R.S. 15-15-402. An owner records a deed naming who receives the property at death; during life the owner keeps full control and the beneficiary has no interest. At death the property passes to the named beneficiary outside probate, so no ancillary case is needed for that parcel. It must be recorded before death with the clerk and recorder in the county where the property sits. The Colorado transfer-on-death deed guide and the how to avoid probate in Colorado guide cover the recording steps and the Medicaid and creditor caveats.

Living Trust

A revocable living trust that holds title to the Colorado property passes it to the beneficiaries at death without probate in any state. One trust can hold real estate in several states, so a successor trustee can act everywhere without opening a second court case. The catch is funding: the deed has to actually be retitled into the trust, or the trust avoids nothing. See the Colorado revocable living trust guide.

Joint Tenancy

Colorado real estate held in joint tenancy with right of survivorship passes to the surviving co-owner at death, outside probate, when the deed says so expressly (C.R.S. 38-31-101). It is simple, but adding a co-owner gives that person present ownership and exposes the property to their creditors, so use it deliberately.

Cost and Timeline

Cost. Colorado is one of the cheaper probate states. There is no probate tax and no statutory fee percentage. Court docket fees are flat statewide amounts under C.R.S. 13-32-102 ($229 to open a decedent's estate), and personal representative and attorney pay follows a reasonable compensation standard (C.R.S. 15-10-602 and 15-10-603), not a percentage of the estate. Attorney fees for an uncontested ancillary matter vary with complexity. The Colorado probate costs guide breaks down the buckets.

Timeline. An uncontested Colorado case opened informally often runs several months; the four-month creditor period and a six-month minimum before closing set the practical floor. Because ancillary probate has to coordinate with the home-state case, the overall timeline is usually driven by whichever state moves slowest. Colorado law allows probate, testacy, and appointment proceedings to be commenced generally within three years after death (C.R.S. 15-12-108), so do not treat a delay as harmless.

Practical Tips

Confirm the property is actually in probate. Pull the recorded deed before assuming a court case is needed. If title already shows joint tenancy, a recorded beneficiary deed, or trust ownership, the property may pass with no ancillary probate at all.

Order extra certified copies. The Colorado filing needs authenticated copies from the home-state court, and each institution and county recorder may want its own. Request several early.

Check every Colorado county. Mineral and royalty interests under Colorado land are easy to miss and are often discovered only when administration begins. Search the deed records in each county where the deceased may have owned an interest.

Coordinate the two cases. The Colorado attorney and whoever handles the home-state probate will need documents from each other at several points. Good communication between them saves weeks.

Work with a Colorado probate attorney. Ancillary matters involve two states' rules at once. A Colorado attorney familiar with Title 15 can confirm venue, the correct foreign-will procedure, and whether the affidavit route fits.

Frequently Asked Questions

What is ancillary probate in Colorado?

Ancillary probate is a second probate case opened in Colorado to transfer Colorado property owned by someone who lived and was primarily probated in another state. Because Colorado land is governed by Colorado law, a Colorado court has to act before the title can move.

Do I have to open ancillary probate for a Colorado bank account?

Not necessarily. Colorado's small estate affidavit (JDF 999, C.R.S. 15-12-1201) can collect personal property such as a Colorado bank or brokerage account when the estate is $88,000 or less for a 2026 death, 10 days have passed, and no personal representative has been appointed. The affidavit cannot transfer Colorado real estate.

Which Colorado court handles ancillary probate?

The District Court of the Colorado county where the property is located, except in the City and County of Denver, where the standalone Denver Probate Court hears decedent's estate matters. Colorado does not use a separate county-level probate court anywhere else.

How do I avoid ancillary probate on my Colorado property?

While you are alive, record a Colorado beneficiary deed (C.R.S. 15-15-402), hold the property in a funded living trust, or title it in joint tenancy with right of survivorship. Any of those can pass the property at death without a Colorado court case.
