Letters of Administration Appointment Requirements in Colorado

Requirements one by one

Informal and formal appointment

Colorado uses one personal-representative office but two ordinary appointment routes. An informal application goes to the registrar under § 15-12-301. A formal petition goes to the court and may combine intestacy or testacy findings with appointment. Section 15-12-414 supplies the formal proceeding when priority or qualification is disputed, including a challenge to someone already appointed informally.

Court and venue

Section 15-10-201(10) defines the probate forum as district court, except in the City and County of Denver, where it is the probate court. Section 15-12-201 places the first case in the decedent's Colorado domicile or residence county. For a nondomiciliary, any county containing decedent property is available. An interested person may seek transfer of an informal case when venue belongs elsewhere.

Petitioners and appointment priority

An interested person may submit the verified informal application. An interested person also may petition for formal testacy or intestacy and request appointment. Filing is not itself priority.

Section 15-12-203 begins with the person entitled under a probated will. It then moves through a devisee spouse, devisee civil-union partner, a person prioritized by a designated-beneficiary agreement, other devisees, the spouse, the civil- union partner, other heirs, and—forty-five days after death—any creditor.

An objection can be made only formally. In an apparently insolvent estate, creditors may obtain any qualified appointee. In another non-will-priority dispute brought by a substantial heir or devisee, the court may select a person acceptable to heirs and devisees holding more than half the probable distributable value, or any suitable person if they do not agree.

Qualification, nominations, and renunciations

The express qualification bars are age under twenty-one and unsuitability found in formal proceedings. Colorado does not require a nonresident to appoint a resident agent or co-representative. A domiciliary foreign representative instead receives priority, subject to the will's ability to name different representatives for Colorado and the domicile state.

Priority holders from the devisee-spouse class through other heirs may nominate a qualified person. So may an eighteen-to-twenty-year-old who would hold priority but for age. An adult can renounce appointment or nomination rights by a writing filed with the court. When several people share priority, those who do not renounce must concur in the nomination or application. A conservator or qualifying guardian may exercise those rights for a protected person or ward.

Application facts and formal disputes

Section 15-12-301 requires the informal application to state the applicant's interest; death, age, domicile, venue, family and devisee information; existing representatives; notice demands; and timeliness. An intestate application adds the no-unrevoked-will inquiry, the proposed appointee's priority, and the names of prior or equal priority holders. Appointment under a will identifies the will's probate and the proposed person's name, address, and priority.

A formal intestacy petition adopts those facts, seeks findings of intestacy and heirship, requests appointment if desired, and states whether supervised administration is sought. Under § 15-12-414, a formal priority or qualification petition stays pending informal appointment. If someone was already appointed, notice restricts that person to estate-preservation acts unless the court orders otherwise.

Notice, bond, and letters

Informal appointment has narrow preappointment notice. Section 15-12-310 names only people who demanded notice and unwaived prior or equal priority holders, then says no other notice is required. Formal priority and qualification are decided after notice to interested persons, the prior appointee, and everyone claiming priority. Ordinary hearing notice under § 15-10-401 is mailed or personally delivered at least fourteen days before hearing; qualifying publication runs once weekly for three weeks with the last publication at least fourteen days before hearing.

The informal applicant makes the statutory oath or affirmation, and the registrar appoints subject to qualification and acceptance. Before letters, § 15-12-601 requires a statement accepting the office and any required bond. Informal appointment normally requires no bond. In a formal case, a will's no-bond clause controls unless an interested person requests bond and the court finds it desirable; a will-required bond may be excused if unnecessary.

What trips people up

• A spouse is not always the second priority. A spouse who is a devisee ranks ahead of other devisees, while a spouse who is not a devisee comes later.
• Creditor priority waits forty-five days. The statute does not give a creditor immediate appointment priority at death.
• Only formal proceedings resolve objections. Informal appointment is for a priority-based, unopposed route; a priority or suitability contest belongs under § 15-12-414.
• Bond defaults differ by route. Informal appointment ordinarily has no bond, while formal appointment allows court-ordered bond subject to the will-specific rules.

Common questions

Can equal-priority heirs nominate one person?

Yes, but the nonrenouncing people who share that priority must concur. A person who does not wish to participate may file the statutory written renunciation.

Does Colorado bar a nonresident from serving alone?

No resident-agent or co-representative requirement appears in the appointment statute. A domiciliary foreign representative may hold priority under § 15-12-203(7).

Can the court appoint someone with no priority?

Yes, formally, after notice. The court first must find that people with priority failed to request appointment or nominate another and that administration is necessary, subject to the specific objection alternatives in § 15-12-203.
