Pets and Divorce in Colorado

Colorado has no best interest standard for pets, and the 2026 bill that would have created one died in committee. That makes what you negotiate more important than what you could argue.

For many people this is one of the hardest parts of a separation and one of the least well served by the law. The gap between what a pet means to you and what the law can do about it is the whole problem.

Where Pets Sit in Colorado Law

A pet acquired during the marriage is generally marital property. A pet one of you owned before the marriage, or received as a gift from someone else, is generally that person’s separate property.¹

Marital property is divided equitably along with everything else in a Colorado divorce, in light of the statutory factors. Separate property stays with the spouse who owns it.

There is no best interest of the animal standard here, and that nearly changed. House Bill 26-1131 would have directed courts, on request, to decide custody of a pet animal in a divorce based on the animal’s best interest.² It was still in the House Appropriations Committee when the legislature adjourned in May 2026, so it died there.

That is worth stating plainly because coverage written while the bill was pending may have left the impression that it passed. If you have read that Colorado adopted a pet custody law in 2026, what you read described a bill that did not.

There is also no best interest standard waiting in the wings. Any future change would need a new bill.

A handful of states have gone the other way, including California, Illinois, and Alaska. Colorado has not, and a court here is not required to weigh what is best for the animal.

What a Judge Will Actually Do

There is no formula, which is the practical consequence of having no standard. A judge deciding this is dividing property, not making a parenting decision.

What tends to carry weight is ordinary ownership evidence. Who acquired the animal and when, who paid for food and veterinary care, who is named on the registration and the microchip, and whose home the animal actually lives in.

Courts also do not generally impose shared schedules. Dividing property is about separating interests rather than keeping two people tied together, which is why Colorado property division tends to produce a clean award rather than an arrangement.

Leaving it to a judge is therefore unpredictable in a specific way. The outcome turns on records rather than on attachment, and the result is usually all or nothing.

This is the one worth settling yourselves.

A court will usually award a pet to one of you. An agreement can do things a court will not. Schedule a free consultation with Johnson Law Group and we will help you put workable terms in writing.

Why an Agreement Does More Than a Hearing

This is where the law being unhelpful turns into an advantage. The terms you agree are binding on the court unless unconscionable, and once they are set forth in the decree they are enforced by the remedies available for a judgment.³ A court will rarely design a shared arrangement, and it will usually approve one you bring.

That means you can write terms no judge would impose. A schedule, who pays for veterinary care, and who decides about treatment. Also what happens if one of you moves, and who gets first refusal if the other can no longer keep the animal.

Specificity is what makes these terms work later. Naming the animal, the days, and the cost split prevents the argument that an informal understanding invites.

Prenuptial and Postnuptial Agreements

Because a pet is property, it can be addressed in a premarital or marital agreement. The act lists terms a court will not enforce, including terms that adversely affect a child’s right to support or that violate public policy.⁴ A prenuptial agreement takes effect on marriage, and a postnuptial agreement is made during it.

This is the cleanest way to settle the question in advance. It is also a common reason people revisit a Colorado prenuptial and postnuptial agreement after acquiring an animal together.

Keep the terms to the animal and the money. Terms about children’s parenting arrangements are not binding on the court, which decides those on the children’s best interests at the time.

The agreement itself can also be challenged, on grounds the act sets out separately. A pet term is only as good as the agreement carrying it.

If There Is a Safety Concern

Animals are sometimes used as leverage, and Colorado’s protection order statutes address it directly. A civil protection order can restrain a party from harming, taking, concealing, or disposing of an animal held by the other party or their minor child.⁵ It can also specify arrangements for the animal’s possession and care, and an emergency protection order carries parallel provisions.

That exists now and does not depend on the bill that failed. A protection order needs grounds beyond a disagreement over who keeps the pet.

If an animal is being threatened or withheld to control or frighten you, raise it early rather than treating it as part of the property argument.

Frequently Asked Questions

Does Colorado have a pet custody law?

No. Pets are treated as property, and one acquired during the marriage is generally divided as marital property. House Bill 26-1131 would have created a best interest standard in 2026, but it died in committee when the session ended and did not become law.

How does a judge decide who keeps the pet?

As a property question rather than a parenting one. Ordinary ownership evidence tends to carry the weight. That includes who acquired the animal, who paid for food and veterinary care, who appears on the registration and microchip, and where the animal lives.

Can we share custody of our dog?

By agreement, yes. A court will rarely impose a shared schedule, because dividing property is about separating interests. Terms you agree are binding on the court unless unconscionable, and enforceable as a court judgment once written into the decree.

Can a prenup decide who gets the pets?

Yes, because a pet is property. A premarital or marital agreement can dispose of it, though the act lists terms a court will not enforce and the agreement itself must be validly made. Terms about children’s parenting arrangements are not binding on the court.

What if my spouse is using our pet against me?

A civil protection order can restrain a party from harming, concealing, or disposing of an animal held by the other party or their minor child. It can also specify arrangements for the animal’s care. It requires grounds beyond an ordinary dispute over who keeps the pet.
