Pet Custody Laws in New Mexico: What Happens to Your Pet in a Divorce
August 1, 2026
When a relationship ends, few questions feel as painful as “who gets the pet?” For many people in New Mexico, a dog or cat is not simply a possession — it is a daily companion, a source of comfort, and a genuine member of the household. Yet when you bring that question into a New Mexico courtroom, the law answers it in a way that often surprises people: your pet is legally treated as property, not as a family member.
Understanding exactly how New Mexico handles pet custody — and how you can protect your interests before, during, and after a split — can make a real difference in the outcome. This guide walks you through the current legal framework, what judges actually consider, and what steps you can take right now to put yourself in the strongest possible position.

Are Pets Considered Property in New Mexico?
Yes — under New Mexico law, pets are legally classified as personal property. Because pets are considered property under the law, the state of New Mexico does not have any laws pertaining to “custody” for animals, in contrast to the rules that govern children. This distinction matters enormously once you enter the court system.
The statutory foundation for this classification is found in New Mexico Statutes Annotated § 77-1-1, which explicitly categorizes dogs, cats, domesticated fowl, and birds as personal property. That single statute shapes everything that follows in a divorce or separation dispute involving an animal.
What this means practically is that a New Mexico court will approach your pet the same way it approaches a piece of furniture or a vehicle — as an asset to be allocated during property division, not as a being with independent legal interests. Under the law, pets are considered to be personal property, capable of human ownership and control, and courts working under that law only strictly have authority to award a pet to one owner or the other.
New Mexico is also a community property state, which adds another layer. If you acquired the pet during the marriage, it is generally presumed to be community property subject to equal division. If you owned the pet before the marriage, you may be able to argue it is separate property — though that argument depends on documentation and the specific facts of your case.

Does New Mexico Consider the Pet’s Best Interest in Custody Disputes?
Not as a formal legal standard. Even though there are no laws in New Mexico for pet custody, there are some solutions to help you decide what is the best option for you and your pets. The “best interest of the pet” is not a codified test the way “best interest of the child” is under New Mexico Statutes § 40-4-9.
Because pets are personal property legally, the courts do not have to consider their best interest in awarding ownership. However, some courts have started to do just that, looking at which owner the pet spends the most time with or who takes care of the pet primarily. New Mexico judges have discretion in how they weigh evidence, which means a compassionate judge may informally consider the animal’s welfare even without a statute requiring it.
If the divorce goes through court hearings, there is not currently a national or statewide precedent for assigning pet custody. There are, however, judges sprinkled around the country who have made decisions based on “the best interest of the pet” — the same consideration that participation in mediation will present.
This gap between the emotional reality of pet ownership and the legal reality of property classification is exactly why many New Mexico family law attorneys recommend resolving pet disputes outside of court whenever possible. A negotiated agreement gives both parties far more control over the outcome than leaving the decision to a judge who is legally bound to treat your dog like a dining room table.

How Pet Custody Is Decided in New Mexico Divorce Cases
When a divorcing couple cannot agree on who keeps a pet, a New Mexico judge will apply property division principles rather than custody law. The court’s starting point is whether the animal is community property or separate property.
If a couple is unable to agree on who should have custody of the family pet, the courts would typically give the animal to the person in the couple who was the primary caregiver for the animal during the marriage. Evidence of primary caregiving can include veterinary records in your name, receipts for food and supplies, grooming appointments, training records, and testimony from witnesses who observed your daily routine with the animal.
If there are children involved who have a close relationship with the pet, the judge may decide to give the pet to the spouse who will have primary custody of the children in order to preserve the continuity of that relationship for the children. This is one area where the animal’s welfare does enter the analysis — not as a right the pet holds, but as a factor in protecting the children’s wellbeing.
Other factors a New Mexico judge may weigh informally include:
- Who paid for the pet (purchase price, adoption fees)
- Whose name appears on registration, microchip records, or licensing documents
- Who scheduled and attended veterinary appointments
- Which spouse’s living situation is better suited to the animal’s needs (yard space, work schedule, proximity to a dog park)
- The pet’s established daily routine and which home can maintain it
Pro Tip: Start gathering documentation early. Vet records, purchase receipts, licensing registrations, and even dated photos of you caring for your pet can all serve as evidence of primary caregiving if the dispute reaches a judge.
New Mexico’s Animal Legal & Historical Center notes that courts across the country are beginning to take a more nuanced approach to pet cases, and New Mexico judges are not immune to that broader shift in legal culture.

Can You Get Shared Custody or Visitation for a Pet in New Mexico?
Technically, a New Mexico court cannot order shared custody or visitation for a pet the same way it can for a child. Courts working under property law only strictly have authority to award a pet to one owner or the other. To grant shared custody or visitation of the couple’s pets would be exactly the same as dividing any other piece of property — and courts do not typically order “shared use” of personal property.
That said, nothing stops two parties from voluntarily agreeing to a shared arrangement and incorporating it into their divorce settlement. Some pets share an equal bond with both owners. If spouses can amicably communicate about their pets, they can work together to create a schedule in which they both get to spend time with the pet. Keep in mind that inconsistency can be hard for animals, and a simple plan is usually the best option — such as one week on, one week off. This way, both owners can remain in their lives and vice versa.
Beyond shared arrangements, there are two other common structures:
- Primary custody with visitation: In cases where it might not be feasible for the pet to take turns between households, one person may take on primary custody while the other enjoys “visitation.” This is often a more stable option for the pet.
- Sole custody: If one owner has a stronger bond with the pet or is better equipped to care for them, sole custody is probably the best choice. However, regular updates and visitation can be beneficial for the non-custodial party if both parties are agreeable.
Some courts have even awarded “petimony,” an alimony-like payment for maintenance costs of the pet to the custodial owner from the non-custodial owner. While this is not an established New Mexico practice, it illustrates the creative solutions that are available when both parties negotiate rather than litigate. For comparison, see how New York and Washington have approached similar questions.
What Happens to Pet Custody for Unmarried Couples in New Mexico?
If you and your partner were never married, the situation is legally simpler in one sense — and more difficult in another. There is no divorce proceeding, so there is no community property framework to work within. Often, especially when there is no legal dissolution due to marriage, a pet is viewed by the courts as property. This means the dispute would typically be handled as a civil matter, not a family law matter.
In a civil dispute between unmarried partners, the person who can demonstrate legal ownership of the pet is most likely to prevail. Ownership evidence includes:
- The original purchase or adoption contract bearing your name
- Veterinary records listing you as the owner
- Microchip registration in your name
- City or county pet licensing records
- Bank or credit card records showing you paid for the animal
Without a marriage, you cannot rely on community property arguments. The partner whose name does not appear on any documentation is in a much weaker legal position, regardless of how much time or money they invested in the pet’s care. Unfortunately, a pet is often viewed by the courts as property, and the conversation on pet custody in relation to a divorce decree can proceed as the couple and their agents and mediators find best.
Mediation is often the most practical path for unmarried couples, since the cost and uncertainty of civil litigation over a pet can quickly outweigh the outcome.

How a Prenup or Pet Custody Agreement Affects New Mexico Courts
A prenuptial agreement that specifically addresses pet ownership is one of the most reliable tools available to couples in New Mexico. Because pets are property under state law, you can include them in a prenup just as you would any other asset. If the agreement is properly drafted and executed, a New Mexico court is very likely to honor it.
Similarly, a standalone pet custody agreement — sometimes called a pet protection agreement — can be incorporated into a divorce settlement or cohabitation agreement. The conversation on pet custody in relation to a divorce decree can proceed as the couple and their agents and mediators find best. When both parties sign a written agreement that specifies ownership, visitation schedules, and financial responsibilities, that document gives a court clear guidance and reduces the chance of a contested hearing.
For a pet custody agreement to hold up in New Mexico, it should address:
- Which party is designated as the primary owner
- Any visitation or shared-time schedule, with specific days and handoff logistics
- How veterinary costs will be divided
- What happens if one party relocates out of state
- How disputes about the agreement will be resolved (e.g., mediation first)
Verbal agreements carry little legal weight if the relationship deteriorates. A written, signed document — ideally reviewed by a family law attorney — is far more enforceable. If you have a sensitive pet, you need to think about how the transitions will affect the animal and their secure attachments. A detailed written plan protects both the people involved and the animal.
Pro Tip: If you are entering a long-term relationship and already own a pet, consider a simple cohabitation agreement that names you as the sole owner. This one step can prevent a costly legal dispute later if the relationship ends.

Recent and Pending Pet Custody Law Changes in New Mexico
As of June 2026, New Mexico has not enacted a dedicated pet custody statute. The state still relies on general property law principles when courts are asked to resolve animal ownership disputes in divorce.
There have been prior legislative attempts to change this. Regardless of veterinary records or any other records regarding an animal, in a divorce a judge would be able to decide who owns the pet if House Bill 448 were passed. That bill, introduced in 2019, did not become law, but it signaled growing legislative interest in the issue. One of the five lawmakers behind the bill said pets should not automatically go to the person whose name is on the pet’s papers or the vet bills. “It will be a judge who decides who can consider, who’s really been the caregiver of the animal, is closest to it,” said Joanne Ferrary of Las Cruces, who headed up the bill.
On the broader animal law front, the 2026 New Mexico legislative session saw activity around companion animal welfare. The Companion Animal Rescue Effort (CARE), operated by Animal Protection New Mexico, has helped domestic violence survivors stay safe with their pets by operating a helpline that connects them to secure temporary housing and care for companion animals. The State of New Mexico has long recognized the value of these services, but without adequate funding from the Legislature in the 2026 session, these critical services for survivors and their pets are at risk.
Separately, House Bill 51 aimed to save New Mexico’s Affordable Spay/Neuter Law by removing the repeal date of July 1, 2026. The Affordable Spay/Neuter Law generates funding through fees paid by pet food manufacturers to curb dog and cat overpopulation — a related but distinct area of animal law reform in the state.
The national trend is moving toward greater legal recognition of pets as more than mere property. States like California and Georgia have taken steps in this direction, and advocates in New Mexico continue to push for similar reforms. Until a dedicated statute passes, however, New Mexico pet owners must work within the existing property law framework — making proactive agreements and strong documentation more important than ever.
If you are navigating a separation in New Mexico and a pet is involved, the most important step you can take is to consult a licensed family law attorney before the dispute escalates.
