Pets and Divorce: Planning for Ownership, Care, and Costs

When you are separating, deciding what happens to a dog, cat, or another pet can be one of the hardest conversations. Both people may feel attached, while the practical questions are immediate: where will the animal live, who can provide daily care, and how will expenses be handled?

Pets and divorce involve legal questions about ownership alongside everyday caregiving decisions. A proposal needs to account for both. Calling an arrangement “shared custody” does not, by itself, explain what it requires or how it would be enforced.

Start by identifying the pet’s current routine, the arrangements each person can realistically provide, and the questions requiring independent advice.

Understand the Legal Questions Before Assuming the Outcome

In Illinois, Section 503(n) of the Illinois Marriage and Dissolution of Marriage Act addresses companion animals found to be marital assets. It provides for allocation of sole or joint ownership and responsibility, with consideration of the animal’s well-being. The provision excludes service animals as defined in the referenced law.

That does not mean the rules for children’s parenting time apply to pets. Nor does it mean every animal will automatically be treated as a jointly owned marital asset. Ownership, relevant agreements, and the circumstances need individual legal review.

Do not assume Illinois provisions apply to a Wisconsin case. Ask independent counsel which rules govern your circumstances, what issues a court can address, and how proposed terms should be documented.

Mediation can organize the conversation, but the mediator does not make a binding ownership ruling.

Describe the Daily Care the Pet Actually Needs

Before proposing a schedule, make a factual list of current responsibilities. Who feeds the pet, provides exercise, handles grooming, schedules veterinary appointments, and arranges care during travel?

Then consider the proposed living arrangements. A person moving into a rental may need to confirm pet restrictions. Someone changing work hours may need to research daytime care. Transport between homes may involve its own practical difficulties.

Useful questions include:

• What housing is available, and does it allow the pet?
• Who can provide care during workdays and overnight?
• What supplies and records need to be accessible?
• How will travel, illness, or an unexpected absence be handled?

If you have concerns about the animal’s health, behavior, or ability to adjust, consult the veterinarian or another appropriately qualified professional. Avoid assuming that a schedule that feels equal to the adults is necessarily suitable for the animal.

Be Specific About Routine and Veterinary Expenses

A general promise to “split everything” can leave questions later. Identify which expenses the proposal covers and what would happen before a new cost is incurred.

For example, you might discuss food, routine veterinary visits, medication, grooming, insurance, boarding, or other needs relevant to that pet. Separate known recurring expenses from estimates and unexpected costs.

An emergency-care discussion could address who contacts the veterinarian, how the other person is notified, and what happens if that person cannot be reached. Ask counsel how any proposed responsibilities should be recorded; do not assume that a payment arrangement is equivalent to spousal maintenance.

Bring recent invoices or insurance information where available. A discussion based on an actual bill is more concrete than an argument about what someone thinks care should cost.

Test a Proposed Arrangement Against Real Situations

If you are considering ongoing involvement by both people, work through how it would function. Which dates and locations are being proposed? Who transports the pet? How will schedule changes be requested? What happens during a vacation?

Consider a dog that normally stays with one person while the other travels for work. A proposed weekend arrangement may need to account for travel delays, available care, and access to medication or supplies.

These are discussion examples, not a recommendation that every couple share care. Some people may propose one primary home; others may want a different arrangement. Legal advice and the pet’s actual needs should inform the options.

Avoid relying on vague assurances where a detail matters. “We’ll figure it out” may be an honest intention, but it leaves both people without a clear procedure if they disagree later.

What If You Have a Prenuptial Agreement—or Were Never Married?

If an existing prenuptial, postnuptial, or other agreement mentions the animal, bring it to independent counsel. Ask what it means for ownership, whether its terms are enforceable, and what additional steps might be needed.

A document labeled a “pet prenup” does not establish its legal effect by its name alone. Mediation may help identify proposed arrangements, while legal drafting and advice serve separate purposes.

Unmarried partners can also have disagreements about pets. In Illinois, the Companion Animal Custody Equity Act, Public Act 104-0613, takes effect January 1, 2027. It adds provisions allowing courts to consider an animal’s well-being in possession disputes regardless of the parties’ legal status and permits mediation where appropriate.

That effective date matters. Ask counsel which rules apply when your dispute arises, rather than assuming the upcoming provisions already govern it. The relevant process also depends on the jurisdiction and the facts.

Where Mediation Can Help

A mediator can help participants identify the points of disagreement, exchange relevant information, and discuss practical proposals about the animal’s care. The mediator remains neutral and does not guarantee that a proposed arrangement will be accepted or enforceable.

CEL’s pre-decree divorce mediation service addresses proposed agreements before a divorce is final. Participants can obtain independent legal advice outside CEL sessions and have proposed terms reviewed before taking formal steps.

If safety concerns, threats involving an animal, or pressure affect your ability to participate freely, raise them privately with the provider and seek appropriate legal guidance before proceeding.
