For millions of Canadian couples, pets are family. They sleep on the bed, they come on vacation, and their Instagram accounts have more followers than yours. But here’s the uncomfortable truth: in the eyes of Canadian law, your dog is furniture.
That’s not an exaggeration. Under both federal and Ontario provincial law, pets are classified as personal property. In a separation, a dispute over who keeps the dog is legally no different from a dispute over who keeps the couch. There’s no concept of “pet custody,” no consideration of the animal’s best interests, and no shared custody arrangements built into the law.
For couples who consider their pets to be genuine members of the family, this is a serious gap, and it’s one that a marriage contract can fill.
How Canadian Courts Currently Handle Pet Disputes
When couples separate without a prenup that addresses pets, the outcome depends on who can prove ownership. Courts look at factors like who purchased or adopted the animal, whose name is on the veterinary records, and who has been the primary caregiver. But these factors are applied through a property lens, not a welfare lens.
Canadian courts have generally declined to apply a “best interests of the pet” analysis, even when litigants have asked for it. In the 2019 Ontario case of Henderson v. Henderson, the court explicitly stated that pets are chattels under the law and refused to treat the custody analysis the way it would for a child. While some jurisdictions internationally have moved toward recognizing animals as sentient beings in family law, Canada hasn’t followed suit.
The result is that pet disputes in divorce are unpredictable, emotionally draining, and often disproportionately expensive relative to the “property value” of the animal. Litigation over a pet can cost thousands of dollars in legal fees for an asset that, on paper, may be worth a few hundred.
What a Prenup Can Do for Your Pets
A marriage contract is the single most effective way to protect your pet in a separation. While courts treat pets as property by default, a contractual clause that both parties agree to voluntarily carries significant weight.
In your prenup, you can specify who retains primary ownership of the pet in a separation. You can outline a shared care arrangement, including a schedule for time with the animal. You can address financial responsibilities for veterinary care, food, and insurance. You can include provisions for pets acquired during the marriage, not just those brought into it. And you can designate a decision-making framework for major health decisions about the animal.
These clauses are increasingly common in modern marriage contracts. To learn more about how the I Do Prenup platform works, visit How It Works.
Pets Acquired During the Marriage
Pets brought into the marriage by one partner are generally easier to address, as they’re typically considered that partner’s property. The real complexity arises with pets adopted or purchased together during the marriage.
Without a prenup, there’s no clear legal framework for determining who gets a jointly acquired pet. The court may look at who paid the adoption fee, who provides the day-to-day care, or whose name is on the microchip registration. But these factors don’t always point in the same direction, and the court’s decision may not align with what either partner considers fair.
A marriage contract can pre-emptively resolve this by establishing criteria for pet ownership decisions. For example, you could designate the primary caregiver as the default owner, or agree to a shared arrangement with specified schedules.
The Emotional Cost of Pet Disputes
Beyond the legal and financial costs, fighting over a pet in a divorce takes an enormous emotional toll. For many couples, the pet is the last shared connection, and disputes over the animal can become proxy battles for unresolved relationship issues. A prenup removes this flashpoint entirely. By deciding the arrangement during a time of love and cooperation, both partners avoid making this decision during the worst period of their relationship.

Are Pet Clauses Enforceable?
Yes, with caveats. Since pets are legally classified as property in Ontario, clauses that address pet ownership in a marriage contract are treated like any other property division clause. Courts will generally enforce them if the agreement meets all standard enforceability requirements: written, signed by both parties, and witnessed.
Shared care arrangements are less certain legally, since courts aren’t obligated to enforce ongoing obligations the way they are with child custody orders. However, most couples who include these clauses in a prenup find that having the terms documented prevents disputes from ever reaching court.

Frequently Asked Questions
Q: Can I include my pet in a prenup in Ontario?

Q: Will a Canadian court enforce a shared pet custody arrangement?
Courts generally enforce property division clauses in marriage contracts. While ongoing shared care arrangements have less legal precedent than simple ownership designations, having the terms documented in a signed agreement significantly reduces the likelihood of a dispute.
Q: What if we adopt a pet after signing the prenup?
You can amend your marriage contract at any time to address new circumstances, including new pets. Both partners must agree to the amendment, and it must be in writing, signed, and witnessed.
