Pet Co-Ownership Agreement: Complete Guide with Free Template

You adopted a dog together. You split the adoption fee. Then you break up or move apart — and now you're fighting over who gets the dog. A pet co-ownership agreement prevents exactly this.

What Is a Pet Co-Ownership Agreement?

It's a written contract between two or more people who co-own a pet. It spells out who is responsible for what — financially and practically — and what happens if the owners stop living together. Think of it as a prenup for your pet.

Who Needs One?

Roommates who adopted a dog together. Couples who got a cat. Friends who split the cost of a horse. Anyone who shares ownership of an animal and wants to avoid a messy legal fight later.

What to Include

1. Primary Ownership: Who is the legal owner on paper? Is it joint ownership or does one person have primary custody?

2. Expense Split: Food, vet bills, grooming, insurance, daycare — who pays what percentage?

3. Daily Care: Who walks, feeds, and cleans up after the pet? What's the schedule?

4. Emergency Care: Who is authorized to make medical decisions? What's the spending limit before consulting co-owners?

5. Custody If You Separate: The most important clause. Who gets the pet? Is there shared custody? Visitation rights?

Is It Legally Enforceable?

Pets are considered property under US law. A signed agreement about property division is enforceable — and courts have increasingly recognized pet custody arrangements in recent years. Having it in writing makes it far more likely to be honored.
