Can My Ex Take the Dog?

How Ownership Is Usually Decided

• Who adopted or bought the dog, and whose name is on the paperwork.
• Microchip, license, and vet records.
• Who paid for food, care, and vet bills.
• Who handled day-to-day care.

Married vs. Unmarried

For married couples, a pet acquired during the marriage may be marital property, and a few states let judges consider the animal's well-being. For unmarried couples, ordinary property rules usually apply.

Illinois adds a specific exception beginning January 1, 2027: Rosie’s Law permits well-being considerations and temporary caregiving relief within companion-animal replevin proceedings. It includes qualifying partners and roommates who shared care, but does not automatically establish ownership.

Rules differ by state. Look up your state's pet custody law.

Protect Yourself Now

• Keep the dog's records somewhere your ex can't access.
• Update the microchip contact if you are the owner.
• Put any agreement to share the dog in writing.
