Does it matter who the dog likes more?

Under Rosie’s Law, effective January 1, 2027, a court may consider emotional bonds alongside caregiving, safety, stability, and ownership evidence in a companion-animal possession dispute. No single factor guarantees the outcome.

My name is on the adoption papers but my ex has the dog. What can I do?

Start with a written demand for return. Our Illinois attorney-drafted demand letter is a flat $165. If it's ignored, a small-claims recovery action is the next step.

We bought the dog together. Who keeps it?

When both people have ownership evidence, the dispute is harder to predict. Many couples settle with a written pet custody agreement covering who keeps the dog, visits, and costs.

Can I just take the dog back?

Self-help can escalate things and create legal risk. Talk to an attorney before taking the dog from someone else's home.

Does a microchip prove ownership in Illinois?

It is strong evidence but not conclusive on its own. Courts consider it alongside purchase records, vet records, and who has cared for the dog.

What counts as proof of ownership

Under Rosie’s Law, effective January 1, 2027, keep evidence of shared care, emotional bonds, safety, and continuity as well as ownership documents. The Act preserves property-law principles but permits a broader assessment in companion-animal possession disputes.

Adoption contract, bill of sale, or breeder receipt in your name.
Microchip registration and city or county dog license.
Vet records listing you as the owner, and who paid the bills.
Texts or messages where your ex calls the dog yours or offers to give it back.
Photos and records showing who handled daily care.
