The bill passed & Rosie is still not home.
Rosie's case exposed a gap in Illinois law: companion animals could be treated as property without a clear way for courts to consider caregiving history, attachment, or well-being. That gap helped inspire HB 4540, the Companion Animal Custody Equity Act. Now the bill has passed both chambers of the Illinois General Assembly. But Rosie, the senior puggle at the heart of this movement, is still separated from her primary caregiver. Help bring Rosie home and protect other companion animals from being reduced to property alone.
One Dog. One Verdict. One Movement.
When Rosie was separated from her primary caregiver through a court ruling that treated her as property, Tameer Siddiqui — Rosie’s longtime caregiver — founded the Rosie's Law Initiative. She originated the legal concept for what became the Companion Animal Custody Equity Act, drafted the original proposal, secured legislative sponsorship, and helped move the reform into HB 4540, now passed by both chambers of the Illinois General Assembly. What began in a Chicago courtroom became a campaign to ensure that no companion animal is ever reduced to furniture again. Rosie's case didn't just expose a gap — it created the blueprint for closing it.
1 legislative fix to change how courts see your companion animal.
One bill, HB 4540, that asks Illinois courts to weigh care, cost, and connection — not treat a companion like a sofa.
If you were never married, your companion animal was legally furniture. HB 4540 just changed that.
Illinois already gives family courts the authority to consider a companion animal’s wellbeing — but only in divorce proceedings. If you were never married, that protection did not exist. Your years of care, veterinary bills, and documented bond: legally irrelevant. HB 4540 — the Companion Animal Custody Equity Act — just passed both chambers of the Illinois General Assembly. It extends that same consideration to civil disputes between unmarried partners. It asks courts to evaluate four factors: who provided care, who bore financial responsibility, who exercised day-to-day control, and what arrangement offers the animal the greatest continuity and stability. This is not about sentiment. It is about applying a standard that already existed — to everyone it should have covered all along.
Rosie's law is how Illinois rethinks pet custody.
HB 4540 asks courts to weigh who fed, who paid, who loved — not just whose name is on the adoption papers.
Legal advocates, clinicians, and caregivers speak out
Rosie's Law represents a crucial shift in how we protect companion animals. By recognizing caregiving involvement and emotional bonds, Illinois can lead the nation in animal welfare legislation.

Animal welfare attorney and advocate
This framework protects primary caregivers from coercive control while ensuring companion animals stay with the people who care for them most. It's a common-sense update to outdated property law.

The four-factor approach—care, cost, control, and stability—reflects what actually matters in a companion animal's life. This is the model other states should adopt.

Director, Companion Animal Ethics Center
Having worked with families fighting over pet custody, I've seen the harm caused by treating animals as property. Rosie's Law puts their wellbeing first, where it belongs.
Lisa Hernandez
Animal welfare advocate and rescuer
Illinois has a chance to set a national precedent. Rosie's Law does that by centering the animal's emotional wellbeing alongside practical care factors. That's transformative legislation.

Companion animal custody disputes are common. The law finally caught up.
Every one of these cases involves a living being whose welfare the court was previously not required to consider — unless the parties were married. HB 4540 closes that gap. Now we need your signature to show lawmakers that Illinois is ready for what comes next.
