HB 4540 Illinois companion animal custody permits courts to determine pet possession based on the animal's well-being and the caregiving history of the parties involved. This bill provides statutory guidance for judges to issue temporary custody or visitation orders in domestic disputes; it ensures pets are treated as more than mere property regardless of marital status.


If you are going through a divorce or separation in Illinois and facing the very real possibility of losing your pet, you already know how devastating that prospect can be. For too long, Illinois courts have treated companion animals as property, awarding them like furniture rather than recognizing the emotional bonds and care responsibilities involved. That is exactly the problem HB 4540, the Companion Animal Custody Equity Act, was written to solve. With the bill now clearing the Senate Judiciary Committee, a major legislative threshold has been crossed, bringing meaningful reform closer than ever. In this article, you will learn precisely what the committee vote means, how the bill's provisions would reshape custody determinations, who is driving this legislation forward, and what critical steps remain before HB 4540 becomes Illinois law.

TL;DR: HB 4540 Advances Out of Senate Judiciary Committee

HB 4540, the Companion Animal Custody Equity Act (also known as Rosie's Law), received a Do Pass recommendation from the Illinois Senate Judiciary Committee on May 6, 2026, and was placed on the Calendar Order of 2nd Reading on May 7, 2026. This milestone follows the bill's strong 72-38 bipartisan House passage on April 14, 2026, which incorporated House Floor Amendment No. 1. The committee clearance now positions HB 4540 for a full Illinois Senate floor vote, the final legislative hurdle before the bill can advance to the Governor.

HB 4540 Receives 'Do Pass' Recommendation from Illinois Senate Judiciary Committee, Advancing Companion Animal Custody Reform Toward Full Senate Vote

The Illinois Senate Judiciary Committee issued a Do Pass recommendation for HB 4540, the Companion Animal Custody Equity Act, on May 6, 2026. The bill was subsequently placed on the Calendar Order of 2nd Reading on May 7, 2026, positioning it for consideration before the full Illinois Senate.

The committee clearance represents a meaningful procedural milestone. In the Illinois Senate, a Do Pass recommendation from an assigned committee is not automatic; it signals that committee members reviewed the bill's legal framework, heard its policy rationale, and determined it is both constitutionally sound and ready for full chamber consideration. Bills that lack this clearance do not advance to the floor.

HB 4540 was referred to the Illinois Senate on April 15, 2026, one day after engrossment following the bill's 72-38 bipartisan House passage on April 14, 2026, which incorporated House Floor Amendment No. 1. The Senate assigned the bill to its Judiciary Committee on April 28, 2026.

"This committee recommendation is a historic step toward modernizing how Illinois courts treat companion animals during custody disputes," said Tameer Siddiqui, PsyD, lead policy architect of the Rosie's Law initiative. "The bipartisan vote in the House, combined with the Judiciary Committee's clearance, demonstrates that lawmakers across the state recognize the need for a legal framework that reflects how Illinoisans actually relate to their animals."

The bill is sponsored in the Senate by Sen. Linda Holmes and carried through the House by lead sponsor Rep. Barbara Hernandez, alongside a coalition of six House co-sponsors. For full legislative text and background materials, visit the Executive Summary and Full Bill Text pages on this hub.

What Is HB 4540, the Companion Animal Custody Equity Act?

HB 4540 is the Illinois bill that creates the Companion Animal Custody Equity Act, commonly referred to as Rosie's Law. It amends the Replevin Article of the Illinois Code of Civil Procedure to bring companion animals within the scope of judicial possession proceedings, meaning courts can evaluate who should have the animal using criteria specific to living beings, not inanimate objects.

Under current Illinois law, dogs, cats, and other pets are classified as personal property. In a dispute between two people over a companion animal, a court treats the animal the same way it would treat a piece of furniture: ownership documents typically govern the outcome, and the animal's welfare is legally irrelevant. HB 4540 changes that framework directly.

The bill defines "companion animal" broadly. It covers canines, felines, and equines, and extends to any animal the owner considers a pet. That scope is intentional; it avoids a narrow species list that would exclude animals many Illinoisans genuinely regard as family members.

By amending the Replevin Article rather than creating a standalone statute, HB 4540 integrates companion animal custody into the existing civil procedure structure Illinois courts already use. This is a deliberate legal architecture choice, not a symbolic gesture. It gives courts a recognized procedural vehicle for issuing possession orders and caregiving determinations.

Key Provisions: How Courts Will Evaluate Companion Animal Custody

HB 4540 gives Illinois courts structured criteria for evaluating companion animal possession disputes.

HB 4540 Illinois companion animal custody law does something no prior Illinois statute has done: it gives courts a structured set of criteria for deciding who gets the animal, rather than defaulting to whoever holds a receipt or adoption paperwork.

The bill identifies three core judicial considerations:

  1. Caregiving history. Courts may examine who actually fed, groomed, scheduled veterinary appointments, and provided day-to-day care for the animal. This shifts evidentiary weight toward documented, practical caregiving, not just legal ownership on paper.

  2. Emotional bond. Courts may evaluate the nature of the relationship between the companion animal and each party. This is not a vague sentiment; it is a recognizable legal inquiry, similar to how courts assess attachment in other possession contexts.

  3. Animal well-being and reduced stress. The animal's own condition and stability during proceedings becomes a legally relevant factor. Courts are explicitly authorized to issue temporary possession orders or limited visitation arrangements specifically to minimize disruption to the animal while the case is resolved.

Critically, these provisions apply regardless of marital status. The law covers divorcing spouses, but it equally applies to separated domestic partners, cohabitating roommates, and any two parties disputing possession of a companion animal. The bill does not require a divorce proceeding as the legal trigger.

Full Senate floor vote (Third Reading)

The 72-38 House vote is worth emphasizing. That margin is not a narrow partisan win; it reflects support drawn from across geographic and ideological lines, which matters when a Senate chamber evaluates whether a bill carries genuine statewide backing.

For readers unfamiliar with Illinois Senate procedure, Second Reading is the stage where the full chamber can consider amendments before a final vote. It is not a debate on passage; it is a structured opportunity to refine the bill's language. Once Second Reading concludes without further amendment, the bill moves to Third Reading, where senators cast their final votes.

HB 4540 is currently at the Second Reading stage, meaning it is positioned for floor action but has not yet been called for a final vote. Track live updates on the Bill Status page as the Senate calendar develops.

Sponsors and Legislative Champions Behind HB 4540

The sponsor coalition behind HB 4540 Illinois companion animal custody legislation is itself a signal worth reading carefully. Legislative tracker pages list names; they rarely explain what those names collectively represent.

On the House side, lead sponsor Rep. Barbara Hernandez carried the bill through passage with six co-sponsors: Rep. Dagmara Avelar, Rep. Justin Cochran, Rep. Edgar Gonzalez, Rep. Aaron Ortiz, Rep. Anne Stava-Murray, and Rep. Norma Hernandez. That coalition spans Chicago districts, suburban Cook County, and communities across northeastern Illinois, representing constituencies that are geographically distinct, demographically varied, and politically independent of one another. A bill that assembles that range of House authorship is not a narrow ideological project.

In the Senate, Sen. Linda Holmes serves as the bill's sponsor. Her office has framed the rationale in practical terms: Illinois courts currently lack statutory guidance when resolving companion animal possession disputes arising from domestic partnerships, and HB 4540 fills that gap directly.

The sponsor composition mirrors the actual diversity of Illinois pet owners who would be affected by this law, reinforcing that the bill's support reflects genuine constituent demand across the state.

Why the Senate Judiciary Committee Vote Matters for Illinois Animal Welfare Policy

The sponsor coalition's breadth makes the Senate Judiciary Committee's action all the more significant. That committee clearance is not procedural formality; in the Illinois Senate, bills referred to committee frequently die there. A Do Pass recommendation requires committee members to affirmatively conclude that a bill is legally coherent, constitutionally defensible, and ready for full chamber deliberation. HB 4540 cleared that threshold.

This distinguishes Rosie's Law from prior Illinois companion animal custody proposals that advanced no further than committee assignment. Earlier efforts to reform how Illinois courts handle pet possession disputes stalled precisely at this stage, often because sponsors lacked either the statutory architecture or the legislative coalition to move a bill forward. HB 4540 arrived at the Judiciary Committee with both: a legally grounded amendment to existing civil procedure and a 72-38 House vote behind it.

The national context reinforces why this moment matters. States including Alaska, California, and Illinois neighbors in the Midwest have progressively enacted companion animal custody frameworks. Illinois joining that group would represent a meaningful policy shift for a state with millions of pet-owning households.

Next Steps: What Happens Before HB 4540 Becomes Illinois Law

Passage of HB 4540 would protect the bonds between Illinois residents and their companion animals.

With the Senate Judiciary Committee clearance behind it, HB 4540 Illinois companion animal custody legislation now moves through three remaining procedural steps before it can become law.

Second Reading is the current stage. On the Senate floor, members may introduce amendments during this period. If no amendments are adopted, the bill advances without modification.

Third Reading follows, where senators cast their final votes. A simple majority is required for passage. Given the 72-38 House margin and the committee's affirmative recommendation, the bill enters floor consideration with demonstrated, cross-chamber support.

Governor's desk. A Senate-passed bill goes to the Governor for signature or veto. Signature enacts the Companion Animal Custody Equity Act into Illinois law.

The 104th General Assembly's spring session creates real deadline pressure; bills that do not reach a floor vote before adjournment must restart the process entirely in the next session.

Lawmakers, advocates, and organizational partners can monitor each remaining milestone on the Bill Status page, access structured media resources through the Media Kit, and review the policy foundation on the Executive Summary. This is the closest Illinois has come to giving companion animals a legally protected voice in custody proceedings, and the Rosie's Law initiative will continue providing accurate, current information until that protection is law.


The progression of HB 4540 through the Senate Judiciary Committee marks a significant shift in how Illinois courts view the well-being of companion animals. This legislation moves beyond traditional property laws to prioritize the actual needs of pets during legal disputes. Navigating these evolving statutes can be challenging; if you want expert help understanding the implications for your case, professional guidance is a natural next step. Seeking specialized support ensures your rights and your pet's interests remain protected throughout the legislative transition.
