Can I get my dog or cat back if there was no written agreement?

Yes, in many cases. Pet custody disputes are rarely decided by a single document. Courts examine patterns of care over time — who fed and walked the pet daily, who paid vet bills, who handled licensing. The absence of a written agreement does not mean you have no rights. It means the facts need to be assembled carefully.

What if the pet is registered or microchipped in the other person's name?

Registration and microchip records are relevant, but not determinative. Courts routinely consider them alongside the full picture of ownership and care. In many cases, those records were created for convenience — not as a reflection of actual responsibility. We know how to contextualize them.

Does it matter who paid for vet bills, food, or training?

Yes. Financial responsibility is often among the most persuasive indicators of ownership. Veterinary records, receipts, and documented ongoing care can significantly strengthen your position. Gathering this documentation early matters.

Will a court consider what's best for the pet?

Increasingly, yes. Following our recent Appeals Court ruling in the Dobby case, Massachusetts courts in cases involving joint ownership and a severed relationship may be asked to weigh the best interests of the animal. This is a developing area of law — one we are actively shaping. The arguments need to be framed carefully and backed by facts. We know how to present them.

What if our informal custody arrangement stopped working?

This is one of the most common scenarios we see. When one party stops honoring a shared arrangement — formal or informal — legal intervention is often the only way to protect your access. Early action prevents the situation from hardening into something harder to reverse.

How quickly should I act if someone refuses to return my pet?

Immediately. Extended possession by the other party can shift the legal dynamics of your case. Delay rarely helps and often hurts. If someone is refusing to return your pet, contact us before taking other steps — the early decisions matter.

Massachusetts Pet Custody Law Is Changing — Boston Dog Lawyers Is Leading That Change

jeremy-cohen-boston-dog-lawyers-teddy-bear-pomeranian.jpg .jpg

Jeremy Cohen, founder of Boston Dog Lawyers, with Teddy Bear the Pomeranian—the dog at the center of Lyman v. Lanser, the 2024 landmark case that established precedent for pet custody rights in Massachusetts.

A Single Justice of the Massachusetts Appeals Court then reviewed the matter and made a pivotal observation: in pet custody cases with similar fact patterns of joint ownership and a severed relationship, courts should consider the best interests of the dog.

The Justice's words speak for themselves:

"Dobby is not a jointly-owned baseball card collection... Dobby was intended, as pet dogs ought to be, to be part of the family."

Dobby was reunited with his owner after a Massachusetts Appeals Court ruling recognized pets as family members and called for courts to consider the best interests of dogs in custody disputes.

This is not a statewide statutory overhaul. But it is the next step up the legal staircase that began with Lyman — and it signals a judicial willingness to treat companion animals as more than objects to be divided. We are not just practitioners in Massachusetts pet custody law.

We are shaping it.

Massachusetts moved one step closer to recognizing what so many pet owners have always known: our pets are family.

That shift is not hypothetical.

In Lyman v. Lanser — our 2024 landmark case centered on Teddy Bear the Pomeranian — Massachusetts courts established that pets can be treated as unique property and that courts can enforce pet-sharing agreements between unmarried co-owners. It was a foundational step.

Then came Dobby.

Our client spent four years separated from her dog after her former partner refused to continue sharing him.

After two prior attempts in court with previous counsel, Boston Dog Lawyers filed in Massachusetts Superior Court and secured a preliminary injunction affirming her equal possession rights.

Who We Serve

Pet custody disputes arise in more situations than most people realize:

A former partner refusing to return a pet after a breakup or separation
A family member claiming ownership of a pet they had limited involvement in caring for
A friend or roommate withholding a pet after a falling out
An informal shared custody arrangement that has collapsed
A rescue organization or breeder disputing an adoption or return

In most cases, there was no written agreement — or the one that existed is no longer being honored. That does not leave you without options.

What's At Stake?

The legal risk in pet custody cases is not abstract. Under Massachusetts law, pets are classified as personal property. That framework creates specific vulnerabilities:

Delay works against you. Extended possession by the other party can shift the legal footing of a case.
Informal arrangements offer limited protection. Even acknowledged agreements can fail to hold up when circumstances change.
Loss of access can become permanent if a case is not handled strategically from the beginning.

The emotional cost is real. The legal risk is real. Both are avoidable with early action.

GOING TO COURT

Can Pet Custody Cases Be Resolved Without Court?

Often, yes — and when it can be, that outcome is usually faster, less costly, and less damaging to everyone involved.

We evaluate every case for early resolution. In appropriate situations, we assist with:

Negotiating custody or possession terms
Drafting binding agreements that define rights and responsibilities clearly
Structuring arrangements that hold up if the relationship deteriorates further

But early resolution requires the other party to engage in good faith. When they won't — or when the situation is already adversarial — litigation becomes necessary. We are prepared for both.

What Happens If the Case Goes to Court?

Pet custody cases are highly fact-specific. Courts working within a property framework often lack the context to identify which facts matter most. That is where strategic advocacy makes the difference.

The questions a court will weigh include:

When did the pet effectively become yours?
Who provided primary day-to-day care?
Who paid for veterinary care, food, licensing, and training?
Where has the pet lived, and what does each party's current situation look like?

Following the Dobby ruling, courts in cases involving joint ownership and a severed relationship may now be asked to consider the best interests of the animal. We know how to argue within that framework — because we built it.

Why These Cases Are Different

There is no single formula for winning a pet custody case. There are dozens of legal arguments and hundreds of indicators of ownership, care, and responsibility — and the other side will try to control which ones the court focuses on.

Experience in these cases is not incidental. It is the difference between a court that sees the full picture and one that defaults to whoever has physical possession or a name on a microchip record.

How Boston Dog Lawyers Handles These Cases

We assess whether your situation is legally actionable and advise you on risk, cost, and realistic outcomes — honestly.

When action is warranted, we move quickly. We identify the strongest indicators of ownership, build your factual record, and advocate with the credibility and preparation these cases require.

We have recovered pets for clients who were told they would never see their animal again. That outcome is not guaranteed — but it is not uncommon either.

OUR EXPERIENCE — YOUR EDGE

Not Sure If You Have a Case?

Many people contact us uncertain whether their situation qualifies. That uncertainty is understandable — and answerable.

If you are in a dispute over a pet and don't know what your options are, contact us at 844-364-2889. We will help you evaluate your position and decide on next steps.

FAQs — Pet Custody & Ownership Disputes in Massachusetts

Yes. In 2024, Boston Dog Lawyers established precedent in Lyman v. Lanser, which recognized pets as unique property and affirmed that Massachusetts courts can enforce pet-sharing agreements between unmarried co-owners. More recently, a Single Justice of the Massachusetts Appeals Court ruled in one of our cases that courts should consider the best interests of the dog in pet custody disputes involving joint ownership. Massachusetts has not adopted a child-custody framework for pets, but these rulings mark a significant and ongoing shift in how courts approach these cases.
