If you and your partner are separating and you share a pet, one of the first painful questions is: who keeps the animal? It is a question that more and more couples are facing, and one that UK law is only beginning to catch up with.

This guide explains where things stand legally in 2026, what courts actually look at, and what you can do to reach a fair arrangement without needing a judge to decide for you.

The legal starting point: pets are still property

Under English and Welsh law, pets are classified as personal property; the same legal category as a piece of furniture or a car. This means that in a divorce, a pet is technically an asset to be divided, not a family member whose welfare drives the decision.

In practice, this has historically meant courts look at who paid for the animal: the purchase receipt, the microchip registration, the name on the insurance policy. Whoever has the paper trail has tended to keep the pet.

However, this is changing.

The 2024 shift: courts are now looking at caregiving

In December 2024, a significant ruling changed the conversation. In the case FI v DO, a judge stated plainly that it "matters not who paid for the dog" and placed weight instead on who had been the primary carer: who walked the dog, took it to the vet, and managed its daily routine.

This does not mean UK courts will now routinely make pet custody orders; they cannot. English and Welsh family law does not have a legal framework for shared pet custody the way some countries do. A judge can only award a pet to one party as an asset.

But what the ruling signals is that caregiving history is now a relevant factor. If you have been the one managing your pet's daily life, that matters, and documenting it matters.

Scotland is different

In Scotland, the legal position shifted more formally. The Animals (Scotland) Act and subsequent case law have moved Scottish courts further towards considering animal welfare as a factor in disputes. If you are based in Scotland, it is worth seeking advice specific to Scottish family law.

What courts look at in practice

If a pet dispute reaches a court in England or Wales, a judge will typically consider:

Who registered the microchip: Microchip registration is often treated as a strong indicator of ownership, even though it does not confer legal title. If your pet's microchip is registered in your name, that is a meaningful record.

Who paid for the animal initially. Purchase receipts, breeder invoices and adoption paperwork all carry weight.

Who has been the primary day-to-day carer. Vet records showing who brought the pet to appointments, evidence of who fed and walked the animal, and any documented caregiving history can all be relevant.

The welfare of the animal. Increasingly, judges are willing to consider which living arrangement would be better for the pet: the stability of the home, whether children are involved, whether the pet has a strong bond with one party.

What courts cannot do

A court cannot order a shared custody arrangement for a pet. If a dispute reaches a judge, they will award the animal to one person. There is no legal equivalent of a child arrangements order for pets in England and Wales; at least not yet.

This is exactly why reaching an agreement between yourselves, outside of court, is almost always in the best interests of everyone involved, including the animal.

What you can do instead of going to court

The most practical and least painful route is a written Pet Parenting Agreement, sometimes called a petnup. This is a document that sets out how you will both care for the pet going forward: who the primary carer will be, what the visiting arrangement looks like, how vet costs will be split, and how decisions about the animal's health will be made.

A Pet Parenting Agreement is not a legally binding court order. But it is a formal record of what you both agreed, signed by both parties, and it carries real weight if a dispute arises later. Courts can and do take such agreements into account.

Reaching this kind of arrangement is almost always quicker, cheaper and less damaging than a court process, and it produces an outcome that genuinely takes the pet's routine and wellbeing into account, rather than simply deciding ownership based on a receipt.

What about unmarried couples?

For couples who were not married, the position is in some ways clearer and in some ways harder. There is no divorce process, so there is no formal legal mechanism for dividing assets at all. Ownership falls back on who can demonstrate it: microchip, purchase paperwork, vet records in their name.

This makes proactive planning even more important for unmarried couples. A petnup agreed while the relationship is good is far easier to put in place than trying to resolve a dispute after it has broken down.

Practical steps to take now

• Check who the microchip is registered to. If it is not in your name and you are the primary carer, consider whether to update the registration: this is something to discuss openly with your partner rather than do unilaterally.

• Gather your caregiving records. Vet invoices, prescription records, grooming appointments; any paper trail that shows your involvement in the animal's care is worth keeping.

• Start a daily care log. Apps like Pawsettle allow you to record walks, feeds, vet visits and medication dates with timestamps. If a dispute ever arises, this kind of contemporaneous record carries significant weight.

• Talk to your partner before involving lawyers. A written agreement reached between the two of you will almost always produce a better outcome; for you, for them, and for your pet; than one imposed by a court.

The bottom line

UK law is moving in the right direction, slowly. Courts are beginning to look beyond purchase receipts towards caregiving and welfare. But the legal framework is not there yet to give pets the formal status many owners feel they deserve.

In the meantime, the most effective protection for you and your pet is documentation, an open conversation with your partner, and a written agreement that puts your pet's routine and wellbeing at its centre.
