How to Prove You Are the Primary Carer for a Pet in the UK
Published 25 March 2026
April 2026
Following the landmark Fi v Do ruling in December 2024, caregiving history has become one of the most relevant factors in pet disputes in England and Wales. If you have been the one managing your pet's daily life, that now carries real weight.
But weight in a dispute only comes from evidence. Saying you were the primary carer is not enough. Being able to show it is what matters.
Why caregiving evidence matters now
The Fi v Do ruling shifted the conversation in English and Welsh courts from a purely transactional question: who has the receipt, to a more nuanced one: who has actually been there for this animal day after day?
District Judge Crisp, presiding over the case, ruled that financial ownership alone should not determine the outcome. Instead, she considered who had been the primary carer, the nature of each party's bond with the animal, and the pet's relationship with children in the household. The decision placed ongoing caregiving above financial ownership as the primary consideration.
This is a meaningful change. It means that if you have been walking the dog every morning, attending every vet appointment and managing the medication schedule, your position in a dispute is stronger than it would have been before December 2024. But only if you can demonstrate it.
It is worth noting that Fi v Do applies in England and Wales only. Scotland, Australia, Canada and the United States each have their own legal frameworks for resolving pet disputes, and the weight given to caregiving evidence varies by jurisdiction. That said, the broader direction of travel is consistent: courts in multiple countries are increasingly looking at who has cared for an animal, not just who paid for it.
What counts as caregiving evidence
Evidence of primary caregiving falls into two categories: historical records that already exist, and contemporaneous records you create going forward.
Historical records
These are documents created in the normal course of caring for your pet, not specifically for the purpose of a dispute. They tend to carry more weight precisely because they were not created strategically.
Vet records are the strongest single source. Every appointment, vaccination, prescription and procedure generates a record. If your name appears on those records as the person who brought the animal in, that is significant. Contact your vet and ask for a full history of appointments.
Prescription and medication records. If your pet takes regular medication, whoever collects prescriptions and purchases medication is creating a paper trail.
Pet insurance records. Who took out the policy, who pays the premiums and whose contact details are on the account all reflect sustained involvement in the animal's care.
Grooming, training and boarding records. If you have used a groomer, a trainer or a boarding facility, those businesses will have records of who booked appointments and who dropped the animal off.
Online shopping history. Food, toys, bedding, leads, supplements. Your purchase history from any retailer shows sustained financial and practical involvement in the animal's care.
Banking records. Direct debits for insurance, regular purchases at pet shops, vet payments. A bank statement showing consistent spending on a pet over months or years is meaningful evidence of caregiving.
Photos and videos. A timestamped camera roll showing you with the animal over an extended period, at home and out on walks, is simple but useful supporting evidence.
Social media. Posts, check-ins and tagged photos showing your relationship with the animal over time create an informal but readable record of your involvement.
Contemporaneous records
If your situation is uncertain or a dispute is already developing, start keeping a daily care log immediately. Do not wait.
A care log is a dated, timestamped record of every caregiving activity: walks, feeds, vet visits, medication, grooming, training sessions and any other relevant interaction. The value of a care log is that it is contemporaneous: created at the time rather than reconstructed afterwards. This distinction matters. Courts and mediators treat records made in the moment very differently from accounts put together after a dispute has arisen.
Pawsettle's Caregiver Log is designed specifically for this purpose. It timestamps each entry automatically and can generate a formatted PDF report covering any date range you choose. That report is exactly the kind of document that carries weight in mediation or legal proceedings.
What to do about the microchip
Microchip registration is often treated as one of the strongest indicators of ownership, even though it does not legally confer title. If your pet's microchip is registered in your partner's name and you are the primary carer, this is worth addressing carefully.
Our guide to whether a microchip proves ownership explains the legal distinction in detail. If the registration does not reflect the reality of who cares for the animal, updating it is something to do openly and with your partner's agreement, not unilaterally.
If there is already a dispute, do not attempt to change the registration without your partner's knowledge. This will look like you are acting in bad faith and is likely to count against you.
What if you have no records at all
Some people find themselves in a dispute without any formal documentation. This is not the end of the road, but it does mean you need to work harder.
Start with your vet. Even if the account is not in your name, the practice staff may remember you as the person who routinely attended appointments. A letter or statement from a vet confirming your regular involvement is meaningful evidence.
Talk to people who know your relationship with the pet. Dog walkers, neighbours, friends and family members who have seen you care for the animal over time can all provide written statements confirming your involvement.
Start a Caregiver Log now. Even if you cannot reconstruct the past, a consistent record from today onwards demonstrates your ongoing commitment to the animal's care.
What to avoid
Do not delete messages or alter documents. Do not prevent your partner from seeing the pet while a dispute is ongoing unless there is a genuine welfare concern. Do not make claims you cannot support with evidence. Do not wait: start your log today. Do not change the microchip registration unilaterally if a dispute is already in progress.
Getting a written agreement in place
The strongest position combines evidence of caregiving with a written agreement that both parties have signed. A Pet Parenting Agreement documents what has been decided about the pet's care going forward and provides a reference point that is difficult to dispute later.
If you are not yet in a dispute but want to protect your position, a Petnup created now, while things are calm, is the most straightforward way to ensure your caregiving role is formally recognised before any disagreement arises.
The bottom line
The law has shifted. Caregiving now matters in pet disputes in a way it did not five years ago. But caregiving without evidence is just a claim. Evidence without caregiving is just paperwork.
The strongest position is one where the documents reflect the reality: you have been there, day after day, looking after this animal. If that is true, the job now is to make sure it is provable.
