National Pet Day: Why pet owners should think about a pet‑nup

As the UK celebrates National Pet Day this month, it’s the perfect moment to celebrate the animals who brighten our lives – and to think practically about their wellbeing should life take an unexpected turn.

The UK remains a nation of pet lovers, and the numbers speak for themselves. According to the PDSA Animal Wellbeing Mini Report 2025, around half of UK adults now own a pet. With animals so deeply embedded in family life, it’s no surprise that disputes over who keeps the family pet are becoming increasingly common when couples separate. Previous reports suggest that tens of thousands of divorce cases involve pets each year, often adding significant emotional strain at an already difficult time. As pet ownership continues to grow, interest is rising in a practical solution designed to prevent conflict: the pet‑nup.

What are pet-nups and how can they help?

Unlike arrangements for children, UK courts currently have no formal legal framework for deciding who keeps a pet after a breakup. Pets are still treated as property in the eyes of the law, even though most owners see them as family members. This mismatch often leads to painful disputes, prolonged negotiations, and, in some cases, costly legal battles.

A pet-nup, a pet specific prenuptial or cohabitation agreement, sets out what will happen to your pet if you and your partner separate. It can be included within a wider pre-nup before marriage or created as a standalone agreement at any stage of your relationship, including when you first bring your pet home.

A well drafted pet-nup can:

• clarify ownership
• reduce conflict
• protect your pet’s welfare.

What to consider when getting a pet-nup

Before drafting a pet-nup, it’s worth discussing a few key points:

1. Ownership and evidence

• Who purchased or adopted the pet?
• Whose name appears on microchip registration, insurance, or vet records?

2. Financial responsibilities

• How will you divide ongoing costs such as food, insurance, grooming, and veterinary bills?
• Who will cover unexpected expenses?

3. Living arrangements

• Where will the pet live day to day?
• Will the other partner have visiting rights or shared care?
• What happens if one person relocates?

4. Your pet’s best interests

Every pet has unique needs. Consider factors such as routine, attachment, exercise requirements, and temperament when deciding what arrangement would genuinely support their wellbeing.

Why a pet-nup matters

A pet-nup offers peace of mind. It ensures that, even if your relationship changes, your pet’s life remains stable and secure. It also helps avoid emotionally charged disputes at a time when both partners may already be under strain.

As we celebrate National Pet Day, it’s a reminder that loving our pets isn’t just about treats and cuddles, it’s also about planning for their future. A pet-nup is one thoughtful way to do just that.
