Jersey legal advice for Relationship Agreements
In Jersey, unmarried couples do not enjoy the same legal protections as those who are married or in a civil partnership. Regardless of how long a couple has lived together, cohabiting partners have no automatic rights to property, inheritance, or financial support. This lack of legal recognition can lead to significant uncertainty and risk, particularly when relationships break down or one partner passes away. A relationship agreement offers a practical and proactive way to formalise arrangements and safeguard each partner’s interests.
A relationship agreement is a legally binding contract between two individuals who live together or share financial responsibilities. It sets out how assets are owned, how expenses are shared, and what will happen if the relationship ends. These agreements are especially useful where one partner owns property, holds housing qualifications, or has substantial financial resources. By clearly defining each party’s rights and obligations, a relationship agreement can help prevent misunderstandings and disputes.
In Jersey, one of the most common sources of conflict between unmarried partners is property ownership. The person named on the title deeds is generally considered the legal owner, even if the other partner has contributed financially to the purchase or upkeep of the property. Without a formal agreement, the contributing partner may have no legal claim. A relationship agreement can clarify each party’s interest in the property, reducing the risk of litigation and ensuring that contributions are recognised.
Relationship agreements can be tailored to reflect the unique circumstances of each couple. Common areas covered include:
- Contributions to mortgage or rent payments
- Sharing of household expenses and savings
- Ownership of personal and joint assets
- Financial support during the relationship and in the event of separation
- Arrangements for children, including residence, contact, and financial provision

At Parslows LLP, our family law team regularly advises cohabiting couples on how to protect their interests. We take the time to understand your situation and can if required draft bespoke documents that reflect your lifestyle, priorities, and future plans. Each agreement is supported by independent legal advice to ensure fairness and legal validity.
In addition to relationship agreements, we also advise on wills and inheritance planning. If one partner dies without a will, the surviving partner may have no entitlement to the estate, regardless of the length or nature of the relationship. This can be particularly distressing and financially damaging. A relationship agreement, combined with a properly drafted will, can ensure that your wishes are respected and that your partner is protected.
Our approach is both practical and sensitive. We understand that every relationship is different, and that discussing legal arrangements can feel daunting. Our team is here to guide you through the process with clarity and compassion, helping you make informed decisions that offer peace of mind.
Whether you are moving in together, purchasing property, starting a family, or planning for the future, a relationship agreement can provide a solid foundation for your shared life. It is not just about preparing for the worst, it is about creating certainty and mutual understanding.
