The Williams v Williams case is a fascinating example of how courts distinguish between joint tenancy and tenancy in common, particularly when dealing with family-owned properties that serve both as homes and as businesses. At the centre of this dispute was Cefn Coed Farm, acquired by the Williams family in 1986 and run as a joint business, with family members working together in a farming partnership. The question before the court was whether this property should be regarded as a joint tenancy or a tenancy in common—a determination with significant implications for inheritance and ownership rights.

Joint Tenancy vs. Tenancy in Common: What’s the Difference?

In a joint tenancy, each co-owner has an equal share in the property, and ownership automatically passes to the surviving co-owner(s) upon death (right of survivorship). In contrast, with a tenancy in common, each co-owner can hold different percentages of ownership, and their share does not automatically pass to the others; instead, it becomes part of their estate, allowing it to be inherited separately.

In Williams v Williams, Dorian Williams argued that the farm was intended as a joint tenancy, suggesting that upon the death of one partner, the entirety should pass to the surviving co-owner(s). However, the court ultimately found that Cefn Coed was held as a tenancy in common due to the farm’s mixed personal and business use, along with the lack of an express declaration of joint tenancy.

The Role of Business Dynamics

The court placed significant weight on the fact that the farm was a business as well as a family residence. Farms and other family businesses are typically treated as tenancies in common because business assets usually aren’t suited to automatic transfer through survivorship. This is to ensure each party's financial interest can be inherited or sold independently, respecting the distinct contributions and intentions of each co-owner. The farming partnership highlighted the family’s intent for each person’s interest in the farm to be separable, which pointed away from joint tenancy.

Legal Principles and Presumptions

Several cases, including Stack v. Dowden, have shaped how the courts approach co-owned property, typically favouring tenancy in common for commercial assets, even those with a personal component. In Williams v Williams, this presumption held, with the Court of Appeal concluding that business assets carry an implicit assumption of tenancy in common unless stated otherwise.

Implications for Practitioners

For family law and property practitioners, Williams v Williams reinforces the importance of clear declarations regarding ownership structures, especially for family-owned business assets. When a property is used for both family and commercial purposes, courts are likely to favour tenancy in common to ensure clarity in ownership rights, prevent automatic transfer through survivorship, and allow for a fair distribution of financial interests.

This case emphasises the significance of clarifying ownership intent at the outset, particularly for family businesses or mixed-use properties, to prevent future disputes over ownership rights.
