Cohabitation Reform: A Fairer End to Relationships or a New Era of Litigation?

Introduction

For years, cohabitation has been one of the most problematic areas of family law in England and Wales. Despite more than 3.5 million couples now choosing to live together without marrying or entering a civil partnership, the law has remained rooted in property and trust principles rather than reflecting the realities of modern family life.   The result is a legal landscape that is often confusing for separating couples, expensive to navigate and challenging even for experienced lawyers. Cohabitation disputes frequently require family lawyers to venture into the territory of civil litigation, trust law and equitable principles in order to resolve issues arising from the breakdown of what was, in every practical sense, a family relationship.   However, significant reform may finally be on the horizon.   Whether those reforms ultimately become law remains to be seen. The proposals still need to get over the legislative finish line. Nevertheless, they represent the most substantial attempt in decades to address the shortcomings of the current system.   Until then, cohabiting couples should consider entering into a Cohabitation Agreement, which will provide certainty in the event of separation.  

Why Reform is Being Considered  

The objectives behind the proposed reforms are relatively straightforward: Prioritising the welfare of children Protecting financially vulnerable parties Creating a clear and accessible legal framework Preserving the distinct legal status of marriage   At present, none of those objectives are straightforwardly achieved by the existing law.   The current framework often leaves vulnerable cohabitants without effective remedies while forcing disputes into expensive litigation concerning beneficial ownership, common intention and financial contributions. At the same time, many separating couples are shocked to discover that the concept of a "common law marriage" simply does not exist.   The proposed reforms seek to address those concerns while maintaining a distinction between marriage and cohabitation.  

A Significant Shift Towards the Family Courts  

One of the most notable consequences of reform could be a substantial shift of cohabitation disputes away from the civil courts and into the family justice system.   Currently, many claims are pursued under the Trusts of Land and Appointment of Trustees Act 1996 (TOLATA), requiring courts to determine beneficial ownership of property. The focus is often on historic financial contributions and inferred intentions rather than the broader circumstances of the relationship. If there are minor children of the family, the dispute becomes even more complex, with the potential introduction of a claim under what is known as Schedule 1 of the Children Act 1989.   The proposed reforms would move much of that analysis into a needs-based framework, which is similar to matrimonial principles on divorce.   However, this does not necessarily eliminate disputes. Questions concerning ownership and contributions are likely still to arise. The difference may simply be that they are determined within a cohabitation claim rather than through standalone TOLATA proceedings.  

The Proposed Opt-Out System  

The reforms propose an opt-out model applying to qualifying cohabiting couples.   To opt out, parties would be required to satisfy stringent safeguards, including: A formally valid agreement Execution by deed Signed statements acknowledging the consequences Financial disclosure Independent legal advice   At first glance, these protections appear sensible. However, they raise a practical question: how many couples will actually seek to obtain one?   The reality is that many people who choose not to marry are unlikely to incur legal fees to enter into a formal cohabitation agreement. Even where agreements are made, relationships evolve. Properties are purchased, children are born, careers change and inheritances are received.   Full financial disclosure and independent legal advice may be entirely appropriate, but they also increase costs and reduce accessibility.  

What is an "Enduring Family Relationship"?  

A central issue will be determining who qualifies for protection.   The proposed reforms will look at whether there has been an enduring family relationship and to determine that, the court will look at various factors, including: The existence of a joint household The stability of the relationship Financial arrangements and financial ‘behaviour’ within that relationship Whether there are any children of the family Whether there is an intimate relationship The extent to which the relationship is publicly recognised   However, not every relationship will neatly satisfy those criteria.   For example, many elderly couples may deliberately maintain separate finances whilst sharing their lives together. Others may not have children or may spend periods living apart due to employment or caring responsibilities.   Determining whether a relationship qualifies may therefore become a significant point of litigation in its own right.  

Duration Requirements and Vulnerable Cohabitants  

The proposals suggest no minimum duration requirement where the parties have  children. Otherwise, a minimum cohabitation period of three years has been suggested. Whether this ends up in the final document remains to be seen.   The parties to that cohabitation are expected to be at least 18 years of age. This may leave certain vulnerable individuals without protection. Consider a 17-year-old parent living with an older partner in circumstances that resemble family life. Such individuals may fall outside the cohabitation regime entirely and be forced to rely on alternative remedies, including claims under the Children Act 1989.   The interaction with inheritance law may also prove problematic, particularly where different qualification periods apply between cohabitation claims and succession claims.  

Limitation Periods: Simplicity or Further Complexity?  

The proposed limitation period of two years from separation appears attractive in principle. However, when does a cohabiting relationship actually end? A lot of my clients think that because they continue living under the same roof, they are not separated, when they may in fact be. This in itself could be an area of contention in litigation.   Many separating couples continue living under the same roof due to financial pressures or childcare arrangements. Others separate gradually rather than through a single identifiable event.   Without judicial discretion to extend time limits, genuine uncertainty may arise regarding whether claims have been issued in time.   What appears straightforward on paper may prove considerably more difficult in practice.  

A Different Regime from Marriage  

The reforms expressly reject the sharing principle that applies in matrimonial finance cases.   This means cohabitation claims would not begin from a presumption of equal sharing, as in the context of a divorce.   Instead, the starting position would remain that each party retains what they own, with any departure from that position being driven by needs rather than sharing.   This distinction is intended to preserve the special legal status of marriage.   Yet the practical effect is that beneficial ownership disputes are unlikely to disappear entirely. Courts may still need to determine what each party owns before considering whether additional provision is required to meet needs.  

A Needs-Based Framework  

The proposed remedies closely resemble those available in financial remedy proceedings following divorce.   Potential orders may include: Capital provision Lump sum payments Property adjustment Pension provision and pension sharing Income-based orders in limited circumstances   The needs of any minor child would take priority over the needs of adults.   The assessment of needs is expected to draw heavily upon factors familiar to practitioners under section 25 of the Matrimonial Causes Act 1973. One of the greatest challenges will be defining needs. Basic housing and living expenses are relatively straightforward. Discretionary needs are not.   Are private school fees a necessity or a lifestyle choice? What about country club memberships, private healthcare or second homes? The answer may differ dramatically depending upon the circumstances of the parties. A lifestyle regarded as ordinary in Mayfair may appear entirely different in Sheffield.   Compensation may also play a role. For example, where one party has sacrificed their career to care for children, the court may be able to take that into account. However, this is a rare and difficult concept to prove even in the simplest divorce case.   Misconduct remains an area of significant debate. Given the growing recognition of domestic abuse within family proceedings, there is a strong possibility that any future regime will reflect developments already seen within financial remedy litigation.  

The Pursuit of a Clean Break  

The proposals favour achieving a clean break wherever possible. Ongoing maintenance would be reserved for exceptional circumstances, such as serious illness or disability. If we draw a distinction here between cohabitation and matrimonial law, at present, there is no ongoing maintenance claim in a cohabitation dispute. In matrimonial proceedings, the court will consider an income claim, however, it will ultimately seek to achieve a clean break if possible.   While attractive in principle, this approach may create difficulties in practice. Many separating couples have significant income disparities but limited capital assets. In such cases, an outcome without some continuing income provision may feel unfair.  

Preserving the Status of Marriage  

The reforms repeatedly emphasise the need to preserve marriage as a distinct legal institution. Indeed, there is an express suggestion that cohabitants should not receive awards exceeding those available to a married couple.   Yet there is an argument that this protection is largely unnecessary. If cohabitants are already excluded from the sharing principle and restricted to a needs-based approach, the legal framework is already materially less generous than the matrimonial regime.   The distinction may therefore be preserved without additional statutory safeguards.  

Reform Beyond Separation: Cohabitation and Succession  

The proposals extend beyond relationship breakdown and into inheritance law.   Perhaps the most controversial suggestion is that qualifying cohabitants would inherit under the intestacy rules in broadly the same way as spouses. This raises an obvious question. If the objective is to preserve the special status of marriage, can spouse-equivalent inheritance rights truly be reconciled with that objective?   The proposals also provide that where a deceased person remains married to someone else, the cohabitant would not qualify for intestacy rights.   In addition, for claims under the Inheritance (Provision for Family and Dependants) Act 1975, the existing two-year cohabitation requirement would be removed where the parties share a child.   These changes would significantly strengthen the position of surviving cohabitants.   However, they also raise a broader policy question: should a cohabitant who survives the deceased alongside surviving children enjoy the same intestacy rights as a spouse? That debate is likely to continue long after any legislation is enacted.  

The Practical Reality  

The proposed reforms undoubtedly seek to create a fairer, more coherent and more straightforward framework for cohabiting couples. They attempt to balance protection for vulnerable individuals against the desire to preserve marriage as a distinct legal institution.   Whether they succeed in doing so remains open to debate, but in my humble opinion, anything will be better than the existing framework.   What is clear is that cohabitation disputes are unlikely to disappear. Questions surrounding qualification, needs, ownership, limitation periods and succession rights will continue to generate litigation, albeit in a different form.   For practitioners, the battleground may shift from trust law to family law. For separating couples, uncertainty may be reduced but not eliminated.  

Conclusion: the one step every cohabiting couple should take  

Regardless of whether these reforms become law, one message remains unchanged: every cohabiting couple should seriously consider entering into a cohabitation agreement either at the start of their cohabitation or during.   A carefully drafted agreement can record property ownership arrangements, financial responsibilities, intentions regarding property and expectations in the event of separation. Most importantly, it can provide certainty at a time when relationships are strong rather than leaving difficult questions to be answered years later by a Judge in a courtroom.   Whatever the future holds for cohabitation reform, prevention will always be preferable to litigation. A cohabitation agreement remains one of the most effective ways of avoiding the lengthy, complex and expensive disputes that so often arise when cohabiting relationships come to an end.
