What is a commitment ceremony?
A commitment ceremony is a formal but non-legally binding celebration in which two people (or, in some cases, more) publicly declare their commitment to one another. It is not registered with any government authority, and it does not create the legal relationship of marriage or civil partnership.
The ceremony itself can look almost identical to a wedding. There are often vows, an officiant, guests, and a reception. The key difference is what happens (or rather, what does not happen) on paper. No legal documents are signed, no registrar is present, and the relationship has no legal recognition under UK law.
What is involved in a commitment ceremony in the UK?
A commitment ceremony can be as simple or as elaborate as you choose. As there is no legal framework governing it, the structure is almost entirely up to you.
Vows
Most couples write their own, personalised vows. There is no prescribed wording, no legal language required, and no restrictions on what is said or promised.
Officiant
An officiant, often a celebrant, religious leader, or trusted friend, typically leads the ceremony. Unlike a legal wedding, the officiant does not need to be licensed or registered.
Venue
This is where commitment ceremonies stand apart from legal marriages most visibly. As no legal requirements apply, you are free to hold the ceremony anywhere: a beach, a garden, a restaurant, a forest, or anywhere else that feels right to you. There is no requirement to use a licensed venue.
Customisation
Readings, rituals, music, dress – everything is open to how you want it. For same-sex couples, polyamorous couples, or couples in non-traditional relationships who fall outside the scope of standard UK marriage law, this flexibility is especially significant. A commitment ceremony can include and honour relationship structures that the current legal system does not formally recognise.
How much does a commitment ceremony cost?
Costs vary depending on your choice of venue and who leads the ceremony. A ceremony run by an independent celebrant will often cost between £300 and £1,000 or more, while a simple non-legal ceremony held at a register office may cost between £200 and £500, though availability and pricing vary by location.
Due to there being no legal preliminaries or registrar certificates required, you also avoid the standard government marriage notice fees that apply to a legal wedding.
Commitment ceremony vs legal marriage vs renewal of vows: How do they differ?
Understanding how these three options compare can help clarify which one fits your situation.
| Feature | Commitment Ceremony | Legal Marriage or Civil Partnership | Renewal of Vows |
| Legal recognition | None | Yes, legally binding | None |
| Venue restrictions | None – any location | Must be a licensed venue (in England and Wales) | None |
| Officiant required | No legal requirement | Yes – a registrar or licensed religious official | No legal requirement |
| Financial/property rights | None created | Extensive rights including spousal maintenance, pension sharing, and property claims | No new rights created |
| Vows and ceremony style | Fully customisable | Prescribed legal wording required | Fully customisable |
Solicitor’s tip: A renewal of vows is intended for couples who are already legally married and wish to reaffirm their commitment – often at a milestone anniversary. It does not create a new legal marriage, it is simply a celebration of an existing one.
Why do couples choose a commitment ceremony?
People arrive at a commitment ceremony for very different reasons. It is rarely a default, instead, it is usually a deliberate, considered choice.
Rejecting the institution of marriage
Some couples feel that marriage, as a legal and cultural institution, does not reflect their values. For others, the historical association of marriage with patriarchal ideas makes it feel incompatible with the relationship they want to build as equals. A commitment ceremony offers a way to publicly celebrate that relationship on their own terms.
Keeping finances and assets separate
Legal marriage automatically links your financial lives in ways that may not be immediately obvious. Should the marriage end, the court has wide discretion to redistribute assets, income, and even pensions. Some couples (particularly those with significant assets from before the relationship, or those who have been through a costly divorce previously) specifically want to avoid that entanglement.
A commitment ceremony allows them to declare their commitment without altering their financial and legal status. The financial boundaries stay where they agreed them to be. This can be especially relevant for couples who are living together before marriage and want to understand exactly what that means legally.
Awaiting a divorce or consent order before remarrying
If one partner is still legally married to someone else, they cannot legally marry again – even if they have been separated for years. This would be viewed as bigamy under UK law. A final order must be in place before any new legal marriage can take place.
Similarly, a consent order resolving financial matters from a previous marriage is often advisable before entering a new one. For couples in this situation, a commitment ceremony provides a meaningful way to mark their relationship publicly while the legal process runs its course.
LGBTQ+ and non-traditional relationships
Same-sex couples in the UK have had access to civil partnership since 2004 and legal marriage since 2014. But not every LGBTQ+ couple wants either option, often for the same reasons some heterosexual couples also do not. Commitment ceremonies remain popular because they carry none of the historical weight of an institution that, for many years, excluded same-sex relationships entirely.
For polyamorous couples or those in other relationship structures that UK law does not formally recognise, a commitment ceremony may be the only available form of public celebration. It gives those relationships visibility and acknowledgement, even without a legal framework to support them.
Can a commitment ceremony be made legally binding?
A commitment ceremony cannot be made legally binding in England and Wales, regardless of how it is conducted or what language is used in the vows.
The only way to create a legally recognised relationship in the UK is through formal marriage or civil partnership, both of which require specific legal processes, a licensed official, and registration with the relevant authorities.
Some couples mistakenly believe that living together long enough creates a ‘common law marriage‘ that confers the same rights as legal marriage. This is a widely held myth, and a legally incorrect one.
Cohabitation in the UK does not create a common law marriage, regardless of how long the couple has been together or whether they have children.
Advice from one of our expert lawyers
Ciara Pugh, a Partner at our family law office in Hammersmith, says:
“Unfortunately, many people still believe that by virtue of living together, they are entitled to legal rights and protections if they separate or one party dies. It can then come as a real shock to couples to discover they are in a very vulnerable position with little recourse in terms of property, finances or inheritance.
“The ‘common law marriage’ myth is understandable, as Scotland used to have such a concept, and other jurisdictions recognise something similar. But unmarried couples need to understand their rights and put protections in place in case of a break-up or death of one person.”
What are the legal realities if we separate?
Cohabiting couples do not have the same legal rights as married couples. When a married couple separates, the family court can redistribute assets, make orders for spousal maintenance and share pension entitlements. Those powers do not apply where a couple has only had a commitment ceremony.
Property
If you own a home together, disputes are resolved not through family law but through trust and land law – specifically the Trusts of Land and Appointment of Trustees Act 1996 (TOLATA).
Under TOLATA, the court looks at each party’s legal and beneficial interest in the property, the original intentions behind the purchase, and the financial contributions each person made. These cases are complex, expensive, and often distressing. Without written evidence of what was agreed, the outcome can be deeply unfair.

Spousal maintenance
There is no right to claim ongoing financial support from a former partner after separation. The financial obligations that exist between married couples simply do not apply.
Pensions
Pension sharing – one of the most significant financial remedies available on divorce – is not available to unmarried couples. If one partner has a substantial pension built up over years of work, the other has no automatic claim to it.
How can you protect yourself legally?
The absence of legal protection does not mean you are without options. If you have had a commitment ceremony and live together, there are practical steps you can take – and two documents in particular are worth knowing about: A cohabitation agreement and a Declaration of Trust.
A cohabitation agreement is a formal document that sets out what you have agreed regarding property, finances, and other matters. While it is not automatically legally binding in the same way as a court order, a well-drafted agreement (prepared with proper legal advice) can carry significant weight if a dispute arises. It also provides clarity and reduces the scope for disagreement.
A Declaration of Trust is a different instrument, and in some respects a more powerful one. Unlike a cohabitation agreement, a Declaration of Trust registered with the Land Registry is legally binding. It records clearly how a property is owned, who holds what share, and how the proceeds should be divided if the property is sold or the relationship ends. If one partner paid a larger deposit, or has funded renovations, a Declaration of Trust protects that contribution.
If you’re wondering if you should have a cohabitation agreement or Declaration of Trust, know that the two documents can be used together – they are complementary, not alternatives.
Solicitor’s tip: The absence of legal protection does not mean you are without options, but those options need to be put in place before a separation happens – not after.
Knowing where you stand with our experts
If you have had a commitment ceremony and you share a home, finances, or other significant assets with your partner, getting clear on your legal position is genuinely important. The protection that legal marriage offers does not apply to you automatically, but with the right legal arrangements in place, you can create meaningful safeguards.
Our cohabitation specialists can help you understand what those arrangements look like for your specific situation.
