As more couples choose to put a prenuptial agreement in place before getting married, many are looking for ways to do so that feel clear, affordable and straightforward. Alongside traditional family-law firms, a growing number of fixed-fee and online prenup platforms are now available in the UK.
This guide focuses specifically on fixed-fee and online prenup platforms, how they work, and what couples should consider before choosing one.
If you're still deciding whether a prenuptial agreement is right for you, our guide to prenups in the UK explains how they work and when couples typically choose to use one.
What is a fixed-fee prenup platform?
A fixed-fee prenup platform is a UK-based service that offers a prenuptial agreement for a set price, rather than charging by the hour. These platforms usually combine online questionnaires or tools with solicitor involvement, helping couples outline their finances, intentions and future plans before a formal legal document is drafted.
The aim is to make the process more predictable in terms of cost and timelines, and often more structured for couples who want clarity from the outset.
How do fixed-fee prenup platforms usually work?
While each provider has its own approach, many fixed-fee prenup services follow a similar structure:
- Both partners provide financial information and details about assets, income and expectations
- A draft prenuptial agreement is prepared based on this information
- Each partner receives legal advice on the agreement before signing
- The agreement is finalised and signed well in advance of the wedding
Some platforms focus heavily on online tools and coordination, while others operate more like a traditional law firm with digital elements layered on top.
Key things couples should check before using a fixed-fee platform
Because prenuptial agreements must meet certain standards to be taken seriously by the courts in England and Wales, it's important to look beyond the headline price.
Independent legal advice
It is generally accepted that both partners should receive independent legal advice. This means each person has their own solicitor explaining the agreement to them and confirming they understand it and are entering into it freely. Couples should check whether a quoted fee includes legal advice for both parties, or only one.
What the fixed fee actually covers
Some advertised prices cover drafting only, while others include legal review and advice. If one partner's legal advice is not included, additional costs may need to be factored in.
Timing and flexibility
Prenups should be signed well before the wedding. Couples may want to understand how long the process usually takes and whether revisions are possible if circumstances change.
Collaborative vs one-sided processes
Some services are designed for couples to work through the agreement together from the outset, while others follow a more traditional model where one person instructs a lawyer and the other reviews the document later. Either approach can work, but it's helpful to understand which model a service uses.
Future updates
Major life changes, such as having children, receiving an inheritance or buying property, can affect whether a prenup remains fair and relevant. Some services offer updates or reviews, while others charge separately.
Examples of fixed-fee prenup providers in the UK
Couples exploring fixed-fee prenuptial agreements in the UK may come across a range of online platforms and law firms offering these services. These services vary in how they combine technology, solicitor involvement and ongoing support, so it's worth reviewing what each one includes.

Final thoughts
Fixed-fee prenup platforms can offer a more transparent and predictable way to put a prenuptial agreement in place, particularly for couples who value cost certainty and structure. However, the details matter.
Before committing, couples should take the time to understand what is included in the fee, ensure both partners receive independent legal advice, and feel comfortable with how the process works. A prenup is ultimately about clarity and fairness for both people, and choosing a service that supports that aim is key.
