Create your draft on Wenup
Sign up and complete a guided questionnaire with your partner. We'll assign you a dedicated case manager to review your draft and make sure everything's in good order.
Connect with independent lawyers
When you're ready, we'll introduce each of you to separate, independent family lawyers who advise you on a fixed-fee basis. This is when the balance is paid, and you each receive your independent legal advice.
Online postnuptial agreements in the UK
Wenup is a fixed-fee, online way for UK couples to put a postnuptial agreement in place together. You both get independent legal advice, the price is fixed and transparent, and the whole thing is built to be fair to both of you, not adversarial.
How Much Does a Postnup Cost?
£690 per person
£1,380 total for the couple, all in.
- Wenup platform, case manager & drafting £780
- Independent lawyer, each partner £300 × 2
- Total, fixed £1,380
No hidden fees, no hourly billing
A traditional solicitor typically charges by the hour, and usually only advises one of you, so the real cost of getting both partners properly advised can run far higher and is hard to predict. With Wenup the price is fixed before you start, both of you are independently advised, and there is nothing more to pay.
How Easy Is It to Get a Postnup?
Easier than you would expect. There are no solicitor's offices, no chasing appointments and no open-ended fees. Most couples complete their questionnaire in an evening, have their lawyer calls within days, and sign shortly after.
What can a postnup protect?
A postnuptial agreement sets out how you would divide things if the marriage ever ended, so you can both feel secure. Couples commonly use one to protect:
Property
A home or assets owned before or during the marriage.
A business
A company or stake you have built up.
Inheritance
Family gifts or future inheritance.
Pensions & savings
Pensions, savings and investments.
We built Wenup to make the postnuptial agreement process fair, transparent, and affordable—for both of you.
Wenup
Independent legal advice for both sides
Each partner has their own solicitor or barrister, chosen from the same pool of experienced specialists, ensuring fairness and best practice under the Law Commission's guidance.
Specialists in nuptial agreements
Our entire platform is built for prenups and postnups - designed to meet the highest legal standards and to give you both peace of mind your agreement has a high likelihood of being upheld in court.
AI-powered drafting
We use technology and AI to prepare a professional first draft efficiently, saving time and cost before your lawyers review it.
Fair process by design
Both partners work on the same timeline, with equal access to time, lawyers, and review — ensuring transparency and balance.
3 years of free updates
Keep your agreement valid with 3 years of complimentary updates if you also complete your Will with Wenup.
Other Options
Only one side's lawyer quoted
Most online providers only quote for one person's advice - leaving the other to find and pay for their own lawyer separately. This will often cost more and can lead to an imbalance in the process.
Generalists
For most law firms and online legal services, nuptial agreements are a small, niche part of a much wider offering. However, nuptial agreements are unlike any other legal document. They require sensitivity, fairness and compliance with the Law Commission's guidance to have the optimal chance of being enforceable.
Manual drafting
Traditional law firms charge thousands just to draft the first version — even before advice begins.
Unbalanced process
One partner typically controls the timing, the lawyer, and the process — which can create inequality and tension.
Agreements lose weight
Without updates, an agreement can lose legal weight over time — but most providers don't offer a simple way to refresh it.
Are Postnuptial Agreements Legally Binding in the UK?
Postnups are not automatically binding in the UK, but the courts give them real weight, and will generally uphold one, when it has been entered into freely, with full financial disclosure and independent legal advice for both partners.
That is exactly how Wenup agreements are built. They are designed in line with the Law Commission's guidance, and because both of you are independently advised, your agreement is in the strongest position to stand up.
Is an online postnup valid?
Yes. What matters is not where it is created but whether it is done properly: full disclosure, fair terms, and separate legal advice for each of you. Wenup is built around those requirements from the start, which is why a downloaded template usually is not enough.
Wenup provides legal forms, information and access to independent lawyers. Wenup is not a law firm.
Proven Success
"We had a great experience using Wenup and are so happy we found this platform! James provided exceptional customer service from the initial consultation all the way through the signing of our document. We felt very supported during the process."
Laura
"The process was quick, smooth, and tailored around both our busy work lives, with an extremely high quality of service and James having always been available when needed- all of this for a fraction of the price you would normally expect. We cannot recommend Wenup highly enough, and would absolutely use it again (although hopefully won't have to 😉🤞🏼)"
Adam
"We cannot praise the whole team at Wenup enough! From the guidance during the initial steps to the fantastic lawyers who advised us individually, the whole process has been smooth, fast and transparent. And above all, the price was less than one third of all the quotes we had from some London law firms. Thank you!"
