How much does a prenup cost in the UK? It varies enormously depending on how you have it prepared and how complex your finances are, from a fixed £750 online, with a solicitor's advice included, to four figures with a solicitor drafting from scratch. Below is a realistic, up-to-date picture of prenuptial agreement costs in England & Wales, what sits behind each price, and how to spend sensibly without cutting the corners that actually matter.
In short: From £750 for an online prenup with independent advice for one of you, or £1,300 with a solicitor for each of you. Solicitor drafting runs to four figures per side, and more where there are trusts or a business. The court looks at how the agreement was made, not what it cost.

Each figure was read from that provider's own page, all checked on 26 October 2026. Where a firm quotes "+ VAT", add 20% to compare it with a price that includes VAT, as ours does. Providers change their prices and what those prices cover, so treat the date as part of the figure.
What UK Prenup's price includes
- One of you advised
- £750
- Your agreement, prepared online from your answers; forms to list what you each own and owe; a private page where your partner reviews and confirms it; and an independent family-law solicitor's meeting, written advice letter and signed certificate for one of you.
- Both of you advised
- £1,300
- The same, with a solicitor for each of you, from different firms: two meetings, two advice letters and two certificates.
What the extra £550 buys
Your partner's own independent advice, from a solicitor at a different firm, arranged through UK Prenup and paid for in the package. Advice on both sides is one of the things a court weighs when deciding how much weight to give a prenup. At £750, your partner takes their own advice from a firm of their choosing and pays that firm (firms' own price guides put it at £550–£1,750 + VAT per person), or confirms they have chosen not to.
What isn't included
- Changes after advice aren't included. If you change the agreement after your solicitor has advised, they advise you again for £180 including VAT (£150 plus VAT), paid to them directly.
- At £750, your partner's own advice, as above.

Solicitor-drafted prenups
Having a prenup drafted by a family-law solicitor traditionally costs four figures once everything is included, and that is usually per side rather than for the couple. A typical engagement involves the solicitor taking instructions, drafting the agreement, negotiating between the two partners' solicitors, and providing separate independent legal advice for each person. Fees rise with the complexity of the assets involved: businesses, trusts, overseas property and pensions all add time, and every round of negotiation adds more. For genuinely complex estates this is money well spent; for straightforward finances it can be far more than the job requires. See how much solicitors charge for a prenup, and how the online and solicitor routes compare.
Online prenuptial agreements
Online services have made prenups far more accessible. With UK Prenup, couples in England & Wales can create their agreement online for a fixed £750, including an independent family-law solicitor's advice for one of you, or £1,300 with a solicitor for each of you, from different firms. You answer guided questions about both partners' finances and wishes, property, savings, pensions, businesses, debts and how you want assets treated, and your draft is ready as soon as you finish, for the solicitor to advise on before you sign.
The fixed fee is the whole cost of the document; there is no hourly billing and no surprise at the end. For couples with clear finances, this is often all they need; for those who want a lawyer's eyes on it, it is an inexpensive foundation to take to advice.
Wondering whether it is worth it? For most couples a prenup is far cheaper than a contested divorce. Just be wary of a bargain-basement prenup, a DIY template, or a "poor man's prenup" that cuts the corners, disclosure, fair terms, correct signing, that make an agreement hold up.
The best-value approach for most couples
You do not have to choose between "cheap and risky" and "expensive and thorough". Many couples get the best of both by preparing the agreement online and having an independent solicitor advise on the finished document. At UK Prenup that is £750 with advice for one of you, or £1,300 with a solicitor for each of you. Because the drafting is already done, the solicitor's job is to advise rather than build from scratch, which costs a fraction of a full bespoke engagement while still ticking the independent-advice box that makes an agreement more robust. It keeps the total well below a traditional two-solicitor process without sacrificing the safeguards that matter.
What affects the price?
- Complexity: straightforward finances cost less than businesses, trusts, pensions or overseas assets.
- Negotiation, back-and-forth between solicitors is where traditional fees climb; an agreement you broadly agree in advance costs less to finalise.
- Independent legal advice, sensible for both partners, and usually charged separately per person (see do both need a lawyer?).
- How you draft it: a fixed-fee online document removes the open-ended hourly billing that makes solicitor costs hard to predict.
Should you still take legal advice?
Yes. Whichever route you choose, independent legal advice for each partner is one of the factors that makes a prenup more likely to be upheld (see are prenups legally binding? and independent legal advice for a prenup). An online service keeps the drafting cost low; you can then have each partner review the finished agreement with a solicitor for far less than a full bespoke drafting engagement.
What you are paying for, in legal terms
The price of a prenup is easier to judge once you know what the law asks of it. Under the test in Radmacher v Granatino a court gives effect to an agreement that was freely entered into by each party with a full appreciation of its implications. The exception is where it would be unfair to hold the parties to it. Everything on a solicitor's bill maps onto that test. Drafting produces terms that are fair and complete.
Financial disclosure, the exchange of a schedule of each partner's assets, income and debts, is what shows each of you knew what you were agreeing to. The Law Commission's recommended standard is disclosure of material information rather than a valuation of every possession, so it costs time rather than money. Independent legal advice for each partner is the evidence that each understood the document, and it is the single item most worth paying for.
Execution as a deed, signed in the presence of a witness under section 1 of the Law of Property (Miscellaneous Provisions) Act 1989, costs nothing but has to be done correctly.
Negotiation is where solicitor-led costs run away. Two firms exchanging drafts over an inheritance clause can add more to the bill than everything else combined, and none of that exchange improves the agreement's legal standing; it only changes its terms. Couples who agree the substance between themselves first, then have the document prepared and each take advice on it, keep the enforceable parts and cut the expensive part.
Is a cheap prenup enforceable?
Price is not a factor a court considers. What it considers is whether the safeguards were there: disclosure, advice, timing and fairness. A £750 agreement made with all four is in a stronger position than a £3,000 one signed the week before the wedding without disclosure, because the court's test looks at how the agreement was made, not what it cost. Two things no fee can buy, at any price, are worth knowing.
Section 34 of the Matrimonial Causes Act 1973 makes void any term that tries to stop either spouse applying to the court, so no prenup is "100% binding" whatever a seller claims. Section 25 keeps the court's discretion to meet each partner's reasonable needs and, first, the welfare of any child under eighteen. A fair agreement leaves room for both, and is usually followed as a result.

Prenup cost FAQs
How much does a prenup cost in the UK on average?
There is no single figure: an online agreement with a solicitor's advice included is £750 at UK Prenup (£1,300 with a solicitor for each of you), while solicitor-led agreements usually run into four figures per side once both partners take advice.
Why are solicitor prenups so much more expensive?
They are usually billed by the hour and involve drafting, negotiation between two firms and separate advice for each partner (see solicitor prenup costs).
Is a prenup cheaper than a divorce?
Almost always. A contested divorce can cost many thousands of pounds in legal fees alone (see is a prenup cheaper than a divorce? and the cost of divorce in the UK).
Is a cheap or DIY prenup worth it?
Be careful: a bargain-basement or DIY prenup that skips disclosure or fair terms can be worse than none at all.
Does a prenup cost the same as a postnup?
Broadly yes. A postnup costs much the same: a fixed fee online with a solicitor's advice included, or four figures via a solicitor.
Are there any ongoing costs after signing?
No. A prenup is a one-off cost. You may choose to update it later (for example under a review clause), but there is no annual fee.
Does the price include VAT?
Not always. Many solicitors quote before VAT, so add 20% to compare them with a price that includes it, as UK Prenup's fixed fee does.
Is legal advice included in the price?
It depends on the provider: some prices cover drafting only, some one partner's advice, and a few both of you. Compare what each price covers, not just the figure; the table above sets that out for each provider.
Who pays for a prenup?
Either of you, or both: the law says nothing about it. Each partner's own legal advice is usually paid for separately, unless a package covers both of you.
Does a prenup cost more in London?
Usually, if a solicitor drafts it: the court's guideline hourly rates for solicitors are highest in London, and many solicitor prenups are billed by the hour. A fixed-fee online service costs the same wherever you live in England & Wales.
Create your prenuptial agreement online
UK Prenup lets couples in England & Wales create a prenuptial agreement online, with an independent family-law solicitor's advice before you sign: £750 for one of you, or £1,300 with a solicitor for each of you. See how it works or get started.
