A prenup is much simpler when you tackle it in the right order. Skip a step – usually disclosure, advice or timing – and that is exactly where agreements run into trouble later. Here is a practical, step-by-step checklist for engaged couples in England & Wales. Work through it from the top and the whole thing stays calm, fair and robust.
The prenup checklist, step by step
- Start early. Begin the conversation months before the wedding, not weeks – see when to sign a prenup and how long it takes.
- Talk openly about money. Agree what you each want to protect and what feels fair. If you are unsure a prenup is right for you, see do you need a prenup? and how to talk about a prenup.
- Gather full financial disclosure. Both partners list assets, property, savings, pensions, business interests, income and debts in a full and frank disclosure (see the information you need).
- Decide the terms. How separate and joint property are treated, and what happens on divorce or death – our guide to what to include covers this.
- Prepare the agreement. Online for a fixed fee, or via a solicitor (see online vs solicitor).
- Take independent legal advice. Each partner, ideally their own solicitor (see why advice matters).
- Check it is fair. It should provide for both partners and any children – not leave anyone in need.
- Sign it correctly. As a deed, with an independent witness, at least 28 days before the wedding (see how to sign a prenup).
- Store it safely. Keep the signed original with the disclosure schedule and advice letters (see storing your prenup).
- Diarise a review. Revisit it after major life changes, ideally via a built-in review clause.

The steps couples most often skip
If a prenup is going to be challenged, it is usually because one of three steps was rushed or missed: honest disclosure, independent advice, or leaving enough time before the wedding. Treat those three as non-negotiable and you remove the most common reasons an agreement is set aside (see can a prenup be overturned?).
Keep it calm and collaborative
The healthiest prenups are made together, early, as a joint plan – not sprung on one partner at the last minute (see a fair prenup for both partners). Approached this way, the process itself can strengthen a relationship rather than strain it. For the full walkthrough, see our step-by-step guide to getting a prenup.
A worked timeline for the checklist
To see how the steps fit together, imagine a wedding six months away. Months five and six are for the conversation: agreeing you both want a prenup and roughly what it should protect. Month four is disclosure – each partner pulling together assets, pensions, income and debts, and requesting any statements that take time to arrive. Month three is for settling the terms and preparing the agreement. Month two is independent legal advice for each partner, with appointments booked early. That leaves the agreement ready to sign roughly six weeks out – well clear of the 28-day mark – with the final weeks reserved for storing it safely and getting on with the wedding. Nothing here is rushed, and every step has room to breathe. If you have less than six months, compress the early stages rather than the advice and signing (see how long a prenup takes).
How the checklist keeps a prenup robust
Each item on the list maps onto something a court looks at when deciding how much weight to give an agreement. Full disclosure shows both partners knew what they were agreeing to. Independent advice shows each understood the implications and was not pressured. Fair terms that meet both partners’ and any children’s needs keep the agreement from being set aside as unjust. Signing as a deed, in good time, closes off arguments about formality and pressure. No prenup is automatically binding in England & Wales, but since Radmacher v Granatino (2010) a court will give real weight to one made this way. In other words, the checklist is not busywork – it is a plain-English version of the safeguards that make an agreement stand up (see are prenups legally binding?).
Emotional and practical preparation
The checklist covers the mechanics, but two softer things make the whole process easier. The first is framing: approach a prenup as a joint plan for fairness and clarity, not as one partner protecting themselves against the other. Couples who discuss it openly and early tend to find the conversation brings them closer rather than driving a wedge (see how to talk about a prenup and is a prenup unromantic?). The second is realism about what a prenup does: it sets out what you have agreed and gives a court a strong steer, but it cannot oust the court’s discretion or override the welfare of children. Going in with accurate expectations means neither partner feels misled about what they are signing (see common prenup myths).
Adapting the checklist to your situation
The core steps are the same for everyone, but the emphasis shifts with your circumstances. If one partner owns a home the other will move into, spend extra care on how that property is treated and whether contributions during the marriage change things (see when one partner owns the home). If either of you runs a business, factor in a rough valuation and think about how future growth is handled (see prenups for business owners). In a second marriage or blended family, protecting children from a previous relationship usually moves up the list, and the prenup should sit alongside up-to-date wills. Where one partner earns or owns far more than the other, fairness and honest disclosure carry even more weight, because a lopsided agreement is the kind most likely to be challenged (see prenups and income disparity). Run through the same checklist either way – just give more time to the steps that carry the most weight for you.
Why this prenup checklist works
The point of a prenup checklist is order: do the steps in sequence and the whole thing stays calm and fair. Start early, talk openly, disclose fully, agree fair terms, take independent advice, sign as a deed in good time, store it safely, and diarise a review. Skip a step – usually disclosure, advice or timing – and that is exactly where agreements run into trouble later.
The law behind the order of the steps
The checklist runs in this order because each step is the evidence for the one after. The conversation and the disclosure come first because the second limb of the test in Radmacher v Granatino is that each party entered the agreement with a full appreciation of its implications, and nobody can appreciate what they are giving up without knowing what the other has. The Law Commission's 2014 report set the standard at disclosure of material information about each other's finances rather than a valuation of everything, which is why rough, dated figures are enough and a hidden asset is not.
The advice step follows the drafting step because advice is about the finished terms. The Supreme Court treated independent legal advice as one of the main indicators that a party understood the agreement, and the Law Commission would make it a formal requirement of a qualifying nuptial agreement. The fairness check comes next because section 25 of the Matrimonial Causes Act 1973 requires the court to meet each partner's reasonable needs, with first consideration to any child under eighteen, and section 34 makes void any term that tries to stop either of you applying to the court.
Signing has two rules of its own. Section 1 of the Law of Property (Miscellaneous Provisions) Act 1989 requires each signature on a deed to be made in the presence of a witness who attests it. And the Law Commission's 28-day guideline coincides with section 31 of the Marriage Act 1949, which requires 28 days' notice before a civil ceremony, so signing on the day you give notice satisfies both. The review step exists because fairness is judged in the circumstances prevailing at the divorce, not at the wedding.
Prenup checklist: FAQs
What do you need to start a prenup?
Both partners’ financial details and your wedding date (see what information you need).
What is the most important step on the checklist?
Full, honest disclosure from both partners – without it, an agreement can be set aside (see hidden assets and prenups).
How early should engaged couples start?
Ideally a few months before the wedding, to clear the 28-day signing mark comfortably (see how long does a prenup take?).
Do we both need our own solicitor?
Ideally yes, so the advice is independent (see do both partners need a lawyer?).
What if we have almost no time left?
Consider a postnup after the wedding rather than rushing (see last-minute prenup).
Is there a financial checklist too?
Yes – see our financial checklist for engaged couples for the money side of getting married.
Does following the checklist make our prenup binding?
No prenup is automatically binding in England & Wales, but following the checklist ticks the safeguards that make a court give it significant weight under Radmacher v Granatino (2010) (see what makes a prenup invalid).
Can we use the checklist for a postnup too?
Largely yes – disclosure, fair terms, independent advice and correct signing apply equally to a postnup; only the wedding timing drops away.
Who should raise the prenup first?
Either partner – what matters is raising it early and kindly, as a shared plan rather than an ultimatum (see whose idea should a prenup be?).
