TL;DR
A second marriage in the UK has specific financial and legal implications: existing wills are revoked, pension and life cover nominations need updating, prenups are increasingly used to ring-fence pre-marriage assets, and inheritance planning must consider children from previous relationships. This checklist outlines the key items.
Key facts
- Marriage automatically revokes any existing will unless the will was made in contemplation of the new marriage.
- Prenuptial agreements are not strictly binding in English courts but courts give them significant weight if entered into freely with disclosure and legal advice (Radmacher v Granatino, 2010).
- Pension expression of wishes forms are not legally binding but are normally followed by trustees.
- Life interest trusts in a will can give the second spouse a right to live in the family home while preserving the capital for children of a previous relationship.
- Joint tenancy of a home passes automatically to the surviving co-owner outside the will; tenancy in common allows each owner's share to pass by will.
Why second marriages need a different financial plan
A second marriage introduces obligations to a new spouse alongside existing obligations to children from a previous relationship. The default UK legal rules can produce outcomes that neither party intends: a new spouse can inherit much or all of an estate at the expense of biological children, or vice versa. Specific planning steps prevent these outcomes.
Update or replace the will
Marriage automatically revokes any existing will unless the will was made specifically in contemplation of the new marriage. Without a fresh will, intestacy rules apply: the new spouse takes a statutory share that can leave children from a previous relationship with substantially less than the testator intended.
Consider a life interest trust
A life interest trust in a will allows the new spouse to live in the family home or receive income from invested assets during their lifetime, with the capital reverting to children from a previous relationship on the spouse's death. This is a common structure where the testator wants to provide for the spouse without disinheriting children.
Property ownership: joint tenancy vs tenancy in common
Joint tenancy means the property passes automatically to the surviving co-owner, outside the will. Tenancy in common means each owner has a defined share that passes under their will. Severing a joint tenancy converts it to tenancy in common and is a common step where a second marriage and children from a previous relationship are involved.
Pension and life cover nominations
Pensions are typically not part of the estate and pass according to the scheme's discretion, guided by the member's expression of wishes form. Life cover written in trust similarly passes outside the estate. Both should be reviewed and updated on remarriage.
Prenuptial agreement
Prenups are not strictly binding in English courts but have been given significant weight by the Supreme Court (Radmacher v Granatino, 2010). To carry weight, the prenup must be entered into freely with full disclosure on both sides, with independent legal advice, and at least 28 days before the wedding. Scotland has different rules and is more accepting of prenups.
Inheritance tax considerations
The IHT nil-rate band of GBP 325,000 is transferable between spouses. The residence nil-rate band of up to GBP 175,000 is also transferable but is only available when a main home passes to direct descendants (children, step-children, foster children, adopted children, or further descent). Step-children qualify but more remote relatives generally do not.
Power of attorney
Lasting Powers of Attorney for property and financial affairs and for health and welfare allow the chosen attorney to make decisions if the donor loses capacity. Without LPAs, an application to the Court of Protection is needed, which is slower and more expensive.
The Matrimonial Causes Act 1973 framework
Financial provision on UK divorce is governed by the Matrimonial Causes Act 1973, particularly sections 23, 24, and 25. Section 23 gives the court power to make periodical payments orders (maintenance), lump sum orders, and pension orders. Section 24 gives the court power to make property adjustment orders, including transfer and settlement of property and variation of nuptial settlements. Section 25 sets out the factors the court must consider in exercising these powers.
The section 25 factors include: income, earning capacity, and other financial resources of each party; financial needs, obligations, and responsibilities; standard of living during the marriage; age of parties and duration of the marriage; physical or mental disability; contributions to the welfare of the family (financial and non-financial); conduct (where it would be inequitable to disregard it); and the value of any benefit which a party will lose the chance of acquiring.
The case law has refined the application of section 25 over decades. White v White (House of Lords, 2000) established the yardstick of equality between the earning and homemaker spouses. Miller; McFarlane (House of Lords, 2006) refined the analysis into three strands: needs, sharing, and compensation. Subsequent cases have applied these principles to different fact patterns including short marriages, pre-marital assets, and high-net-worth disputes.
The Form E disclosure process and FDR
Where financial settlement is contested, the procedural framework starts with the Mediation Information and Assessment Meeting (MIAM) before any court application can be made (subject to limited exceptions). The court application is made on Form A, followed by exchange of Form E financial disclosure. Form E requires comprehensive disclosure of capital, income, pensions, business interests, and outgoings.
The First Directions Appointment (FDA) gives directions on questionnaires, valuations, and disclosure. The Financial Dispute Resolution (FDR) hearing follows, with the judge giving a non-binding indication of the likely outcome. Many cases settle at or before FDR; FDR is structured specifically to encourage settlement. Where the case does not settle, it proceeds to a final hearing for a binding determination.
Most settlements are reached by agreement and formalised in a consent order submitted to the court for approval. The court reviews the order to ensure the terms are reasonable in the parties' circumstances. Consent orders are typically approved without a hearing. Once made, the order is binding and enforceable, with limited grounds for variation or appeal.
Pension sharing, attachment, and offsetting
Pension sharing orders under the Welfare Reform and Pensions Act 1999 have been available since 1 December 2000. A pension sharing order specifies the percentage of the cash equivalent transfer value (CETV) to be transferred from one spouse to a separate pension for the other. The receiving spouse becomes the owner of the transferred share, with full control independent of the original saver.
Pension attachment (formerly earmarking) leaves the pension with the saver but directs a percentage of the lump sum or income at retirement to the ex-spouse. Pension offsetting balances the pension value against other matrimonial assets, leaving the pension with the original holder in exchange for the other spouse receiving more of the other assets (such as the family home).
For defined benefit pensions, the CETV is calculated by the scheme actuary using assumptions about future investment returns, longevity, and inflation. CETVs vary substantially with gilt yields. A pension actuary is often appointed in higher-value cases to produce a 'fair value' estimate that adjusts for the inflation-linked income that the CETV may not fully reflect.
No-fault divorce under the 2020 Act
The Divorce, Dissolution and Separation Act 2020 introduced no-fault divorce in England and Wales from 6 April 2022. The Act replaced the previous five facts (adultery, behaviour, desertion, two years separation with consent, five years separation) with a single statement of irretrievable breakdown. The respondent cannot contest the factual basis of the divorce; only jurisdiction, fraud, and procedural validity remain available grounds for challenge.
The minimum timeline from application to final order is 26 weeks: a 20 week reflection period before the conditional order, then 6 weeks before the final order. Joint applications by both spouses are now possible alongside sole applications. The terminology was updated: petitioner became applicant, decree nisi became conditional order, decree absolute became final order.
Scotland operates a different regime under the Divorce (Scotland) Act 1976 as amended. Northern Ireland operates under its own legislation. The no-fault reform applies only in England and Wales.
Cross-border family elements
The 1980 Hague Convention on the Civil Aspects of International Child Abduction provides for the prompt return of children wrongfully removed across borders. Applications are made through the Central Authority of either country; in the UK this is the International Child Abduction and Contact Unit (ICACU) within the Ministry of Justice. The Convention requires expeditious court action with a target of 6 weeks from application to decision.
The 1996 Hague Convention on Parental Responsibility coordinates jurisdiction and recognition of orders across contracting states. The 2007 Hague Maintenance Convention provides for cross-border enforcement of maintenance orders. Brussels IIa, which previously coordinated EU member states, ceased to apply to the UK from 1 January 2021; the EU-UK Trade and Cooperation Agreement and the Hague Conventions now provide the framework.
Child Arrangements Orders and the Children Act 1989
Where parents cannot agree on arrangements for their children after separation, an application can be made for a Child Arrangements Order under section 8 of the Children Act 1989. The order can specify with whom a child is to live (the 'live with' element) and what time the child spends with each parent (the 'spend time with' element). The court applies the welfare paramountcy principle: the child's welfare is the court's paramount consideration.
The court process begins with a Mediation Information and Assessment Meeting (MIAM) before any application can be issued. The application uses Form C100. Cafcass (the Children and Family Court Advisory and Support Service) is involved in disputed cases, undertaking safeguarding checks and producing welfare reports for the court.
Child maintenance is administered separately through the Child Maintenance Service or by family-based arrangement. The CMS uses a formula based on the paying parent's gross income (12 percent for one child, 16 percent for two, 19 percent for three or more, on income up to GBP 800 per week, with adjustments for shared care nights).
Domestic abuse and protective orders
The Domestic Abuse Act 2021 introduced a statutory definition of domestic abuse and established the Domestic Abuse Commissioner. The Act expanded the available protective orders, including the new Domestic Abuse Protection Notice (DAPN) and Domestic Abuse Protection Order (DAPO). Non-molestation orders and occupation orders under the Family Law Act 1996 continue to operate.
Legal aid is available for domestic abuse victims for both immigration and family law matters under specific provisions. The National Domestic Abuse Helpline at nationaldahelpline.org.uk provides 24/7 support. Citizens Advice, Refuge, Women's Aid, and other specialist organisations provide practical and emotional support alongside the legal framework.
Costs and legal aid in family proceedings
Average UK contested divorce financial proceedings costs have been reported by the Family Justice Council as running from low five-figure sums to six figures in complex cases. Each party generally pays their own legal costs; the court can order otherwise where one party's conduct has caused unnecessary cost. Legal aid for private family law matters is heavily restricted under the Legal Aid, Sentencing and Punishment of Offenders Act 2012, with limited availability for domestic abuse victims and children-related matters.
Mediation is encouraged by the Civil Procedure Rules and the Family Procedure Rules. Successful mediation can dramatically reduce costs and reach durable outcomes. Family mediators accredited by the Family Mediation Council operate under specific professional standards. MIAM attendance is compulsory before issuing most family law applications.
