TL;DR
Family complications affecting UK money planning include divorce and remarriage, blended families with children from different relationships, cohabitation without marriage, step-parent inheritance issues, and elder care responsibilities. This guide explains the financial and legal frameworks that apply to each.
Key facts
- Cohabiting couples have no automatic property or inheritance rights from each other, regardless of how long they have lived together.
- Step-children have no automatic inheritance entitlement from a step-parent under UK intestacy rules.
- Pension sharing on divorce in the UK has been possible since 1 December 2000 under the Welfare Reform and Pensions Act 1999.
- The Inheritance (Provision for Family and Dependants) Act 1975 allows certain family members to claim against an estate that does not provide for them.
- The Children Act 1989 governs child arrangements in England and Wales, with separate frameworks in Scotland and Northern Ireland.
Modern UK families and money
UK families are increasingly varied: marriages, civil partnerships, cohabiting couples, second and third marriages with children from previous relationships, single-parent households, intergenerational caring arrangements, and cross-border families. Each pattern interacts with money, tax, and inheritance rules differently. This guide sets out the main complications and the framework that applies to each.
The cohabitation gap
Cohabiting couples have no automatic legal rights to each other's property or estate, however long they have lived together. The 'common law marriage' is a myth in UK law. On separation, each partner keeps what is in their sole name unless they can establish a beneficial interest through trust law. On death, the surviving partner has no automatic inheritance under intestacy rules; only a claim under the Inheritance (Provision for Family and Dependants) Act 1975 may be available.
Second marriages and remarriage
Remarriage automatically revokes any existing will unless the will was made in contemplation of the new marriage. Without a new will, the new spouse takes priority under intestacy rules, often at the expense of children from a previous relationship. Pre-nuptial agreements are increasingly used in second marriages to protect assets brought into the new relationship, though they are not strictly binding in English courts under current law.
Blended families
Blended families face specific issues around inheritance, financial provision for step-children, and pension nominations. Step-children have no automatic inheritance from a step-parent. A new will, life cover with named beneficiaries, and pension expression of wishes forms are the standard tools to ensure assets pass in the intended direction.
Divorce and pension sharing
Pensions are a significant asset in many divorces. Three options exist: pension sharing orders (creating a separate pension for the receiving spouse), pension attachment (the saver retains the pension but the ex-spouse receives a defined share at retirement), and pension offsetting (the pension is balanced against other assets). Each has different tax and timing consequences.
Step-parent inheritance
Where a step-parent dies intestate, step-children have no entitlement under the standard intestacy rules. A claim under the 1975 Act may be available if the step-child was financially dependent on the deceased. The standard route to give a step-child equivalent treatment is by will.
Children from multiple relationships
Where a parent has children with multiple partners, the standard intestacy rules treat all biological and adopted children equally. Step-children require provision by will. Many parents in this situation use trusts (life interest trusts, discretionary trusts) to balance current spouse and previous children.
Elder care responsibilities
Caring for ageing parents often falls on adult children. UK law does not impose a statutory duty on adult children to fund their parents' care. Means-tested local authority care funding considers the parent's capital and income, not the children's. Power of Attorney arrangements made before capacity is lost simplify decision-making later.
The 1975 Act safety net
The Inheritance (Provision for Family and Dependants) Act 1975 allows certain categories of person (spouse, ex-spouse who has not remarried, child, step-child, person treated as a child of the family, cohabitant for at least 2 years) to claim reasonable financial provision from an estate. Claims must be made within 6 months of the grant of probate or letters of administration.
The role of advance planning
Most family complications can be mitigated by clear planning: an up-to-date will, pension nominations, life cover, Power of Attorney, and (where significant assets are involved) trust structures. The cost of advance planning is small compared with the cost of contested probate, divorce litigation, or care funding disputes.
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.
