The financial impact of UK divorce
Divorce triggers multiple tax + financial events:
- CGT spousal exemption ends after 3 tax years from separation
- Pension sharing or offsetting
- Property transfer or sale
- Child maintenance obligations
- Will + nomination updates
- Marriage Allowance cancellation
- IHT spouse exemption ends
The 3-year CGT window (most critical)
From 6 April 2023 (Schedule 1 Finance Act 2023):
- Spouses have 3 tax years from year of separation to transfer assets at no-gain-no-loss
- Previously limited to tax year of separation only
- If financial agreement signed during this period, transfers under Court Order or formal Agreement are no-gain-no-loss
- After 3 years, transfers become CGT-triggering disposals
Critical for high-value property + investment portfolios. Plan asset transfers within window.
Pension sharing on divorce
Pension Sharing Order (most common)
- Splits pension pot at "Decree Absolute" / Final Order
- Ex-spouse receives named % transferred to their own pension
- Pension shared is separate from inheriting spouse, cleanly broken
- Most common mechanism for substantial pensions
Offsetting
- One spouse keeps full pension, other takes more of non-pension assets (house, savings)
- Requires valuation of "pension benefit" at the time of separation
- Useful when one spouse needs cash now + other needs pension wealth
Child maintenance formula
| Children | % of gross paying parent income |
|---|---|
| 1 child | 12% |
| 2 children | 16% |
| 3+ children | 19% |
Reduced if paying parent has overnight shared care. £156k+ income: higher amounts may apply via court order.
Will + nomination updates (often forgotten)
- Will: Divorce revokes gifts to ex-spouse but not whole will - rewrite urgently
- Pension death nominations: Update to nominate children/family instead of ex-spouse
- Life insurance beneficiaries: Re-assign
- Joint bank accounts: Close + restructure
- Joint mortgages: Refinance to sole name
- Joint property ownership: Sever joint tenancy if planning differently

Frequently asked questions
How does the 2022 no-fault divorce reform work?
Divorce, Dissolution and Separation Act 2020 (effective April 2022) removed fault-based grounds. Either party can apply citing "irretrievable breakdown" - no need to allege adultery, behaviour, or separation period. Application → 20-week reflection period → conditional order → 6 weeks → final order. Total process minimum 26 weeks (6 months) - longer if finances unresolved.
When does Capital Gains Tax (CGT) spousal exemption end on divorce?
From 6 April 2023 (Schedule 1 FA 2023): spouses now have 3 tax years from year of separation to transfer assets at no-gain-no-loss (was previously only the tax year of separation). After 3 years, normal CGT applies on transfers. Critical for property + investment transfers - plan within window to avoid CGT triggers on splitting assets.
How are pensions split on divorce?
Three main mechanisms: (1) Pension Sharing Order - splits pension pot at decree absolute, ex-spouse gets named percentage transferred to their own pension; (2) Pension Attachment Order - ex-spouse receives % of pension payments when other spouse retires (less common, dies with original holder); (3) Offsetting - one spouse keeps full pension, other takes more of other assets (house, savings). PSO most common for substantial pensions.
How much does divorce cost financially in the UK?
Court fee £593 (2026/27). Solicitor fees: £1,000-£3,000 each for amicable, £5,000-£20,000 each for contested. Mediation: £200-£500 per session, typically 4-6 sessions. Total amicable: £3,000-£8,000 per couple. Contested with court hearings: £20,000-£100,000+. DIY divorce (no solicitor, just paying court fees): £593.
What is the standard financial settlement on UK divorce?
No formula - judges apply Section 25 Matrimonial Causes Act 1973 considerations: income + earning capacity, financial needs, contributions, age + duration of marriage, standard of living, conduct (rarely relevant). Long marriages (15+ years): typically 50/50 split of total assets unless special circumstances. Short marriages: often each keep what they brought. Children's needs take priority.
How is child maintenance calculated?
Child Maintenance Service formula: 12% of gross paying parent income for 1 child, 16% for 2, 19% for 3+. Reduced by number of "shared care" nights with paying parent (reductions kick in at 1+ nights/week). Adjusted for other children paying parent supports. Voluntary "Family-Based Arrangement" common alternative - more flexible but no enforcement.
What happens to Marriage Allowance on divorce?
Stops from the date of separation. The lower-earner partner must inform HMRC via Personal Tax Account or Marriage Allowance hotline. If not cancelled, HMRC will recover the £252/year benefit via PAYE adjustment retrospectively. Backdating: Marriage Allowance can be claimed for the 4 tax years before divorce if both qualified.
Do I need to update my will after divorce?
Yes urgently. Divorce automatically revokes any gifts to ex-spouse in will. If your will leaves everything to spouse + then doesn't name alternative, you die intestate (rules of intestacy apply). Pension nominations, life insurance beneficiaries, joint bank accounts - all need explicit review + update. Many people miss these and ex-spouse inherits unintentionally.
How does divorce affect mortgage + property?
Three options: (1) One spouse buys out other (typically requires remortgage), (2) Sell property + split proceeds, (3) Continue joint ownership with one living there until trigger event (children growing up). Each has tax + practical implications. Mesher Order: court order deferring sale until specific future event - common where children involved.
What about Inheritance Tax on divorce?
Spouse exemption ends from divorce date. Transfers between spouses during marriage IHT-exempt. After divorce: ex-spouses are not spouses for IHT - transfers may trigger IHT consequences. If divorce financial order requires ongoing maintenance + property transfers, structure carefully. Some property transfers in financial settlement are exempt under specific divorce provisions - take specialist advice.
