Getting married is one of the biggest financial life events you’ll experience — not just the wedding cost, but the long-term financial relationship that follows. There’s also a surprising amount of admin to sort.
Here’s the complete financial checklist for UK couples getting married in 2026.
Before the Wedding
1. Talk Money — Seriously
Before you marry, have honest conversations about:
- Individual income, debts, assets
- Attitude to risk and spending
- Savings goals
- Financial commitments (student loans, child maintenance, etc.)
Money disagreements are one of the leading causes of relationship breakdown. Starting with transparency makes everything easier.
2. Understand Your Individual Starting Positions
| Item | Partner 1 | Partner 2 |
|---|---|---|
| Annual income | ||
| Outstanding debts | ||
| Savings | ||
| Pension value | ||
| Credit score |
Debt you bring into a marriage remains individual liability — unless you take on joint credit products. Your partner’s debts don’t automatically become yours.
After the Wedding
3. Apply for Marriage Allowance
What it is: Transfer up to £1,260 of unused Personal Allowance from the lower-earning partner to the higher earner.
Who qualifies:
- One partner earns below £12,570/year (the Personal Allowance threshold)
- The other partner earns between £12,570–£50,270 (basic rate taxpayer)
Annual saving: Up to £252/year.
Backdating: You can backdate 4 years — potentially worth £1,008 in total.
How to apply: Online at gov.uk/marriage-allowance. Takes minutes.
4. Check and Update Your Tax Code
After marriage, your tax code may change (particularly if claiming Marriage Allowance). Check via your Personal Tax Account at HMRC or your payslip.
5. Update Your Will — Urgently
In England and Wales: Marriage automatically revokes any previous will. If you had a will before the wedding, it is now invalid. Without a new will, intestacy rules apply on death — which may not reflect your wishes.
Action: Make new wills for both partners within weeks of marrying. A basic will costs £150–£300 through a solicitor; services like Farewill or Wills Online offer simpler options from £90.
What to include:
- Who inherits your assets
- Who is executor of your estate
- Guardianship of children (if you have or plan to have them)
- Any specific bequests
6. Update All Pension Nominations
Pension funds are not distributed via your will — they’re controlled by a separate Expression of Wishes or nomination form held by your pension provider.
Action: Contact every pension provider and update your nomination to include your spouse. This is critical — and easy to forget.
Types of pension to update:
- All current employer workplace pensions
- All previous employer pensions (track them down — there are 3.3 million lost pensions in the UK)
- Personal pensions and SIPPs
- Any inherited pension funds
7. Update Life Insurance Nominations and Beneficiaries
If you have life insurance policies, update the beneficiary to your spouse. Group life insurance through your employer should be updated via HR.
8. Review Existing Insurance
After marriage:
- Home and contents: If moving in together or changing property, update or combine policies
- Life insurance: May want to increase cover if combining finances and/or starting a family
- Income protection: More important when someone else depends on your income
- Joint health insurance: Often cheaper per person than individual policies
9. Decide on Your Bank Account Approach
Common models:
| Model | How it works | Best for |
|---|---|---|
| Fully joint | One account, all income in | Simple, fully merged approach |
| Joint + individual | Shared account for bills + own accounts | Couples wanting autonomy |
| Three-account system | Two personal accounts + one joint | Most flexible for mixed incomes |
A joint account does not protect you automatically — both account holders can withdraw everything, and joint overdrafts are joint liability.
10. Update “Next of Kin” Records
Update next of kin designations at:
- Your employer (HR records)
- Your GP/NHS records
- Your pension providers
- Your bank accounts
- Your employer’s life insurance scheme
Financial Planning Together
11. Establish Shared Financial Goals
| Goal | Target amount | Target date | Monthly saving needed |
|---|---|---|---|
| Emergency fund (3–6 months expenses) | |||
| House deposit (if not yet bought) | |||
| Holiday/experience fund | |||
| Pension contributions |
12. Are Your Pensions on Track?
Marriage often prompts a first serious pension review. Run the numbers:
- What combined pension income are you on track for at state pension age?
- Does either partner have a pension gap (career breaks, self-employment, under-contribution)?
- Should you increase contributions now — especially with employer matching?
The earlier you act, the cheaper it is to fix gaps. See our pension planning guides.
13. Protection Insurance: What You Actually Need
Now that someone depends on your income:
| Type | Purpose | Who needs it |
|---|---|---|
| Life insurance (term) | Replaces income if you die | Both partners if combined finances |
| Income protection | Replaces income if you can’t work | Both partners, especially higher earner |
| Critical illness | Lump sum on serious illness | Worth considering for mortgage holders |
| Buildings & contents | Protects your home | Essential |
14. Name Change Admin (If Applicable)
If either partner is changing their surname:
Update with:
- Passport (cost: ~£88.50)
- Driving licence (free online)
- HMRC (Personal Tax Account)
- Employer (payroll, HR)
- Bank accounts
- Student Loan Company
- Electoral Roll
- Pension providers
- National Insurance records
- Insurance policies
- GP and NHS registration
