When Your Partner Has Bad Credit

You've found someone to build a life with. You want to buy a home together. There's just one problem: their credit history. Maybe they had financial difficulties before you met, or maybe something went wrong during your relationship. Either way, their credit score is affecting your shared dream of homeownership.

The Joint Application Dilemma
When you apply for a mortgage jointly, the lender assesses both applicants' credit histories. If one person has adverse credit — defaults, CCJs, missed payments, high debt levels — it affects the joint application. The lender sees the risk of the weaker applicant, not just the stronger one.
This creates a painful dilemma: include your partner and access both incomes but risk being declined, or apply alone and limit your borrowing to one salary.
Option 1: Apply Together (Joint Application)
When This Works
If your partner's credit issues are minor or old, a joint application may still succeed:
- A single missed payment over 2 years ago
- A small satisfied default from several years back
- A thin credit file rather than a bad one
- High credit card utilisation that can be reduced before applying
Which Lenders Are More Flexible?
Specialist lenders assess joint applications with adverse credit daily:
- Kensington Mortgages — experienced with one-applicant adverse credit situations
- Pepper Money — flexible criteria for joint applicants
- Aldermore — manual underwriting considers context
- Halifax (via intermediaries) — some flexibility depending on the severity
- Building societies — Bath, Furness, Loughborough — often assess cases individually
The Impact on Rates
Expect higher rates than you'd get with clean credit from both applicants. How much higher depends on the severity of the adverse credit and the LTV. Typically, you might see 1-3% above mainstream rates.
Financial association warning
Once you apply for a mortgage jointly — or even a joint bank account — you become financially associated on each other's credit files. This means your partner's credit history can affect YOUR credit score and future borrowing, even if you later separate. Think carefully before creating financial associations.
Option 2: Apply Alone (Sole Application)
When This Works
If your partner's credit issues are severe — active IVA, recent bankruptcy, multiple unsatisfied CCJs — applying alone keeps their credit problems out of the picture entirely.
The Affordability Challenge
The major downside: you can only use one income. If you earn £40,000 at 4.5x, that's £180,000 borrowing. With your partner's £30,000 added, it could be £315,000. That's a huge difference.
The Property Ownership Issue
If you apply alone, only your name goes on the mortgage. But you can still have both names on the property title. This is called sole mortgage, joint ownership — and not all lenders allow it.
If only your name is on the title, your partner has no legal ownership of the property. Consider a declaration of trust (also called a deed of trust) drawn up by a solicitor, which records both people's financial interests in the property regardless of whose name is on the title or mortgage.
Protect both parties
If one person owns the property and the other contributes to the mortgage, get a declaration of trust. This protects the non-owner's financial interest and avoids devastating disputes if the relationship breaks down.
Option 3: Joint Borrower Sole Proprietor (JBSP)
If applying alone doesn't give you enough borrowing, a JBSP mortgage lets a family member (usually a parent) join the mortgage application to boost affordability — without going on the property title. This way:
- Your parent's income helps you borrow more
- Your partner's credit doesn't affect the application
- The property is in your name (and potentially your partner's on the title, depending on the arrangement)
See our dedicated JBSP guide for full details.
Option 4: Wait and Improve
If your partner's credit issues are recent, the most cost-effective strategy might be patience:
How Credit Improves Over Time
- Missed payments: impact reduces after 12 months, significant reduction after 2 years
- Defaults: registered for 6 years, but impact diminishes each year. Satisfied defaults are viewed better
- CCJs: registered for 6 years. Satisfied CCJs under 12 months old are treated very differently from unsatisfied ones
- IVAs: remain on file for 6 years from the start date. After completion and removal, options open up dramatically
- Bankruptcy: discharged after 1 year, remains on file for 6 years
Active Steps While Waiting
Your partner can improve their credit position by:
- Getting on the electoral roll at your shared address
- Taking out a credit builder card and using it responsibly (small purchases, paid in full)
- Paying all bills on time — every on-time payment builds positive history
- Satisfying any outstanding defaults or CCJs — paying them off doesn't remove them, but "satisfied" is much better than "outstanding"
- Not applying for credit unnecessarily — each application leaves a footprint
- Checking all three credit reports for errors and disputing any found
Having the Conversation
Money conversations in relationships are hard. Credit problems can carry shame and anxiety. Some practical suggestions:
- Approach it as a team problem, not your partner's failure
- Focus on solutions, not blame
- Get both credit reports together — full transparency helps
- Set a realistic timeline — "in 12 months we'll be ready" is better than "we can never buy"
- Celebrate progress — a satisfied default or 6 months of clean payments is worth acknowledging
What About Marriage?
Getting married doesn't merge your credit files. You remain separate individuals for credit purposes. However, a joint mortgage or joint bank account creates a financial association that links your files. Marriage itself doesn't — but the financial products married couples typically share do.
The Practical Path Forward
Here's a decision framework:
- Both get credit reports — understand exactly what's on each file
- Assess the severity — is this something specialist lenders handle, or is it too recent/severe?
- Run the numbers both ways — what can you borrow alone vs jointly?
- Talk to a specialist broker — they can assess both options and tell you which lenders would work
- Decide: apply now or wait? — sometimes 6-12 months makes a dramatic difference to rates and options
- Protect yourselves legally — declarations of trust, financial agreements, etc.
You're Not Alone in This
An enormous number of couples face this exact situation. One partner's past financial difficulties shouldn't define your future together. With the right advice, the right lender, and sometimes a little patience, buying a home together is usually achievable.
