Adding someone to a mortgage might seem straightforward, but it’s a decision that carries significant financial and legal weight. Whether you’re moving in with a partner, making a long-term commitment, or simply looking to share the load, it’s essential to understand the full picture before proceeding.
How does the process work? What costs are involved? Will it impact your credit or future plans? In this article, we’ll break down everything you need to know about adding someone to a mortgage, help you understand if you can add someone to a mortgage with your current circumstances, and make sure you’re fully informed before taking that crucial step.
Read on as we explore the key considerations, potential pitfalls, and the process itself, so you can make the right decision with confidence.
Can You Add Someone to a Mortgage?
Yes, you can add someone to a mortgage, but it’s a process that requires careful consideration and approval from your mortgage lender. There are various situations where adding another person to your mortgage makes sense, such as moving in with a partner, getting married, or even having a family member contribute to the property purchase. However, before proceeding, it’s essential to understand the implications, both legal and financial, to ensure it’s the right decision.
When Is Adding a Person to a Mortgage a Good Idea?
Adding someone to your mortgage can be beneficial in certain circumstances. For instance:
- Shared Financial Responsibility: If you’re sharing your home with someone, splitting the mortgage repayments can make the cost more manageable (especially to help cover the average cost of a mortgage in the UK).
- Increased Borrowing Power: By combining incomes, you may be able to borrow more, potentially allowing you to buy a bigger property or secure a more competitive interest rate.
- Formalising Ownership: If you’ve entered into a long-term relationship or marriage, adding your partner to the mortgage may feel like the right step to reflect your shared commitment.
Legal and Financial Factors to Consider
Before asking, “Can I add someone to my mortgage?”, it’s crucial to consider the potential consequences:
- Credit Checks and Affordability Assessments: Your lender will need to conduct credit checks and assess the financial situation of the person you’re adding. If they have bad credit or they have existing debt, this could negatively impact your mortgage application or even result in higher interest rates.
- Joint Liability: Once a person is added to the mortgage, both parties become jointly liable for repayments. This means that if one person fails to make their contribution, the other person is still legally responsible for covering the full payment.
- Types of Ownership: When adding someone to a mortgage, you’ll need to decide between Joint Tenants and Tenants in Common, which affects how the property is owned and what happens if one person passes away or wants to sell their share.
While it can be a practical solution for many, it also comes with certain risks and potential downsides that shouldn’t be overlooked.

On the positive side, adding a person to your mortgage can improve your overall financial situation. For example, combining incomes can increase your borrowing capacity, allowing you to qualify for a better mortgage deal or purchase a more desirable property. It also formalises ownership, ensuring that both parties have a legal claim to the property. This can be particularly beneficial if you’re married or in a long-term partnership and want equal stakes in your home.
However, it’s important to be aware of the negatives before jumping in. One significant downside is the issue of joint liability. Once someone is added to your mortgage, both parties are equally responsible for the repayments. This means that if one person encounters financial difficulties—such as losing their job or facing unexpected expenses—the other person is still legally required to cover the full mortgage payment. This can create financial strain and potentially lead to missed payments, damaging both parties’ credit scores.
Imagine This…
Imagine this scenario: You’ve been living with your partner for a few years, and you decide it’s time to buy a house together. To strengthen your mortgage application, you decide to add them to your existing mortgage. Everything goes smoothly until a year later, your partner faces financial issues and can no longer contribute to the mortgage payments. Since both names are on the mortgage, you’re left having to cover the entire repayment on your own. If you struggle to keep up with the increased financial burden, you could fall behind on payments, which could lead to serious consequences like credit score damage or even repossession.
In addition, you need to think about the long-term implications. What happens if your relationship changes? We deal with loads of mortgages from couples who have split up. If you split up, you’ll both remain financially tied to the property, making it difficult to sell, refinance, or make any changes without mutual agreement. Legal disputes over ownership shares and rights to stay in the property can be costly and emotionally draining.
Considering the Bigger Picture
It’s not that adding someone to your mortgage is necessarily a bad idea, but it does require careful thought and open communication. You’ll need to be confident in the financial stability of the person you’re adding and consider how your circumstances might change over time. The best approach is to discuss your options with our mortgage advisors, who can guide you through the process, help you understand the risks, and explore alternative arrangements if needed.
In the UK, most lenders allow up to four people to be named on a single mortgage. However, while up to four people can be listed, lenders typically only take the top two highest incomes into account when calculating affordability. This means that even if there are multiple applicants, the combined borrowing power is based on the primary earners.

How Joint Mortgages Work
A joint mortgage involves more than one person applying for a mortgage together, and all parties are equally responsible for making the repayments. This type of arrangement is common among couples, friends buying together, or family members who want to co-own a property. Joint mortgages can be flexible and offer various ownership structures depending on your goals and relationships.
When adding someone to a mortgage, it’s crucial to understand the different types of legal ownership available, as this will determine how the property is shared and what happens in the event of a sale or death. There are two main types of tenancies in the UK:
- Joint Tenants:
Under a joint tenancy, all owners have an equal share in the property. If one person passes away, their share automatically transfers to the remaining owners. This option is commonly chosen by married couples or long-term partners, as it offers equal ownership and simplifies inheritance. However, this also means that if you want to sell the property or make changes, all owners must agree. - Tenants in Common:
Tenants in common is a more flexible arrangement, allowing owners to have different ownership shares (e.g., 70/30). This structure is ideal if you’re buying with friends, siblings, or in cases where one person contributes more financially. In a tenants in common agreement, each owner’s share can be passed on through a will, rather than automatically going to the other owners. This gives you more control but requires clear agreements to avoid disputes later on.
While having multiple owners can make purchasing a property more affordable, it also introduces shared responsibilities. Everyone on the mortgage is jointly liable, meaning if one person can’t make their repayments, the others must cover the shortfall. This can lead to personal relationships between friends and family members in ruins (and we’ve seen this unfold).
How Do I Add Someone to My Mortgage?
The process is more involved than simply calling your lender, as there are several legal, financial, and administrative steps to consider. Below is a detailed, step-by-step guide to help you understand what’s involved. If you need more information, specific to your circumstance, then please get in touch with our team today.

1. Contacting Your Lender
The first step is to get in touch with your current mortgage lender to inform them of your intention to add someone to the mortgage. Your lender’s approval is crucial since they’ll need to assess whether the additional person meets their lending criteria. Some lenders might allow it, while others may require you to remortgage, potentially switching to a new deal or rate.
At this stage, ask your lender about any conditions, costs, or documentation needed. It’s also wise to check whether adding someone might affect your mortgage terms, such as interest rates or the repayment period.
2. Affordability and Credit Checks (Association of Credit)
Once your lender agrees in principle, they’ll carry out affordability and credit checks on the person you wish to add. This is a critical part of the process, as the lender needs to ensure that the new borrower can afford the mortgage payments and that their financial history doesn’t pose a risk.
These checks usually involve:
- Income Assessment: The lender will review the combined household income and expenses to determine if adding the person strengthens or weakens your affordability.
- Credit History: The new person’s credit report will be examined. A poor credit score, high levels of existing debt, or past missed payments could result in the lender rejecting the application or offering less favourable terms.
- Association of Credit: By adding someone to your mortgage, you become financially linked to them. This creates an association of credit, meaning their financial behaviour could impact your credit rating and vice versa. If they have a poor credit history, it could affect your ability to borrow in the future.

3. Legal Documentation and Updating the Mortgage Deed
If the affordability and credit checks are satisfactory, the next step involves updating the legal documents associated with your mortgage. You’ll need a solicitor or conveyancer to handle the legal process of adding a new name to the property’s title deeds and the mortgage agreement.
This stage includes:
- Updating the Title Deeds: The property’s ownership details will be amended to reflect the new arrangement. You’ll need to decide whether you’ll be Joint Tenants or Tenants in Common, which determines how ownership is shared and what happens in case of death or sale.
- Mortgage Deed Amendment: The mortgage contract will also be updated to include the new borrower. This is a legally binding document that confirms everyone on the mortgage is jointly liable for repayments.
Your solicitor will guide you through signing these documents and ensuring they’re correctly registered with the Land Registry.
4. Costs Involved (Legal, Lender, and Valuation Fees)
Adding someone to a mortgage isn’t free, and there are several costs to budget for:
- Legal Fees: You’ll need to pay for a solicitor or conveyancer to handle the paperwork, update the deeds, and register the changes with the Land Registry. These fees can vary but typically range from £300 to £800.
- Lender’s Fees: Your mortgage lender may charge an administrative fee for processing the change. This could be a fixed fee or a percentage of the mortgage balance, depending on the lender.
- Valuation Fees: In some cases, the lender may require a new property valuation, especially if adding someone involves remortgaging or changing the mortgage deal. Valuation fees can range from £150 to over £500 depending on the property’s value.
- Stamp Duty (if applicable): In rare cases, adding someone to your mortgage could trigger a stamp duty charge, particularly if ownership shares are adjusted and exceed the current stamp duty threshold.
Benefits of Adding Someone to a Mortgage
- Increased Borrowing Power
One of the main benefits of adding someone to a mortgage is the potential for increased borrowing power. When two or more people apply for a mortgage together, lenders take both incomes into account. This can boost your overall affordability, enabling you to borrow more than you could on your own. For couples, this often means they can purchase a larger or better-located property, or even secure a more competitive mortgage deal due to the higher combined income. - Shared Financial Responsibility
Another key advantage is the ability to share the financial responsibility. When you add someone to a mortgage, you can split the monthly repayments, making them more manageable. This can ease the financial burden and help both parties maintain a healthier budget. For instance, if you’re moving in with a partner, sharing the cost of the mortgage could free up funds for other goals, such as savings or investments. - Improved Mortgage Approval Chances
In some cases, adding someone to your mortgage can improve your chances of being approved. Lenders assess applications based on affordability and financial stability. If the person you’re adding has a strong credit history and stable income, this can work in your favour. A joint application that demonstrates financial security is more likely to be approved, especially if one person has a weaker credit profile on their own.
These benefits can make adding someone to your mortgage a smart move, provided the circumstances are right. However, it’s crucial to balance these advantages against the potential risks.

Negatives of Adding Someone to a Mortgage
While the benefits are appealing, it’s important to be aware of the potential downsides. There are several negatives of adding someone to a mortgage that could impact both your financial situation and personal relationships.
- Joint Liability for Mortgage Repayments
One of the most significant drawbacks is the issue of joint liability. When you add someone to your mortgage, both parties become fully responsible for the entire mortgage repayment. This means that if one person cannot make their contribution, the other person is still legally obligated to cover the full amount. This can create financial stress, especially if one person faces unexpected financial difficulties, like job loss or a sudden expense. - Impact on Credit Scores and Financial Standing (Association of Credit)
Adding someone to your mortgage creates a financial link between you and that person, known as an association of credit. This connection means that any negative financial activity by one party, such as missed payments or accumulating debt, can affect both people’s credit scores. A poor credit score can limit your ability to secure loans or other financial products in the future. If the person you’re adding has a shaky financial history, it could even lead to higher interest rates or difficulty in getting approved. - Potential Complications in Case of Relationship Breakdowns
Adding someone to a mortgage ties your finances together, which can be problematic if the relationship changes or ends. In the event of a breakup or falling out, both parties are still legally responsible for the mortgage, which can lead to complicated disputes over property ownership and finances. Selling the property, refinancing, or removing someone from the mortgage may require agreement from both parties, which isn’t always straightforward. Legal fees, delays, and emotional stress can be the result, making it essential to consider the long-term implications before making this decision.
These negatives of adding someone to a mortgage highlight why it’s important to carefully weigh the pros and cons. While there are clear benefits, it’s crucial to ensure that both parties fully understand their responsibilities and the potential risks involved.
If you’re considering adding someone to your mortgage, its important both you, and the person(s) you’re looking to add understand both the pro’s and con’s before committing. We can help provide you all the information you need, so that you can make a more informed decision, avoiding unexpected complications down the line.
What Type of Tenancies Are There When Adding a Person to a Mortgage?
When adding a person to your mortgage, it’s essential to understand the types of tenancies available, as these will determine how the property is owned and what happens in various situations. The two main options are Joint Tenants and Tenants in Common. The choice between them depends on your relationship, financial goals, and what you want to happen to the property in the event of death or separation. Here’s a breakdown of the differences:
Joint Tenants
When you choose to be Joint Tenants, both parties have equal ownership of the property. Regardless of who contributes more financially, the property is owned equally. One key feature of being Joint Tenants is the right of survivorship. This means that if one person passes away, their share of the property automatically transfers to the surviving owner(s). This is commonly chosen by married couples or long-term partners who wish for seamless inheritance and equal ownership.
However, this structure can be limiting if your financial contributions are uneven or if you want more flexibility in determining who inherits your share of the property. In cases of relationship breakdowns, selling or dividing the property requires the agreement of both parties.
Tenants in Common
As Tenants in Common, ownership shares can be split unequally. For example, you might own 70% of the property while the other person owns 30%, depending on your financial contributions. This option is ideal for friends, family members, or business partners who want ownership to reflect individual investments.
Unlike Joint Tenants, there is no automatic right of survivorship. Instead, each person’s share of the property can be passed on separately through a will. This offers greater control over inheritance planning but can lead to complications if co-owners pass away or disagree on selling the property.

How to Add Your Wife or Husband to House Deeds in the UK
If you’re looking to add your spouse to your house deeds in the UK, it’s a straightforward process, but it involves both legal and financial considerations. Here’s a step-by-step guide on how to add your wife to house deeds in the UK:
- Inform Your Mortgage Lender
Before proceeding, you must first contact your mortgage lender. Adding someone to the property deeds typically requires their approval, especially if there’s an outstanding mortgage. The lender may want to conduct affordability checks to ensure the change won’t affect the ability to repay the mortgage. In some cases, the lender may require you to remortgage. - Hire a Solicitor or Conveyancer
Adding your wife to the house deeds is a legal process that requires the services of a solicitor or conveyancer. They’ll handle the legal documentation needed to update the property’s title deeds. This process includes drafting a Transfer Deed (TR1 form), which is submitted to the Land Registry. - Decide on Joint Tenants vs. Tenants in Common
As discussed earlier, you’ll need to choose the type of ownership that suits your circumstances—Joint Tenants or Tenants in Common. Your solicitor can help you understand which option is best for your situation. - Complete the Transfer and Register the Change
Your solicitor will complete the necessary paperwork and submit it to HM Land Registry. This will officially add your wife’s name to the property deeds. You’ll also need to update your mortgage documents to reflect the new ownership. Your solicitor will coordinate this process with your lender. - Consider the Costs
There are several costs involved in adding your wife to the house deeds. These include:- Legal Fees: Solicitors typically charge for preparing the transfer deed and handling the registration with the Land Registry.
- Land Registry Fees: A fee is payable to HM Land Registry to update the title deeds. The cost varies depending on the property’s value.
- Stamp Duty (if applicable): If the transfer involves giving your wife a share of the property that exceeds the stamp duty threshold, you may need to pay stamp duty. This is usually only relevant if the property is high in value or if there’s a mortgage transfer involved.
Adding your husband or wife to your house deeds is a significant step that formalises shared ownership. Make sure to get expert advice to ensure the process goes smoothly and that all legal obligations are met.
Can I Remove Someone from My Mortgage?
Yes, you can remove someone from your mortgage. There are situations where removing a name from a mortgage becomes necessary, such as relationship breakdowns, divorce, or when one person wants to buy out the other.

1. Contact Your Mortgage Lender
The first step is to get in touch with your mortgage lender. Inform them of your intention to remove someone from the mortgage. They’ll need to assess whether the remaining borrower can manage the mortgage payments on their own. This usually involves a new affordability check, which looks at the remaining borrower’s income, credit history, and overall financial situation.
2. Affordability Checks for the Remaining Borrower
Your lender will perform an affordability assessment to ensure that the person staying on the mortgage can comfortably cover the payments. This check includes:
- Income Verification: They will review the remaining borrower’s income to confirm they can handle the mortgage alone.
- Credit History Review: The lender will check the credit report of the remaining borrower to ensure their credit score is strong enough.
- Overall Financial Stability: They will consider other financial factors, such as existing debts and expenses.
If the remaining borrower doesn’t meet the lender’s criteria, you might need to explore other options or consider remortgaging.
3. Remortgaging or Transferring the Mortgage
To remove someone from the mortgage, you might need to remortgage the property solely in the name of the remaining borrower. This process is similar to applying for a new mortgage and involves:
- Applying for Remortgage: The lender will reassess the mortgage application based on the remaining borrower’s financial situation.
- New Mortgage Terms: You might be offered a new interest rate or loan terms.
Alternatively, if you’re not changing the mortgage deal but simply updating ownership, you may need a transfer of equity. This involves updating the property’s deeds to reflect the new ownership while keeping the existing mortgage arrangement.
4. Legal Documentation and Costs
Removing someone from a mortgage involves legal and administrative tasks:
- Legal Fees: You’ll need a solicitor or conveyancer to handle the paperwork for the mortgage and property deeds. This includes drafting a Transfer of Equity document.
- Land Registry Fees: There’s a fee to update the property’s title with HM Land Registry.
- Mortgage Costs: If you’re remortgaging, there might be additional costs, such as an early repayment charge if breaking out of a fixed-rate mortgage.
5. Understanding the Financial Impact
It’s important to be aware of the financial implications:
- Higher Interest Rates: If the remaining borrower’s credit profile isn’t strong, they might face higher interest rates.
- Equity Buyout: If the departing party is entitled to a share of the property’s equity, you may need to arrange a buyout, which can involve further negotiation and financial planning.

FAQs
Can you add someone to a mortgage without remortgaging?
In some cases, it is possible to add someone to your mortgage without remortgaging, particularly if the lender allows a transfer of equity. This process involves updating the property’s title deeds and the mortgage agreement to include the new borrower. However, if your lender requires it or if the financial situation changes significantly, remortgaging might be necessary.
How many people can be on a mortgage in the UK?
In the UK, most lenders allow up to four people to be named on a single mortgage. However, only the incomes of the top two highest earners are usually considered for affordability assessments. It’s essential to check with your lender for their specific policies.
What happens if the person added to the mortgage has poor credit?
Adding someone with poor credit to your mortgage can impact both parties. The lender will assess the combined credit profiles, and a poor credit history may affect your borrowing terms or even lead to a higher interest rate. It’s important to consider the potential impact on your credit score and overall mortgage terms before proceeding.
