Navigating Mortgage Arrangements During a Relationship Breakup

Breakups and separations are never in anyone's plans. But if you are going through either, you need a plan for what to do with a house you may share with your partner.

Separation or divorce is a challenging and emotional time, and among the many considerations, one often involves the family home and its associated mortgage. In this article, we'll explore the key aspects of arranging a mortgage during a relationship breakup and provide insights into how to navigate this complex process.

Property Ownership:

The first crucial question when it comes to mortgage arrangements during a breakup is deciding who will retain ownership of the property. Whether it's one partner or the other, this decision impacts the next steps in the process.

Financial Considerations:

Once property ownership is determined, the next step is to evaluate the financial implications. This includes calculating how much money one party needs to transfer the property into their name. For example, if the property is worth $750,000 and the existing mortgage is $300,000, the transferring party may need to pay $150,000 to the other.

Affordability Assessment:

To ensure a smooth transition, it's essential to assess whether the person retaining the property can afford both the existing mortgage and the additional sum they need to pay. Banks typically prefer the combined loan-to-value ratio to remain below 80%. For instance, in the example mentioned, the ratio would be 40% ($300,000 + $150,000) divided by $750,000, resulting in 60%. This calculation helps determine if the person can comfortably manage the mortgage on their income alone.

Bank Requirements:

Banks often require specific documentation during this process, including a separation agreement and updated insurance information. The need for a registered valuation depends on the amount of money being borrowed. If the lending exceeds 80%, a valuation may be necessary.

Legal Contracts:

The type of legal contract or property sharing agreement in place can also influence the mortgage arrangements during a breakup. Some agreements outline property ownership and division percentages from the outset, simplifying the process.


Arranging a mortgage during a relationship breakup is a complex endeavor that involves property ownership decisions, financial assessments, legal contracts, and bank requirements. The goal is to ensure that the individual retaining the property can comfortably manage the mortgage on their own. Consulting with a mortgage advisor and legal professionals can provide valuable guidance and streamline the process, helping both parties move forward with clarity and financial stability.
