Mortgage Capacity Reports (FAQ)

Mortgage capacity reports: common questions

A mortgage capacity report is a formal document that sets out how much you (or you and a partner) may be able to borrow, based on an assessment of affordability and the way lenders typically consider income, expenditure and commitments. It’s often used when family finances are being negotiated, particularly after divorce or separation, where one party needs evidence of what is realistically achievable.

Below are the most common questions home buyers ask about mortgage capacity reports.

What is a mortgage capacity report?

A mortgage capacity report is an independent, structured assessment of borrowing potential, usually prepared for use in family law discussions such as mediation or court proceedings.

It typically considers:

• Your income and regular expenditure
• Existing financial commitments (such as loans or credit commitments)
• How lenders may treat those figures under their mortgage affordability rules
• The resulting estimated maximum borrowing amount

Because it’s written as a formal report, it’s designed to be clearer and more detailed than informal checks.

Why do people use mortgage capacity reports after divorce or separation?

After separation, there can be disagreement about what each person can afford—especially where a property needs to be bought, retained, or replaced.

A mortgage capacity report can help by providing evidence of:

• Whether a person is likely to be able to obtain a mortgage
• The practical borrowing limits based on current circumstances
• How changes in income, expenses, or support arrangements may affect affordability

This can make negotiations more grounded in facts rather than assumptions.

Is a mortgage capacity report the same as a mortgage in principle?

No. A mortgage in principle (or decision in principle) is generally an informal indication of potential eligibility.

A mortgage capacity report is different because it is prepared as a formal document that focuses on affordability assessment and borrowing capacity in a way that may be more suitable for mediation or court discussions.

What does a mortgage capacity report include?

While the exact format can vary, a typical mortgage capacity report for family proceedings will usually include a clear summary of:

• Your income and expenditure used for the assessment
• Your monthly affordability position
• Any existing debts/commitments taken into account
• An assessment of how lenders may apply their affordability criteria
• An estimated maximum borrowing figure (and sometimes commentary on scenarios)
• A written conclusion that can be used to support discussions

The aim is to produce a document that is understandable and structured for non-specialists as well as professionals.

What types of mortgage capacity reports are there?

Mortgage capacity reports are often prepared to match the circumstances of the case. Common formats include:

• Single capacity: for one person’s borrowing potential
• Joint capacity: for two people assessed together
• Scenario-based reports: where different outcomes or assumptions may be explored

Your report type will depend on how the finances are being discussed and what the report needs to evidence.

When might a mortgage capacity report be requested?

A mortgage capacity report isn’t automatically required in every situation. However, it may be requested where there is a need to evidence affordability and borrowing potential, for example when:

• One party wants to remain in or purchase a property
• There is disagreement about whether someone can rehouse independently
• Financial arrangements (such as maintenance or child-related costs) may affect borrowing
• A party claims they cannot obtain a mortgage without further support

How long does a mortgage capacity report take?

Timelines can vary depending on how quickly information is provided and how complex the case is. In practice, turnaround is often influenced by the completeness of the documents and the need to clarify income, expenses, and commitments.

How much does a mortgage capacity report cost?

Costs can vary depending on the type of report and the complexity of the assessment. The most accurate way to understand pricing is to check the specific report options available for your situation.

Will a mortgage capacity report guarantee I can get a mortgage?

No. A mortgage capacity report is an assessment of likely borrowing capacity based on affordability and lending criteria. It is not a mortgage offer and does not replace the full mortgage application process.

Even where a report indicates capacity, lenders may still require further checks and documentation when you apply.

How does a mortgage capacity report help in mediation or court?

A mortgage capacity report can provide independent evidence that helps explain:

• What borrowing may be realistically achievable
• How affordability is calculated from the figures provided
• The impact that financial commitments and support arrangements may have on borrowing

This can support clearer discussions and help reduce uncertainty during negotiations.

What information is usually needed to prepare a report?

To produce a meaningful assessment, you’ll typically need to provide information about:

• Income (including any relevant details about how it is earned)
• Regular monthly outgoings and commitments
• Existing debts and financial obligations
• Any relevant details that affect affordability

Providing accurate information helps ensure the report reflects your circumstances as closely as possible.

Is this only for buying a home?

Mortgage capacity reports are most commonly associated with residential property decisions in family proceedings, particularly where someone needs to understand whether they can purchase or refinance a home.

If your situation involves different property or lending circumstances, the report can be tailored to reflect what needs to be evidenced.

Important notes

Mortgage capacity reports are designed to support family law discussions by evidencing borrowing capacity. They do not replace regulated mortgage advice or the lender’s full underwriting process.

If you’re unsure which type of report best fits your circumstances, the key is to ensure the document aligns with what needs to be evidenced in your negotiations or proceedings.
