Returning the court defence form: the deadline

If your lender has started court action over mortgage arrears, you get a defence form to fill in and return before the hearing. What the form is, what happens if you miss the deadline, how to show the court you are dealing with the arrears, and what a repossession would mean for your home, your debts and your credit record.

Returning the court defence form: the deadline
Short answer

If your mortgage lender has started court action over arrears, the court sends you a defence form. You need to return the defence form before the hearing, and the form is your chance to put your side of the case on paper: what you can pay, what has changed, and what you are doing about the arrears1.

If your mortgage lender has started court action over arrears, the court sends you a defence form. You need to return the defence form before the hearing, and the form is your chance to put your side of the case on paper: what you can pay, what has changed, and what you are doing about the arrears1.

The form matters because the alternative is a court deciding without your explanation. Before the court date you can also contact the lender directly, or through an advice worker or your solicitor, to propose paying the instalments and clearing the arrears within a reasonable time, and to tell them if you have put the house up for sale or plan to shortly2.

Repossession is the end of a long process, not the start of one. Lenders must be fair and reasonable, and repossession should be the last option they consider3. If it does happen, the sale often raises less than the market value, you remain responsible for the shortfall, and the repossession stays on your credit record for up to six years4.

Return the defence form before the hearing

The defence form is the document that lets the court hear your position before it decides anything. Shelter's guidance is direct: return the defence form before the hearing1. If you are defending a county court claim, the form is the one marked N9B in the bottom right corner, titled "Defence and counterclaim"7. In Wales the same form is used, and the Welsh-language guidance says you will need to fill in the N9b defence form8.

If you are making a partial defence, you complete both the N9A and N9B forms, and both need to be sent to the court7. There is a separate admission form, N9C, which comes with the claim form and is used as a response to a return of goods claim9.

The form is not the only route. If you want to ask the court for a specific order, you use form N244: tick the box that says "defendant" in section 2, explain in question 3 what order you are asking the court to make and your reasons, tick "yes" at question 5 to have the application dealt with at a hearing, leave questions 6, 7 and 8 blank, then sign the statement of truth, keep a copy and send the form back to the court5. Question 11 of that form is where you fill in if you want to make the court aware that you, or someone giving evidence on your behalf, is vulnerable10.

The defence form is marked N9B in the bottom right corner.

When lenders start court action for mortgage arrears

Under the terms of most mortgages, a lender can usually start the process after two or three missed payments5. Lenders could previously start repossession orders after three months of arrears, but that changed in June 202311.

Before they go to court, lenders must give you a list of all missed payments, details of the total amount of your arrears, and information about how much you still owe on your mortgage12. That paperwork is what you use to build your response.

Missing a mortgage payment is treated seriously. Generally, missing a mortgage payment is considered one of the worst types of default, and lenders are likely to be reluctant to lend at any point afterwards13. That is why the earlier you engage with the lender, the more options tend to stay open.

If you are in Northern Ireland, the process and the help available are set out separately, and the guidance there covers what happens when a lender takes action against you2. In Scotland, the Home Owners' Support Fund is open to homeowners whose bank or mortgage lender wants to begin repossession proceedings in court14.

Showing the court you are taking steps, including selling your home

The court wants to see that you are doing something about the debt. Lenders should give you the chance to sell your home to pay off the debt, and you must be able to show that you are taking active steps to sell15.

If you are relying on income from a court or tribunal case, bring a letter from your solicitor explaining whether liability has been admitted, the prospect of winning or settling, the likely amount of damages or compensation if successful, and whether proceedings have been issued and the likely timescale2. If the arrears arose because of illness or a medical condition that may prevent you from working or making payments for a period, bring a letter from your GP, consultant or medical social worker explaining your condition2.

Bring all relevant documents to court, including all letters from the lender, notes of telephone calls or meetings with the lender, a completed budget form, proof of your salary or benefits, a letter from the estate agent if selling, a letter from the new lender if you have applied for a re-mortgage, proof of a change of circumstances such as a job offer, and proof of money due to you such as backdated benefit or compensation or copies of unpaid invoices2.

If you are selling, keep the evidence. Revenue Scotland, for example, will consider documentary evidence such as a copy of the signed disposition of sale, Land Registration documents, a solicitor letter stating the sale and date of entry, a Council Tax bill, a utilities bill or a bank statement16.

What happens if your home is repossessed and sold

If the court grants possession and the home is sold, it is usually sold as quickly as possible, often for less than the market value, meaning you would owe the bank even more than you would have if you had sold the property yourself17. That is the practical reason selling it yourself, with the lender's agreement, is usually the better outcome on the numbers.

The sale proceeds do not simply disappear into the lender's accounts. In Scotland, the lender must use the money from the sale to pay off the court costs, estate agent's and solicitor's bills, the mortgage and any second or third mortgages18. Selling costs are your responsibility, and your solicitor will confirm what these are; these costs are not taken from the sale proceeds19.

Anything left after the secured debts and costs are cleared comes back to you. Anything short of that becomes a debt you still owe.

Sale proceeds go first to costs and secured debts, not to the borrower.

Shortfall debt: you still owe what the sale does not cover

If the sale does not raise enough to clear the debt, you are still responsible for repaying the difference, known as the shortfall6. You will still owe money to your lender or mortgage indemnity insurer20. The same principle applies across secured borrowing: with a logbook loan, if the sale price does not cover the debt, you have to pay the shortfall21, and with hire purchase, if selling does not raise enough to pay off the remaining debt, you will still owe the money22.

The shortfall does not vanish because the home has gone. You will still owe money to your mortgage lender if selling does not pay off the full amount you owe23. If you had an interest-only mortgage and the term has ended without a repayment plan in place, the same shortfall logic applies to the capital23.

Where the property is in negative equity, the gap between what it sells for and what you owe is the shortfall, and it survives the sale24. Lenders are not allowed to base an affordability assessment on the equity in the property used as security, or to take account of an expected increase in property prices25, which means a rising market is not a route out of arrears.

Credit rating: a repossession stays on your report for up to six years

When your home is repossessed it stays on your credit record for up to six years4. A repossession stays on your credit report for up to six years and can affect your chances of getting credit from other lenders26. Your house being repossessed will affect your credit rating27.

The six-year rule is not unique to repossessions. Information about arrears stays on your credit report for six years28, and some information stays on your credit file for six years, including missed payments, defaults and court judgments30. Car repossession under hire purchase and conditional sale agreements is normally kept on your credit reference file for six years and can affect your ability to get credit31.

The practical effect is that a repossession follows you into your next application, whether that is a mortgage, a rental tenancy or a loan. Repossession can affect your housing options, and it might be harder to buy another home or rent privately32. If you are in Scotland and your home is in danger of being repossessed, the Mortgage to Rent scheme is open to applicants in that position33.

Where to get help

Free, impartial help exists and it is worth using before the hearing, not after. Shelter England publishes guidance on what to do if your lender starts court action1, and Shelter Cymru covers the same ground for Wales8. National Debtline has a guide to mortgage arrears5, and StepChange covers mortgage arrears and the court process35. Independent Age has advice for older homeowners at risk of losing their home3, and Housing Rights covers the Northern Ireland position37.

If you are in Scotland, the Home Owners' Support Fund is administered through mygov.scot and is open to homeowners whose lender wants to begin repossession proceedings in court14. In Northern Ireland, nidirect sets out what happens when a lender takes action2.

The Financial Conduct Authority's rules on repossessions apply to lenders, and the rules regarding repossessions are set out in its mortgage conduct handbook39. If you think a lender has not followed the rules, the Financial Ombudsman Service can look at complaints about mortgage lenders.

Frequently asked questions

What is repossession?

Repossession is when a lender takes back the home used as security for a mortgage or secured loan because the borrower has fallen behind on payments. The lender has to go to court first, and the most common reason for that court action is missed mortgage payments or a loan secured on the home. If the court agrees, the home is sold and the money goes towards the debt.

How many missed mortgage payments before a lender takes action?

Under the terms of most mortgages, a lender can usually start the process after two or three missed payments. Before going to court it must send you a list of all missed payments, the total arrears and how much you still owe on the mortgage. Lenders used to be able to start repossession orders after three months of arrears, but that changed in June 2023.

Is repossession always a last resort for lenders?

Guidance for lenders says repossession should be the last option they consider, and that they must be fair and reasonable and follow a mortgage pre-action protocol. In practice that means they should look at other ways to deal with the arrears first, such as a repayment plan, before asking a court to take your home.

Can a lender repossess my home over a secured loan, not just a mortgage?

Yes. If you have a mortgage or a secured loan on your home and you fall behind on payments, the lender can take court action. With a secured loan your home acts as security, so the lender could repossess and sell the property if you do not keep up repayments. The same applies to a mortgage backed by the Mortgage Guarantee Scheme.

Will my home be sold for less than it is worth?

It can be. A repossessed home is usually sold as quickly as possible, often for less than the market value, which can leave you owing more than if you had sold the property yourself. Lenders are not allowed to base an affordability assessment on the equity in your home or on expected house price rises, but that does not stop a forced sale achieving a lower price.

What costs does the lender take from the sale of my home?

In Scotland, the lender must use the money from the sale to pay off the court costs, estate agent's and solicitor's bills, the mortgage and any second or third mortgages. Selling costs are your responsibility and are not taken from the sale proceeds, so your solicitor will confirm what these are. Anything left after the secured debts are cleared comes back to you.

Will repossession make it harder to rent or buy another home?

It can. Repossession can affect your housing options, and it might be harder to buy another home or rent privately. It also affects your credit rating, and a repossession stays on your credit record for up to six years. If you are in Scotland, the Mortgage to Rent scheme is open to applicants whose home is in danger of being repossessed.

What happens if I do not return the defence form?

The defence form is your chance to set out your case before the hearing, so returning it before the hearing date matters. If you do not, the court may deal with the claim without your side of the story. You can still contact the lender directly, or through an advice worker or solicitor, before the court date to propose paying the instalments and clearing the arrears over a reasonable time.
