The letter arrives on a Tuesday, addressed to you personally. NatWest is demanding £140,000 under a personal guarantee your husband gave in 2019 when the company drew down a growth loan. You do not remember signing anything for the business, because you did not. What you signed, five years ago, was a mortgage variation when you added your name to the family home.
The bank’s argument is that the charge over the house supports the guarantee. Your solicitor’s advice is that before they can enforce against your half of the equity, they have to prove you received independent legal advice, that you understood the risk, and that the bank satisfied the eight-point protocol in Royal Bank of Scotland v Etridge (No 2) [2001] UKHL 44.
If they cannot, the security may be unenforceable against your interest.
That is the shape of the question. The default position in English law is that one spouse is not liable for the other’s business debts. But there are specific routes by which liability crosses the marital line, and the default only holds if none of those routes has opened.
We walk you through the routes that matter, the Etridge protections the bank has to clear, and what the Insolvency Act 1986 does to jointly-owned property when one spouse is made bankrupt. We see the same bundle of documents every week; in our experience the outcome is nearly always decided by which boxes the lender did or did not tick in 2018 or 2019, not by what the letter threatens now.
The Default Position on Personal Liability for a Spouse’s Business Debts
Marriage, civil partnership, or cohabitation does not, on its own, make you liable for your partner’s business debts. That is the starting point, and it is true whether the business is a limited company, a partnership, or a sole tradership.
The principle is an old one. A limited company has separate legal personality under Salomon v A Salomon & Co Ltd [1897] AC 22, so its debts are its own, not its directors’ and not its directors’ spouses’. Our guide to limited liability sets out the separation more fully.
A sole trader’s business debts are personal to them, but they do not automatically become their spouse’s debts merely because the two are married.
What the bank wants, when it lends to a small owner-managed company, is something extra to that default. A personal guarantee from one director, ideally both. Security over a jointly-owned property. A co-borrower on the loan.
Those are the instruments that cross the marital line and create exposure for the non-trading spouse. Without one of them, you are insulated.
The Routes by Which You Can Become Liable for Your Spouse’s Business Debts
The routes cluster into four recognisable categories. If you are reading this letter from a lender, the first task is identifying which of these applies to your specific paperwork.
Joint borrowing. A joint business loan, a joint overdraft, or a business credit card held in joint names. Both signatories are jointly and severally liable for the full balance. The lender does not have to pursue one before the other.
Co-guarantor on a personal guarantee. You signed the PG document alongside your spouse, typically for a bank facility or a landlord. Once the company defaults, the lender can call either of you, or both, for the full amount.
Co-director of the business. If you are a director, the wrongful trading and misfeasance provisions in sections 212 and 214 of the Insolvency Act 1986 apply to you personally, even if your involvement was nominal. Being “just on the paperwork” is not a defence once things go wrong.
Business partner (partnership or LLP member). In an ordinary partnership, every partner is jointly and severally liable for partnership debts. In an LLP, liability is limited unless personal guarantees were given. If you registered with HMRC as a partner alongside your spouse, that exposure is real.
The fifth route is the one directors often overlook: security granted over the matrimonial home. That is not the same as being liable under a personal guarantee. The bank’s charge over the property secures the company’s debt or the guarantee; it does not make you a debtor.
But if the company defaults and the guarantee is called, the bank can apply to force sale of the property to realise its security. Our guide to the personal guarantee on company liquidation covers the enforcement sequence in detail.
The Etridge Protocol: Protection for Spouses Who Signed Personal Guarantees
The leading case on spouse guarantees is Royal Bank of Scotland v Etridge (No 2) [2001] UKHL 44. The House of Lords held that when a wife (or husband) provides a guarantee or security to support a loan to the other spouse’s business, the lender is put on inquiry as to the possibility of undue influence or misrepresentation.
To protect itself against later challenge, the lender must satisfy an eight-point protocol. In practice that means the non-business spouse must receive independent legal advice from a solicitor who has not acted for the business.
That solicitor must have seen the underlying loan agreement and the borrower’s financial position, and must have explained the document’s effect in a face-to-face meeting.
The solicitor then writes to the bank confirming the advice was given. Without that certificate, and without the procedural steps behind it, the bank’s security is vulnerable to being set aside on the ground of undue influence.
This is the door we ask spouses to check first when a guarantee is called. If the 2019 paperwork shows you met your own solicitor, read the bank’s letter, and signed in front of them, the Etridge defence is weaker.
If you were handed the document at the kitchen table with “just sign here, love, it’s a formality”, and no solicitor was involved, there is a case to be argued. The difference can be the equity in your half of the house.
Joint Accounts, Joint Cards, Joint Mortgages and Liability for Business Debts
Joint bank accounts and joint credit cards are a regular route for unintended spouse liability. The legal position is unforgiving: both parties are jointly and severally liable for the full balance, regardless of who incurred the spending.
Where the couple share a joint current account and one of them is running business expenses through it, the unused limit or the overdraft facility is backed by both of them. When the spouse’s business fails and the account is left overdrawn, the bank can collect from either party.
Joint mortgages are more complex. The mortgage itself is a joint debt. If one spouse’s business fails, that does not automatically trigger default on the mortgage unless the lender has required assignment of rental income, cross-default, or taken a second charge to support business borrowing.
If the mortgage is performing, the matrimonial-home protection under the Insolvency Act 1986 kicks in, which we set out below.
Personal Liability When Your Spouse Becomes Bankrupt
If your spouse’s business fails, their personal guarantees are called, and they cannot pay, they may end up bankrupt. Bankruptcy under the Insolvency Act 1986 vests their assets in a trustee in bankruptcy, who has a duty to realise the estate for creditors.
Two questions immediately arise for you, the non-bankrupt spouse.
Your own assets. The trustee has no claim on property owned solely by you, provided it is genuinely yours. Bank accounts in your sole name, a car registered to you, inheritance money in your name. Those remain yours.
Jointly-owned property. The matrimonial home is the usual concern. Where the property is held as beneficial joint tenants or tenants in common, the trustee is entitled to the bankrupt spouse’s beneficial share, not yours.
Section 336 of the Insolvency Act 1986 and section 335A are the provisions that govern what happens next with the family home. The trustee can apply to court for an order for sale, but the court will balance the interests of the creditors, the needs of any children, and the position of the non-bankrupt spouse.
During the first year after bankruptcy, the court will typically not force sale unless exceptional circumstances exist. After one year, under section 335A(3), the interests of creditors are assumed to outweigh all other considerations unless “exceptional”.
The trustee usually ends up with a buy-out from the non-bankrupt spouse, or a forced sale with the bankrupt’s half of the net equity going into the estate.
How to Protect Yourself From Personal Liability on a Spouse’s Business Debts
If the business has been trading for a while and no call has yet been made, the protective moves sit in three areas.
Do not sign anything on business banking paperwork that you have not read. Personal guarantees, co-borrower agreements, second charges, unlimited mortgage extensions. These are the instruments by which liability crosses. If the bank wants your signature, the bank wants you on the hook.
If you must sign, insist on independent legal advice. A separate solicitor for you, not the business’s solicitor. That is the Etridge defence you are preserving for the day the guarantee is called. The cost of an hour’s advice is trivial relative to what it buys.
Keep your own assets clearly yours. A sole-name bank account for your salary. Savings in your name. An inheritance ring-fenced. Joint ownership blurs the line, and blur works against you if creditors come calling.
Once a PG is called or a statutory demand is served on your spouse personally, the protective window is narrower. The focus shifts to the Etridge defence, to bankruptcy-vs-IVA planning on your spouse’s side, and to the home’s position under section 336.
Our note on joint and several liability covers the HMRC angle where your spouse has signed a joint-and-several-liability notice.
Personal Liability for a Spouse’s Business Debts: What to Check in Your Paperwork
Before you ring a lender to protest, open the filing cabinet. The documents that determine your exposure are specific and identifiable.
The original business loan agreement. Look for your name alongside your spouse’s as a borrower or as a guarantor. Initialled pages count.
The overdraft facility letter. Personal guarantee clauses are often buried on page three or four under “Security”.
The mortgage deed and any subsequent variations. A second charge to support business lending is the instrument the bank will rely on if the guarantee is called.
Any landlord’s guarantee. Commercial leases often come with spouse PGs where the business is trading from premises.
Companies House filings. If you are listed as an active director of the business, your exposure is not “spouse of director”, it is “director”. The two are not the same legally.
We ask spouses to assemble that bundle before the first call. Our conversation is much sharper when the paperwork is in front of us.
Guessing at which documents you signed is how most of the anxiety accumulates. The documents themselves usually tell a tighter, more navigable story than the one you have been telling yourself since the letter arrived.
Your Next Step on Liability for a Spouse’s Business Debts
The verdict splits into two camps. If you have never signed a personal guarantee, never co-signed on business borrowing, are not a director or partner in the business, and the matrimonial home does not carry a second charge for the company, your exposure is likely zero.
The creditor’s letter is aggressive positioning, not a legitimate claim. A short letter from a solicitor back to the lender usually closes it down.
If you did sign something, the question is not whether you are liable at all but how much of the Etridge protocol the bank cleared at the time. That is a paperwork-led argument, and the sooner a solicitor or an IP reviews the bundle, the sooner you know where the defence sits. Leaving it until the bank has issued proceedings is the expensive route.

FAQs on Personal Liability for a Spouse’s Business Debts
Am I automatically liable for my spouse’s business debts?
No. Marriage or civil partnership does not create automatic liability for your spouse’s business debts. Liability arises only where you have signed something (a personal guarantee, a joint loan, a co-borrower agreement), are a director or partner in the business, or have property charged to secure the business’s borrowing.
What is the Etridge protocol?
The eight-point test from Etridge (No 2) [2001] UKHL 44. Where a spouse guarantees or secures the other spouse’s business borrowing, the lender must ensure independent legal advice is given, the solicitor sees the loan paperwork, and consequences are explained face to face. A bank that cannot show compliance risks having its security set aside for undue influence.
Can the bank take my house if my spouse’s business fails?
Only where there is a charge supporting the debt or a called guarantee, and only to the bankrupt spouse’s beneficial share. The trustee’s route to forced sale is sections 335A and 336 IA 1986. For the first year post-bankruptcy, the court weighs the non-bankrupt spouse’s and children’s interests. After a year, creditor interests presumptively prevail.
What happens to a joint bank account if my spouse goes bankrupt?
The bank typically freezes the joint account on being notified of the bankruptcy. The trustee in bankruptcy is entitled to the bankrupt spouse’s share of any credit balance. Any overdraft is joint-and-several, so the bank can pursue you for the full outstanding amount notwithstanding the bankruptcy. You should open a sole-name account before the bankruptcy order, not after.
Is my spouse’s sole trader debt different from company debt?
Yes. A limited company has separate legal personality per Salomon v Salomon [1897] AC 22, so its debts are its own. A sole trader’s business debts are personal to them. Either way, those debts do not automatically transfer to a spouse. They transfer only if you signed something creating liability, or if the debt is secured on jointly-owned property.
Can I be held liable as a director if I was only a director on paper?
Yes. Being a registered director, even a “silent” one, means sections 212 (misfeasance) and 214 (wrongful trading) of the Insolvency Act 1986 apply to you if the company goes into insolvent liquidation. Nominal directorship is not a defence. Resignation before any warning signs crystallise is the clean position.
