Personal Guarantees and Surety on a Business Loan: What SA Directors Are Signing
What signing surety on a business loan means

Your company is approved for funding. The offer arrives with a loan agreement and, a few pages in, a second document with your name on it rather than the company’s. It is usually called a deed of suretyship, and it is the one page in the pack that is about you personally.
Most directors sign it without much thought, because it looks like standard paperwork and because the funding is needed now. This guide explains what that document actually does, which clauses matter, and what to ask before you sign. It sits alongside our guide to how business loans work in South Africa, which covers the loan agreement itself.
This article is general information for South African business owners, not legal advice. Every deed of suretyship is different. If you are being asked to sign one for a significant amount, have an attorney read it first.
What is a suretyship?
A suretyship is an agreement in which one person (the surety) undertakes to a creditor that they will pay a debt owed by someone else (the principal debtor) if that debtor fails to pay. In a business loan, the principal debtor is your company and the surety is you, the director or shareholder.
Three features define a suretyship under South African law:
It must be in writing.
Section 6 of the General Law Amendment Act 50 of 1956 provides that a suretyship is not valid unless its terms are embodied in a written document signed by or on behalf of the surety. A verbal promise to “stand surety” is not enforceable.
It is accessory.
A suretyship depends on a valid underlying debt. If there is no valid principal debt, there is nothing for the surety to be liable for, as Shepstone & Wylie explains
It is personal.
The surety’s own assets, including savings, investments, vehicles and property, stand behind the promise.
The document you sign is usually called a deed of suretyship, a surety agreement or a suretyship agreement. The terms are used interchangeably.
Is a personal guarantee the same as surety?
In everyday use, yes. In law, not quite. A suretyship is an accessory obligation that depends on the company’s debt. A true guarantee creates an independent, primary obligation to pay that can exist separately from the underlying debt. Many lenders use “personal guarantee” loosely to describe what is legally a suretyship, so read the document for what it does rather than what it is called.
| Suretyship | Guarantee | Collateral (security) |
What backs the loan | Your personal promise to pay the company’s debt | Your independent promise to pay a set amount | A specific asset, such as property or equipment |
Depends on a valid company debt? | Yes, it is accessory | No, it stands on its own | Yes, it secures that debt |
Must be in writing? | Yes, by law | Advisable, not strictly required | Yes, via the security document or bond |
What is at risk | Your personal estate | Your personal estate | The pledged asset |
Where you usually see it | Business loans, supplier credit, leases | Bank and performance guarantees, trade finance | Secured loans, asset finance, property finance |
It is also why the difference between secured and unsecured business loans is a separate question from surety. Secured means a specific asset is pledged. A director’s suretyship is a personal undertaking, not a pledge of an asset, so an unsecured loan can still come with one. The difference also shows up in pricing, which our guide on how business loan interest rates work covers.
Why lenders ask directors to sign surety
A private company is a separate legal person. Its debts are its own, and in the ordinary course the directors and shareholders are not personally liable for them. That separation is the main reason people trade through a company rather than as a sole proprietor.
For a lender, the same separation is a risk. If the company fails, the only assets available are the company’s. A suretyship bridges that gap by putting the people who control the business behind the debt. It also aligns incentives: a director who is personally on the hook has every reason to keep the repayments up.
Lenders are most likely to ask for surety when:
- The business is young or has limited trading history. See our guide to startup funding options for businesses under two years old.
- The loan is large relative to the company’s balance sheet.
- No specific asset is being pledged.
- There is a small number of owners who are also the directors.
This is where the line between business and personal borrowing blurs. Our comparison of business loans vs personal loans explains why keeping the two separate matters, and a signed suretyship is the point at which they partly reconnect. Banks and alternative lenders also approach security differently, which we cover in bank loan vs alternative lender.
What you have to sign to get a business loan in South Africa
A suretyship is one document in a pack. Knowing what else is in it tells you where your personal exposure sits and where it does not. For most business loans in South Africa, a company director signs some combination of the following:
The loan agreement. Signed by the company, through a director authorised to do so. This is the debt itself: capital, rate, fees, term and repayment schedule.
A resolution of directors. Confirms the board approved the borrowing and named who may sign for the company.
A debit order or collection mandate. Authorises the lender to collect the instalment from the business account.
A deed of suretyship. The only document in the pack that creates personal liability. Not every lender asks for one.
FICA and verification documents. Identity documents, proof of address, company registration documents and business bank statements. These create no liability; they support the assessment.
Only the suretyship moves risk from the company to you personally. Everything else binds the business. If you are unsure which of these a lender expects, the qualifying criteria for a business loan set out the standard requirements and the documents behind them.
The clauses that decide how much you are signing for
Two deeds of suretyship can look almost identical and carry very different risk. These are the clauses to find and read, in the order they usually matter. They belong on the same list as what to check in your loan agreement.
“As surety and co-principal debtor”
This phrase appears in most commercial deeds. You remain a surety, but you accept the same direct, joint liability as the company. In practice the lender can claim from you as if you had borrowed the money yourself, as MJ Kotze Inc summarises.
Renunciation of the benefits of excussion and division
By default, South African law gives a surety two protections. The benefit of excussion requires the creditor to pursue the principal debtor first. The benefit of division limits each of several sureties to a proportionate share. Most deeds ask you to renounce both. Once renounced, the lender can come to you first, and for the full amount, even if other directors also signed.
Continuing or “covering” suretyship
Some deeds cover a single, defined loan. Many cover “all present and future debts” the company owes that lender, from any cause. That wording can bind you for facilities that do not exist yet, long after the loan you signed for is repaid. VDT Attorneys warns that such clauses can bind a surety for future debts indefinitely.
Limited or unlimited amount
A limited suretyship caps your exposure at a stated amount, usually the capital plus interest and costs. An unlimited suretyship has no cap. If the deed does not state a maximum, assume it is unlimited.
Certificate of balance and legal costs
Many deeds say a certificate signed by the lender’s manager is sufficient proof of the amount owed, which shifts the burden to you to disprove it. Many also make you liable for collection costs on the attorney and client scale, which is higher than the costs a court would ordinarily award. Neither is unusual, but both increase the amount at stake if things go wrong.
What happens if the business cannot pay?
If the company defaults and the deed makes you co-principal debtor with the benefits renounced, the lender can demand payment from you directly. If you do not pay, it can sue you, obtain judgment and execute against your personal assets. A judgment against you personally will also affect your own credit record.
Two situations surprise directors most:
- Liquidation. The company being wound up does not release you. The lender can claim from you without waiting for the liquidation to be finalised.
- Business rescue. Even where a business rescue plan reduces or discharges the company’s debt, sureties are not automatically released. In New Port Finance Co v Nedbank Ltd (2016), the Supreme Court of Appeal found that a deed of suretyship that preserves the creditor’s right to pursue the surety can override a compromise in the plan, as Cliffe Dekker Hofmeyr reports.
The best protection is not reaching that point. Knowing the warning signs of a cash flow problem and running the disciplines in our cash flow management guide give you time to act while options are still open. If repayments start to feel tight, speak to your lender early. A restructured payment plan is almost always better for a surety than a default.
Does the National Credit Act protect a surety?
Often, no. The National Credit Act applies to a suretyship (which it calls a credit guarantee) only to the extent that it applies to the underlying loan. The Act does not apply to credit agreements where the borrower is a juristic person, such as a company, with an asset value or annual turnover of R1 million or more. It also excludes large agreements of R250 000 or more with juristic persons, regardless of their size.
So if your company turns over more than R1 million, or borrows R250 000 or more, the loan is likely outside the Act, and your suretyship is outside it too. The courts confirmed this approach in FirstRand Bank Ltd v Carl Beck Estates, summarised by Moonstone. Your protection then comes from the terms of the deed and from ordinary contract law, which is why reading the deed matters.
Married in community of property? Your spouse may need to consent
Under section 15(2)(h) of the Matrimonial Property Act 88 of 1984, a spouse married in community of property may not bind themselves as surety without the written consent of the other spouse. Because the joint estate stands behind the suretyship, both spouses are affected.
There is an important exception. Section 15(6) removes the consent requirement where the suretyship is given in the ordinary course of the surety’s profession, trade or business. In Strydom v Engen Petroleum Ltd, the Supreme Court of Appeal applied an objective test to decide what that means, and Cliffe Dekker Hofmeyr notes that a director who signs suretyships for their own company as part of running it may fall within the exception. Do not assume that a missing spousal signature makes a suretyship unenforceable.
Can you get out of a suretyship?
It is harder to leave a suretyship than to sign one. The most common misunderstandings:
Resigning as a director does not end it. The suretyship is a contract between you and the lender. Your role at the company is not part of it.
Selling your shares does not end it. Make a written release from the lender a condition of any sale. The buyer or remaining directors may need to sign a replacement suretyship.
Notice usually ends future liability only. Where the deed allows you to withdraw, a notice given in line with the deed can end your liability for future debts. It does not release you from debts that already exist.
Repaying the debt ends it. For a suretyship tied to a single loan, settlement is the cleanest exit. Some lenders let you settle a business loan early without a penalty. If you move the debt elsewhere through refinancing a business loan, expect the new lender to ask for its own suretyship, and ask the old one for a written release.
If the business has more than one owner, agree in writing now what happens to each director’s suretyship if someone leaves, falls ill or dies. It belongs in your shareholders’ agreement and your business continuity plan.
Before you sign: eight questions to ask
- Is a suretyship required, and from whom? All directors, all shareholders, or only one?
- Is it limited to a maximum amount? If not, ask for a cap linked to the loan.
- Does it cover this loan only, or all present and future debts? Ask for it to be tied to the specific facility.
- Am I signing as co-principal debtor, and am I renouncing excussion and division? Understand that the lender can then come to you first.
- How and when does it end? On repayment, on notice, or on a written release?
- Does my spouse need to sign? Check your marital regime before the signing meeting.
- What costs can be claimed from me if the company defaults? Look for attorney and client scale costs.
- Can I realistically pay this if the business cannot? Borrow an amount the business can service in a slow month. Our guide to how much you can borrow sets out how lenders size a loan.
Strong applications have more room to negotiate. Our guides on how to get approved for a business loan and how to prepare your business for funding cover what lenders look for. Once you have signed, keep a copy of the deed with your loan documents, as covered in what to do after your loan is approved.

Frequently asked questions
What does it mean to sign surety for a business loan?
Signing surety means you personally promise the lender that you will pay the company’s loan if the company does not. In South Africa, most deeds of suretyship make the director liable as surety and co-principal debtor, so the lender can claim the full outstanding amount from the director directly.
Is a personal guarantee the same as a suretyship in South Africa?
Not exactly. A suretyship is an accessory obligation that depends on a valid underlying debt. A true guarantee is an independent obligation that can stand on its own. Lenders often use “personal guarantee” to describe what is legally a suretyship, so the wording of the document matters more than its title.
Does a suretyship have to be in writing?
Yes. Section 6 of the General Law Amendment Act 50 of 1956 provides that a suretyship is only valid if its terms are set out in a written document signed by or on behalf of the surety.
If I resign as a director, am I still liable as surety?
Usually, yes. A suretyship is a contract between you and the lender, and resigning as a director or selling your shares does not end it. You need a written release from the lender, or a notice that complies with the deed, which normally ends liability for future debts only.
Does my spouse have to consent if I sign surety?
If you are married in community of property, section 15(2)(h) of the Matrimonial Property Act requires your spouse’s written consent, unless the suretyship is given in the ordinary course of your profession, trade or business. Directors who sign for their own company may fall within that exception.
Does the National Credit Act apply to a director’s suretyship?
Only if the Act applies to the underlying loan. Loans to companies with an asset value or annual turnover of R1 million or more, and loans of R250 000 or more to any company, fall outside the Act, and so does the suretyship attached to them.
Can a lender claim from me as surety if my company goes into business rescue?
Yes, in many cases. A business rescue plan that reduces the company’s debt does not automatically release the sureties. The Supreme Court of Appeal found in New Port Finance Co v Nedbank Ltd that a deed which preserves the creditor’s right to pursue the surety can override a compromise in the plan.
Do I need to sign surety to get a business loan in South Africa?
It depends on the lender and the business. Banks and most alternative lenders ask the directors of a private company to sign surety, particularly where no asset is pledged or the business is young. Sole proprietors are not asked, because they are already personally liable for the debt. Ask before you apply, not when the pack arrives.
Can I get an unsecured business loan in South Africa with no personal guarantee?
Sometimes. Unsecured means no asset is pledged, not that no personal surety is required, and many unsecured lenders still ask directors to sign one. Ask the lender at the start whether a suretyship is required, whether it is capped, and whether it covers only that loan.
The bottom line
A deed of suretyship is not a formality. It decides whether your company’s debt can become your debt, how much of it, and for how long. Read it with the same care as the loan agreement, negotiate the scope and the cap where you can, and borrow an amount the business can repay without you.
