A suretyship can make you personally liable for someone else’s debt, often without a limit and without an easy exit. These obligations don’t always end when the underlying contract does. They can outlive the sale of a business or even a change in your role at the company. Before signing, you need to know exactly what it covers and how you can escape it.
Why This Keeps Coming Up
Banking law rarely makes headlines, until a director receives a letter of demand for a debt they thought was long behind them. We’re seeing more disputes tied to suretyships, personal guarantees, and credit agreements. The agreements themselves are usually watertight. The real issue? The person signing didn’t fully grasp how far their liability stretched, or how long it would last.
What Is a Suretyship?
A suretyship is a contract in which one person (the surety) agrees to take responsibility for the debt of another person or entity (the principal debtor) if that debtor fails to pay. In South Africa, the General Law Amendment Act 50 of 1956 requires that suretyships be in writing and signed by or on behalf of the surety to be enforceable.
Once signed, the surety’s liability is not simply tied to the underlying loan agreement. In several important respects, it stands on its own. That means it can survive the end of the contract that created it, the sale of the business, or even a change in your role within the company.
Five Risks Directors Consistently Underestimate
1. Liability can outlive the business relationship
A suretyship doesn't automatically fall away when:
• the underlying contract is cancelled
• the company is deregistered or dissolved
• you resign as director or sell your shareholding
• the business itself is sold to a new owner
Unless the suretyship is explicitly revoked in writing and the lender confirms the release, your personal exposure continues. Resigning as a director does not cancel a suretyship you signed personally.
2. "Unlimited" liability has no ceiling
Many suretyships are drafted as "unlimited" or "continuing" suretyships. This means the surety covers not just the current loan, but any future debt the principal debtor incurs with that lender, with no maximum amount specified.
A single clause like this can tie your personal assets, including your house, your savings, and your other investments, to a company's total exposure to a bank, not just the amount you had in mind when you signed.
3. Loan agreements often contain acceleration clauses
Many credit agreements let the lender demand full repayment immediately if certain trigger events occur. These can include:
• a missed payment on the facility itself
• a breach of a separate, unrelated agreement with the same lender
• tax non-compliance
• a restructuring or change-of-control event
These clauses mean a business can face a full repayment demand even while it's managing temporary cash flow pressure, and not necessarily heading toward default.
4. Cross-suretyships can link you to debts you've never seen
If you sit on the board of more than one company in a group, or if your company has related entities, a suretyship you sign may cover the obligations of the whole group, not just the entity you're most familiar with. Read the definition of "principal debtor" in the document carefully. It's often broader than the name on the loan application.
5. Restructured facilities don't automatically release old security
When a business renegotiates a facility, like new terms, a new repayment schedule, or a different type of loan, it's a common assumption that the new agreement replaces the old one and the old security falls away. It doesn't, unless the release is negotiated and recorded in writing as part of the restructuring. Without that, you can end up as surety on both the old and new facilities at once.
Why This Matters for Directors Right Now
Company directors owe duties to act in the best interests of the company under the Companies Act 71 of 2008, but a personal suretyship sits outside that framework entirely. It's a private contract between you and the lender. The company's protections don't extend to you as an individual surety.
If your company also holds assets in a trust structure, it's worth checking how those assets are treated under the Trust Property Control Act 57 of 1988 before offering anything as security, since trust assets are subject to their own rules around disposal and encumbrance.
Practical steps worth taking before signing anything:
• Ask whether the suretyship is limited or unlimited and get the limit in writing if there is one.
• Ask what happens to the suretyship if you leave the company or sell your shares.
• Check whether the agreement covers only the current facility or "all present and future debts."
• Get confirmation in writing when a facility is restructured that any prior suretyship is either carried forward or released. Don't assume either way.
• Keep a personal file of every suretyship you've signed, since these documents are easy to forget about once the original loan is settled.
Conclusion
A suretyship is one of the few documents where the consequences of not reading the fine print fall on you personally, and not on the company. The lender has drafted the agreement to protect its position. Getting proper legal advice before you sign protects yours.
WRI's banking and finance team reviews suretyships, guarantees, and credit agreements before you commit to them, and can help negotiate limits, releases, and exit terms where the lender's draft doesn't include them.

Frequently Asked Questions
1. Can a suretyship be cancelled at any time?
Not unilaterally in most cases. Continuing suretyships typically require written notice to the lender, and the lender may still hold you liable for debts incurred before the cancellation takes effect.
2. Does resigning as a director cancel my personal suretyship?
No. A suretyship is a personal contract with the lender, separate from your position at the company. Resigning doesn't release you from it.
3. What's the difference between a limited and unlimited suretyship?
A limited suretyship caps your liability at a stated amount. An unlimited suretyship covers the full debt, including future borrowing, with no cap unless one is negotiated.
4. Does a new loan agreement replace an old suretyship?
Not automatically. Unless the lender explicitly releases the old suretyship in writing as part of the restructuring, it can remain in force alongside the new agreement.
5. Can a suretyship cover debts of a company I'm not a director of?
Yes, if the document names that company (or a group of companies) as a principal debtor, or if you're a surety for a group facility. Always check exactly who is covered before signing.
