Using a guarantor (surety) for a home loan in South Africa
A guarantor — called a surety in South African law — signs a legal promise to repay the full outstanding bond if you stop paying. It can be the difference between an approval and a decline, but it puts the guarantor’s own finances and credit record on the line. It is a generous act that should never be entered into lightly — by either side.

- A guarantor is liable for the full outstanding bond on default — capital, interest, fees and legal costs.
- The surety can cut the guarantor’s own borrowing capacity and can harm their credit record if arrears occur.
- Banks assess the guarantor’s income, assets, credit record — and usually require independent legal advice.
- Alternatives — a co-applicant, a bigger deposit or a government subsidy — may achieve the same result with less risk to family.
This guide is general information for both the applicant and the person being asked to sign. It is not legal advice.
What suretyship actually means — in plain language
Under the General Law Amendment Act (suretyship provisions), a surety is a separate promise to answer for someone else’s debt.
When someone signs surety for your home loan, they are not merely vouching for your character. They are signing a contract with the bank under which they personally undertake to pay your debt if you do not. If you default on the bond, the bank can turn to the guarantor and claim the full outstanding amount — the unpaid capital, accrued interest, arrears, collection charges and the legal costs of recovering the debt.
This is the part that matters most, and it should never be softened: the guarantor’s own home, savings and income are the security. The bank does not have to exhaust every remedy against you first. In most surety agreements it can pursue the guarantor directly, and the guarantor’s liability typically mirrors everything you owe under the bond — not a capped portion of it, unless a cap is expressly negotiated and the bank agrees to it in writing.
Suretyship is common in South African credit practice and it is perfectly legal. Parents standing surety for a first bond, or a family member backing a borrower with a thin credit record, is a well-worn path. But “common” does not mean “harmless”. Every person asked to sign should understand that they are, in substance, taking on a second bond they hope never to have to pay.
The one-sentence version for the person being asked
If the borrower stops paying, the bank can claim everything owed from you — and that claim can survive your best intentions, your retirement, and in some cases your estate.
Guarantor vs co-applicant vs FLISP state guarantee
Search results mix these three up constantly. They are very different arrangements with very different consequences.
| Arrangement | Who owes the debt | Credit record impact | When it fits |
|---|---|---|---|
| Guarantor (surety) | The guarantor only steps in on default — but then owes the full outstanding amount. | Enquiry at signing; the debt’s payment history can affect them if arrears arise. | When the applicant is close to qualifying but the bank wants extra security. |
| Co-applicant | Both applicants own the obligation from day one, in defined shares or jointly. | The bond appears on both applicants’ records from the start. | When two people are genuinely buying together and both will live with the debt. |
| FLISP (state subsidy) | The state provides a subsidy to qualifying first-time buyers in a defined income band — it is not someone signing for your debt. | No surety is signed; the subsidy reduces the amount you need to borrow. | When you are a first-time buyer whose income falls within the qualifying band. |
The key distinction
A guarantor is a backstop — they hope never to pay. A co-applicant is a co-owner of the debt from the first instalment. A FLISP subsidy is neither: it is government assistance that lowers the loan amount for qualifying first-time buyers. If you are weighing up asking a parent to sign surety versus applying with your spouse as a co-applicant, the legal and credit consequences are completely different even though both can strengthen an application.
About FLISP, briefly
The Finance Linked Individual Subsidy Programme (FLISP, also called First Home Finance) is a government subsidy for qualifying first-time buyers in a defined income band. The subsidy amount depends on your income band, and the criteria are set by the Department of Human Settlements. Our first-time buyer grant guide explains the current criteria in plain language.
Who banks accept as a guarantor — and what they must prove
A guarantor is not a formality. The bank assesses them almost as thoroughly as it assesses you.
A demonstrable income and financial position
The guarantor must prove their own income and show the bank a financial position strong enough to carry the bond repayments on top of their existing commitments.
A healthy assets-versus-liabilities picture
Banks weigh what the guarantor owns against what they owe. A guarantor who is already fully extended on their own debt adds little security.
A clean or acceptable credit record
The guarantor’s own credit history is scrutinised. Adverse listings, judgments or high utilisation can disqualify them from the role entirely.
Independent legal advice before signing
A suretyship is a serious contract. Banks and good practice both expect the guarantor — who often has less information than the bank — to get independent legal advice on what they are signing.
Spousal consent in many cases
Because the surety can put the family’s shared estate at risk, banks frequently require the guarantor’s spouse to consent to the signing, and the Matrimonial Property Act can make this legally necessary too.
In practice, guarantors are most often parents or close family members of the buyer — people with an established income, built-up assets and an existing relationship with the borrower. A pensioner with a fixed income but substantial paid-off assets can be acceptable; a recent graduate with a good salary but no assets and high rent may not add the security the bank is looking for.
The independent-legal-advice point deserves emphasis. A suretyship is exactly the kind of contract where the signing party holds the least information and carries the largest potential loss. Any attorney — and any honest borrower — should insist that the guarantor takes the document to their own lawyer before signing, and if the guarantor is married, that the spouse is part of that conversation.
What signing surety actually costs the guarantor
There is no upfront fee — the cost is exposure. Here is where it lands.
Full exposure on default
If the borrower stops paying, the bank can call on the guarantor for the full outstanding amount — capital, interest, arrears, collection charges and legal costs. The guarantor’s own assets and income are the backstop.
Reduced own borrowing capacity
The contingent liability counts against the guarantor’s affordability. While the surety stands, the guarantor may qualify for less on their own bond, car finance or other credit.
Credit-record impact
If the bond goes into arrears, that adverse payment behaviour is reported and can damage the guarantor’s credit record too — even though the guarantor never drew a cent of the loan.
It survives until released
A suretyship usually lasts until the bond is repaid or the property is sold and the debt settled. Early release is the bank’s decision, not the guarantor’s, and it must be given in writing.
The reduced borrowing capacity point catches many guarantors off guard. Even while you pay perfectly, the contingent liability sits on the guarantor’s affordability calculation like a shadow bond. When they later apply for their own home loan, vehicle finance or a personal loan, the credit provider can factor in the amount they have committed to stand surety for — potentially reducing what they qualify for, or pricing their own credit worse.
And if the worst happens — the bond goes into arrears — the consequences arrive fast. The arrears are reported to the credit bureaus against the account, the guarantor’s record is damaged alongside the borrower’s, and the bank can issue summons for the full outstanding balance. For a parent in their sixties who signed to help a child into a first home, that can mean drawing on retirement capital at the worst possible time.

When a guarantor is the wrong tool — and better alternatives
Sometimes the kindest answer to “will you sign?” is a different plan entirely.
A guarantor is designed for one situation: the applicant is credible but the bank wants extra security — a young professional with strong income but a short credit history, for example. If the underlying problem is affordability, a guarantor is the wrong tool. Asking someone to guarantee a bond the borrower cannot realistically carry converts a lending problem into a family crisis.
Apply with a co-applicant
If two people are buying together, a joint application spreads the obligation openly rather than parking it on a third party. Both applicants share the benefit of the property and the burden of the debt from day one. Our bad-credit home loan guide covers how a co-applicant changes the assessment.
Save a bigger deposit
A larger deposit lowers the loan-to-value ratio, which reduces the bank’s risk without involving anyone else’s balance sheet. Six to twelve months of disciplined saving can move a borderline application into approval territory — use the affordability calculator to see how a deposit changes the price band you can shop in.
Check a government subsidy
Qualifying first-time buyers in the defined income band may be eligible for FLISP, which reduces the amount you need to borrow. Criteria and the subsidy amount are set by the Department of Human Settlements — see our first-time buyer grant guide for the current rules.
Strengthen the application itself
Paying down existing debt, correcting credit-report errors and waiting out a short employment history can all improve how a bank sees you — no guarantor required. Applying to multiple banks at once also matters: different lenders weigh the same profile differently, and a multi-bank application through a bond originator can surface an approval that makes surety unnecessary. Read bond originator vs bank for how that works.
Finally, there is the honest fallback: buy in a lower price band. A first home does not have to be the last home, and a bond the borrower can genuinely carry beats a bigger bond guaranteed by someone who cannot afford to honour it.
Before asking anyone to sign, it is worth checking what your own profile could support — see what you could qualify for first, so the surety question is answered with real numbers rather than hope.
How to ask someone — and what to put in writing
If you are going to ask, ask properly. Full disclosure is not optional.
The single most important thing you can do for the person you are asking is to tell them the whole truth about the exposure before they decide. That means sitting down and walking them through the numbers — the bond amount, the instalment, what happens on default — rather than presenting suretyship as a signature that will “never matter”.
- The guarantor’s maximum exposure: the full outstanding bond, interest, fees and legal costs — not a capped or partial amount.
- The trigger: the bank can call on the surety the moment the borrower defaults, without first exhausting action against the borrower.
- The timeline: the liability runs until the bond is repaid or the bank releases the guarantor in writing.
- What happens on death or insolvency: surety claims can be lodged against the guarantor’s estate, which is why estate planning with an attorney matters.
- A written family agreement between borrower and guarantor about how the borrower will keep the guarantor informed and what happens if payments are missed.
If someone asks you to sign surety, you are allowed — and expected — to slow the process down. Ask for a copy of the proposed surety agreement, take it to your own attorney, and have the conversation with your spouse before you sign anything.
Ask the bank or originator, in writing, what your total exposure would be on day one and what it could grow to over the life of the bond. Discuss the estate-planning implications — including what happens to the surety if you pass away before the bond is repaid — with your attorney. This page is general information, not legal advice; a one-hour consultation with an attorney who acts for you (not for the borrower and not for the bank) is the cheapest insurance you will ever buy.

Straight answers about home loan guarantors
Who can be a guarantor for a home loan in South Africa?
In practice, a guarantor is usually a close family member or someone with a strong financial position of their own — a stable income, manageable existing debt, and an acceptable credit record. The bank will assess the guarantor almost as rigorously as it assesses the applicant: their income, assets, liabilities and credit history all come under review. The guarantor must also have the legal capacity to sign, and banks often require the guarantor’s spouse to consent as well. Being willing is not enough — the bank decides whether the guarantor’s financial position actually adds security.
What banks accept guarantors for home loans?
Most major South African banks will consider a suretyship in the right circumstances, but none of them advertises guarantor acceptance as a standard product feature. Whether a guarantor helps depends on the bank’s credit policy, why the application is weak, and whether the guarantor’s own profile genuinely offsets that weakness. Some applications that a bank would decline even with a guarantor may be workable at another lender — which is one reason a multi-bank application through a bond originator can be worth exploring before anyone commits to signing surety.
Can a guarantor withdraw from surety?
Generally, no — not unilaterally, and not while the debt it secures is still outstanding. A suretyship is a binding contract that typically survives until the bond is fully repaid, the property is sold and the debt settled, or the bank formally releases the guarantor in writing. The bank is under no obligation to release a guarantor on request, because doing so removes the security it relied on. Anyone signing surety should assume from day one that they remain liable until the debt is gone — and should get their own attorney to explain the release conditions before signing.
Does being a guarantor affect my credit score?
Yes, it can. Signing surety usually involves the bank running a credit check on the guarantor, which leaves an enquiry on their record. More importantly, if the bond goes into arrears, that negative payment behaviour is reported against the debt — and because the guarantor is liable for it, it can damage the guarantor’s own credit record. The contingent liability also counts against the guarantor’s affordability when they later apply for credit themselves, even if the borrower has never missed a payment.
