Notarial Bonds vs Cession vs Mortgage Bond in South Africa: When to Use Each

When structuring security for a lending or commercial transaction, one of the first questions is not whether security is needed, but which form of security is most appropriate.

In South Africa, three of the most commonly used security instruments are mortgage bonds, notarial bonds and cessions in security. They do different jobs.

A mortgage bond is generally used over immovable property, a notarial bond is used over movable property and a cession in security is commonly used over personal rights and incorporeal assets, such as book debts, insurance claims, lease rights or contract proceeds.

Choosing the wrong instrument can leave a creditor under-secured, delay enforcement or create avoidable disputes when the borrower defaults.

Mortgage bonds: best for immovable property

A mortgage bond is usually the correct form of security where the asset is land or immovable property, including commercial property, residential property or agricultural land. Mortgage bonds are registered in the Deeds Office and South Africa’s deeds registration system records mortgages and other rights relating to immovable property.

A mortgage bond is generally the right choice where:

• the borrower owns immovable property

• the lender wants strong real security over that property

• the transaction is a property-backed loan, development facility or traditional home loan

• the parties want a well-established enforcement route tied to immovable property security

Use a mortgage bond when the value sits in the land or building itself.

Typical examples include:

• a bank funding the purchase of a warehouse

• a development lender funding a commercial property project

• a homeowner granting security over a house for a home loan

Notarial bonds: best for movable assets

A notarial bond is used where the security asset is movable property rather than land. The Security by Means of Movable Property Act 57 of 1993 regulates the legal consequences of registering a notarial bond over specified movable property.

This makes notarial bonds especially useful where the lender is taking security over assets such as:

• plant and machinery

• vehicles and fleets

• manufacturing equipment

• inventory or stock

• other movable business assets

There are two broad categories to keep in mind.

Special notarial bonds

A special notarial bond is usually used where the secured movable assets can be specifically identified and described. Under the Security by Means of Movable Property Act, a registered bond over specified movable property is deemed to have been delivered, which gives the creditor stronger security without taking physical possession.

A special notarial bond is often appropriate where:

• the lender is financing clearly identified equipment

• the borrower needs to keep using the asset in its business

• the parties want stronger security over a defined movable asset pool

In practice, this works well in asset finance and equipment-backed lending.

General notarial bonds

A general notarial bond is broader. It is commonly used where the lender wants security over the debtor’s movable property generally, rather than over a tightly identified list of assets. But a general notarial bond does not give the same immediate protection as a special notarial bond. A bondholder under a general notarial bond generally obtains a real security right enforceable against third parties only once the bond is perfected, usually by taking possession pursuant to the bond terms and, where necessary, court process.

A general notarial bond is often used where:

• the lender wants wider movable-asset coverage

• the asset base changes over time

• the parties want additional security alongside other instruments

• the creditor is prepared to perfect if default occurs

Use a notarial bond when the real value lies in movable assets rather than land.

Cession in security: best for rights, claims and receivables

A cession in security is usually used where the asset being secured is not a physical thing, but a right. South African law recognises cession as the transfer of rights by agreement, and security cessions are commonly used to secure debts. Authorities also distinguish between an outright cession and a cession in securitatem debiti, which is a cession given as security.

A cession in security is commonly used for:

• book debts

• rights under contracts

• lease receivables

• insurance proceeds

• loan account claims

• other incorporeal rights

This is often the right instrument where the lender wants access to a borrower’s cashflow stream or contractual rights rather than its land or physical equipment.

Typical examples include:

• cession of rental income under a long lease

• cession of book debts in a working capital facility

• cession of insurance proceeds in a finance transaction

• cession of rights under material commercial contracts

Use cession when the asset is a right, receivable or claim rather than tangible property.

So when should each be used?

The answer usually depends on what asset class is actually carrying the value in the deal.

Use a mortgage bond when:

• the borrower has valuable immovable property

• the lender wants fixed-property security

• the deal is property finance, development finance or a conventional real estate-backed facility

Use a notarial bond when:

• the security asset is movable property

• the lender is funding equipment, machinery, stock or business assets

• the borrower must retain possession and continue trading with the assets

• a special bond can be used over specifically identified assets, or a general bond can supplement the security package

Use cession in security when:

• the borrower’s strongest assets are receivables or contractual rights

• the lender wants security over cashflows

• the transaction involves lease rights, insurance claims, book debts or other incorporeal assets

In many transactions, the right answer is not one instrument — it is a security package

In commercial lending, these instruments are often used together, not as alternatives. A lender might take:

• a mortgage bond over immovable property

• a special notarial bond over key equipment

• a general notarial bond over the wider movable asset base

• a cession in security over receivables, insurance proceeds and material contracts

That kind of layered structure is often used because different asset classes require different security mechanisms. A single instrument will not always give adequate coverage across land, movables and incorporeal rights.

Common mistakes to avoid

A few issues come up repeatedly in practice.

• Using a notarial bond where a cession is actually needed

If the real value sits in receivables, lease income or contractual claims, a notarial bond may not address the most important asset.

• Using a cession where tangible asset security is required

If the lender needs security over machinery, vehicles or stock, cession alone may be inadequate because those assets are movable property, not merely rights.

• Treating special and general notarial bonds as interchangeable

They are not. A special notarial bond over specifically described movable property can operate far more strongly than a general notarial bond that still requires perfection.

• Failing to describe movable assets properly

Where a special notarial bond is intended, the asset description matters. If the assets are not properly specified, the creditor may lose the benefit of the stronger statutory protection contemplated by the Security by Means of Movable Property Act.

• Leaving security structuring too late

Where multiple assets are involved, security should be planned at the start of the transaction, not after default risk emerges.

A practical rule of thumb

A simple way to think about it is this:

• land and buildings = mortgage bond

• equipment, vehicles, machinery, stock and other movables = notarial bond

• receivables, lease rights, insurance claims and other personal rights = cession in security

But in larger transactions, the best answer is often a combination of all three.

How we assist

We advise lenders, businesses and deal teams on the structuring, drafting and registration of security packages, including:

• mortgage bonds over immovable property

• special and general notarial bonds over movable assets

• cessions in security over receivables and contractual rights

• integrated security structures for commercial lending and asset finance transactions

The right security instrument depends on the asset, the transaction structure and the enforcement objective. Getting that right upfront can make a significant difference when enforcement later becomes necessary.
