The Mortgagor’s surrender: understanding the cession of rights in mortgage bonds

Most people are familiar with the concept of transferring ownership of a tangible object– e.g., the sale of a car or home. But what happens when the subject of the transfer isn’t the object itself, but the right to that object? This is where the concept of cession comes into play. A cession agreement is a powerful legal mechanism that allows one person to transfer their personal right in an object to another, often as a means of securing the fulfilment of an obligation.

What is a cession agreement?

A cession agreement is a transfer agreement, which transfers personal rights from the current holder of the right (the cedent) to the prospective holder of the right (the cessionary). A cessation of rights does not happen in isolation but is based on an underlying obligatory agreement (the legal cause), which gives rise to the duty to transfer the right. In the context of property finance, the underlying cause is typically the mortgage bond.

Types & purpose of cession agreements

There are two main forms of cessions in South African law:

1. Out-and-out cession; and

2. Cession in securitatem debiti

Out-and-out cession (fiduciary security cession)

In an out-and-out cession, the cedent permanently and completely transfers their right to the cessionary. The cedent is fully divested of the right, which now vests in the cessionary who may enforce it freely. In certain cases, the parties may agree that the right be re-ceded when the debt is repaid. This agreement is described as a fiduciary security cession outlining the parties’ “pact of confidence.”

Cession in securitatem debiti

Cession in securitatem debiti (security cession) is a right that is transferred to secure the fulfilment of a debt. The effect being that the cedent is divested of the right to recover the ceded debt for as long as it remains the object of security, retaining only a “reversionary interest” therein. Upon the debt/obligation being satisfied, this right automatically reverts back to the cedent, and no additional agreement is needed to “re-cede” the right back to the cedent. This type of cession has been construed by our courts as being a pledge of a personal right.

Security cession in mortgage bonds

A mortgage bond secures a loan through the registration of a real right of security over immovable property in favour of the mortgagee (the bank). In a mortgage bond the mortgagor agrees to bind his/her immovable property as security for the fulfilment of obligations he/she has towards the mortgagee. The mortgagee is conferred with a real right of security against the immovable property, entitling them to foreclose on the mortgage bond, in the event that the mortgagor defaults.

Cession agreements have become somewhat standard in mortgage loan agreements, whereby the mortgagor surrenders and in so doing transfers certain rights, title and interest linked to the property to the mortgagee as “additional” security to secure his/her indebtedness.

Why use a security cession if a mortgage bond already secures the obligations of the mortgagor?

A bond vests the mortgagee with a real right of security against the immovable property of the mortgagor. A cession agreement may still be necessary because while a mortgage bond hypothecates immovable property as security, it does not secure the mortgagor’s personal rights (claims) to certain proceeds that arise from the property. These are intangible rights that cannot be hypothecated by mortgage but still holds commercial value, such as;

· Proceeds from any and all short-term and long-term insurance policies over the mortgaged property;

· rental income payable to the mortgagor (as landlord) under existing or future lease agreements;

· any other claims accruing to the mortgagor.

A security cession compliments the bond by transferring those personal rights to the mortgagee for the duration of the loan. This ensures that the bank’s security is comprehensive, covering not only physical property but also relates to claims and benefits in respect of the property.

Conclusion

A cession agreement constitutes a legal mechanism through which personal rights are transferred from the cedent to the cessionary. Whether in the form of an out-and-out cession or a cession in securitatem debiti, it’s purpose and legal effect arises from the underlying cause that justifies the transfer.

In the context of mortgage bonds, cession agreements serve an important supplementary purpose. Although a mortgage bond confers the mortgagee with a real right of security over immovable property, it does not extend to personal rights or incorporeal assets such as insurance proceeds, rental income, or other claims relating to the property. Therefore, in a mortgage bond, a cession in securitatem debiti ensures that these intangible assets are placed at the disposal of the mortgagee in the event of the mortgagor’s default.

Customary and Civil marriages are equal, says Constitutional Court

The Constitutional Court has recently delivered a significant judgment reaffirming that customary marriages and civil marriages hold equal legal status. Importantly, the Court clarified the implications and validity of antenuptial contracts within the context of customary marriages.

The recent judgment in Parch Properties 72 (Pty) Ltd v Summervale Lifestyle Estate Owner’s Association and Others 2026 (1) SA 449 (SCA) (17 October 2025) has brought welcome clarity to the long‑standing question of whether the Community Schemes Ombud Service Act 9 of 2011 (CSOS Act) limits the jurisdiction of the High Court.

Hurt feelings ≠ Constructive dismissal

Hurt feelings ≠ Constructive dismissal

Constructive dismissal was incorporated into South African labour law in the 1980s and later codified in the Labour Relations Act 66 of 1995 (“LRA”). In terms of section 186(1)(e) of the LRA, an employee may resign, whether with or without notice, and claim unfair dismissal on the basis that their continued employment had become intolerable. Although the concept can be difficult to apply in practice, the Constitutional Court has clarified its meaning and reaffirmed its role within our law.
