Promissory Notes as Security: When Do They Become an Enforcement Risk?
A Legal Article from CounselO Legal
Supervised by Consultant / Omar Riyadh Baghdadi
A promissory note is one of the important commercial instruments used in transactions because of its evidentiary force in establishing an obligation and its enforceability when its statutory requirements are satisfied. However, using it as security in contractual relationships raises a precise question:
Does the promissory note remain independent of the relationship that gave rise to it in all circumstances, or can the end of that relationship or the determination of the actual indebtedness affect the legitimacy of retaining or using it?
This question is particularly important when the face value of the notes is significantly higher than the value of the actual obligation in dispute, or when several notes are issued to secure a single contract.
A Promissory Note Is Not Merely an Ordinary Security Document:
A promissory note is a commercial paper governed by the Commercial Papers Law. The law gives it legal effects that differ from those of an ordinary acknowledgment of debt.
The new Enforcement Law published on 1 May 2026 includes electronically registered bills and promissory notes in Article 7. Article 65 delays commencement until 180 days after publication; publication alone does not make that requirement operative. Umm Al-Qura: Enforcement Law, Articles 7 and 65.
Accordingly, signing a promissory note should not be viewed as a formal step merely intended to complete the contract. The consequences that may follow can be faster and more severe than the dispute concerning the contract itself.
Where Does the Problem Arise in Security Notes?
In many commercial relationships, one party is asked to issue one or more promissory notes to secure performance of its obligations.
The problem begins when a gap arises between:
The value of the security
and
The value of the actual obligation it is supposed to secure.
Part of the contract may end, some obligations may be settled, or the indebtedness may decrease, while the original notes remain with the beneficiary at their full value.
This creates genuine risks because the instrument originally issued to protect a specific contractual right may practically become an enforceable instrument exceeding the extent of that right.
Face Value Does Not Always Present the Full Picture of the Dispute
The existence of a particular amount written in the note is highly significant from a commercial perspective. However, in disputes involving security notes, it may be necessary to examine the broader picture:
What was the reason for issuing the note?
Which contract was connected to it?
Was the note issued against a due and specified debt, or as security for future obligations?
Has part of the obligation been performed?
Has part of the indebtedness been paid?
And has the relationship for which the note was issued as security ended?
These questions do not detract from the note’s nature as commercial paper, but they are highly important for understanding the legal risks arising when it is used within a complex contractual relationship.
Why Must the Actual Debt Be Determined?
One of the most important strategic tools in security-note disputes is to distinguish between two matters:
The existence of the note
and
The amount of the actual outstanding obligation between the parties.
If an actual debt exists, it must be determined through documents, calculations, invoices, and payment records.
Where certain amounts are disputed—such as a contractual penalty, fines, or damages for termination of the contract—including them in the amount intended to be secured or enforced may open a dispute extending beyond the mere existence of the note.
The objective is not to disregard the commercial paper, but to prevent confusion between its enforceability and whether the full amount is economically and contractually due under the underlying relationship.
The Risk of Duplicating Security
The risk increases when a new group of notes is issued in exchange for returning an earlier group, and both groups nevertheless remain with the other party.
In that situation, the face value of the security may be doubled without a corresponding increase in the debt.
Accordingly, one of the most important practical safeguards is:
If a replacement note is issued, the return of the previous note must be a clear and documented part of the replacement process.
Security should follow the obligation, not accumulate separately from it.
The End of the Contract Does Not Mean the Notes Can Be Ignored
Another mistake is to assume that the end of the contract automatically ends the effect of every note connected to it.
The matter requires more careful analysis.
Amounts may remain due and unsettled, and the basis for certain security may continue until the final account is determined.
At the same time, however, the end of the contract and the determination of the account between the parties raise a legitimate question:
What justification is there for continuing to retain security that exceeds the remaining obligation?
This highlights the importance of contractual provisions expressly regulating:
When the notes are delivered?
When are they returned?
What happens when the contract ends?
And is the note cancelled or its original returned after payment?
Enforcement May Precede Resolution of the Contractual Dispute
One of the most serious aspects of a promissory note is that a party may face enforcement proceedings while the underlying contractual dispute remains unresolved.
Before relying on an electronic-registration requirement, verify the law in force for the filing date, the implementing rules and any transitional provisions applicable to the instrument.
Therefore, management of a promissory-note matter should not begin only when enforcement occurs.
It should begin when the contract is signed.
How Should Contractual Promissory-Note Risks Be Managed?
The best approach is not always to avoid promissory notes. They may be a legitimate and useful tool for protecting rights.
Their use must, however, be controlled.
The contract should clearly specify:
The reason for issuing the note.
The obligation it secures.
The value or the mechanism for determining it.
When the note may be used.
When it must be returned or cancelled.
How it will be handled upon partial payment.
What happens upon termination of the contract or replacement of the note.
That more than one security for the same obligation will not be retained without clear justification.
These details may seem secondary at signing, but they may become the essence of the dispute upon enforcement.
CounselO Legal’s Approach to Analyzing Security Notes
At CounselO Legal, we do not begin examining these matters by asking:
Is there a promissory note?
Instead, we ask a connected series of questions:
What is the reason for the note? → What obligation does it secure? → What is the actual amount of the debt? → Has the basis of the security ended or changed? → Is the value of the note proportionate to the obligation? → Is there a risk of enforcement exceeding the indebtedness? → What is the most appropriate course for protecting the legal position?
This methodology is important because a dispute may appear on its face to concern commercial paper, while the real decisive issue lies in the contract, the accounts, and the nature of the security.
Conclusion
A promissory note is a powerful instrument, and that power is precisely what makes its use require greater care.
The risk does not lie in the note itself, but in the possibility that the amount written in it becomes disconnected from the actual obligation for which it was issued.
Accordingly, the most important question before signing a promissory note as security is not:
Can the other party enforce it?
It is:
What will happen to this note when the obligation it was issued to secure changes or ends, the contract terminates, or the debt is paid?
If the contract does not clearly answer this question, the protective measure may become an independent source of dispute.

The most important observation from the previous work: The case practically studied by CounselO Legal confirms the value of this analysis. The core of the strategy was to distinguish between the face value of the notes and the actual indebtedness arising from the contract, and then address the effect of that distinction on continued retention of the notes.
