إذا أنكر من احتج عليه بالمحرَّر العادي خطه أو إمضاءه أو ختمه أو بصمته، أو أنكر ذلك خلفه أو نائبه أو نفى علمه به، وظل الخصم الآخر متمسكاً بالمحرَّر، وكان المحرَّر منتِجًا في النزاع، ولم تكف وقائع الدعوى ومستنداتها في إقناع المحكمة بصحة الخط أو الإمضاء أو الختم أو البصمة؛ فتأمر المحكمة بالتحقيق بالمضاهاة، أو بسماع الشهود أو بكليهما، وفقاً للقواعد والإجراءات المنصوص عليها في هذا النظام. ولا تسمع الشهادة إلا فيما يتعلق بإثبات حصول الكتابة أو الإمضاء أو الختم أو البصمة على المحرَّر.

Article 40 explained in plain English
After Article 39 made clear that the burden of proving that an ordinary document came from a person falls on the one who relies on it if the person against whom it is invoked denies it, this Article sets out when the court orders an investigation. This requires all of the following:
- The person against whom the ordinary document is invoked denies his handwriting, signature, seal or fingerprint, or his successor or representative denies this, or states that he has no knowledge of it.
- The other party continues to rely on the document.
- The document is material to the dispute, that is, it affects its determination.
- The facts and documents of the case are not sufficient to convince the court that the handwriting, signature, seal or fingerprint is genuine.
The court then orders an investigation by comparison, that is, comparing the denied handwriting or signature with established handwriting or a signature, or by hearing witnesses, or by both, in accordance with the rules and procedures set out in the Law.
The text limits the hearing of testimony here: it is heard only as to proving that the writing, signature, seal or fingerprint was placed on the document, not to prove the content of the transaction itself.
Article 41 regulates the hearing at which comparison documents and handwriting samples are submitted. A person facing a denial of a signature in his case is advised to consult a lawyer specializing in civil litigation.
Practical example
Majed submitted an ordinary paper in which a person acknowledges receiving an amount from him, and that person denied his signature. Majed continued to rely on the paper because it is decisive in the dispute, and the other documents were not enough to convince the court. The court orders the signature to be compared, or witnesses who were present at the signing to be heard, or both, and their testimony is limited to the fact that the signature was placed on the paper.

Frequently asked questions about Article 40 of the Saudi Law of Evidence
When does the court order a signature to be compared?
When the person against whom an ordinary document is invoked denies his signature, his opponent continues to rely on the document, it is material to the dispute, and the facts and documents of the case are not enough to convince the court that it is genuine.
Can a signature be proven by witnesses?
Yes. The investigation may be by hearing witnesses, by comparison, or by both, but testimony is heard only as to proving that the writing, signature, seal or fingerprint was placed on the document.
Does the court always order an investigation when there is a denial?
No. If the facts and documents of the case are enough to convince it that the handwriting, signature, seal or fingerprint is genuine, or if the document is not material, the conditions for ordering an investigation in the Article are not met.
