Civil Law and UAE — Ultra-Short Evidence Law Points

1. Meaning of Evidence

Evidence = material used to prove or disprove facts before a court.

Basic formula:

Fact → Evidence → Proof → Judicial Finding

The current federal framework is principally the Federal Decree-Law No. 35 of 2022 on Evidence in Civil and Commercial Transactions.

2. Ultra-Short Evidence Rules

3. Burden of Proof

The most important rule:

“He who asserts must prove.”

A claimant normally has to establish the factual foundation of the claim.

Example:

A says: “B owes me AED 500,000.”

A should establish:

existence of the obligation;

amount;

maturity;

relevant agreement/transaction;

non-payment.

A mere allegation is not proof.

4. Standard of Proof

In civil litigation, the court assesses whether the evidence establishes the relevant facts according to the applicable civil standard.

In Graciela Limited v Giacobbe [2014] DIFC CFI 027, the DIFC Court expressly applied the balance of probabilities standard. The Court relied heavily on circumstantial, documentary and expert evidence in determining responsibility for an IT-system attack. (DIFC Courts)

Memory

More likely than not + reliable evidence = civil proof.

Serious allegations do not automatically create a separate higher legal standard, although the seriousness and inherent probability of an allegation affect how the evidence is evaluated. (DIFC Courts)

5. Documentary Evidence

Important examples:

contracts;

invoices;

receipts;

bank records;

emails;

correspondence;

company records;

accounting records;

technical reports;

photographs;

electronic records.

Golden rule

Document + authenticity + relevance + reliability = evidential value

6. Electronic Evidence

Modern UAE litigation increasingly involves:

emails;

WhatsApp/business messages;

electronic signatures;

databases;

server logs;

metadata;

digital photographs;

blockchain records;

electronic invoices;

cloud records.

The key questions are:

Who created it?
Has it been altered?
When was it created?
How was it stored?
Does it relate to the disputed fact?

7. Expert Evidence

Experts are particularly important in:

construction;

accounting;

valuation;

engineering;

IT;

cybersecurity;

medical issues;

financial calculations.

An expert assists the court; the expert does not normally replace the judge's legal decision-making function.

In Mahuta v Manwari [2023] DIFC CFI 023, the Court considered objections concerning an expert report, including alleged methodological shortcomings and failure to address evidence. The Court noted that the parties had been given the opportunity to provide material to the expert and ultimately accepted the expert's assessment. (DIFC Courts)

8. Expert Cannot Decide the Law

An important distinction:

Expert = technical assistance
Judge = legal determination

In Graciela v Giacobbe, the Court expressly stated that the ultimate question was for the Court rather than the expert to decide, even though expert evidence was important in establishing the technical facts surrounding the cyberattack. (DIFC Courts)

9. Preservation of Evidence

Evidence may deteriorate or disappear.

Therefore, courts can have procedures for:

inspection;

preservation;

expert appointment;

recording the condition of property;

preserving technical evidence.

In Brookfield Multiplex Constructions LLC v DIFC Investments LLC [2016] DIFC CFI 020, the DIFC Court discussed the use of expert inspection to preserve evidence where evidence concerning defects could otherwise be lost. The Court distinguished preservation of evidence from determination of substantive liability. (DIFC Courts)

Memory

Preserve evidence ≠ decide liability.

10. Circumstantial Evidence

Evidence does not always have to be direct.

Example:

There is no eyewitness to a cyberattack, but:

server logs;

access records;

passwords;

IP information;

timing;

deleted files;

expert forensic analysis

may collectively prove responsibility.

Graciela v Giacobbe is a strong illustration. The Court found responsibility on the basis of a combination of circumstantial, factual and expert evidence. (DIFC Courts)

11. Foreign / Non-DIFC UAE Law as Evidence

In Fidel v Felecia & Faraz [2015] DIFC CA 002, the DIFC Court of Appeal held that DIFC Courts are not automatically bound to require expert evidence simply because non-DIFC UAE law is involved. The Court has discretion concerning evidential rules, taking account of the circumstances and judicial expertise. (DIFC Courts)

Memory

Foreign law does not automatically = expert witness.

12. Evidence and Arbitration

Evidence may also be preserved before or alongside arbitration.

Brookfield Multiplex is particularly useful because the Court considered whether an expert could inspect and preserve evidence despite an arbitration agreement. The Court recognised the distinction between preserving evidence and deciding the underlying contractual liability. (DIFC Courts)

13. Evidence and Damages

For a damages claim, evidence should establish:

Entitlement → Causation → Quantum

Example:

Claimant says:

“The defendant's breach caused AED 2 million loss.”

The claimant should establish:

breach;

causal connection;

actual loss;

calculation of AED 2 million;

supporting documents/expert evidence.

14. Six+ Important Case Laws

1. Graciela Limited v Giacobbe [2014] DIFC CFI 027

Principle: Balance of probabilities; circumstantial evidence can be powerful; expert evidence may establish technical facts, while the ultimate legal determination remains with the Court. (DIFC Courts)

2. Mahuta v Manwari [2023] DIFC CFI 023

Principle: Expert methodology and treatment of documentary evidence are relevant to the weight given to an expert report. (DIFC Courts)

3. Brookfield Multiplex Constructions LLC v DIFC Investments LLC [2016] DIFC CFI 020

Principle: Court-appointed expert inspection can preserve evidence without deciding the substantive liability that belongs to the trial court or arbitral tribunal. (DIFC Courts)

4. Fidel v Felecia & Faraz [2015] DIFC CA 002

Principle: Expert evidence concerning non-DIFC UAE law is not automatically mandatory; the DIFC Court has evidential discretion. (DIFC Courts)

5. Taaleem PJSC v National Bonds Corporation PJSC & Deyaar Development PJSC [2010] DIFC CFI 014

Principle: The case is important for the DIFC approach to expert evidence concerning non-DIFC UAE law, particularly where the judge's legal background is relevant.

6. Dubai Court of Cassation Judgment No. 402 of 2020

Principle: Burden of proof, expert evidence and causation are matters that the court evaluates on the evidentiary record.

7. Dubai Commercial Cassation No. 767 of 2021

Principle: Expert evidence is assessed by the court and does not automatically determine the dispute.

8. Dubai Commercial Cassation Nos. 1012 and 1023 of 2022

Principle: An expert's function is limited by the expert mandate; technical opinion does not substitute for the court's legal determination.

15. Evidence vs Proof

Memory

Evidence is the material; proof is the persuasive result.

16. Evidence Revision Formula

B-R-A-W-E

B — Burden
R — Relevance
A — Authenticity
W — Weight
E — Expert/electronic evidence

For damages:

Claim → Evidence → Causation → Quantum → Remedy

For digital evidence:

Source → Attribution → Integrity → Relevance → Weight

Ultra-Short Exam Answer

UAE evidence law regulates how parties establish disputed facts in civil and commercial proceedings. The principal concepts are burden of proof, relevance, authenticity, documentary and electronic evidence, witness testimony, expert evidence, inspection, preservation and judicial evaluation of evidential weight. The claimant generally bears the burden of establishing the facts supporting the claim. Expert evidence assists the court on technical matters but does not replace the court's legal judgment. Modern disputes increasingly require reliable electronic and forensic evidence.
