Forensic examination vs. expert study: what is the difference

A forensic examination and an expert study are often carried out by the same specialist, using the same methodologies — yet they are different procedural instruments with different evidentiary weight. A forensic examination (sudova ekspertyza) is ordered by a court, an investigator or an investigating judge within an existing case; an expert, out-of-court study (ekspertne doslidzhennia) is conducted at the request of an individual, a company or a lawyer, outside any proceedings. Confusing the two costs parties time and money: they commission the wrong thing, or expect a document to carry weight it simply does not have. Below is when each form is appropriate, how a private opinion can be brought into a case as evidence, and why a court may still order a repeat examination.

One qualification — two procedures

Both forms rest on the same specialist statute — the Law of Ukraine “On Forensic Expert Activity” — and are elaborated by the Instruction on ordering and conducting forensic examinations and expert studies, approved by Order of the Ministry of Justice of Ukraine No. 53/5. In other words, the expert, the methodologies, the register of certified forensic experts and the laboratory base are identical. The difference lies not in the depth of analysis, but in two things: the legal basis on which the work is ordered, and the procedural status the finished document will carry.

For economic questions — debt, losses, the correctness of accruals, the movement of funds, signs of asset stripping — this is especially sensitive: the form determines whether your opinion becomes full-fledged evidence or merely an argument for negotiations.

Forensic examination: ordered by the court or the investigation

A forensic examination is conducted only on the basis of a procedural document:

• a court ruling (in civil, commercial or administrative proceedings);
• an order of the investigator or prosecutor, or a ruling of the investigating judge (in criminal proceedings).

Key features:

• it exists inside open proceedings — it cannot be ordered without a case or criminal proceedings;
• before starting work, the expert is warned of criminal liability for a knowingly false opinion (Article 384 of the Criminal Code of Ukraine, KK) and for refusing to perform assigned duties (Article 385 of the KK). This warning is recorded in the opening part of the opinion;
• the result is formalised as an expert opinion (of a forensic examination) — a procedural source of evidence.

In criminal proceedings of an economic nature, such an order is usually issued by an investigator of the Bureau of Economic Security of Ukraine (BEB) or by a prosecutor, and the study is often prompted by materials from inspections by the State Tax Service or the State Financial Monitoring Service. It is precisely the warning of liability that gives the document its particular weight: the expert is personally answerable before the law for the accuracy of the conclusions.

Expert (out-of-court) study: commissioned by a party

An expert study is conducted at the request (application or letter) of a citizen, a company or a lawyer — outside the court process and without a ruling or order.

Key features:

• the basis is a contract and the client’s application, not a procedural document;
• the expert is not warned of liability under Articles 384 and 385 of the KK (there are no proceedings within which such a warning would operate);
• the result is formalised as an expert study opinion.

Importantly: in content, scope and methodology such a study may be in no way inferior to a forensic examination. The difference is in procedural status, not in the quality of the analysis.

A quick comparison

Criterion	Forensic examination	Expert study
Basis	Court ruling / order of investigator, prosecutor, investigating judge	Application (request) of a person, company or lawyer
Timing	Within an open case or proceedings	Before trial or in parallel, outside the process
Warning under Articles 384, 385 of the KK	Yes	No
Name of the document	Expert opinion (of a forensic examination)	Expert study opinion
Status in court	Procedural source of evidence	Written evidence assessed by the court
Typical use	Proving facts in a case	Assessing prospects, preparing a position

Evidentiary weight: the key difference

A court has no “evidence of pre-established weight” — it assesses each piece of evidence according to its own inner conviction. But the procedural status of a document affects how it is perceived.

• A forensic examination opinion is added to the file as a full expert opinion. It can be challenged, but by default it carries the weight of procedural evidence.
• An out-of-court study opinion is not, in itself, an “expert opinion” in the procedural sense. It is added as written evidence: the court takes it into account, but may also order its own examination.

An in-between form: an expert opinion commissioned by a party

The procedural codes provide a separate, often underrated mechanism — a party engages an expert itself, already for the case:

• in commercial proceedings — an examination commissioned by a participant (Article 101 of the Commercial Procedure Code, GPK);
• in civil proceedings — a similar procedure (Article 106 of the Civil Procedure Code, TsPK);
• in administrative proceedings — an examination commissioned by a participant (Article 104 of the Code of Administrative Procedure, KAS);
• in criminal proceedings — the right of a party (in particular, the defence) to engage an expert independently (Article 243 of the Criminal Procedure Code, KPK).

In this format the expert is warned of liability under Articles 384 and 385 of the KK, and the document has the status of an expert opinion, not merely an out-of-court study. In practice this is the “golden mean”: the party keeps the initiative and the speed, yet obtains a document of higher evidentiary weight. For civil and commercial disputes this is often the optimal route.

When an out-of-court study is the right choice

An out-of-court study is a tool of strategy and preparation, not of proof itself. It is worth commissioning when you need to:

• assess the prospects of a dispute before going to court — whether there is an economic basis for a claim or for objections, and the likely size of the claims;
• prepare a legal position and substantiate a lawyer’s request or a motion;
• conduct pre-trial settlement — negotiations, claim work, mediation, where the parties need an independent figure;
• make a management decision — a director or owner needs to understand the real situation before spending time and money on litigation;
• check an opponent’s opinion before the hearing, in order to prepare questions for the expert.

In my expert practice, an economic study at an early stage often changes the strategy itself: sometimes it shows that a claim is hopeless and the client saves on court costs, and sometimes the reverse — it reveals grounds for claims the party never suspected.

How to bring a private study into a case

An out-of-court opinion does not automatically “turn into” a forensic examination, but it works within the process as follows:

1. Submit it as written evidence — attach it to the claim, the response or the motion, together with the documents it is based on.
2. File a motion to order a forensic examination, framing the same or refined questions. A ready study helps to pose the questions to the expert correctly.
3. Use it for questioning or explanations — on its basis you can put reasoned questions to the court expert or to the opponent’s specialist.
4. For civil, commercial and administrative cases, consider the format of Article 106 of the TsPK / Article 101 of the GPK / Article 104 of the KAS — engagement of an expert by a party, with a warning of liability, which immediately confers a higher status.

The risk of a repeat or additional examination

Even a persuasive private opinion does not deprive the court of the right to order its own (including a repeat or additional) examination — for example, when the opponent challenges the methodology or the expert’s independence. An out-of-court study should therefore be seen as the foundation of a position, not a guarantee of the outcome. When the stakes are high, it is sensible to plan from the outset for a transition to a forensic examination or to the party-engagement format.

Common mistakes

• Confusing the names. An “expert study opinion” and a “forensic expert’s opinion” are different documents; in motions they should be named precisely.
• Expecting the weight of a verdict from an out-of-court opinion. It is a strong argument, but the court will still weigh it together with the other evidence.
• Posing incorrect or overly broad questions. Vague questions devalue even quality analysis; they must be specific and within the competence of an economic examination.
• Failing to provide primary documents. Without a complete package (contracts, accounting registers, bank statements) the opinion will be limited by caveats.
• Losing time. An early study saves money; one commissioned “on the doorstep” of the hearing often no longer manages to influence the strategy.

A quick decision algorithm

1. No case yet? Start with an expert study — assess the prospects and the sums.
2. Preparing a claim or a defence and want a higher status? Consider engaging an expert as a party (Article 106 of the TsPK, Article 101 of the GPK, Article 104 of the KAS, Article 243 of the KPK).
3. The case is already in court and the question is complex or disputed? Move to order a forensic examination.
4. The opponent has filed its own opinion? Commission a review of the methodology and prepare questions for the expert.

The right choice of form saves both time and money: sometimes an out-of-court study is enough, and sometimes only a forensic examination will provide the evidence needed.
