What is this article about?
Conflicts in the purchase of industrial machinery are not uncommon in the mechanical and plant engineering industry. A machinery dispute between buyer and supplier is time-consuming and costly. The causes range from unclear requirements and inadequate technical specifications to complex communication errors between the machine buyer and the machine manufacturer. This article demonstrates how structured mechanical engineering dispute resolution with the help of forensic machinery experts can help avoid or efficiently resolve disputes.

Typical conflict triggers when purchasing machinery lead to “machine dispute buyer supplier”
A machinery dispute between buyer and supplier often arises when the expectations of both parties are not aligned. Missing or inaccurate specifications, undocumented changes, or poor communication lead to misunderstandings that later result in a complaint about industrial machinery defects.

The first escalation often occurs shortly after delivery when the buyer files a defect notification pursuant to Section 377 of the German Civil Code (BGB). Assessing whether the issues raised constitute a defect or a malfunction of the machine, or whether everything was delivered as agreed, is usually impossible without technical expertise.
The role of technical specification testing machines
The Technical Specification Review for Machines is the central step in any dispute. The question is always:
What was ordered? What was delivered?
This simple formula is often difficult to answer in practice due to unclear agreements, missing technical definitions or non-transparent communication channels.
A precise review of the agreement between the manufacturer and the buyer forms the basis for the legal and technical assessment. This quickly reveals whether there is a technical error or whether the delivery is in compliance with the contract.
The forensic machine expert as a key figure / securing evidence in machine conflict
An experienced forensic machine expert possesses the necessary expertise and methodological competence to document technical deviations objectively and factually. During the on-site inspection, the machine is examined on-site and compared with the agreed specifications. The results are compiled into an evidentiary report, which serves as the basis for the legal process.
Preserving evidence in machinery disputes includes technical data, photos, documentation, drawings, complaint correspondence, and other relevant information that enables traceability. The goal is:
Create clarity!
Legal significance of the report: expert evidence
Expert evidence is a central element in legal disputes involving machinery buyers and suppliers. Only with a sound technical report can a lawyer work effectively in a machinery buyer-supplier dispute. The legal qualification of a “defect” is based on the identified technical error.

The machine manufacturer’s warranty obligations and the rights of the machine buyer are assessed based on these facts.
The dynamics of typical disputes
Typical conflicts often occur in several phases:
- The buyer observes problems and reports them.
- The manufacturer denies that there is a defect.
- The buyer refuses to make the final payment.
- Threats, pressure and escalation follow.
At this point, a machine expert should be consulted. Unfortunately, this often happens too late, when the original condition of the machine has already been altered (e.g., through attempts at repair).
Early commissioning is crucial for the probative value.
Minimizing risks when purchasing machinery: Prevention instead of arguing
Prevention is the best protection against a costly machinery dispute between buyer and supplier. As part of professional plant engineering conflict management, it is advisable to:
- to clearly formulate specifications and requirements ,
- to design contract contents in detail,
- to record all technical requirements in writing,
- To document changes externally in a comprehensible manner
For this reason, it’s worthwhile to collaborate with experienced forensic machine experts early in the planning phase. This helps avoid misunderstandings and unclear wording.
Consequences of unresolved conflicts for industrial companies
Unresolved machine conflicts have a direct impact on production, finances, and reputation. Such conflicts can lead to downtime, delivery delays, and penalties. In addition, they can cause reputational damage and customer dissatisfaction.
A factually sound clarification by a neutral expert with experience in this tense environment helps to limit consequential damage and create certainty of action.
Conclusion
A “buyer-supplier machinery dispute” is complex, technically demanding, and often has serious legal consequences. Only with a clear technical basis – presented by a forensic expert report – can misunderstandings be clarified, rights secured , and conflicts resolved in machinery disputes.
Industrial companies, production managers, and purchasing managers are well advised to immediately consult a forensic machine expert upon the first complaint regarding a defect in an industrial machine and to consult a specialized lawyer promptly. Machine experts with experience in litigation can certainly recommend several lawyers with whom they have successfully handled numerous legal disputes for their own clients.
