- Prevents the transfer of contractual rights without express consent
- Protects against unwanted changes to the contractual partnership
- Particularly relevant for critical suppliers and sensitive services
- Can be agreed both unilaterally and bilaterally
- Requires clear wording for legally secure enforcement
Contents
Definition: Prohibition of assignment
A prohibition of assignment regulates the transferability of contractual rights and obligations between the parties.
Legal basis
The prohibition of assignment prohibits the assignment of receivables or the transfer of contractual positions without prior consent. It is based on the principle of contractual freedom and can be justified both by law and by contract.
- Protection against unwanted creditor changes
- Preservation of the original contractual relationship
- Control over the quality of contract fulfillment
Prohibition of assignment vs. permission of assignment
While a prohibition of assignment generally prohibits the transfer, an assignment clause permits the assignment under certain conditions. The choice between the two variants depends on the strategic objectives and risk assessments.
Importance in Procurement
In contract management, the prohibition of assignment serves to minimize risk and ensure quality. It prevents critical suppliers from transferring their obligations to less qualified third parties.
Methods and procedures
The implementation of a prohibition of assignment requires strategic planning and legally secure formulation.
Contract design
Precise wording of the clause is crucial for the effectiveness of the assignment prohibition. The provision should cover both the assignment of claims and the assumption of contracts.
- Clear definition of the scope of application
- Determination of exceptions and approval procedures
- Define sanctions for violations
Risk assessment
Before agreeing a non-assignment clause, the specific risks of the business relationship should be analyzed. Critical factors include supplier stability and the importance of the service for the company.
Monitoring and enforcement
Effective contract management monitors compliance with the non-assignment clause and reacts quickly to any breaches. Regular reviews of supplier ownership structures are essential.

Important KPIs for assignment prohibitions
The effectiveness of assignment prohibitions can be measured and optimized using specific key figures.
Compliance rate
The proportion of contracts with properly implemented and complied assignment prohibitions shows the effectiveness of contract management. A high compliance rate significantly reduces legal risks.
- Percentage of contracts with valid assignment prohibitions
- Number of violations detected and prevented
- Average response time for violations
Supplier stability
The continuity of contractual relationships through assignment bans can be measured by the number of unwanted partner changes. Low values indicate successful risk minimization.
Cost efficiency
The costs of monitoring and enforcing assignment prohibitions should be proportionate to the protected contract volume. Automated systems can significantly improve this ratio.
Risks, dependencies and countermeasures
Assignment bans harbor both opportunities and risks that must be carefully weighed up.
Legal risks
Unclear or ineffective assignment prohibitions can lead to legal disputes. Precise wording and regular review of the clauses is therefore essential.
- Ineffectiveness if prohibitions are too far-reaching
- Conflicts with statutory assignment rights
- Enforcement problems with international contracts
Operational dependencies
Strict assignment prohibitions can limit the flexibility of suppliers and lead to higher costs. Particularly in the event of financing bottlenecks, suppliers can be restricted in their ability to act by assignment prohibitions.
Countermeasures
Balanced contract negotiations take into account the interests of both parties. Approval reservations and exceptions can mitigate the disadvantages of strict assignment prohibitions without jeopardizing the protective character.

Practical example
A car manufacturer agrees a mutual non-assignment clause with its strategic IT service provider for all contracts relating to critical systems. When the service provider is to be taken over by a competitor, the non-assignment clause takes effect and prevents the automatic transfer of the service contracts. The manufacturer can now check the qualifications of the new owner and develop alternative solutions if necessary.
- Early identification of potential risks
- Maintaining the negotiating position
- Protection against loss of quality due to unsuitable successors
Current developments and effects
Digitalization and changing market structures have a significant impact on the application of assignment prohibitions.
Digital transformation
Modern digital contract management systems enable automated monitoring of assignment prohibitions. AI-based tools can detect potential violations at an early stage and optimize compliance processes.
Supply chain complexity
Increasingly complex supply chains require differentiated assignment regulations. Companies must differentiate between strategic partnerships and standardized supply relationships.
- Flexible approval procedures for different supplier categories
- Automated notifications of ownership changes
- Integration into supplier relationship management systems
Regulatory developments
New laws on supply chain transparency increase the importance of assignment prohibitions. Companies must ensure that regulatory requirements are met even after assignments.
Conclusion
Assignment prohibitions are an important instrument for minimizing risk in contract management and protect against unwanted changes to the contractual partnership. Successful implementation requires a balanced consideration of protection interests and operational flexibility. Modern digital tools support the efficient monitoring and enforcement of these contractual clauses. Companies should use assignment prohibitions strategically and regularly adapt them to changing market conditions.
FAQ
What is the difference between prohibition of assignment and exclusion of assignment?
A prohibition of assignment generally prohibits the transfer, while an exclusion of assignment excludes certain types of assignment. The prohibition is more comprehensive and offers greater protection against unwanted changes to the contract.
Can a prohibition of assignment be agreed retrospectively?
Yes, assignment prohibitions can also be introduced retrospectively by amending the contract. However, this requires the consent of both contracting parties and should be legally checked to ensure effectiveness.
Which exceptions to the prohibition of assignment make sense?
Typical exceptions relate to assignments to affiliated companies, factoring companies or in the case of corporate restructuring. The exceptions should be clearly defined and limited to legitimate business purposes.
How is a breach of the prohibition of assignment sanctioned?
Violations can lead to the invalidity of the assignment, claims for damages or even termination of the contract. The specific sanctions should be clearly regulated in the contract.
