Monetary claims can be transferred in an asset deal even when the underlying contract contains an assignment ban. Section 1396a of the Austrian General Civil Code provides that, for certain monetary claims between businesses, even a binding assignment ban does not prevent the assignment from being effective. Buyers and sellers therefore need a precise contract review, a clear notice to the debtor and a clean distinction from a transfer of the entire business.

This article addresses the transfer of individual business-related monetary claims. It explains when an assignment ban is binding, how notice to the debtor affects payment and how the transfer should be integrated into the acquisition agreement and closing process.

The issue is distinct from the assumption of an entire supply or other contract. Section 38 of the Austrian Commercial Code contains separate rules for business-related legal relationships. The overview of share acquisitions and transaction structures gives further context.

01 Question 1

Does the underlying contract contain an assignment ban for the monetary claim?

Check whether the claim arose between businesses from a business transaction and how the ban was agreed.

All paths at a glance

Overview of all answers.

01

The claim can be assessed safely only after the original contract is clarified.

Request the complete claim contract, amendments, side agreements and documents showing how the claim arose. Record whether the parties are businesses, which transaction is involved and whether the assignment ban was individually negotiated.

Until these points are clear, treat the claim transfer as an open closing item. The due diligence topic page provides the wider transaction context.

02

The transfer is prepared when contract, notice and payment route fit together.

Identify the claim clearly in a schedule to the acquisition agreement. State when the debtor will be informed of the assignment and assignee, where payments must be made and which post-closing cooperation the seller owes.

The statutory effect of the assignment ban and the commercial allocation of risk are separate questions. Record any debtor rights against the transferor and the agreed treatment in the acquisition agreement.

03

The claim transfer needs a reliable completion rule before closing.

Align the assignment, debtor notice and treatment of incoming payments in one closing schedule. The agreement should also state who handles debtor questions, disputes and payments made to the former creditor.

Review this transfer together with the rest of the asset deal. Section 38 of the Austrian Commercial Code contains separate rules for business-related legal relationships when a whole business is continued. Those rules do not replace the review of an individual monetary claim.

Identify the monetary claim and assignment ban

Section 1396a of the Austrian General Civil Code concerns an agreement that a monetary claim between businesses arising from business transactions may not be assigned. Before drafting the transfer, the parties must identify the claim, its contractual basis, the creditor and the debtor. A general data room entry does not establish that allocation.

The buyer should record the claim with contract number, debtor, invoices, balance and due date. The complete underlying contract also belongs in the data room. For continuing services, check whether the claim has already arisen, will arise later or may be affected by debtor objections.

When an assignment ban is binding

Under section 1396a(1), an assignment ban is binding only if it was individually negotiated and does not grossly disadvantage the creditor after all circumstances of the case are considered. The two requirements relate to the specific agreement. Calling a clause an assignment ban does not by itself establish its binding effect.

The transaction file should therefore contain the draft contract, negotiation correspondence and relevant versions. They may show how the clause was agreed and what its economic significance was for the creditor. Also check the statutory exception in section 1396a(3). Paragraphs 1 and 2 do not apply to assignment bans agreed between a public-law legal entity, or an institution founded by one, and a grant applicant.

How the assignment operates despite the ban

Even a binding assignment ban does not prevent the assignment from being effective under section 1396a(1). This rule concerns the assignment of the monetary claim. It explains why a buyer can transfer an individual claim in an asset deal although the original contract prohibits assignment.

Once the assignment and the assignee have been made known to the debtor, the debtor generally can no longer discharge the debt by paying the former creditor. Section 1396a(1) contains an exception where only slight negligence can be attributed to the debtor. Notice therefore belongs in the closing plan and should identify the claim, the assignee and the payment route clearly.

Separate debtor rights from the parties’ liability

Section 1396a(2) leaves the debtor’s rights against the transferor for breach of a binding assignment ban unaffected. Those rights cannot, however, be raised against the claim. The buyer should therefore check whether disputes arise from the original contract or from the prior administration of the claim.

The assignee is not liable to the debtor solely because it knew of the assignment ban. This is not a general release from every claim risk. The parties still need to establish whether the claim exists, whether counterrights or objections exist and who will pursue or defend the claim after closing.

Distinguish an assignment from transfer of business

Section 38(1) of the Austrian Commercial Code governs a transfer of business. A person who continues a business acquired inter vivos generally assumes the transferor’s business-related, non-personal legal relationships, including rights and liabilities already established, unless otherwise agreed. The acquisition of an entire business therefore has a different statutory basis from the transfer of one monetary claim.

Under section 38(2), the third party may object to the assumption of its contractual relationship within three months after receiving notice. The notice must mention the right to object. This rule for a contractual relationship must be separated from the notice of an assignment under section 1396a. The acquisition agreement should state which claims are assigned individually and which relationships are intended to pass with the continued business.

Review grid

Assignment ban and transfer of business compared

The two statutory rules lead to different review and completion steps.

Individual monetary claim and transfer of business
Review field Individual monetary claim Transfer of business
Legal basis Section 1396a Austrian General Civil Code Assignment may be effective despite a binding ban Section 38 Austrian Commercial Code: business-related legal relationships on continued operation
Core documents Underlying contract and claim schedule Clause, balance and claim basis Acquisition agreement and contract inventory: assumed legal relationships and liabilities
Notice to third party Disclose assignment and assignee Clarify the post-transfer payment route Disclose assumption, mention the objection right and observe the three-month period
Contract consequence Debtor rights against transferor remain Allocate enforcement and cooperation Consider continuing transferor liability under section 39 and any agreement with third parties

The grid does not replace a review of the contract. Claim, underlying transaction, business structure and notices must fit together.

Important: The assignment ban and the effectiveness of the assignment are separate questions under section 1396a. Before closing, secure the original contract, claim schedule, debtor notice and payment instructions.

Secure the claim transfer in the acquisition agreement

The acquisition agreement should identify each affected claim or a clearly determinable category of claims. It can also state whether the assignment is completed at signing, closing or a defined documentation step. The claim schedule, assignment document and debtor notice belong in one closing script.

The commercial allocation is equally important. The agreement should state who monitors receipts after the cut-off date, who provides information and who cooperates in a debtor dispute. A clear allocation prevents the buyer from holding the claim while remaining dependent on the seller for essential records.

The article on regulatory approvals in a business acquisition covers further asset deal issues. The topic page on the acquisition agreement places individual clauses in the wider transaction structure.

FAQ

Common questions on assignment bans and claims

Is an assignment effective despite an assignment ban? +

Under section 1396a(1) of the Austrian General Civil Code, even a binding assignment ban does not prevent an assignment of an affected monetary claim from being effective. The statutory requirements and the actual contract still need review.

When must the debtor be notified? +

Section 1396a(1) links the change in the debtor’s discharging payment effect to notice of the assignment and assignee. Notice should therefore be prepared and documented as a separate closing step.

Does section 1396a also govern the acquisition of an entire business? +

An individual assignment of a monetary claim is distinct from the acquisition of an entire business. Section 38 of the Austrian Commercial Code contains separate rules for business-related, non-personal legal relationships on continued operation.

Is the buyer liable solely because it knew of the ban? +

Under section 1396a(2), the assignee is not liable to the debtor solely because it knew of the assignment ban. Claim existence, objections, enforcement and cooperation should still be allocated in the acquisition agreement.
