Identify the obligation, its due date, the breach and your own performance. Review termination clauses, agreed cure periods, notice methods and any special rules for the contract. Confirm which law applies to the agreement and the relevant events, particularly for older transactions.
Article 234 permits a claim for performance or rescission following notice. The court may grant additional time or refuse rescission for a minor breach or one cured by performance. Under Article 235, an automatic-rescission clause does not waive notice unless the parties expressly agree to dispense with it.
A compensation claim needs evidence of recoverable loss and its connection to the breach. Keep delivery records, replacement costs and payment evidence. Distinguish termination from rescission and from a negotiated exit; each can affect outstanding payments and the return of benefits.
A practical next step
Prepare the signed contract, amendments, a dated breach chronology and a loss calculation before sending a termination notice or stopping performance.
