There is no fixed number. A “safe” termination depends far less on how many warnings were sent than on the gravity of the breach, the reasonableness of the period allowed and the chain of documents behind it. For continuing obligations the Turkish Code of Obligations (No. 6098) works from termination for just cause and, for material breaches, from a warning with a reasonable period. In practice the courts look for a staged process in which the breach was notified in writing, a realistic period was given to put it right, and any repetition was recorded.
A single serious breach can justify termination without any warning at all, while an accumulation of minor breaches needs a consistent history of warnings behind it. And because a goodwill indemnity argument can arise in long-standing distribution relationships, the grounds and the timing of the termination should be constructed with that risk in view as well. What decides it is not the count but a process that is consistent and documented.
