    Dispute resolution and settlement procedures are becoming increasingly important in this time of global financial crisis, particularly in the commercial field. Consequent to the need for specialized legal counsel to prevent further disputes by structuring investments and partnerships appropriately, post-transactional litigation advice and insight into Turkish procedural law applicable to dispute resolution have become more relevant to foreign investors in Turkey.
