hi,
1.yes there exist implied warranties in the Turkish law which are regulated by either the code of obligations and the Act of Consumer Protection .These warranties are implemented in a complemantary fashion that the consumer may avail himself of both yet the specific law confers more favourable terms. Those include, the repair,replacement,refund and the reduction of the amount of money providing that the defect of the relevant good is reported in the due period(apart from the misleading of the consumer in which case time limitation is not applicable)

2.Sorry could not locate the question but if 'transfer of claim' is in question, this legal model is laid out by again the C.of Obligations, the articles 162 and others.The very Article stipulates that the creditor may transfer the claim irrespective of the consent of the debtor, not including the cases in which the contary is laid down via law or the circumstances compel so.
3.Since the labour law in Turkey inherently favours the worker , thus the disadvantageous terms of labour contract for the worker that provides worse conditions of work as opposed the labour Act is a violation of the Labour law.The limitation of liability therefore apllies for the side of the worker but not the employer.
4.Because the C.of Obligations and the Civil Code is inspired or recepted from the Swiss law, it is no doubt that similarities exist between the two systems.Yet, the Civil Code was subjected to a wide amendment recently, the former one remains unchanged excepting several changes occured.
