In the Turkish Inheritance Law, general principle of heritage’s sharing, except the statue of wife’s heiress, is class heirs’ and heiress’ equality in terms of heritage part. In this respect, inheritors have equal parts of heritage if there isn’t any arrengement in law or transaction of legator contrary to this rule. But this equality may deteriorate with legator’s transaction or her/his testament. Legislator had given an opportunity to heirs and heiresses who suffer from this transaction in order to provide this equality. This facility is regulated in the Turkish Civil Code art. 669 ff under the title “equalization in heritage”. In fact, inheritance law is interested in person’s property status after his/her death or people’s status who have rights on this heritage. So equalization in heritage is an exceptional rule which can interfere to the transactions made between alive people. In this study these provisions are examined.
