Fundamentally, the trade registry is the official registry, which serves the public to have information and to prove, peculiarly for third parties, by providing publicity about its existences with the registration of the things regarding the commercial enterprise. The constitutor or explanatory in terms of whether the matter subject to registration is legally occur or not; it may show positive or negative effects in terms of whether third parties are deemed to be bona fide or not. As well, if there is a difference between the registration and the declared situation within the framework of the principle of trust in opinion, the third parties' trust in the advertised situation is protected unless it is proven that they know the real situation that has been registered. Apart from these, the third parties in the trade registry are characterized both in designating the criteria to be applied in the examination of the subject to registration and in the situations that arise as a result of the application of third parties to the trade registry commerce under specific conditions. Within this context, we testify that the direct or indirect effects of trade registry on third parties are the subject of widely research in the doctrine. Though, no legal regulation has been made regarding the identity of the third person who is/will be the addressee of the effects of the trade registry. Therefore, the legal gap in this matter should be filled by setting several criteria for the determination of the third party in the trade registry records. Therefore, the legal concept of 'third party' in the trade registry records will be examined specific to the tax office.
