The right to participate of the child is guaranteed in the Convention on the Rights of the Child and the European Convention on the Exercise of the Rights of the Child. The child, as a party or a third party, should be informed about the proceedings in which his/her legal status is affected, be given the opportunity to express his/her express his/her views and opinions, and be informed about the possible consequences of the decision to be rendered. The right to be heard in proceedings concerning the child is manifested in the form of the child’s right to participate. In order to exercise the right to participate, the child must have the ability to form his/her own opinions. The ability to form his/her own opinions is a broader concept than the discernment. The child who has this ability can exercise his/her right to participate personally or through his/her legal representative. The fact that the child with limited capacity, who has the power of discernment, does not have the capacity to sue cannot be interpreted as that the child cannot exercise the right to participate in person. It is a requirement of both the right to be heard and the right to participate that the child who follows the proceedings through his/her legal representative expresses his/her opinion about the proceedings and is heard within this framework. The child who does not have the ability to express his/her views may exercise his/her right to participate through his/her legal representative. It is possible for the child to be heard and to exercise the right to participate in both contentious and non-contentious proceedings. In this context, the characteristics of both types of jurisdictions are taken into account. In proceedings where the principle of ex officio action and ex officio investigation prevails, the child should also be allowed to express his/her opinion.
