Due to their vulnerability, sensitivity and position in society, children are provided with special support and protection. Therefore the Family Code has brought a number of novelties in the field of family law, which aim to improve the situation of the child, effectively ensure the implementation of the principle of the best interest of the child and prevent specific danger to children in the home environment. Parents are primarily responsible for the upbringing, care and wellbeing of the child, within the framework of an insitute of Parental care. The state can and must intervene in the family relationship, when the child grows up in a family environment that is not suitable for his development and thus his best interests are endangered. When this occurs, the Family Code has given the courts and social services a general authority to take actions and impose the child. A novelty brought by the Family Code is a unified system of measures and procedures on measures for the protection of the best interest of a child. The measures are decided by a court in non-contentious proceedings which implement the principle of best interests of a child more effectively. This master thesis presents measures for the protection of best interests of a child among which the Family Code includes interlocutory injunctions, urgent child abduction and a set of long-term measures to protect the best interests of the child: restriction of parental care, decision about medical examination or treatment, restriction or removal of the right to contact, removal of a child, placement of a child in an institution and removal of parental care. The intensity of measures is determined according to the level of risk to the child. The greater the risk to the child, the more restrictive the measures will be.
