In the past few years, the number of marriages ending in divorce has been an increasing trend. Consequently, single-parent families are becoming quite a usual sight nowadays. Dissolution of marriage often represents a painful and complex experience and stands for one of the highly stressful events for the entire family. Besides parents, children are heavily affected by the newly introduced changes as well. They are exposed to unpleasant parental conflicts and are likely to be used as a tool in manipulative behaviour exerted by either the mother, or the father, in order to „win“ an argument. Such inadequate and devious parental actions often lead to alienation of a child away from one of the parents. The goal of this Master’s thesis is thorough analysis of the official documentation belonging to the Center for Social Welfare which describes divorce with known or possible implications of child alienation. Outcomes of the analysis will serve to deduct whether it is possible to predict child alienation based on certain behavioural traits. In addition, the thesis will look into the potential legal measures, available under the juridical system of the Republic of Croatia, which institutions in charge can take in order to adequately protect a child's best interests. This research showed it is indeed plausible to predict child alienation from particular parental behaviour, however, discussing such topics is strongly stigmatised in the current society. Results have also shown there is an urgent need for a better legal definition of child alienation issue so that authoritative institutions could effectively act to protect child’s rights.
