The article is an extension of the speech delivered at the Conference “Ethical Problems in Psychotherapy” which took place in Krakow on the 9th of February 2019 and was organized by Professor Maria Orwid Foundation for the Development of Psychotherapy in Krakow. The aim of the article is to accentuate some ethical aspects that appear during the first consultations and during the process of therapy for couples and marriages. The issues considered are: the availability of therapy for couples experiencing a crisis in their relationship, the duration and direction of therapy and the selection of therapeutic techniques. Determination of the desired treatment effect is assessed. The aspect of power and responsibility in couple therapy, the importance of the therapist’s gender in the therapy process, the possibility of the therapist refusing therapy and the problem of trust are discussed. The above-mentioned issues are presented in the light of the following phenomena: neutrality, balance and justice in the dyadic relationship.
