The article is devoted to the problem of the support for the family by public authorities in the light of the provisions of the Constitution of the Republic of Poland. The article discusses the essence of the family, the good of the family as a constitutional value, the right of a family in a difficult material and social situation to special help from public authorities and the issue of help given to the mother before and after childbirth (Article 71 of the Constitution). According to the author, the Constitution creates sufficient grounds for providing support by public authorities to families which require such support. In this respect, the key issue is the requirement to take into account the good of the family in the state’s social and economic policy. However, the final shape and scope of assistance is determined by law.
