Family benefits are aimed at providing financial support to families with dependent children. The Polish legislator is aware that the birth of a child into a family is a great revolution for the parents, who will have to face the challenge of upbringing and providing the child with decent living conditions. The author of the article has drawn attention to the state’s constitutional duty of helping families and to the elaboration of that duty in the Family Benefits Act. In particular, she has analysed one-time childbirth allowance, childbirth supplement to the family benefit, and one-time municipality childbirth allowance. All these benefits have a one-time character, being paid only once and for one child only. By granting financial help to families on the occasion of childbirth, the legislator shows concern for the family that is in a new situation, but this is only one-time support.
