The Act of 17th September 2021 amending the Act on remuneration of persons holding senior posts in state administration and some other acts deals with social and health insurance of the spouse of the President of the Republic of Poland. This regulation is exceptional due to the method in which it was adopted and due to a very narrow scope of its application. It is also worth considering because of new solutions, different from those applied previously. Such solutions as admissibility of indicating the person covered by social insurance, a peculiar definition of accident at work or sickness insurance coverage for persons whose activity does not affect this person's or family's income are analysed in this paper. Methods of providing social security to the spouses of the Presidents of the Republic of Poland that could be considered as alternative to social insurance are also discussed.
