Aim. The aim of this article is to illustrate the functioning of a family having a person with a disability, highlighting its key role in the processes of care, support, and social integration. A definition of the family as the first, fundamental, and most important environment in a person’s life is provided. The concept of disability is explained with reference to the United Nations Convention on the Rights of Persons with Disabilities. The article also seeks to analyse the challenges and needs of families with a person with a disability and to identify the forms of support offered to them by institutions, including associations. Methods and materials. The article is based on a subject literature review, which was complemented by insights gained from many years of professional experience in the field. Comparative analysis was applied to selected international examples of support systems for families raising children with disabilities. These examples include practices implemented in France, Great Britain, Sweden, and Australia, offering a broad perspective on diverse systemic solutions.Results. The analysis reveals that families of people with disabilities face significant burdens, both emotional and financial. While systemic forms of assistance exist, they often fail to correspond to the real needs of families. International examples demonstrate that, despite different organisational frameworks, the common objective is to ensure family stability, foster integration, and promote the active participation of people with disabilities in social life. Particular emphasis is placed on the role of the Polish Association for Persons with Intellectual Disability (PSONI) – the oldest non-governmental organisation in Poland serving this community. Its activities highlight the importance of non-institutional, grassroots initiatives in complementing state support systems. Conclusion. Effective institutional support can significantly enhance the quality of life for both people with disabilities and their families. However, in practice, access to such support is often limited or inadequate. Families frequently report insufficient knowledge of their rights, available services, and strategies for managing everyday challenges. Education and counselling are therefore key elements of effective assistance. The article concludes with recommendations for strengthening support systems through interdisciplinary approaches and intersectoral cooperation. This would allow for more responsive and tailored solutions, ensuring that families receive the resources they need to thrive and to facilitate the full social integration of people with disabilities.
