The present work deals with the problem of informal care for the elderly and compares informal care in the Republic of Croatia and Belgium. The largest proportion of care for older people living in their own homes comes from informal providers: family members, friends and neighbors. The paper starts by defining the terms of age, aging and informal care for the elderly. Furthermore, it shows the situation of care for older people in Croatia, and the legislative framework and reforms that have been made. Then we go on describing the situation of informal care in Belgium and their legal framework. Also we are referring to some aspects of caregivers relationships with elderly which we think are very important in conducting informal care. In the end, the topic is completed by domestic and foreign researches on informal care, and we present some new examples of integrated care. Caring for the elderly is an important topic of social policy and social work because of raising the quality of life of older people, and a special emphasis is on informal care as the greatest burden rests on informal caregivers and family. Therefore, we compare two countries to see the similarities and differences in dealing with the burden of a growing demographic trend of aging population.
