The war in Ukraine has led to an increase in the need for social assistance among vulnerable populations, which requires strengthening the capacity of social services to respond to new challenges. The purpose of this study is to examine the legal and technological framework for wartime assistance and to demonstrate the effectiveness of modern methods through theoretical and empirical analysis. Data collection and analysis were conducted in compliance with ethical and legal standards for social research. Currently, Ukrainian policy makes it possible to support models such as the proposed Integrated Social Services approach. However, the findings of the study indicate a potential need for legal/regulatory reforms to further strengthen the capacity to respond to crisis situations. The results confirm that the implemented interventions successfully address the problems of displaced persons, veterans, most-at-risk families, etc. Individual case management and group social and psychological trainings contribute to capacity development, and the model of integrated services allows for quick resolution of acute problems. Comparative evaluations show that the integrated system is superior to individual methods in quickly addressing crisis situations. However, new groups that fall outside the scope of current legislation, such as victims of domestic violence, may require mandatory expansion of eligibility criteria. Laws could also include standards for interagency coordination to address fragmentation. This urgent relevance highlights how robust legal/ethical foundations uphold assistance models in turmoil. It was also concluded that the implementation of legal reforms that would create a unified system of cooperation could mitigate these problems. In particular, legislation could formalise requirements such as data and information sharing between service providers, common case management procedures, common reporting standards and interdisciplinary partnerships. The practical significance of the study lies in the possibility of using the results of the problem analysis to create accessible mechanisms to improve the quality of support for vulnerable demographic groups. Enshrining access to care as an inalienable guarantee creates an ecosystem that is resilient to modern threats
