Abstract This article provides a comparative analysis of the legal regulation of child support, examining international practices alongside the legislation of the Republic of Azerbaijan. The study explores the "Income Shares," "Percentage of Income," and "Melson" models widely utilized in the United States and other jurisdictions, detailing their operational mechanisms and relative advantages. By comparing the provisions of the Azerbaijani Family Code regarding the determination and collection of alimony with international standards, the research identifies key similarities and structural differences. Furthermore, the paper covers the legal establishment of paternity, the criteria for modifying support orders, and the administrative and criminal sanctions imposed for non-compliance. The findings emphasize the necessity of refining legal enforcement mechanisms to secure the socio-economic well-being of children within diverse family structures.
