I have two children of my own and one of my own, minors.

According to the legislation of Ukraine, in order to be exempted from military service, it is necessary not only to have three or more children, but also to actually support them. Therefore, when submitting an application for dismissal to a serviceman together with a report on dismissal, it will be necessary to present evidence that he actually supports three or more children, since the main criterion is the maintenance of three or more children. "Maintenance of three or more children" should be understood as the fact of parenting or guardianship of three or more children, as well as providing them with material and physical support, including maintenance, education, medical care, etc.
