One of the grounds for exemption from military service in accordance with the Law of Ukraine "On Military Duty and Military Service" is: three or more children under the age of 18 are dependent on a serviceman.
The law specifies that 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 parenting or guardianship of three or more children, as well as providing them with material and physical support, including maintenance, education, medical care, etc.
