First of all, it should be noted that guardianship is established only for minors (who have not reached the age of 14), who have been deprived of parental care or have become orphans, as well as for incapacitated persons.
In the event that it is necessary to establish guardianship over a disabled person of the 1st group, then such a person is first recognized as incompetent in a court of law, and then a guardian is appointed to him.
It is necessary to apply for the appropriate application for the establishment of guardianship at the place of registration of the person who needs guardianship, or at the place of actual residence of the future guardian.
