A postponement for important personal reasons under section 6 no 1 StVG is possible only for a sentence of up to three years and for at most one month.
Important personal reasons under section 6 no 1 StVG are, for example, visiting a relative who is critically ill or injured, attending a funeral or settling important family matters. This ground for postponement is narrowly limited: it comes into consideration only if the prison sentence to be served does not exceed three years. The postponement may last at most one month. The period runs from the day on which the sentence would otherwise have had to be started.
What to do now: First, check whether the sentence stays within the limit of three years; otherwise this route is excluded. Second, document the personal reason, for instance by a medical confirmation or proof of the funeral date. Third, file the application in good time before the date for starting the sentence and plan realistically for the narrow period of at most one month.
