According to the German Civil Code (§ 1601 BGB), parents are generally obliged to support their children of full age up to a professionally qualifying degree. Therefore a study is included.
However, the amount of maintenance depends on the financial ability of the parents. They are granted an appropriate amount for their own subsistence level. Child benefit and tax allowances help parents to pay support to their children.
Students who do not live with their parents can generally require 860 euros per month as maintenance from their parents. The costs for the students' health and nursing insurance and any tuition fees are not yet included.
However, income (e.g. from jobbing), an inheritance or money saved by students reduce the parents' obligation to support their studying children.
As a rule, parents are only obliged to pay maintenance up to the first degree qualifiying them for their profession. The students are free in the choice of their subject and can change their place of study and field of study to a limited extent without the right to maintenance from their parents disappear.
In return, students are obliged to provide their parents with information and proof of the progress of their studies. Students must study quickly and goal-oriented in order to keep the maintenance burdens of their parents as low and calculable as possible. If this obligation is violated, the claim to maintenance from the parents can be reduced or even cease.
