Mothers and fathers residing permanently in Germany can obtain child benefit. It is generally paid until a child reaches the age of 18 and even longer in certain cases. You make the application to the Family Benefits Department at the Federal Employment Agency.
Single parents and low-income parents can make an application for supplementary child benefit. The level of supplementary child benefit is based on the income and assets of the parents and children, it amounts to a maximum of Euro 185/ child and is paid monthly together with the child benefit. The Family Benefits Department will provide you with information about the conditions for applying.
