You may be entitled to increased family allowance if your child has a confirmed disability degree of at least 50 percent that is expected to last more than 3 years. The increased family allowance is paid for as long as you receive the general family allowance. Under certain conditions, the family allowance is granted until the 25th birthday. For children with a disability who are unable to work, no age limit applies.
