In principle, all costs for the upbringing and care of your children fall under child support. A distinction is made between accommodation costs, accommodation-exceeding costs and extraordinary costs. Accommodation costs are the costs you have when your children are with you. Think of: Food and drink Body care Housing Trips and holidays Toys Overstay costs include: Clothes and shoes The hairdresser Sports dues and supplies Costs for music lessons and instruments Subscriptions A bicycle or costs for public transport Unreimbursed medical expenses Extraordinary costs are costs that occur once or occasionally. Think of costs for glasses, braces, driving lessons or a study. In principle, all of the above falls under child support. You are responsible for including these costs in the calculation of alimony. If you do not include the costs of glasses, for example, but your child needs them later, the caring parent must, in principle, pay these costs.
