According to § 1619 Civil Code, a child is, as long as it still lives in your household, committed to help in the household or in your business as much as possible. This also applies to adult children who still live with their parents, and even if their child studies abroad or goes to apprenticeship.
Children are required to not cause any damage. Children from the age of 7 years are liable according to their ability to understand. They are liable for the damage incurred if it can be held responsible due to age and maturity.
