Reporting family composition is not an employment obligation, unless there are company policies on family ties. But if you want your partner, daughters, sons and daughters to enjoy the social welfare benefits offered by your company, as well as maternity, paternity or bereavement leave, and for your family to have the status of beneficiaries in health and in the family compensation fund, your employer will need to know the information of your spouse, permanent partner, your sons and daughters, as well as your dependants, for example, your partner's sons or daughters who live with you.
