Yes, family members can help in your business, but they need to be officially registered if they're working in the family business. This means you must submit their engagement form to Jobsplus. According to Article 39 of the Employment and Training Services Act (Chapter 594), “For the purposes of this Act, a person performing work in any place of work shall be deemed to be employed or self-employed.” Voluntary workers can only offer their services to registered voluntary organisations or charitable institutions.
