You do not need a Company Secretary for a branch office in Singapore. However, it is highly recommended to appoint one as he/she can help you stay in compliance with statutory regulations.
Branch offices are typically an extension of foreign entities in Singapore. So the law does not make it mandatory for them to appoint a company secretary. However, since the branch offices also have stricter administration requirements, it is always best to appoint a company secretary.
