A post graduate in Business Law is generally not a suitable enough qualification for an in house counsel in any situation as it does not cover the wide gamut of the law, an undergraduate in laws would normally have acquired in his/ her studies.
Business laws from one country to another vary in practical application and in theory. I would have serious doubts about the credibility of any company whether foreign or local who would engage a person without the rigour and depth of knowledge of at least an undergraduate regardless of thir status within the profession. i.e. whether certified to practice or admitted.
General or in house counsel require to be possessed of procedure, knowledge of contracts, the civil and criminal law, corporations law, the constitution, administrative law, property law, taxation, succession, local government laws, planning laws, and numerous other areas of the legal system in order to provide the company with sound advice on any and every action they encounter or propose to take.
it is a position that requires skill and knowledge. Profound knowledge. However if the company that proposes to engage you in this capacity are prepared to risk it and the Malaysian authorities are prepared to let you in on that basis. Good luck to you both.
