Commonwealth realm
In each of the countries outside the UK, the King appoints a Governor-General to represent him, who, after consulting with the government of the realm, has all of the powers and duties of the Monarch. Usually the Governor-General signs all acts of parliament into law, but can wait and ask the King for advice or wait for him to sign the act himself.  This happened in 1982 when Queen Elizabeth signed the important Canadian Charter of Rights and Freedoms during a visit to Ottawa, and the Australia Act 1986 in Canberra.
