The two McAlpine firms had non-compete arrangements and sites had a common “McAlpine” board irrespective of which firm it was. When both companies first went public, they did so under the names Newarthill for Robert and Marchwiel for Alfred. These arrangements continued until 1983. In 2003, Sir Robert McAlpine Ltd sued Alfred McAlpine plc over the use of the family name and won. The dispute centred on Alfred McAlpine's intention to trade under the name "McAlpine". There was previously a long-standing agreement within the McAlpine family not to make such a change but, following the death of Alfred McAlpine and his son, the board of Alfred McAlpine sought to make the change in any event. The effect of the judgment was to prevent Alfred McAlpine trading under the name "McAlpine". In 2008, Alfred McAlpine plc was acquired by Carillion and dismantled, thus making the "name war" irrelevant.
