What is the position where a tenant has brought part of his/her croft so that he/she is part owner, part tenant. If he sells the whole of the owned part, is that now a division requiring Commission consent?

In the Commission’s view division is not required because a person who has part of the croft is not an owner-occupier crofter. Accordingly there is no requirement to divide, and indeed any such division application would be incompetent. A person who wishes to sell the part croft which he/she owns is free to do so but on the understanding that the croft entity remains whole, and he is not dividing the croft by selling it.
