While better known for containing principles about the right to partition, section 1030 of the Civil Code of Québec nonetheless contemplates situations in which the right to partition becomes “impossible because the property has been appropriated to a lasting purpose”. Appropriation for a lasting purpose is generally confined to objective appropriations of property for the use or exploitation of another property. Yet, section 1030 CCQ is drafted in such a general way that it makes it possible to speculate as to wonder about the possibility of whether appropriations actually need to be in direct relationship with another property. Drawing on case law and doctrinal analysis, this paper reveals the existence of subjective appropriations. Subjective appropriations would allow for the severance, without dependency relationship between appropriated undivided property and other property. Appropriation for a lasting purpose would then rely on a crystallized collective/shared interest representing the sum of ownership interests, or even an autonomous collective interest. This would bring a new light on indivision (or undivided co-ownership): a modern device allowing collective, thoughtful and sustainable management of undivided property/community property.
