A lot that is adjacent to another and is separated by a lot line (property line). Article 1100 of the Civil Code of Quebec allows co-owners of contiguous private portions to alter the boundaries of their private portions, without it being necessary to obtain the majority provided for in article 1097 of the Civil Code of Quebec, provided they obtain the consent of their hypothecary creditors and of the syndicate. No alteration may increase or decrease the relative value of the group of private portions altered or the total of the voting rights attached to them.
By purchasing a condo (apartment) in a residential tower, you automatically become an owner in a vertical co-ownership. You can also be in a divided co-ownership, if you purchase a house (semi-detached or townhouse), built on the same lot than other individual homes. It is then called a horizontal co-ownership.
If this is the case, you may not be the sole owner of the land surrounding your home. You will therefore share with others the ownership of the private streets leading to the homes and common areas, and the common equipment such as the swimming pool and collective parking.
