Consent of landlord
2. If the lands sought to be partitioned are held subject to any agreement or condition restraining or prohibiting assignment or subdivision, or if they form part of an estate upon which the assignment or subdivision of holdings without the consent of the landlord is contrary to or not warranted by the practice prevalent upon such estate, the plaintiff shall at the hearing produce the consent in writing of the landlord, or his agent duly authorised for that purpose, that the lands in the civil bill mentioned be partitioned or sold as the court may direct.
