Co-ownership of land works well until the co-owners fall out. When one wants to sell and another refuses, when the property sits idle while its costs mount, or when death or incapacity leaves a share stranded in the hands of someone who cannot or will not act, Singapore law provides an exit. A co-owner may ask the court to order a sale of the land in lieu of partition, and to distribute the proceeds. The power is discretionary and turns on whether a sale is "necessary or expedient", but it is real, and an uncooperative co-owner cannot block it. This article explains the statutory basis, the test the courts apply, and how the mechanism copes with two common complications: a co-owner who has died leaving an unadministered estate, and a co-owner who lacks mental capacity.
To make the doctrine concrete, consider a recurring pattern. A residential property is held by three co-owners in equal shares. One co-owner has died some years ago without any grant of probate or letters of administration having been taken out, because a beneficiary of that estate refuses to cooperate. A second co-owner has since lost mental capacity, for instance through dementia, and can no longer manage his own affairs. The third co-owner wishes to sell, cannot obtain the others' cooperation, and is left carrying the property's costs while a family dispute festers. Each strand of that hypothetical raises a distinct legal question, and Singapore law has an answer to each.
The Statutory Power to Order a Sale Instead of Partition
The court's power is conferred by statute. Section 18(2) of the Supreme Court of Judicature Act 1969 (2020 Rev Ed), read with paragraph 2 of the First Schedule, gives the General Division of the High Court:
"Power to partition land and to direct a sale instead of partition in any action for partition of land; and in any cause or matter relating to land, where it appears necessary or expedient, to order the land or any part of it to be sold, and to give all necessary and consequential directions."
This is a substantive power, not a mere procedural convenience. As the High Court explained in Sin Chiau Soon v Aitken Robert Bond [2025] SGHC 94, the provision contains two distinct limbs. Under the first, the court may direct a sale instead of partition "in any action for partition of land"; a co-owner may apply directly under this limb without needing a separate cause of action against the others. Under the second, the court may order a sale "in any cause or matter relating to land" where that is "necessary or expedient", typically for the purposes of pending proceedings. The power descends from the English Partition Acts 1868 and 1876, which first allowed courts to order sale in place of physical division, and whose exercise never depended on a separate underlying claim, a lineage traced in Sin Chiau Soon through Abu Bakar v Jawahir [1993] 1 SLR(R) 865.
The practical consequence is that a co-owner who wants out can commence an Originating Summons in the General Division of the High Court seeking an order for sale in lieu of partition, relying on the first limb, without having to construct some other legal grievance first.
