Co-owned land is divided by a partition action under the Partition Law No. 21 of 1977. Any co-owner may bring one. The court rules on the pedigree of title, declares the shares by interlocutory decree, and enters a final decree that binds everyone.
Land passing to several children, and then to their children, is how most Sri Lankan land ends up owned in undivided shares. Nobody owns a defined portion. Everybody owns a fraction of the whole. A partition action is the mechanism for turning those fractions into separate, saleable, mortgageable blocks.
The governing statute is the Partition Law No. 21 of 1977. It is a Law rather than an Act because it was passed by the National State Assembly, and a citation to a "Partition Act No. 21 of 1977" is citing something that does not exist. It has been amended five times, by Act No. 5 of 1981, Act No. 6 of 1987, Act No. 32 of 1987, Act No. 17 of 1997 and, most substantially, Act No. 27 of 2024.
Who can bring the action
Section 2 is short and wide. Where any land belongs in common to two or more owners, any one or more of them may institute an action for the partition or sale of the land, whether or not their ownership is subject to a life interest in another person.
A single co-owner holding a small fraction can therefore force the process on everyone else. There is no minimum share and no requirement of agreement among the co-owners.
The plaint, and the pedigree
Section 4 requires the plaint to contain, in addition to what the Civil Procedure Code demands:
- the name, extent and value of the land
- a description by physical metes and bounds, or by reference to a sketch, map or plan appended to the plaint
- the names and addresses of everyone entitled or claiming to be entitled to any right, share or interest in the land, or to improvements on it, with the nature and extent of each, so far as known to the plaintiff or ascertainable by him
- a statement of the devolution of title, by reference to a pedigree appended to the plaint
The pedigree is where partition actions are won and lost. It is a family tree of title, and the court is being asked to adjudicate on it. Gaps, guesses and omitted branches produce contested trials, and they produce decrees that bind people who never appeared.
Registering the action as a lis pendens
Section 6 requires the plaintiff to file, with the plaint, an application to register the action as a lis pendens addressed to the Registrar of Lands. Where the land sits in more than one registration district, a separate application goes to each. The applications are filed in triplicate, marked original, duplicate and triplicate.
Section 66 supplies the consequence. Once the action is registered as a lis pendens, no voluntary alienation, lease or hypothecation of any undivided share or interest in the land may be made until the action is finally determined, whether by dismissal, by entry of a decree of partition under section 36, or by entry of a certificate of sale. Anything done in contravention is void, though it is treated as valid if the action is ultimately dismissed.
That freeze is why registration is filed with the plaint rather than later. It is also the answer to the client who asks whether they can sell their share while the case runs.
Amending the pleadings, and the 2024 tightening
Section 24A is new, inserted by Act No. 27 of 2024, and it changes how forgiving the process is about late corrections.
Before the day first fixed for trial, the court has full power to amend all pleadings in its discretion, by addition, alteration or omission, on notice to the parties. On or after that date, no amendment is allowed unless the court is satisfied, for reasons to be recorded, that grave and irremediable injustice will be caused or that a thorough investigation of title will be impeded if it is refused, and that the party applying has not been guilty of laches.
In a case whose whole subject is a pedigree, that is a real constraint. Title research belongs before the trial date, not after it.
Interlocutory decree
Section 26 governs what happens at the end of the trial. The court pronounces judgment in open court, dated and signed, and then enters an interlocutory decree in accordance with the findings.
The decree may contain one or more orders, provided they are not inconsistent with each other, including an order for partition of the land, for sale of the land whole or in lots, for sale of a share or portion with partition of the remainder, or for a portion representing one party's share to be demarcated and separated from the rest.
The interlocutory decree is the point at which shares are declared. What follows is largely the working out of it on the ground.
Final decree
After the surveyor's scheme of partition is considered on the date fixed under section 35, section 36 allows the court, after summary inquiry, to confirm that scheme with or without modification and enter the final decree.
There is an alternative. Where the Commissioner has reported under section 32 that a lot falls below the minimum extent required by written law on subdivision of land for development purposes, the court may order that lot sold at the surveyor's appraised value, and enter the final decree subject to the alterations that follow.
Why a partition decree is so hard to disturb
Section 48 is the reason partition decrees are treated as they are. The interlocutory decree entered under section 26 and the final decree under section 36 are good and sufficient evidence of title to the shares awarded, and are final and conclusive for all purposes against all persons whomsoever, whatever right or title they have or claim.
The Law then says that this holds notwithstanding any omission or defect of procedure, and defines that phrase to include a failure to serve summons on a party, a failure to substitute the heirs or legal representatives of a party who died during the action, and a failure to appoint a guardian ad litem for a minor or a person of unsound mind. The shares awarded come free of all encumbrances other than those specified in the decree.
There are limits, and they are narrow.
- Section 48(4) allows a party who was not served, or who was a minor or of unsound mind and not duly represented, or who filed a statement of claim and registered an address but failed to appear at trial, to apply for special leave to establish their title notwithstanding the interlocutory decree. The application must be made on or before the date fixed under section 35 for consideration of the scheme of partition, or within thirty days after the return under section 42 is received by court.
- Section 48(5) protects a person who was not a party and whose claim is not derived from the decree, but only where they prove the decree was entered by a court without competent jurisdiction.
- Section 48(3) disapplies section 44 of the Evidence Ordinance to these decrees, while expressly preserving the Court of Appeal's powers of revision and restitutio in integrum.
The practical effect is that a partition decree operates against the world, and a person with a genuine claim who was simply never told about the case has a narrow, time-limited route and little else. That is the reason the section 4 pedigree and the naming of parties deserve the care they do.
Appeals, and what the 2024 amendment changed
The appeal structure was reworked by Act No. 27 of 2024 and now runs in three directions depending on what is being challenged.
- Against an order under section 36, the final decree stage, section 36A allows an application for leave to appeal to the relevant High Court established by Article 154P of the Constitution, in terms of section 754(2) of the Civil Procedure Code. Section 36A is not new. It was inserted by section 18 of Act No. 17 of 1997, which sent the appeal to the Court of Appeal with leave, and section 10 of the 2024 Act replaced it to route the application to the provincial High Court instead.
- Against an order under section 45, confirmation of a sale, section 45A allows an appeal to the Court of Appeal with the leave of that court first had and obtained. Section 45A(2) applies Chapter LVIII of the Civil Procedure Code, on leave to appeal, to applications against orders under both sections 36 and 45.
- Otherwise, section 67 provides that an appeal lies to the Court of Appeal against any judgment, decree or order in a partition action, subject to sections 36A and 45A, with the Civil Procedure Code applying as though it were an ordinary action.
The distinction to hold on to is that a challenge to the final decree now goes to the provincial High Court, while a challenge to the confirmation of a sale goes to the Court of Appeal. Both require leave. Anything written before 2024 will describe this differently.
Practical points
- Do the title research before filing. The pedigree under section 4 is the case, and section 24A now makes late amendment difficult once the trial date is fixed.
- File the lis pendens applications with the plaint, one per registration district, and advise the client that section 66 voids any sale or mortgage of an undivided share from that point.
- Name everyone. Section 48 binds people who were never served, which is precisely why a decree built on an incomplete pedigree is a problem the firm will hear about later.
- Watch the section 48(4) windows if acting for someone left out: the date fixed under section 35, or thirty days after the section 42 return.
- Check the appeal route against the current sections 36A, 45A and 67 rather than against older texts, because the 2024 amendment moved them.
Partition is slow, document-heavy work, and most of the difficulty is not legal argument but the reconstruction of title through a family over several generations. The Law rewards that work by making the outcome final in a way few other decrees are. It punishes the absence of it in the same way.
