Enforcing a builders lien in BC requires filing a Notice of Civil Claim in BC Supreme Court and registering a certificate of pending litigation against the property title, both within one year of the lien’s registration date. A lien that is not enforced within that period is permanently extinguished.
A builders lien gives contractors, subcontractors, workers, and material suppliers a statutory right to claim against real property for unpaid work or materials on a BC construction project, with exemptions to highways or some municipal projects. Filing the lien at the Land Title Office is the first step, not the last. The Builders Lien Act, SBC 1997, c. 45 imposes two non-negotiable deadlines: register the lien within 45 days of substantial completion, abandonment, or termination, then commence an enforcement action in BC Supreme Court within one year of registration. Both deadlines are absolute. This guide sets out the enforcement procedure in full, covering the Notice of Civil Claim, the certificate of pending litigation, the consequences of missing the enforcement window, and what subcontractors and suppliers must do independently to protect their own claims.
What Does Enforcing a Builders Lien in BC Actually Require?
Enforcing a builders lien in BC means commencing a civil proceeding in BC Supreme Court by filing a Notice of Civil Claim, and registering a certificate of pending litigation (CPL) against the property title, with both steps completed within one year of the lien’s registration date at the Land Title Office.
A registered lien places a statutory charge against the owner’s interest in the land and the improvement. That charge encumbers the title, blocks clean sales and refinancing, and signals a live payment dispute to every party dealing with the property. The leverage is real, but it is time-limited. A lien with no court proceeding behind it expires after one year. Enforcement converts a registered charge on title into an active court case with the possibility of a judgment, a forced sale, and payment.
Two instruments drive the enforcement process. The Notice of Civil Claim is the court document that formally commences the legal proceedings. It sets out the parties, the contract terms, the work performed, the amounts unpaid, and the relief sought. The CPL is a separate Land Title Office registration that alerts anyone searching the property title that active litigation affecting the property is underway. Both are required. Filing the Notice of Civil Claim without registering the CPL does not preserve the lien right beyond the one-year deadline.
Step 1: File a Notice of Civil Claim in BC Supreme Court
The Notice of Civil Claim is the court document that commences the builders lien enforcement action under sections 26 and 33 of the Builders Lien Act. It must be filed in BC Supreme Court within one year of the lien’s registration date. Filing after that date extinguishes the lien right permanently.
The Notice of Civil Claim must identify all lien claimants and named defendants, describe the construction project and the scope of work performed, state the amount of the claim with particularity, and specify the relief sought. Standard relief in a builders lien action includes a declaration that the lien is valid and subsisting, an order that the property be sold if the judgment is not satisfied, and a personal judgment against the defendant for the unpaid amount. The document is governed by the BC Supreme Court Civil Rules. A claim that omits required particulars can be struck, and a defective claim struck after the one-year window closes cannot be replaced.
Naming the correct defendants is not optional. The defendants in a standard enforcement action include the registered owner of the property, the head contractor if the claimant is a subcontractor, and all other parties with registered interests in the property who could be affected by the lien judgment to claim priority. A party with a registered interest who is not named in the proceedings may take free of the lien. Land title searches are not optional at this stage: the claimant must know what charges and interests are registered against the property before filing.
The procedural requirements under the Builders Lien Act, SBC 1997, c. 45 interact with the BC Supreme Court Civil Rules in ways that produce errors in self-prepared claims. Common mistakes include naming the wrong owner, omitting a required defendant, or misstating the amount of the holdback. Errors that exist after the lien limitation period are permanent: the court has no discretion to permit amendments that revive an extinguished lien right. Most claimants retain legal counsel to prepare the Notice of Civil Claim before the deadline. Contractors pursuing claims may also benefit from understanding broader construction disputes in BC and how lien enforcement interacts with breach of contract litigation.
Step 2: Register a Certificate of Pending Litigation Against the Property Title
After filing the Notice of Civil Claim, the lien claimant must register a certificate of pending litigation (CPL) at the Land Title Office against the specific property. The CPL preserves the lien’s effect on title throughout the court proceeding and must be registered within the one-year enforcement window.
A CPL is a Land Title Act instrument that warns anyone searching the property title that litigation affecting the property is active. The CPL prevents that outcome by creating a visible title encumbrance tied to the active court proceeding. The Land Title and Survey Authority of British Columbia (LTSA) processes the CPL registration against the property’s parcel identifier (PID). Both the original lien registration (CBL) and the CPL appear as separate charges on the property title.
To register a CPL, the claimant files a CPL form with the LTSA alongside evidence of the filed Notice of Civil Claim. The filing fee and procedural requirements follow the Land Title Act. The CPL registration must occur within the same one-year window as the Notice of Civil Claim. The date the CPL is registered with the LTSA, not the date it is prepared or submitted, determines whether the deadline is met. Claimants who file the court claim in the final days before the one-year deadline must account for LTSA processing time when registering the CPL.
Once a CPL is registered, the builders lien does not expire at the one-year mark. The lien right remains active for the duration of the court proceeding, which can run for months or years depending on the complexity of the dispute. A property owner facing an active CPL who wants to sell or refinance must either resolve the underlying payment claim, obtain a court order permitting a sale with proceeds held in trust pending the litigation outcome, or post security under section 24 of the Builders Lien Act to cancel the lien from title while the dispute continues.

The One-Year Enforcement Window Under Section 33 of the Builders Lien Act
Section 33 of the Builders Lien Act extinguishes a builders lien automatically if the claimant does not file a Notice of Civil Claim and register a CPL within one year of the lien’s registration date. No extension is available, no court has discretion to waive the deadline, and no agreement between the parties pauses the clock.
The one-year period begins on the date the lien is registered at the Land Title Office, not the date the work was performed, the invoice was issued, or the payment dispute arose, and regardless of the size of the unpaid amount, the strength of the underlying claim, or the status of any settlement negotiations.
BC courts treat the section 33 deadline as jurisdictional. There is no equitable remedy for a claimant who misses the window, no hardship argument that extends it, and no mechanism for the parties to agree to pause or extend the limitation period. In practice, many builders lien disputes resolve before the one-year deadline because the registered lien creates immediate pressure on the property owner. When negotiations stall or the owner goes silent, the claimant must file, regardless of whether a deal seems close. Waiting for a settlement that arrives after the deadline extinguishes the lien and eliminates the claimant’s most effective enforcement tool.
A full breakdown of how the one-year period interacts with lien expiry, title clearance, and the difference between the legal right expiring and the title registration persisting is covered in our guide to how long a builders lien lasts in BC.
Enforcing After Contract Abandonment or Termination
When a construction contract is abandoned or terminated before substantial completion, the 45-day lien filing window opens on the date of the abandonment or termination, and the one-year enforcement period runs from the lien registration date regardless of the circumstances that triggered the filing.
Abandonment and termination create factual complexity that straightforward completions do not. When a project is abandoned mid-construction, the claimant must establish the value of work completed to the point of abandonment, document the amounts invoiced and unpaid, and address disputes about whether the abandonment resulted from the owner’s failure to pay or the contractor’s failure to perform. These factual disputes do not pause the enforcement deadline. The Notice of Civil Claim must be filed within one year of lien registration.
For subcontractors and suppliers, the abandonment date that matters is the last date they personally performed work or delivered materials on the project, if the owner did not engage a head contractor, or the date the head contract was completed, abandoned or terminated, if the owner engaged a head contractor. A subcontractor who finished its scope one month before the head contractor walked off the site has a 45-day window running from the head contractor’s last day of work. But the subcontractor’s one-year enforcement period runs from the date its own lien was registered, calculated independently from the contractor’s timeline. The Builders Lien Act on BC Laws sets out the full framework for lien rights arising from abandonment and termination in sections 20, covering the triggering events and each party’s rights in the construction chain.
Subcontractors and Suppliers: The Head Contract Trap, Same Court Process
Subcontractors and material suppliers in BC hold independent builders lien rights, but their deadlines are structurally bound to the project’s overall timeline, rather than being calculated solely from the last date they performed work or supplied materials. Where a head contract exists, a subcontractor’s 45-day window to file is triggered by events affecting the head contractor, not their individual subcontract.
A subcontractor who completes its scope of work three weeks before the head contractor reaches substantial completion must still look to the status of the head contract. Unless a formal Certificate of Completion is issued specifically for that subcontract, the subcontractor’s 45-day window will not open until the head contract is completed, abandoned, or terminated. A subcontractor who stops work early because the contractor stopped paying faces a significant calculation risk. If their walk-off coincides with the total abandonment or termination of the head contract, the clock triggers; otherwise, they remain bound to the head contract’s ultimate completion date. The same calculation applies to material suppliers.
The statutory connection between subcontractor and supplier lien rights and the head contract is one of the most frequently misunderstood features of the Builders Lien Act. A subcontractor cannot rely on the head contractor’s lien to protect its own payment claim. If the contractor’s lien is registered and the subcontractor’s 45-day window passes without a filing, the subcontractor has no lien right, regardless of what the contractor does in court. The subcontractor’s secured claim is simply gone. The relationship between subcontractor lien rights and the statutory holdback that property owners must retain to protect against exactly this scenario is covered in ATAC LAW’s guide to builders lien holdback obligations in BC.
Once a subcontractor or supplier registers its lien, the enforcement procedure is identical to the contractor’s process: file the Notice of Civil Claim in BC Supreme Court, register the CPL, serve all defendants, and proceed to judgment. The court considers each claimant’s contribution and entitlement separately. Multiple claimants can participate in the same enforcement proceeding, with the court allocating available funds or security among competing claims according to the priority rules in the Builders Lien Act.
What Happens When You Miss the Enforcement Deadline
A lien claimant who misses the one-year enforcement deadline loses the lien right permanently. Section 33 of the Builders Lien Act extinguishes the lien by operation of law, with no exception, no extension, and no ability to refile for the same work or materials. The only remaining legal path is an unsecured breach of contract claim in BC Supreme Court.
The practical consequences of losing lien rights are significant. A breach of contract judgment does not attach to the property. It produces a personal judgment against the debtor, enforceable only against the debtor’s general assets. A registered lien, by contrast, creates a charge against real property that blocks sales and refinancing and forces the owner to address the claim directly or accept a permanent encumbrance on title. Losing the lien means losing that leverage, permanently.
The expired lien registration does not disappear from the property title automatically. The lien right is extinguished the moment the one-year window closes without a filed enforcement action, but the title entry remains until the property owner applies for formal cancellation under section 25 of the Builders Lien Act. The owner must provide evidence to the Land Title Office Registrar that the lien was registered more than one year ago and that no enforcement action was commenced within that period. Until that application is made, the expired lien continues to appear on the title and creates the same practical barriers for the owner as a live lien: lenders, buyers, and title insurers treat registered charges cautiously regardless of their legal status. The full cancellation procedure, including the Registrar application process and the contested court cancellation route, is set out in ATAC LAW’s guide to how to remove a builders lien in BC.
A claimant who realizes the enforcement deadline is approaching has one priority: file the Notice of Civil Claim and register the CPL before the date passes. Settlement negotiations should continue in parallel, not in place of filing. The cost of commencing enforcement and then reaching a settlement before trial may be substantially lower than the cost of permanently losing lien rights. The lien right is the claimant’s leverage. Filing preserves it. Waiting gives it away.
Frequently Asked Questions
What is a certificate of pending litigation (CPL) and why does a lien claimant need one?
A CPL is a Land Title Office instrument registered against a property title to alert all parties that active litigation affecting the property is underway. For builders lien enforcement, the CPL keeps the lien’s effect on title alive throughout the BC Supreme Court proceeding. Without a registered CPL, the lien right expires after one year even if a Notice of Civil Claim was filed in court. Both the Notice of Civil Claim and the CPL must be completed within the one-year enforcement window.
Can a property owner cancel a builders lien while enforcement proceedings are active?
Yes. Under section 24 of the Builders Lien Act, a property owner can apply to court to cancel a registered lien from title by posting security, usually equal to the claimed lien amount plus a reasonable estimate of costs, subject to the court’s satisfaction. Once the security is posted and the court order is granted, the lien is cancelled from title before the dispute is resolved through the court proceeding. This allows the owner to sell or refinance the property while the underlying payment claim works through the court process.
Does a subcontractor have to wait for the head contractor to enforce before filing its own court action?
No. A subcontractor holds independent lien rights under the Builders Lien Act and can commence its own enforcement action in BC Supreme Court within one year of its own lien registration date, regardless of what the head contractor does. A subcontractor who relies on the contractor to protect its claim risks having its lien extinguished if the contractor does not act or does not include the subcontractor’s claim in its own proceedings. Independent filing is the only safe approach.
Can the parties agree to extend the one-year enforcement deadline?
No. The one-year enforcement period under section 33 of the Builders Lien Act is a strict statutory deadline that cannot be extended by agreement between the parties, by court order, or by any equitable remedy. An agreement to extend the deadline has no legal effect. If the claimant does not file the Notice of Civil Claim and register the CPL within one year of the lien registration date, the lien is permanently extinguished regardless of any agreement made between the parties.
Can you negotiate a settlement after filing the enforcement action?
Yes. Filing the Notice of Civil Claim and registering the CPL does not prevent the parties from negotiating a settlement at any point before or during trial. The majority of builders lien enforcement actions in BC resolve through negotiated payment before a trial date is reached. Filing the enforcement documents before the one-year deadline protects the claimant’s legal position while settlement discussions continue. A claimant who files and then settles pays only the costs of filing and initial legal work. A claimant who waits for a settlement that does not materialize in time loses the lien right entirely.
Builders lien enforcement in BC requires precise timing, correct court documents, and an understanding of how the enforcement process applies differently to contractors, subcontractors, and material suppliers. Whether you are approaching the one-year enforcement deadline, navigating an abandonment scenario, or responding to a lien registered against your property, the construction lien lawyers at ATAC LAW advise clients across British Columbia on enforcement strategy, court procedure, and deadline management.
