Key takeaways
  • A lien registered after the 60-day deadline (90 days for oil or gas well and concrete work) ceases to exist.
  • A registered lien ends after 180 days unless the claimant starts an action and registers a certificate of lis pendens, and the often-repeated two years is a different rule.
  • As an owner you can serve a 30-day notice to commence an action, or give security or pay money into court, and once an application to remove the lien from title has been served, a party can also serve a notice to prove the lien.

Finding a lien on your land title after a renovation or build is stressful. The law that governs it was once called the Builders' Lien Act. It is now the Prompt Payment and Construction Lien Act, so older guides may use the old name.

A lien does not last forever, and you are not powerless. This article explains the time limits, clears up the common belief that a lien lasts two years, and sets out the tools an owner has to get it off title.

This article covers the law of Alberta.

How long a contractor has to register a lien

For materials, the registration period ends 60 days after the last materials are furnished or the contract to furnish them is abandoned. For a contractor or subcontractor, it ends 60 days from the day the contract or subcontract is completed or abandoned; services and wages also run 60 days from completion.

The period is 90 days instead of 60 for improvements to oil or gas wells and for concrete-related improvements. Correcting something that was improperly done or left out does not extend the deadline.

A lien that is not registered within the time limit ceases to exist. If a lien appears on your title, check the dates of the work first.

How long a registered lien lasts: 180 days, not two years

A registered lien ceases to exist unless, within 180 days from the date it is registered, the claimant starts an action to enforce it and registers a certificate of lis pendens. A certificate of lis pendens is a notice on title that a court case about the land is under way.

The two-year figure comes from a different rule. If no trial has been held within 2 years from registration of the certificate of lis pendens, an interested party may apply to have the certificate vacated and the lien discharged. A lien continued by lis pendens lasts until the proceedings are concluded or the certificate is discharged, whichever is later.

The owner's tools for removing a lien

Two exceptions matter. The rule in section 45(1) does not apply where security is given or payment is made into court and the lien is removed from title. Also, once a court has removed the lien in that way, the claim against the money or security does not end just because no lis pendens was registered or no action was started within 180 days.

Discharge by the lienholder or by court order

The Registrar must cancel a lien, in whole or in part, on a prescribed-form notice from the lienholder or agent that the lien has been satisfied, or on proof satisfactory to the Registrar that the lien has ceased to exist. Partial cancellation needs a form describing the part that was satisfied. Discharge, in whole or in part, is made on Form 14.

The Registrar must also cancel the lien and any lis pendens certificate on a certified court order cancelling the lien, or on a court clerk's certificate that the amount was paid into court or the land was sold to satisfy the lien.

Holdback, and what to do next

Holdback connects to all of this. An owner must retain 10% of the value of the work actually done for 60 days, counted from the certificate of substantial performance if one is issued, or otherwise from completion of the contract. The period is 90 days for oil or gas well and concrete-related improvements. Paying the major lien fund after 60 days from completion discharges the owner's liability unless a statement of lien is registered.

The statute was renamed and amended, so sections 41, 43 and 46 should be re-checked against the current version before you rely on any deadline. A lawyer can confirm how the rules apply to your facts.

Frequently asked questions

Does a builders' lien expire after two years in Alberta?

Not under that rule. A registered lien ceases to exist after 180 days unless an action is started and a certificate of lis pendens is registered. The two-year figure applies to applying to vacate a lis pendens when no trial has been held.

What happens if the contractor registered the lien too late?

A lien not registered within the time limit ceases to exist. The usual limit is 60 days, or 90 days for oil or gas well and concrete-related improvements.

Can I force the contractor to sue?

Yes, in many cases. You can serve written notice on the registered lienholder to commence an action, but this does not apply where security has been given or payment made into court and the lien has been removed from title. If the lienholder does not start an action and register a certificate of lis pendens within 30 days of service, the lien ceases to exist.

How does paying money into court help?

The court may order the lien removed from title when security is given or money is paid in, and that money or security then stands in place of the land. The lienholder's claim continues against it rather than against your property.
