The 2019 prompt-payment amendments (2019, c. 12) and 2022 adjudication amendments (2022, c. 43) are listed as not proclaimed in the official statute table checked for this edition. The government's implementation page describes regulations still being developed. The existing Builders' Lien Act continues to govern current lien and holdback rights. Do not turn anticipated regulation-based payment periods into current legal deadlines.
Existing lien and holdback obligations have their own scope and status. Read the relevant topic before using a figure.
Deadlines and reference points
Read the trigger and conditions with the figure. These are statutory reference points, not calculated dates for your project.
- Deemed-proper review windowNot operative — regulations required
The prompt-payment framework is not operative. Do not use a working-model number as a current obligation. Existing contract, lien and holdback duties remain separate.
Read the source and commencement status
Present billing requirements and future legislation
The amendments contemplate a proper-invoice system with details to be prescribed. Ontario-derived 28-day, 14-day or seven-day assumptions are not a substitute for Nova Scotia regulations and commencement. Continue to follow the actual contract's billing requirements and preserve invoice, work and delivery records; confirm the eventual transition and prescribed particulars before using a statutory proper-invoice checklist.
Build a complete invoice record
Record the supplier's identity and contact details, the contract or purchase-order reference, billing period or milestone, work and material descriptions, quantities where relevant, amount, tax, payment terms and payment recipient. These are practical preparation details, not a claim that every item is currently prescribed by the pending statute.
Keep completeness separate from the merits
A document may comply with a contract's invoice requirements while the value or quality of the work is disputed. Conversely, an incomplete invoice does not erase independently existing contract, trust, lien or holdback rights. Identify the actual reason for a response rather than treating all objections as the same notice.
Delivery, revisions and transition
Retain the sent version, attachments, recipient and delivery evidence. If a correction is needed, document what changed and why; do not silently replace an earlier invoice or assume a revised date extends any existing right.
When the new rules commence, check which contracts they cover, the permitted delivery methods, additional prescribed information and any restrictions on approval or certification conditions. Do not adopt another province's deemed-proper-invoice rule.
Apply the current Builders' Lien Act and Interpretation Act to the actual supply, certificate or completion event. Learn's calculators do not calculate Nova Scotia deadlines. Future regulation-based periods remain unprescribed here rather than being borrowed from Ontario.
Questions about this guide
Is Nova Scotia's prompt-payment framework in force?
The 2019 prompt-payment amendments (2019, c. 12) and 2022 adjudication amendments (2022, c. 43) are listed as not proclaimed in the official statute table checked for this edition. The government's implementation page describes regulations still being developed. The existing Builders' Lien Act continues to govern current lien and holdback rights. Do not turn anticipated regulation-based payment periods into current legal deadlines.
Can I use another province's statutory deadlines or forms?
No. Commencement, project scope, local regulations and the applicable contract must be checked. A model period or form is not a substitute for an operative local rule.
Do existing lien and holdback obligations still apply?
Section 13 of the current Builders' Lien Act generally requires 10% of the value of the work, services and materials, retained for 60 days after substantial performance. Section 13(1) defines that event by readiness or actual use and the cost of remaining completion or correction, not simply an invoice date. A separate 10% fund applies to remaining work under section 13(3). These duties are independent of the unproclaimed prompt-payment amendments. Section 24 generally uses 60 days: completion or abandonment for a contractor or subcontractor, last furnishing or placing for materials, completion of services, or last work for wages. Section 24(5) provides a special final-certificate branch for certain contractor claims. Check the specific category; do not calculate from an anticipated prompt-payment notice or an invoice due date.
Can Learn calculate these prompt-payment deadlines?
No active prompt-payment dates are generated for this jurisdiction. These guides distinguish current obligations from future legislation.
