Building Defect and Contractor Dispute Tasmania — Court Claim Guide

A contractor took a $6,000 deposit for a bathroom renovation and disappeared. A plumber's work started leaking within a month. A builder finished the job but the workmanship is so poor you need someone else to redo it. A sole trader completed three weeks of carpentry and the client stopped returning calls about the invoice.

Building and trade disputes are among the most common minor civil claims in Tasmania. They cut both ways — homeowners chasing contractors for defective work or missing deposits, and tradespeople chasing clients for unpaid invoices. Both sides use the same Magistrates Court process.

Homeowner Claims Against Contractors

If a contractor's work is defective, incomplete, or they've taken your money and abandoned the job, your claim is for the cost to fix the problem or the money you've lost.

Before filing in the Magistrates Court, Building Standards Tasmania (BST) recommends trying to resolve the dispute first. For a residential building dispute, you can lodge a Notice of Dispute with the Director of Building Control, who may arrange mediation. The Building and Construction Industry Security of Payment Act 2009 provides a separate adjudication process for payment claims.

BST mediation does not award money or force a settlement. If mediation fails or the contractor won't engage, the Magistrates Court is the next step.

What to claim:

• The cost of hiring another contractor to fix or complete the work (get written quotes)
• The deposit or progress payments made for work that wasn't done
• Costs incurred because of the defective work (emergency repairs, temporary fixes, accommodation if the home was uninhabitable)

Your total must be $15,000 or less for the minor civil claims process. If the defect costs more, you can abandon the excess to stay within the limit — but that permanently surrenders your right to the amount above $15,000.

Trade and Small Business Claims for Unpaid Invoices

On the other side, sole traders and small businesses use the same Magistrates Court process to recover unpaid invoices. A carpenter who completed a deck build, an electrician who rewired a switchboard, a cleaning company that serviced a commercial property — if the client won't pay, a minor civil claim is the formal collection mechanism.

Your claim is straightforward: you did the work, you invoiced for it, the invoice is overdue, and the client hasn't paid despite a formal demand.

The Demand Letter

For both sides of a building dispute, a letter of demand is the essential first step. Courts expect you to have given the other party a fair chance to resolve the matter before filing.

Homeowners claiming for defective work should include:

• A description of the work agreed and what was actually delivered
• Photos of the defects
• An independent quote for remediation
• A deadline (14–21 days) and the amount demanded

Tradespeople claiming for unpaid invoices should include:

• The original quote or contract
• Copies of invoices with dates and amounts
• A record of completion (signed job sheets, delivery receipts, photos of finished work)
• A deadline and the outstanding amount

Send the demand by registered post. Keep proof of postage — it becomes part of your court evidence.

Evidence for Building Disputes

Building disputes are evidence-heavy. The Magistrate decides based on documents, not impressions. Gather everything before you file:

• The contract or quote — written agreements, text messages confirming scope, email chains
• Invoices and receipts — what was paid, when, and for what
• Photographs — dated photos of the work (before, during, after)
• Independent expert reports — a qualified builder, engineer, or trade professional who inspected the defective work and can describe what went wrong
• Remediation quotes — written quotes from at least two other contractors for the cost to fix the problem
• Communication records — emails, texts, or letters showing attempts to resolve the dispute
• Licence and ABN records — confirm the contractor's registration status through BST or ABN Lookup

The independent expert report is often the difference between winning and losing a building defect claim. A Magistrate can assess a simple unpaid invoice, but evaluating whether waterproofing was done to standard requires a professional opinion.

Filing and the Court Process

File Form 1 (Claim and Notice to Defendant) at the nearest Magistrates Court registry. The filing fee is $147 for claims up to $5,000 or $284.20 for claims between $5,001 and $15,000.

Name the correct legal entity. If the contractor is a sole trader, name the individual person (check ABN Lookup). If they operate through a company, name the company with its ACN (check the ASIC register). Getting this wrong means you can't enforce a judgment even if you win.

After filing, serve the defendant — personal service, registered post, or a process server. They have 21 days to file a Form 4 Defence. If they don't, you can apply for default judgment using Form 21.

If they do defend, expect a conciliation conference before any hearing. Building disputes often settle at conciliation when both parties see each other's quotes, photos, and expert reports for the first time.
