Question:What should contractors and homeowners expect in small claims or court disputes over defective work and unpaid invoices?

Answer:In construction disputes between a property owner and a contractor, courts often focus on workmanship, contract terms, and whether the owner paid for properly completed work, with Small Claims Court matters commonly involving claims of defective work versus payment non-compliance. Evidence is critical because cases usually require documentation, photos, project records, and independent inspections or reports to assess trade standards and scope. Additional issues can arise beyond defective work, including unjust enrichment, consumer protection concerns, and failure to mitigate damages.

Disputes involving construction or renovation projects are often additionally troublesome as contractors and property owners alike will frequently begin a lawsuit without first obtaining proper legal advice.
