Challenges
Disputes involving construction or renovation projects are often challenging due to the many legal issues that typically apply within the realm of construction law. Common issues may involve the extent of, and quality of, evidence required, such as the need sometimes for an independent witness to inspect and provide a reports as to what workmanship was done correctly and what workmanship was done incorrectly thus whether the required workmanship standards were met. 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.
Furthermore, lawsuits involving construction or renovation projects commonly include legal issues that go beyond allegations of poor quality of work and also include legal issues such as quantum meruit disputes over the value of partially completed work, consumer rights concerns, mitigation requirements, and much more.
