A project dispute can threaten payment, schedules, and the business you built. Ghassemian Law Group represents California contractors, developers, and property owners in high-stakes construction litigation with a focused, evidence-driven approach.
Deadline-sensitive payment dispute?
Use CCL’s private-works lien readiness checklist to identify key project records, then request an intake-team case review. The tool is educational and does not determine lien rights or deadlines.
Most attorneys understand the law. Construction disputes also turn on schedules, subcontracts, change orders, and project records. Our managing attorney holds a physics degree and has spent 25 years in California construction disputes.
