Arbitration Of Subcontractor Claims
Arbitration of Subcontractor Claims
Subcontractor claims arise when subcontractors seek to recover payments, variations, delay costs, or damages under construction or engineering contracts. Often, disputes arise between subcontractors and the main contractor or employer, and are frequently resolved through arbitration, especially in large-scale or international projects where arbitration is preferred over litigation.
Arbitration provides a neutral, expert-driven forum, often faster and more flexible than court litigation, with confidentiality and enforceability advantages under instruments like the New York Convention.

- Contemporaneous Records
- Keep accurate records to prove additional work, delays, or disruption.
- Dispute Resolution Clause
- Clearly define arbitration rules, governing law, and seat to avoid procedural challenges.

Conclusion

Well-drafted subcontracts with clear arbitration clauses, robust record-keeping, and proactive claim management increase the likelihood of successful recovery for subcontractors.
