Unvollständige Lien Waiver- und Dokumentationspflichten; Zahlungsausfallrisiko

2 verified sources

Definition

Before releasing progress payments, German principals (Auftraggeber) require proof that all subcontractors and suppliers have been paid (Nachweis der Bezahlung von Nachunternehmern). This requires: (1) Statutory declarations (Eidesstattliche Versicherung), (2) Bank transfer receipts, (3) Payroll records for labor. Contractors frequently submit incomplete or falsified waivers, claiming payment when suppliers/subs haven't actually been paid. This creates: (a) Nachunternehmer liens against the project (Retentionsrecht), (b) Withholding of final payment by principal, (c) Litigation and payment delays. Additionally, missing payroll documentation triggers labor law violations (Arbeitsrecht) and BG (occupational insurance) penalties.

Key Findings

  • Financial Impact: €50,000–€500,000 average litigation/settlement per dispute; 6–12 month payment hold on disputed invoices; 3–5% final payment withholding; cumulative annual loss for mid-sized contractor: €100,000–€500,000
  • Frequency: Per-project risk; 10–20% of projects experience waiver-related payment disputes
  • Root Cause: Manual waiver compilation; lack of verification mechanism; no real-time subcontractor payment tracking; missing audit trail
