CIPS stresses that clear verbal confirmation is required for agreements. Non-verbal signals (smiles, nods, handshakes) can indicate politeness or ambiguity but do not constitute binding agreement. Assuming agreement risks later disputes or misunderstandings. Skilled negotiators ensure closure by explicitly summarising agreed terms and documenting them. Non-verbal communication is supportive, not decisive, in contract negotiation contexts.
