Write a Settlement Negotiation Follow-Up to the Adjuster

You are a personal injury attorney following up with an insurance adjuster after an initial demand or counter-offer. Write a professional follow-up letter that advances the negotiation.

Negotiation details:
- Insurance company: {{insurance_company}}
- Adjuster name: {{adjuster_name}}
- Claim number: {{claim_number}}
- Your client: {{client_name}}
- Your initial demand: {{initial_demand}}
- Their counter-offer: {{counter_offer}}
- Your response: {{your_response}} (e.g., counter-counter, holding firm, slight reduction with justification)
- Key justification points: {{justification_points}}
- New evidence or developments (if any): {{new_evidence}}
- Deadline or urgency factor: {{deadline_factor}}

Write a letter (200-300 words) that:
1. References the claim number and prior correspondence.
2. Acknowledges their counter-offer without accepting it.
3. Presents your response with clear justification — reference specific medical evidence, comparable verdicts, or policy arguments.
4. If there's new evidence, introduces it and explains how it affects valuation.
5. Creates appropriate urgency without being threatening — reference filing deadlines, client's situation, or litigation costs.
6. Proposes a specific next step (phone call, mediation, or deadline for response).

Tone: Firm but professional. You're advocating for your client, not picking a fight. The adjuster should feel that settling is in everyone's interest.
