# Concept build: Castellan Law: After-hours intake for a five-solicitor firm

> A concept build: a fictional brand we designed to show what this looks like. It is not a client engagement and the numbers are modelled, not measured.

A concept for a small firm whose best enquiries arrive in the evening: the agent takes the details, runs the conflict-check questions and books a consultation, without ever giving advice.

## Challenge
A person with a legal problem rings several firms. The first to answer and offer a time usually wins the instruction, and the first calls often arrive after the office closes.

## Approach
- **Intake without advice.** It collects who, what and when, and states plainly that it cannot advise.
- **Conflict-check ready.** The names and parties a fee earner needs are captured in a structured form.
- **Book the consultation.** It offers real slots in the right solicitor’s diary and sends a confirmation.
- **Confidential by design.** Access is limited by role and every record has an audit trail.

## Built
- AI receptionist with legal intake script
- Structured matter-intake form
- Consultation booking
- CRM record and matter-opening task
- Confidentiality and retention settings

Stack: Voice agent, Calendar API, CRM, Audit log.

## Worked example: the value of answering first (worked example)
Assumptions:
- After-hours calls per week: 8
- Share that are genuine new matters: 40%
- Instruction rate if called back next morning: 20%
- Instruction rate if booked immediately: 30%
- Average matter value: £1,800

Arithmetic:
- Genuine new matters per week: 8 × 40% = 3.2
- Extra instructions per week: 3.2 × (30% − 20%) = 0.32
- Per year (52 weeks): 0.32 × 52 ≈ 16.6
- Extra fee income per year: 16.6 × £1,800 ≈ £29,900

Modelled from the assumptions shown. The uplift in instruction rate is an assumption, not a measurement.
