# Inquiry participant identity proposal
Status: proposed
Status: implemented on 2026-09-13
Scope: every user, expert, FileMaker, and call-center inquiry flow
Persian version: [inquiry-participants-proposal.fa.md](./inquiry-participants-proposal.fa.md)
## Implemented interface
The role fields and optional `vehicle` object shown below are accepted directly in every existing inquiry request body. This covers V2 user and expert/registrar mirror initial forms, V3 expert flow, V4/V5 FileMaker flows, V6 call-center flow, and the one-shot in-person completion paths. Plate and VIN routes share the same participant rules.
Existing flat fields remain accepted during migration. Responses and file-detail views for operational actors expose normalized `participants`, `participantRoles`, `vehicle.registrationState`, and `vehicle.previousPlateId` where available.
## Problem
The current inquiry contract mainly models a driver and a value named `insurer`. That is incomplete and the name is misleading: a person is the **policyholder**; the **insurer** is the insurance company.
Each vehicle-side `Party` can have these identity roles:
| Case type | Required roles |
| --- | --- |
| `THIRD_PARTY` | Driver, vehicle owner, third-party policyholder |
| `CAR_BODY` | Driver, vehicle owner, third-party policyholder, car-body policyholder |
| Case type | Required roles |
| ------------- | ---------------------------------------------------------------------- |
| `THIRD_PARTY` | Driver, vehicle owner, third-party policyholder |
| `CAR_BODY` | Driver, vehicle owner, third-party policyholder, car-body policyholder |
One person may hold several roles, but the system must not assume that they do.

`carBodyPolicyholder` is forbidden for `THIRD_PARTY` and required for `CAR_BODY`. A role is either a new person's identity or a `sameAs` reference, never both. The backend should normalize this input into unique participants plus role assignments.
For Driver, `hasDrivingLicense` is required. When it is `true`, both `licenseNumber` and `licenseType` are required; when it is `false`, the licence inquiry is intentionally skipped.
## Recent ownership transfer and previous plate
Participant roles and vehicle identifiers are separate concerns. When a vehicle has recently been sold or purchased, the current official record or policy may still be connected to its previous plate. Model this explicitly instead of replacing the current plate:
