# Contest an infringement claim

> Submit a written response and supporting documents disputing the claim. The first call moves the claim from `pending` to `contested`; subsequent calls append supplementary evidence without changing status. The `documents[]` you attach are aggregated across rounds in the claim's `contest_documents` field.

Only `pending` and `contested` claims accept new evidence. A `resolved` claim returns `400`.

Failure modes:
- `400` - the claim is `resolved` (terminal); cannot be contested further.
- `404` - the claim does not exist or is not against a DIR you own.
- `422` - `contest_notes` is too short (< 10 chars), too long (> 2000 chars), `documents` is > 20 entries, or a `document_id` is duplicated within the same submission.
