# Update Associated Person

> Partially update an associated person and recompute onboarding requirements

Partially updates an associated person and recomputes onboarding requirements. All fields are optional; omitted fields are left untouched. Contact/display corrections may apply immediately; identity, role, ownership, signatory, and address changes can require additional verification review and may reset the person's hosted verification.

<Warning>
  Updates are rejected with `422` once the account's `kyc_status` is terminal (`approved` or `rejected`).
</Warning>
