# Register receivables as collateral

> How a contract effect on card receivables is registered, and how the settlement reaches your institution through Lerian.

Make sure the receivable given as collateral is paid to the account your institution indicates, and check later that each expected amount arrived.

<Note>
  This flow is a suggested reading of the Núclea and BACEN manuals. The manuals prevail over this page. Your institution, as the participant, validates the flow and implements it on the Lerian APIs. See [how to read the diagrams](/en/diagrams/introduction).
</Note>

## Participants

***

* **Your institution.** The participant that runs the journey and books its effects.
* **Lerian.** Lerian SLC, Lerian SILOC and Lerian SPB. They exchange the messages with Núclea and STR, and expose the API and the events your institution uses.
* **Receivables registrar.** Records the contract effect (lien, fiduciary assignment or change of holder) on the receivable.
* **Acquirer.** Pays the merchant's card receivables and reports each settlement to Núclea.
* **Núclea.** Runs the SLC and SILOC clearinghouses and their settlement windows.

| # | From | To | Message | Lerian API | What happens |
| - | - | - | - | - | - |
| 1 | Your institution | Your institution | Internal step | | Grant the credit to the borrower and select the receivables that secure it. |
| 2 | Your institution | Lerian | Lerian API | Pending | Ask Lerian to register the contract effect: a lien, a fiduciary assignment or a change of holder. |
| 3 | Lerian | Receivables registrar | Registrar API | Pending | Lerian registers the contract effect at the receivables registrar. |
| 4 | Receivables registrar | Lerian | Registrar API | Pending | The registrar confirms the registration. |
| 5 | Receivables registrar | Acquirer | Between other parties | | The registrar informs the acquirer of the new holder and of the payment account. |
| 6 | Acquirer | Núclea | `ASLC027/029/031` | | The acquirer reports each settlement to Núclea with the holder and the account that the contract effect set. |
| 7 | Receivables registrar | Lerian | Registrar API | Pending | The registrar sends the receivables schedule and the settlements, and Lerian reconciles them with the credits received. |

## How you know it finished

***

Every receivable in the schedule matches a credit received at the domicile, or opens an exception.
