English to Spanish Bus/Financial Insurance Reinsurance Agreement

The term appears in the following context:

All documentation in respect of the issuance of the Local Policy, premium invoices and insurance certificates are to be produced in accordance with the Producing Office business referral instruction and issued in accordance with the Service Standards set out in this document.

(Business referral understood as business referred to an Insurer by way of an Agreement)

I'm not sure of the exact (coined) translation in Spanish: ¿derivación de negocio? ¿remisión de negocio?

Many thanks in advance
