The REDESCA began its operations in September 2017 with funding mainly from the Spanish Fund at the OAS, supplemented by contributions from Swiss cooperation and voluntary contributions from Argentina, Peru, Paraguay, and Uruguay, originally intended for one year. The Special Rapporteurship does not receive funding from the Regular Fund of the OAS or the IACHR, so part of its work is focused on securing resources for its operation.

At the beginning of 2024, REDESCA has the support of the Government of Norway - through its Embassy in Mexico City - and Spain - through the Spanish Fund for the OAS (FEPO) -, with whom new cooperation agreements have been successfully concluded. A joint project with the Executive Secretariat of the IACHR funded by the Pan American Development Foundation (PADF) has also been finalized. In addition, the support received from the O'Neill Institute for National and Global Health Law at Georgetown University, and the non-governmental organization Women in Informal Employment: Globalizing and Organizing (WIEGO), among other supports received, has been significant.

Regarding the accountability of the Office, all funding received is subject to performance and results reports that are required by the counterparts with the intervention of the OAS Project Management Monitoring Department, within the framework of project management and administrative tasks carried out by the Executive Secretariat of the IACHR, in accordance with the REDESCA's Contingency Plan.
