Is every Factor K charge improper?

No. Some charges are legitimate. Legal review verifies if classification, applied parameters and calculation memory are adequate to the concrete case.

My company has paid this for years. Can it still be reviewed?

Yes. Long-term charging often increases the relevance of legal-technical review and may support correction and reimbursement claims within legal limits.

Can past payments be recovered?

Depending on the case, yes. Reimbursement may be claimed when improper payment is proven, observing applicable limitation periods.

What documents are needed for the initial review?

Usually SABESP invoices, supply contract, company documents and registration data.

Can this be challenged without filing a lawsuit?

Yes. Administrative challenge is often the first step and can be sufficient in many scenarios.

Can assistance be remote?

Yes. The firm provides remote and in-person assistance with continuous communication.
