Our policy is to not charge upfront payment. We work via success only. You only pay when we achieve results for your case.
We are a registered, licensed company operating on a success-based model only. Your success is our success. No hidden fees, no upfront costs.
In Swiss internet fraud recovery cases, our no-upfront-payment arrangement allows you to initiate legal action without any initial financial outlay. We cover all costs associated with your case, including legal fees, administrative expenses, and any related charges. Our cases typically resolve through direct negotiation and settlement between parties, operating outside the formal court system.
We carefully evaluate each client's case information and assess its viability before accepting representation. We only take on cases where we have high confidence in successful resolution, ensuring that our time and resources are invested in matters with strong prospects for recovery.
For approved clients with high success probability, we handle all case-related costs without upfront payment. Our fee is a pre-agreed amount that varies by case and becomes payable only after successful resolution. This model aligns our interests with yours - we succeed only when you succeed.
Our selective case evaluation process ensures we work only on matters with strong recovery prospects. Due to our high success rate, we can confidently cover all costs for approved clients. Under Swiss law, a modest base fee must be included in our agreement, which is due only after case resolution. If recovery is ultimately unsuccessful, you are responsible only for this pre-agreed minimal fee - not full hourly or standard legal fees. This structure provides significant financial protection while ensuring compliance with Swiss legal requirements.
