Chargeback Legal Kit

Legal strategy and evidence pack for Visa/Mastercard disputes — recovery of funds for consumers (B2C) or defense of merchants/PSPs against chargeback attacks (B2B).

Who we assist:

B2C clients facing significant losses from fraudulent charges or “broker” schemes, as well as from PSPs, merchants, e-commerce businesses, and payment teams that require procedural legal protection against unjustified chargebacks.

What is legal support in chargeback matters?

Legal support within the Chargeback Legal Kit framework is a comprehensive set of legal and procedural actions aimed at recovering funds by disputing card payments (chargebacks) where there are reasonable grounds to consider a transaction unauthorized, erroneous, or fraudulent, as well as protecting merchants and PSPs from unjustified refund claims.

This is not simply filing a complaint with a bank — it is a procedural strategy grounded in a deep understanding of Visa and Mastercard’s internal rules, issuer/acquirer decision-making logic, and strict evidentiary requirements.

The chargeback process involves the cardholder, the issuing bank (the payer’s bank), the card scheme (Visa/Mastercard), the acquiring bank (the merchant’s bank), and the merchant/payment recipient.  Typically, the process unfolds as follows: the client files a dispute with the issuing bank; the bank conducts a preliminary review and, if justified, initiates a chargeback; the acquiring bank provides the merchant an opportunity to respond (representment); and, if necessary, the dispute escalates to arbitration within the card scheme.

Strict deadlines and technical evidentiary requirements govern each stage.

The core challenge lies in the complexity and opacity of Visa and Mastercard rules (including the Mastercard Chargeback Guide, Visa Core Rules, and Visa Product and Service Rules). These frameworks are extensive, technical, and effectively inaccessible to consumers. Banks rarely disclose detailed reasoning behind decisions or clarify applicable reason codes and evidence requirements. For merchants, the risks include financial losses, increased dispute rates, and potential termination of acquiring agreements.

The GOLAW team provides procedurally structured support: identifying relevant reason codes, building an evidence package aligned with card scheme requirements and internal bank standards, monitoring deadlines, preparing legally sound submissions, and supporting all stages — from initial dispute to arbitration, where necessary.

What we do

  • Qualification of transactions under applicable reason codes and verification of deadlines and procedural requirements under card scheme rules
  • Development of an evidence pack aligned with Visa/Mastercard standards and issuer bank requirements
  • Procedural submissions and escalation letters to issuing banks, acquiring banks, and PSPs

  • Strategy against friendly fraud and organized chargeback attacks
  • Negotiation/mediation support with merchants and preparation for litigation where necessary
  • Training of support and operations teams: documentation standards, procedures, client communication

Frequently asked questions

  • Does chargeback work in 100% of cases?

    No. Chargeback is a procedural mechanism with strict deadlines, evidence requirements, and complex internal decision-making processes. Success depends on multiple factors: reason code selection, quality of evidence, merchant position, and compliance with procedural rules. We increase the chances of success through proper qualification and professionally prepared evidence packages.

  • What transaction amounts justify legal support?

    For B2C clients — where losses are significant or involve multiple transactions requiring a structured approach. For B2B clients (merchants, PSPs) — where risk is systemic: high dispute rates, potential card scheme penalties, risk of acquiring termination, or organized chargeback attacks.

  • How long does the procedure take?

    Depending on the bank, case complexity, and number of representment/arbitration cycles. Typically, 6–12 weeks. Complex multi-round disputes may take longer. Strict adherence to deadlines at each stage is critical.

  • Is filing a police report necessary?

    In certain cases — particularly fraud-related reason codes — yes. A police report may strengthen the evidentiary position and demonstrate seriousness of intent. We advise when and how such reports should be properly filed.

  • What is friendly fraud and how can it be addressed?

    Friendly fraud occurs when a customer receives goods/services but initiates a chargeback claiming non-authorization or non-delivery. For merchants, this is a significant risk. Effective defense requires strong documentation: delivery confirmations, communications, IP logs, call records, proof of service usage. We help merchants build structured defense systems.

  • Can a bank’s decision be challenged?

    Yes. If the issuing bank rejects the initial dispute, possible strategies include: (1) resubmission with additional evidence, (2) escalation within the bank, (3) complaint to the regulator (NBU), or (4) court proceedings. The appropriate strategy depends on the specific circumstances and reasons for refusal.
