Disputes are involved in a complex process that may involve different time limits. Typically, disputes that reach the chargeback stage will take between 30 days to 45 days to be resolved. However, the time limit may extend, depending on the severity of the dispute and how far it is processed in the dispute lifecycle.
For example, Visa intends to have their disputes revolved within 31 days from the date the merchant received notice of the dispute. But a cardholder has 30 days to file for pre-arbitration. If the file is accepted, dispute resolution may take up to an additional 30 days, depending on when the merchant submits their pre-abritration response.
