Bets are settled on the result at the end of 90 minutes play. In the event of abandonment before 90 minutes have been played then all bets will be void unless settlement is already determined.
Your account behavior and actions are also taken into consideration, and once your checks are valid and everything is legal and clear, your bet is settled. All this checking may take a long time, like an hour or longer, and as soon as everything is clear, Bet365 will consider your bet settled and pay you.
