Is it permissible to request another check from AdSense to disavow haram money after the first check has expired?

You did well by ceasing to deal with the the company. There is no blame upon you for requesting another check to cash it and dispose of it by giving it to be used for the benefit of Muslims, the poor, and the needy. You will be rewarded for your good intention. The check amount should not be left with the company so that it does not combine unlawful compensation with what is compensated for. The price of wine, the dowry of a prostitute, and the fee of a soothsayer are to be spent for the benefit of Muslims if the sinner has already received the compensation.
