Because the AdSense system doesn't know that an account owner is deceased, the system will automatically continue to make payments using the payment settings in the AdSense account. If you are the rightful heir and need payment of accrued earnings to be redirected, please upload the requested documentation electronically here or fax or mail your request and appropriate legal documentation to:
