The draft may not be sent until the debtor has been sent a payment reminder, which sets a time limit of at least 10 days for payment of the claim or submission of remarks on the claim, and the time limit has expired. It is also possible to meet the above deadline by adding the deadlines for any multiple reminders or payment requests together if they have been sent before the draft. The draft can be protested for 14 days after it has been sent. The draft cannot be protested later than 60 days after it has been sent, unless otherwise agreed in writing with the debtor.
