Im Moj. An old friend of mine has unpaid debt with me amounting to 111+ thousand pesos. He doesn't have a signed promissory note but we have email threads regarding his debt. And in the email we have disagreement on the terms as he wants to settle it in a year but as creditor I want my money back the soonest time as I badly needed it for the hospitalization of my uncle. Is their any legal way I can push him to pay his debt or is their any case that I can file against him as he failed to pay for this month without notice.
