            <p>
            mail_debt_date，你方与出借人mail_lender_name签订《借款合同》，并在我处对该合同办理了具有强制执行效力的债权文书公证【公证书编号：mail_notarization_cod】。合同约定：借款人mail_debt_name向出借人mail_lender_name申请借款人民币mail_contract_amont元，借款期限mail_contract_deadline。
            </p>
            <p>
            现出借人向本处提出申请称：其于mail_statement_date以银行转帐方式给付mail_debt_name借款共计mail_contract_amont元，现借款期限已到期，但是mail_debt_name未能依约还款，尚欠本金mail_dept_principal元，利息给付至mail_dept_endate。故依合同约定向公证处申请出具《执行证书》，请求确认执行标的：一、借款本金mail_dept_principal元；二、借款利息，自mail_dept_interest_date起至还款之日止，按月利率mail_late_charge%计算。
            </P>
            <p>    
            现与你方核实上述借款的还款情况，请收到此函后三个工作日内以书面形式回复、或者亲自到我处向承办公证员如实陈述履行合同的情况，并提供相关证据。若到期没有回复或未能提供证据，则视为你方对上述债权主张无异议，我处将按上述合同约定及出借人主张的债权金额，出具执行证书。之后，出借人可以不经诉讼，直接向有管辖权的人民法院对你方申请强制执行。
