A unified scheme for the extension of credit no. Usually banks approach to each borrower individually, taking into account its financial position, term and type of loan, as well as the reliability of the client.
In order to get a deferment of payment or extend a loan agreement, contact the Bank with a written statement about the impossibility of repayment of the loan with the reasons. Almost all banks provide this opportunity not only in the case of loss of borrower's work or reduction of income, but in the case of serious illness of the client or its close relative, death of a loved one, loss of property, e.g. fire or flood.
When you extend the loan the term of repayment is increased, therefore, the monthly payment decreases. However, always keep in mind that at the time of renewal you will have to pay the Bank interest and, therefore, the overpayment on the loan in General will be more. Because the loan term is longer, so you'll need to give the Bank a large sum of interest for using the money. You can defer only the principal repayments.
After acceptance by Bank of the positive decision on the extension you will be asked to sign an additional agreement to the loan agreement. It will contain new loan conditions: period of extension, the final maturity date of the debt, the amount of the monthly payment, including principal and interest.
Be prepared for the fact that in some cases at the request of the borrower to extend the term of the loan, banks require additional collateral, for example, the surety or bail. After all, they understand that the financial condition of the borrower has deteriorated, and hence the risk of default of debt increased. Therefore, the hedging banks agree to such measures.
If you are in a situation when the possibility to pay no credit, don't despair. After all, banks are interested in rollover as much as you do, because this solution helps to avoid lengthy proceedings and resolve the conflict in court.
