Prior to entering into a loan agreement, the "borrower" first makes representations about his affairs surrounding his character, creditworthiness, cashflow, and any collateral that he may have available to pledge as security for a loan. These representations are taken into consideration and the lender then determines under what conditions (terms), if any, they are prepared to advance money.
The loan deferment process involves contacting the lender, submitting a deferment application, and undergoing the application process. The actual process can vary by lender. Other factors taken into account include the borrower's credit history, type of loan, and number of payments being deferred. Approval can take less than 24 hours to several weeks.
Loan agreements fall into two main types, according to the type of lender, and according to the type of facility. With respect to the type of lender, there are bilateral loans and syndicated loans. Syndicated loans are provided by groups of lenders, and their structuring and arrangement, as well as their administration, are carried out by more than one bank, commercial or investment ones, and the lending banks are also referred to as arrangers.

This means as a student you and your parents would need to sign on the loan agreement agreeing to repay the loan.
