A cash loan is a loan that the bank grants to the customer, provided that it is repaid in installments specified in the previous agreement. The funds incurred in this way can be used for various expenses. Unlike a loan, e.g. a mortgage, the liability is not secured by real estate. When borrowing a small amount, banks usually do not require security, although in some variants it is required in the form of a surety, promissory note or declaration of submission to enforcement.
