Usage

What does default mean in loans? Default is the failure to meet one’s financial obligations, for example, when a borrower misses or stops making monthly loan payments. Default on a loan can make it difficult to get loans in the future and may have other serious consequences. If a person defaults on a home mortgage, the bank may foreclose on the loan and take over ownership of the property, to sell it in order to recoup as much of the unpaid portion of the loan as possible. The term not only applies to individuals, but also to businesses and governments that cannot pay back their debts. Default can also mean failure to account properly for money in one’s care.
