Mortgage foreclosure law is the law that governs the process by which foreclosures can be used. In the housing market, foreclosures are a a proceeding that forces a mortgagor to forfeit their home due to non payment of mortgage. When the two parties enter into the loan, the lender receives this right, to foreclose, as part of their agreement. At first, mortgage foreclosure law required that unpaid mortgages could automatically result in repossession. However, newer laws have now given more liberty to the homeowner to pay back mortgage in time, prior to being foreclosed upon.

These laws, both federal and state, also specify a range of other requirements regarding foreclosures. On the federal level, two main mortgage foreclosure laws exist - bankruptcy laws and the Soldier and Sailors Relief Act of 1940. In each state, there are also laws that define the foreclosure process in more detail, including the time period for repayment and regulations on deficiency.
