A loan guarantee, in finance, is a promise by one party (the guarantor) to assume the debt obligation of a borrower if that borrower defaults. A guarantee can be limited or unlimited, making the guarantor liable for only a portion or all of the debt.
A guarantee can be an individual or the lender can obtain a collateral security from the borrower
In the event that your guarantor is able to technically pay, but decides not to when they have been called upon to do so, then they are breaking the contract that they signed to with the lender and borrower. ... If no payment is made, the lender has the legal right to start a court order in order to retrieve the debt.
As the name suggest, equitable mortgage is created by the borrower in favour of the lender by deposit of title deed of immovable property as security to a lender until the loan is fully repaid. This creates a charge on the property, though no legal procedure is involved.
