Mortgage lawA mortgage is a legal instrument of the common law which is used to create a security interest in real property held by a lender as a security for a debt, usually a mortgage loan. Hypothec is the corresponding term in civil law jurisdictions, albeit with a wider sense, as it also covers non-possessory lien. A mortgage in itself is not a debt, it is the lender's security for a debt. It is a transfer of an interest in land (or the equivalent) from the owner to the mortgage lender, on the condition that this interest will be returned to the owner when the terms of the mortgage have been satisfied or performed.
HypothecHypothec (haɪˈpɒθɪk,_ˈhaɪpɒθ-; Hypothek, hypothèque, hipoteka, from Lat. hypotheca, from Gk. ὑποθήκη: hypothēkē), sometimes tacit hypothec, is a term used in civil law systems (e.g. the law of all of Continental Europe except Gibraltar) or mixed legal systems (e.g. Scots law, South African law) to refer to a registered non-possessory real security over real estate, but under some jurisdictions it may sometimes also denote security on other collaterals such as securities, intellectual property rights or corporeal movable property, either ships only (ship hypothec) as opposed to other movables covered by a different type of right (pledge) in the legal systems of some countries, or any movables in legal systems of other countries.
Floating chargeIn finance, a floating charge is a security interest over a fund of changing assets of a company or other legal person. Unlike a fixed charge, which is created over ascertained and definite property, a floating charge is created over property of an ambulatory and shifting nature, such as receivables and stock. The floating charge 'floats' or 'hovers' until the point at which it is converted ("crystallised") into a fixed charge, attached to specific assets of the business. This crystallisation can be triggered by a number of events.
