A practice note about the security that can be taken (or arise) over freehold or leasehold property. This includes legal mortgages (also known as legal charges), equitable mortgages, fixed charges and floating charges. As the lender often takes security over property (also known as real estate) together with security over other assets owned by the borrower, the security interest created over the property may be contained within a global security document commonly referred to as a debenture.
