If a security agreement includes commercial property as collateral, the lender may file a UCC-1 declaration that serves as a pledge right in the property. A guarantee contract refers to a document that presents a lender with a protective interest for a given asset or immovable property that is mortgaged as collateral. The conditions shall be laid down at the time of the establishment of the security agreement. Security agreements are a necessary part of the business world, because without them, lenders would never grant loans to certain companies. In case of delay of the borrower, the mortgaged guarantees can be confiscated and sold by the lender. § 5.13 No assignment of warranties; Links. In the absence of the prior written consent of the agent, the borrower may under no circumstances acquire, create or authorize security interests, fees or charges or other interests in any of its other immovable property for the benefit of a holder (or related business of such a holder) of a percentage or more of its equity securities. . . .
