A legal document, usually in writing, giving details of a formal legally binding agreement, between two or more different people or groups. To be legally binding it must contain certain elements: it must contain an offer made by one party and accepted in its entirety by the other, it must include some form of consideration whether it be money, goods or services, and it must be properly signed by all parties to it, and dated.

A common clause in contracts that essentially frees both parties from liability or obligation when an extraordinary event or circumstance beyond the control of the parties such as war, strike, riot, crime, or an event known as an act of God (such as a hurricane, flooding, earthquake, volcanic eruption etc.), prevents one or both parties from fulfilling their obligations under the contract. In practice, most force majeure clauses do not exclude a party’s non-performance entirely, but only suspends it for the duration of the force majeure event.

A formal promise by one party (the guarantor or surety) to another party (the creditor) to accept responsibility of a third party’s (the principal debtor) debt, if that third party cannot or refuses to pay it.

Also referred to as a mortgage loan, is used by purchasers of real property to raise capital for the purchase, or by existing owners to raise funds for any purpose while putting a lien on the property being mortgaged. The loan is secured on the borrower’s property, putting in place a legal mechanism which will enable the lender to take possession and sell the secured property to pay off the loan in the event that the borrower defaults on the loan or otherwise fails to abide by its terms.
