A Special Assessment District (S.A.D.) is a geographic area in which the market value of real estate is enhanced due to the influence of a public improvement and in which a tax is apportioned to recover the costs of the public improvement.
Void, voidable, and unenforceable contracts: (1) A void contract is one without any legal effect from the beginning. (2) A voidable contract is one that a party may elect to avoid or ratify. (3) An unenforceable contract is one otherwise valid but for which some defense exists extraneous to formation.
o Avoidable: A contract is avoidable if one of the parties has the option to terminate the contract. Contracts with minors are examples of avoidable contracts. o Unenforceable: If a contract is unenforceable, neither party may enforce the other's obligations. For example, in the United States, a contract is unenforceable if it violates the Statute of frauds . An example of the above is an oral contract for the sale of a motorcycle for US$ 5,000 (because in the USA any contract for the sale of goods over US$500 must be in writing to be enforceable).
