    • Author, "Should Equitable Indemnity Apply Against Negligent Misrepresentation Claims?" The Daily Journal 2010.  Summary:  "The law is clear that a party is entitled to seek equitable indemnity against negligence claims alleged against it. Similarly, the law is clear that a party is not entitled to indemnity against fraud, intentional torts and other torts for which the application of indemnity would violate public policy. But the law is much less clear as to a party’s right to indemnity for negligent misrepresentation, a cause of action which straddles the line between negligence and fraud.

The deposit is one way the buyer can communicate to the seller that he or she really means business. Indeed, such deposits have for years been commonplace. Recently, however, the court of appeal ruled that a non-refundable deposit is in reality a form of liquidated damages and voided the practice despite the clear contractual documents that called for it. (Kuish v. Smith, 181 Cal.App.4th 1419 (2010).) Whether the Kuish decision is a good thing or a bad thing is not the point; the fact is, real estate lawyers and their clients must deal with a new reality when proceeding to escrow...", 2010
