Luis and Maria Rojas contracted to buy a house in Westchester County, New York, from Andrew and Karen Paine. The house was on property designated as “Lot No. 8” on a subdivision map filed in the county clerk’s office. The Paines had acquired the property in two parts by the transfer of two separate deeds. At the closing, they delivered a deed stating that it covered “the same property.” In fact, however, the legal description attached to the deed covered only the portion of Lot No. 8 described in one of the two previous deeds. Attorney Paul Herrick represented the Rojases in the deal with the Paines. When the Rojases sought to sell the property two years later, the title search revealed that they owned only part of Lot No. 8, and the buyer refused to go through with the sale. Is Herrick liable for malpractice? Explain.
