Mom owned Blackacre, a two-family apartment house on a small city lot not suitable for partition-in-kind. Upon Mom's death, her will devised Blackacre to "my sons, Joe and John." A week ago, Ken obtained a money judgment against Joe, and properly filed the judgment in the county where Blackacre is located. A statute in the jurisdiction provides: any judgment properly filed shall, for ten years from filing, be a lien on the real property then owned or subsequently acquired by any person against whom the judgment is rendered. Joe needed cash, but John did not wish to sell Blackacre. Joe commenced a partition action against John and Ken. Assume that the court properly ordered a partition by judicial sale. After the sale, Ken's judgment will be a lien on 
all of Blackacre. only a one-half interest in Blackacre. all of the proceeds of sale of Blackacre. only the portion of the proceeds of sale due Joe.
