Case Highlights

Fighting for a child's legacy, and making new law. When a child's biological father died, the decedent's parents claimed to be the only heirs because the child had been adopted by his mother's husband. Kathi represented the child in an appeal, resulting in the published decision Matter of Estate of Ryan, 187 Ariz. 311, 928 P.2d 735 (App. 1996), and the determination that the adopted child retained inheritance rights from both biological parents.

Winning Supreme Court backing. The Arizona Supreme Court adopted Kathi's position in a brief she'd written on behalf of her client, in an amicus brief filed in an appeal. In Mid Kansas Federal Sav. and Loan Ass'n of Wichita v. Dynamic Development Corp., 167 Ariz. 122, 804 P.2d 1310 (1991), the court found that the principles of merger and extinguishment did not apply and did not preclude a construction lender, which had acquired title to property at trustee's sale, from bringing a deficiency action against a developer for the balance due on a note.

Defining and Analyzing Complex Community Property Law. A creditor garnished a couples' community property bank account to satisfy an out-of-state judgment against the husband, based upon a personal guaranty signed only by the husband. Kathi represented the couple on appeal, resulting in the published decision Rackmaster v. Maderia, 193 P.3d 314 (App. 2008). The Court concluded that Arizona law bars collection of the guaranteed debt from the community's property, and protects the rights of a spouse who has not signed a personal guaranty.
