statute], affirmed, 354 U.S. 416 [77 S.Ct. 1360, 1 L.Ed.2d 1456]; Armstrong v. Armstrong, 162 Ohio St. 406, 410-411 [123 N.E.2d 267], affirmed, 350 U.S. 568 [76 S.Ct. 629, 100 L.Ed. *705]; Spradling v. Spradling, 74 Okla. 276, 277-279 [181 P. 148]; Wilford v. Wilford, 38 R.I. 55, 56-58 [94 A. 685] [contested divorce]; Nelson v. Nelson, 71 S.D. 342, 345-346 [24 N.W.2d 327]; Toncray v. Toncray, 123 Tenn. 476, 491-492 [131 S.W. 977, Ann.Cas. 1912C 284, 34 L.R.A.N.S. 1106]; Hutton v. Dodge, 58 Utah 228, 237 [198 P. 165] ; Hicks v. Hicks, 69 Wash. 627, 630-631 [125 P. 945]; Ische v. Ische, 252 Wis. 250, 260-263 [31 N.W.2d 607, 32 N.W.2d 70].) Several of these cases rest upon familiar theories of jurisdiction : either that the divorce court had not decided the issue of alimony (e.g., Ische v. Ische, supra, at 260-263; Hicks v. Hicks, supra, at 630; Malcom v. Malcom, supra, at 726), or that the divorce court, having no jurisdiction over the wife, could not cut off her right to alimony (e.g., Armstrong v. Armstrong, supra, at 410). The more recent eases accept the divisible divorce theory, emphasizing the dominant concern of the wife’s domiciliary state in protecting her right to support from a husband who seeks to avoid his duties by obtaining an ex parte divorce in a foreign state (e.g., White v. White, supra, at 307-310; Hopson v. Hopson, supra, at 844; Pawley v. Pawley, supra, at 472; Willoughby v. Willoughby, supra, at 66-67; Davis v. Davis, Ky., supra, at 257; Vanderbilt v. Vanderbilt, supra, at 350-351; see also Morris, Divisible Divorce,* 64 Harv.LRev. 1287).
Although this precise question has not been settled in this state, certain rules have been established in related cases. We have held that an Ulinios wife could enforce an Illinois support order entered subsequent to her husband’s ex parte Nevada divorce (Lewis v. Lewis, 49 Cal.2d 389, 394 [317 P.2d 987].) Although we invoked the Vanderbilt holding in the Lewis case, we there applied Illinois law and were not called upon to determine the force of the Vanderbilt case upon our own law. Similarly, in Worthley v. Worthley, 44 Cal.2d 465 [283 P.2d 19], we held that a New Jersey wife could enforce a New Jersey separate maintenance decree entered before the husband’s ex parte Nevada divorce. Again, New Jersey law provided the rule of decision and we followed the Supreme Court’s similar holding in the Estin case. The Estin rule was applied under California law in a ease holding that an ex parte Nevada decree did not terminate a wife’s right to receive permanent alimony awarded in a prior California interloeu
