*396OPINION OF THE COURT
Mahoney, J.In 1985, plaintiff commenced what ultimately turned out to be an unsuccessful action for divorce against defendant, his wife of 25 years, in Supreme Court, Broome County. A temporary order of support for defendant was issued, however, as the parties were living separate and apart. Four years later plaintiff relocated to Pennsylvania and brought another action for divorce, this time in the Pennsylvania Court of Common Pleas. Defendant appeared and defended. Ultimately, a divorce decree was issued and equitable distribution of the parties’ marital property was effected. The Pennsylvania court, however, made no maintenance award. Rather, it expressly noted that "a New York court has already entered a maintenance order” and referred the parties to the New York courts for resolution of this issue.
Several months after rendition of the Pennsylvania divorce decree, defendant applied to Supreme Court, Broome County, for a modification of the prior support order. While the court initially granted the modification request, upon reapplication by plaintiff it revoked its prior determination and terminated defendant’s support in its entirety on the ground that this "issue has been raised and decided by the * * * [Pennsylvania] Court of Common Pleas”. Defendant appeals.
Initially, we note that to the extent Supreme Court grounded its termination of the support order upon the theory that the Pennsylvania judgment collaterally estopped defendant from relitigating this issue, such was error. It is clear from a reading of the Pennsylvania court’s decision that the maintenance issue was neither litigated nor determined in that proceeding (see, e.g., Nikrooz v Nikrooz, 167 AD2d 334, 335; Mahoney v Mahoney, 131 AD2d 822, 823; Braunstein v Braunstein, 114 AD2d 46, 52-53, lv dismissed sub nom. Sorman-Braunstein v Braunstein, 68 NY2d 753).
This is not the end of the inquiry, however. Because the obligation of spousal support ordinarily exists only during marriage and terminates upon divorce, and because the support order sought to be modified here was entered prior to entry of the Pennsylvania divorce, resolution of the ultimate issue presented requires us first to determine whether the support order survived the Pennsylvania divorce. As we recently explained, because the divorce decree was issued from a foreign jurisdiction, resolution of this query necessitates exam*397ination of the law of the State issuing the divorce (Frankel v Frankel, 158 AD2d 750, 752). If under that State’s law a prior temporary support obligation is deemed to be extinguished upon the subsequent entry of a divorce decree, under principles of comity the New York courts likewise will extinguish previously entered New York support orders (see, supra). Research into Pennsylvania law on this subject reveals it to be well established that a jurisdictionally valid bilateral domestic or foreign divorce decree does indeed terminate the spousal duty of support and necessitates vacatur of any prior support orders (see, Watson v Watson, 243 Pa Super 23, 28, 364 A2d 431, 433; Commonwealth ex rel. Lorusso v Lorusso, 189 Pa Super 403, 406, 150 A2d 370, 372; see also, Stinner v Stinner, 362 Pa Super 219, 523 A2d 1161, revd on other grounds 520 Pa 374, 554 A2d 45). While less clear, this proposition appears to apply regardless of whether the divorce court actually disposed of the issue of spousal maintenance, either by granting it or expressly denying it (see, Watson v Watson, supra; Commonwealth ex rel. Lorusso v Lorusso, supra). Application of the above principles to this case results in the conclusion that the New York support order at issue here has been extinguished. Accordingly, while we disagree with the apparent rationale underlying Supreme Court’s determination, we agree that vacatur of the support order is warranted in this case.*
This conclusion does not leave defendant without a remedy, however. Inasmuch as the issue of maintenance was not addressed or resolved in the Pennsylvania divorce action, there is no bar to defendant now litigating that issue in New York in the posture of a proceeding pursuant to Domestic Relations Law § 236 (B) (2) for maintenance following a foreign judgment of divorce (cf., Braunstein v Braunstein, 114 AD2d 46, supra).
