[1] General Statute No. 8-50.1 provides that, “[i]n the trial of any civil action, the court before whom the matter may be brought, upon motion of either party, shall direct and order that the defendant, the plaintiff, the mother and the child shall submit to a blood-grouping test; provided. . . .” In Wright v. Wright, 281 N.C. 159, 188 S.E. 2d 317 (1972), the court held that this portion of the statute, applicable to civil actions only, is qualified by certain language found in that portion of the statute dealing separately with criminal proceedings. The portion of the statute dealing with criminal proceedings provides, “[i]n the trial of any criminal action or proceedings . . . in which the question of paternity arises, . . . the court before whom the matter may be brought, . . . shall direct and order that the defendant, the mother and the child shall submit to a blood-grouping test; provided. . . .” That the italicized portion of the criminal proceedings section of the statute applies as well to the civil proceedings section of the statute was the holding in Wright. Thus, before a court is required to order a blood-grouping test in a civil action, the question of paternity must arise. If defendant in this case is barred by res judicata or estoppel from raising the issue of paternity as plaintiff contends, the statutorily imposed obligation of the court to order that the parties submit to blood-grouping tests never arose, and it was error for the court to enter such order.
*144 [2] The parties bring to our attention two cases that have considered the initial question of whether the issue of paternity can be raised by a party to a civil action. In Wright, supra, an action brought by the wife for custody and support of the parties’ minor children, the husband filed an answer admitting a particular child was born of the parties’ marriage and that he owed a duty of support to the child. Subsequently, however, the husband made a motion for a blood-grouping test, which the court granted. When the results of the tests indicated the husband was excluded as the father of the child, the court granted the husband’s motion to amend his answer by deleting his admissions of paternity. On appeal the wife contended on the basis of the husband’s admissions in his original answer and his previous conduct acknowledging paternity of the child that he should be estopped from raising the issue of paternity. Although acknowledging that “[i]t may be that the putative father of a child conceived or born during wedlock should be estopped to raise the issue of paternity unless he does so within a fixed time,” the court rejected the wife’s contention on grounds that such a result must be effected by legislative action. Id. at 172, 188 S.E. 2d at 326.
Brondum v. Cox, 30 N.C. App. 35, 226 S.E. 2d 193 (1976), affirmed, 292 N.C. 192, 232 S.E. 2d 687 (1977), presented substantially the same issue raised in this appeal. In that case, plaintiff-wife brought an action under the Uniform Reciprocal Enforcement of Support Act to obtain an order requiring her ex-husband to support her child. Plaintiff-wife’s action was based on the provisions of a Hawaiian divorce decree obtained by her in a proceeding in which her ex-husband made no appearance, although the Hawaii court attempted to exercise personal jurisdiction over him by serving the summons, complaint, and other papers on him by mail in North Carolina, where he was domiciled at the time. Defendant-husband filed an answer to plaintiff-wife’s enforcement action denying he was the father of the child and requesting an order for a blood-grouping test. The District Court entered an order finding the Hawaii court had only in rem jurisdiction to enter the divorce, child custody, and child support decrees. The court ruled, however, that because the issue of paternity was inextricably bound up in the determination of the above matters, the finding of paternity by the Hawaii court was conclusive and the issue could not be relitigated by defendant-husband in *145plaintiff-wife’s enforcement action. From the denial of his motion, defendant-husband appealed to the Court of Appeals, which reversed the judgment of the District Court in an opinion subsequently affirmed by the Supreme Court. The reversal by the appellate court was based on the conclusion that a judgment establishing the status of paternity is one in personam and can be rendered only by a court having jurisdiction over the person of the defendant, which the Hawaii court did not have in plaintiff - wife’s divorce action. Therefore, the courts of North Carolina were not required to accord full faith and credit to that part of the Hawaiian judgment finding defendant-husband to be the father of plaintiff-wife’s child, and defendant-husband was entitled to raise the issue of paternity in plaintiff-wife’s enforcement action.
We think the court’s holding in Wright applies only to the estoppel contentions raised by plaintiff. The factual basis of plaintiff’s contention that defendant should be estopped from denying paternity because of a past history of both formal and informal acknowledgment of paternity of the child is substantially the same as that shown in Wright. We agree with the Supreme Court’s suggestion that, “. . . the putative father of a child conceived or born during wedlock should [perhaps] be estopped to raise the issue of paternity unless he does so within a fixed time.” But we also realize that “. . . is a matter for consideration by the General Assembly.” Wright, supra, at 172, 188 S.E. 2d at 326.
Brondum, however, is distinguishable from the case under consideration and offers considerable support, albeit in dictum, for the disposition we make of this case. The critical, underlying basis for the court’s decision in Brondum that the adjudication of paternity in the wife’s Hawaiian divorce action was not entitled to full faith and credit in the courts of this state was the fact that the Hawaiian court did not have in personam jurisdiction over defendant-husband when it granted plaintiff-wife a divorce and adjudicated the issue of paternity. See Survey of Developments in North Carolina Law, 1977, Civil Procedure, 56 N.C.L. Rev. 874-76 (1978). In this instance, the Nevada court, which granted plaintiff a divorce, awarded her child custody and support, and decreed the child, Joelle, to be a child born of the marriage, did have jurisdiction over the person of defendant. Among the documents relating to the Nevada proceeding that plaintiff sub*146mitted to the District Court was a power of attorney properly executed by defendant authorizing a Nevada attorney or his designate to “enter my appearance and represent me in said action at any time after the Complaint is filed to the same extent as if I were personally present. . . The record further shows that the attorney so authorized filed an answer on defendant’s behalf in which it was admitted that the child, Joelle, was born the issue of the marriage.
“While it is true that no consent can give a court jurisdiction of the subject matter of an action which the court does not possess without such consent, it is equally true that a court may obtain jurisdiction over the person of a party litigant by his consent.” Jones v. Brinson, 238 N.C. 506, 509, 78 S.E. 2d 334, 337 (1953). It is also uniformly held that a general appearance by a defendant in a civil suit is sufficient to confer jurisdiction over his person on the court before which he appears. In re Blalock, 233 N.C. 493, 64 S.E. 2d 848 (1951). And a defendant may appear either himself or he may authorize another to appear for him. 5 Am. Jur. 2d, Appearance, § 10, p. 487. In view of the fact that defendant properly authorized an attorney to enter a general appearance for him in the Nevada divorce proceeding and the attorney so authorized filed an answer to plaintiff’s complaint in that action, it is clear that the Nevada court had jurisdiction over the person of defendant. Defendant is therefore bound by any order of the Nevada court requiring the assertion of in personam jurisdiction.
“The constitutional command of full faith and credit, as implemented by Congress, requires that ‘judicial proceedings . . . shall have the same full faith and credit in every court within the United States ... as they have by law or usage in the courts of such State . . . from which they are taken.’ Full faith and credit thus generally requires every State to give to a judgment at least the res judicata effect which the judgment would be accorded in the State which rendered it.” Durfee v. Duke, 375 U.S. 106, 109, 84 S.Ct. 242, 244, 11 L.Ed. 2d 186, 190 (1963). And in Sears v. Sears, 253 N.C. 415, 417, 117 S.E. 2d 7, 9 (1960) our Court noted, “[t]he rule in North Carolina is that a divorce decree rendered in a sister state which is valid and entitled to recognition under the Full Faith and Credit Clause of the United States Constitution, Art. IV, Sec. 1, is res judicata as to all matters in issue and deter*147mined, and a bar to a subsequent suit for the same relief.” See also Garner v. Garner, 268 N.C. 664, 151 S.E. 2d 553 (1966); Laughridge v. Lovejoy, 234 N.C. 663, 68 S.E. 2d 403 (1951); 3 Nelson, Divorce and Annulment, § 33.39, pp. 508-9, (2d ed. 1945); Wurfel, Recognition of Foreign Judgments, 50 N.C.L. Rev. 21 (1971).
We have not found a decision of the Nevada courts on the question of the res judicata effect of a determination of paternity in a divorce action. We are confident, however, that our application of the principles of res judicata to this case meets the constitutional requirement that the courts of this state accord to the judgment of a sister state at least the res judicata effect which the judgment would be accorded in the sister state rendering it. See Durfee v. Duke, supra.
That a judgment rendered by a court having jurisdiction to do so finding paternity to exist bars the relitigation of that issue by the parties to the original judgment is a well established rule of law in other jurisdictions that have considered the question. Adoption of Stroope, 232 Cal. App. 2d 581, 43 Cal. Rptr. 40 (1965); Peck v. Superior Court, 185 Cal. App. 2d 573, 8 Cal. Rptr. 561 (1960); Peercy v. Peercy, 154 Colo. 575, 392 P. 2d 609 (1964); Sorenson v. Sorenson, 254 Ia. 817, 119 N.W. 2d 129 (1963); Dornfeld v. Dornfeld, 200 App. Div. 38, 192 N.Y.S. 497 (1922); Time v. Time, 59 Misc. 2d 912, 300 N.Y.S. 2d 924 (1969); Arnold v. Arnold, 207 Okla. 352, 249 P. 2d 734 (1952); Byrd v. Travellers Insurance Co., 275 S.W. 2d 861 (Tex. Civ. App. 1955); Johns v. Johns, 64 Wash. 2d 696, 393 P. 2d 948 (1964); E_ v. E_, 57 Wis. 2d 436, 204 N.W. 2d 503 (1973); Limberg v. Limberg, 10 Wis. 2d 63, 102 N.W. 2d 103 (1960). For a discussion of these and other cases that have considered this question, see Annot., 65 A.L.R. 2d, 1381, pp. 1395-96.
E_ v. E_, supra, is illustrative of the approach taken by most jurisdictions on this issue. In that case the wife obtained a divorce in a proceeding in which her husband appeared and admitted he was the father of her child. The court in its judgment found as a fact that the husband was the father of the child. Seven months after the judgment had been entered, the husband sought by motion to relitigate the issue of paternity. In holding that he was barred from doing so by res judicata despite the fact *148that he had not contested paternity in the divorce proceeding, the court observed:
“It is clear not only from the rulings of this court, but also from the numerous other jurisdictions which have considered the question, that the issue of the paternity of minor children becomes res judicata between the parties under the original divorce decree, and that it is error for a trial court to subsequently either vacate or modify the original judgment on the grounds that one of the alleged parents, who heretofore stood mute on the question of paternity, has now had a change of heart.” Id. at 441-42, 204 N.W. 2d at 505.
And in Peercy v. Peercy, supra, the husband and wife entered into a separation agreement, subsequently incorporated into the parties’ divorce decree, wherein the husband acknowledged paternity of the wife’s child and agreed to meet support obligations. When he later attempted to raise the issue of paternity in a contempt proceeding brought by the wife, the court held that he was barred from doing so by res judicata because the issue of paternity could have been raised, tried, and resolved in the divorce proceeding. The court also held that statutory procedures for modification of judgments did not encompass such a proposed modification.
It is a well established principle in North Carolina as well that a valid judgment is binding on the parties to it “as to all issuable matters contained in the pleadings, including all material and relevant matters within the scope of the pleadings, which the parties in the exercise of reasonable diligence, could and should have brought forward.” Bruton v. Light Co., 217 N.C. 1, 7, 6 S.E. 2d 822, 826 (1940). In Brondum, discussed supra, Justice Lake observed in dictum that the rule established in Bruton,
“. . . has been applied in other jurisdictions to determinations of paternity in divorce proceedings in which the husband and alleged father did not appear or did not contest the paternity of his child. (Citations omitted.) In our opinion this is a correct application of the rule. Thus if the Hawaii court had jurisdiction to determine the status of the child in relation to the defendant, its determination thereof would be binding upon the defendant in the courts of this State notwithstanding his failure to appear and to contest the issue of *149paternity.” Brondum, supra, at 199, 232 S.E. 2d at 691. (Emphasis added.)
The case under consideration is distinguishable from Bron-dum because the Nevada court, as we noted earlier, did have the requisite in personam jurisdiction over defendant to determine the issue of paternity. We think it presents exactly the situation adverted to by Justice Lake in Brondum, and we hold that defendant is barred by principles of res judicata from putting paternity in issue. Since defendant is barred from raising the issue of paternity in this enforcement action by plaintiff, it follows that the court below erred in allowing defendant’s motion for blood-grouping tests.
Defendant cross-assigned error to the court’s granting of plaintiff’s motion to strike the affidavit of the physician’s assistant and certain portions of defendant’s motion and accompanying affidavit. From our holding that defendant is barred from raising the issue of paternity, it follows that neither the affidavit of the physician’s assistant nor defendant’s own allegations with respect to non-access during the probable period of conception are relevant to this enforcement action brought by plaintiff. Therefore, we find no error in that portion of the court’s order granting plaintiff’s motion to strike the irrelevant matter.
That portion of the court’s order granting defendant’s request for blood-grouping tests is reversed; that portion granting plaintiff’s motion to strike is affirmed, and this cause is remanded to the District Court, Wayne County, for further appropriate proceedings.
Affirmed in part; reversed in part; and remanded.
Judges PARKER and HEDRICK concur.
