HamiltoN, Judge,
delivered tbe following opinion:
Tbe questions raised by tbis suit relate to tbe jurisdiction of tbis court in connection witb tbe inberitanee and title quieting (dominio) laws of Porto Rico. Tbey will be discussed as tbey bave arisen in tbe case, beginning witb those wbicb relate to tbe rights of tbe plaintiffs to sue.
1. It is argued that tbe plaintiffs bave a remedy at law in that tbe local procedure permits instruments void from fraud or other causes to be set aside, and reference is bad to Revised Statutes of United States, § 723. Tbis says that “suits in equity shall not be sustained in either of tbe courts of tbe United States in any case where a plain, adequate, and complete remedy may be bad at law.” Tbe section is declaratory of tbe usual equity rule. And that rule is subject to tbe well-known principle that where equity originally has a remedy, tbis is not taken away by legislation conferring practically tbe same remedy on a law court. Where a party to a suit in equity answers and submits to tbe jurisdiction of tbe court, as in tbe case at bar, without raising tbe question of remedy at law by some preliminary motion, it is too late for him to object on the merits that such a remedy exists at law. Mercelis v. Wilson, 6 Porto Rico Fed. Rep. 42 (see also 235 U. S. 579, 59 L. ed. 370, 35 Sup. Ct. Rep. 150); Kilbourn v. Sunderland, 130 U. S. 505, 514, 32 L. ed. 1005, 1008, 9 Sup. Ct. Rep. 594.
Moreover, it would seem that tbe equitable remedy to remove a cloud from tbe title has been enlarged by tbe local law so as to obviate tbe necessity for tbe plaintiff to be in possession when be sues. Tbe Porto Rico Code of Civil Procedure, § 282, declares that “an action may be brought by any person against [541]*541another who claims an estate or interest in real property adverse to bim for the purpose of determining such adverse claim.” “This is taken from § 738 of the California Code of Civil Procedure, which has been construed as applicable to plaintiffs out of possession. More v. Steinbach, 127 U. S. 70, 32 L. ed. 51, 8 Sup. Ct. Rep. 1067. In a case very similar to the one at bar, Parés v. J. Peynes & Co. 2 Porto Rico Fed. Rep. 402, 422, it was declared that the remedy at law was not plain, as the complainant would have first to go into court and set aside the proceeding, — in that case an expediente pos-esorio, — and later bring another suit to set aside a deed in question, then bring a proceeding against heirs to supply a lost deed, and still another to have his final title registered. The result, therefore, is not only that there is not an adequate remedy at law under Pevised Statutes, § 723, but this court has jurisdiction in equity in order to prevent a multiplicity of suits growing out of the alleged cloud upon plaintiff’s title.
2. The point is made by the defendants that the plaintiffs have brought in the local district court at Humacao a suit against defendant José Alvarez y Gonzalez to reivindicate the land in question, and it is alleged that as this action is still pending, it constitutes a conflicting lis pendens. The claim is that this court of equity has, therefore, no jurisdiction to proceed with another suit as to the same issue. This contention, however, seems to be without merit. The local suit in question was against Alvarez as owner, and subsequent to its institution there were had the dominio proceedings now sought to be set aside. If these proceedings stand, the local suit of reivindicación cannot proceed. The very object of the present suit is to set aside the dominio proceedings which stand in [542]*542the way of the reivindicación proceedings for tbe land itself. Whether it will be necessary -ultimately to dismiss the local reivindicación proceedings or not, in order that all questions may be settled in the suit in this court, is a matter not before us. The suit at bar could at least proceed so far as relates to the attack upon the dominio proceedings.
3. It is argued, however, that plaintiffs have no standing in court, because they have not been adjudicated to be the heirs of Aquilina Salcedo, who is shown to have died October 3, 1883. It is unquestionably true that the local law requires certain special proceedings for the declaration of the heirs of a-decedent. This is called a “declaratoria de herederos,” and is provided in the law for special proceedings as to decedents, approved March 9, 1905, as follows:
“Sec. 19. In eases of intestate succession, or of the nullity of a will, those who may have an interest in the inheritance may petition the district court of the last domicil of the decedent, or of the place where his property is situated, for the issuance of the corresponding order of heir’s declaration.
“(1) The petition shall state, under oath, the death of the person the heirship or succession to whom is claimed;
“(2) That according to the best information and belief of the petitioner, who shall state the sources of such information and the grounds for such belief, the said decedent died without leaving a will; that due search and inquiry have been made and that none has been found, or if he left a will, that same has been declared void;
“(3) The names and domicils of persons who are entitled to the heirship or succession; or
“(4) The probatory means of which the petitioner intends [543]*543to make use in order to prove that those indicated by him are the only heirs.
“The judge to whom the petition has been presented, in the briefest period possible, shall hear the proof presented, and from the result thereof shall issue the proper order. Said order shall be issued without prejudice to a third party, unless it relate to heirs at law.” [Rev. Stats. & Codes 1911, p. 302].
There would seem to be no question that this procedure must be followed where it is a matter of general succession. The point involved here, however, is whether such a proceeding is a prerequisite to suit for a particular piece of land? There is no question that the Federal court is not a court of probate, and would not in general be the form in which such a special procedure would be taken. It is a very different proposition, however, that the Federal court must sit idle until such a procedure has been had in a local court in regard to a particular piece of land. Such, certainly, was not the law prior to the act of 1905.
The present plaintiffs are not proceeding as the heirs of Aquilina Salcedo. She died in 1883, leaving two brothers. Both brothers subsequently died, and the plaintiffs claim as the representatives of the one leaving issue. Is it necessary that these.two brothers, who died long before 1905, be declared the heirs of Aquilina? The Civil Code of Porto Rico, which copies the Civil Code of Spain in force at the time of the death of the surviving brother in 1892, declares that the right which the relatives of a person have to succeed him, called the right of representation, applies in the direct descending line, and in the collateral is also effective in favor of the children of brothers and sisters. Civil Code, §§ 898, 899. These broth[544]*544ers were, therefore, proper representatives of Aquilina at tbe time of her death, and so far as is shown there was no law at that time requiring any special proceedings to have them declared such.
Moreover, it has been held that a local district court can find plaintiffs to be such representatives ad hoc without any evidence of special proceedings to declare them heirs. Morales v. Landrau, 15 P. R. R. 761, 777. The ingenious argument is suggested that if a court cannot make a general declaration of heirship, it cannot make a special finding thereof in regard to a particular piece of property. But this does not follow. Indeed, in Soriano v. Rexach, Sup. Ct. P. R., March 9, 1916, the reivindicación proceeding is ranked more satisfactory. All land in a state has an owner, and while the state may make laws as to probate proceedings, and these should be followed in all proper cases, it still remains that if such proceedings have not been had, nevertheless each individual piece of land must be owned, and such owner must be in the position of suing or being sued in regard thereto. This is a distinct proposition from the universality known as a succession, wherein a dead man is kept alive, so to speak, in his heirs for payment of debts and other purposes. The power of a court.of general jurisdiction to proceed in a suit for property without waiting for the special proceedings under the law of 1905 is fully recognized both in Porto Bico and in Spain. Velilla v. Piza, 17 P. R. R. 1069; Collado v. Perez, 19 P. R. R. 881. To the same effect was the holding of this Federal court in Santiago y Muñiz v. Amangual, ante, 111. This court has no general probate jurisdiction, and none under the special proceedings of 1905; but the Federal courts of chancery have the right [545]*545to exercise original jurisdiction, the proper diversity of citizenship existing’, in favor of heirs to establish their claims. If a bill seeks more than this court can grant, the decree will, nevertheless, go to the extent that the court has jurisdiction. Waterman v. Canal-Louisiana Bank & T. Co. 215 U. S. 33, 43, 54 L. ed. 80, 84, 30 Sup. Ct. Rep. 10.
Bor completeness it may be added that there is no question one of several heirs cannot, until the completion of the special proceedings in Porto Pico for liquidation, claim any particular piece of property, because he has only an inchoate fractional interest. Fernandez v. Velazquez, 17 P. R. R. 116; Trinidad v. Trinidad, 19 P. R. R. 616. This principle is not applicable to the case at bar, a suit by all representatives to have removed a cloud on their title.
This is a suit to establish rights of plaintiffs in direct succession to Manuel de Jesus Salcedo, who died in 1892, being at the time the only representative of Aquilina. The plaintiffs have been duly declared heirs of Manuel by a decree of January 11, 1916, in the special proceedings provided for by law. The bill, therefore, is not subject to the objection that it is a suit brought by remote collaterals.
4. It is further claimed that the plaintiffs have no right to the property late of Aquilina, because she left a will making other disposition of it. This will is alleged to have been made April 12, 1883, as a joint will with her husband, the defendant Alvarez. Such a will is not now legal under the Civil Code, § 677. The instrument was not signed, sealed, or rubricated by the notary, Eugenio de Torres, before whom it was executed. It was not offered at the trial as part of the chain of title, but for the purpose of showing that the plaintiffs [546]*546are not beirs until the will is set aside. In this paper defendant José Alvarez y Gonzalez and Aquilina Salcedo y Rodriguez de Alvarez “authorize the present nuncupative will to the effect that upon the death of either one the other succeeds to all their property, and wish this original deed kept in the general current archives.” There it has remained ever since, and no one has sought to probate or record it in Spanish times, or under the American domination. Act March 9, 1905, §§ 9, 18, 65.
It has now been thirty-three years since the alleged will was executed. Under the Civil Code effective here since 1889, § 113, “wills executed without the authentication of a notary shall be void if they are not afterwards reduced to a public instrument and placed in the protocol.” Under the act of 1905 relating to special legal proceedings, § 1, a nuncupative will may be reduced to a public instrument on the application of a beneficiary, one upon whom a duty is imposed by the will, a legal representative of either of these two, or a witness to the will, and substantially the same requirements existed under the old Spanish law. Thirty, or perhaps twenty, years furnish a limitation to the right to probate a will. Civil Code, §§ 1860, 1864, etc. In equity at least, such an instrument, void on its face under the local, law, will be a stale demand after twenty years. Whatever might have been the rule as to the above proceedings in the local courts in past years, if the paper could not be enforced, it cannot now in this court be set up for any purpose. Under § 665 of the Civil Code, “the rights to the succession of a person are transmitted from the moment of his death.” Under § 666, “succession is granted either by the will of a man as expressed in a will, or in its absence by provision of law. The first is called testamentary, the second [547]*547legal succession.”. Under § 669, “heirs succeed the deceased in all his rights and obligations by the mere fact of his death.” It follows, therefore, that in this case there was no valid will on the part of Aquilina.
5. The point is raised that all question of heirship or representation on the part of the plaintiffs is already foreclosed by previous court decisions, that it is, in fact, res judicata. This principle is, of course, one which is well known. The definition of Lord Hardwicke in Gregory v. Molesworth, 3 Atk. 626, has been approved by many authorities. This was that when a question is necessarily decided in effect, though not in express terms, between parties to the suit, they cannot raise -the same question as between themselves in any other suit in any other form. Res judicata is not the same as estoppel. Estoppel rests on equitable principles, and res judicata rests on maxims which are taken from the Soman law. It is a fundamental concept in the organization of civil society. Bouvier’s Law Dict. s. v. According to Lord Blackburn, the doctrine was not received in England directly from the Roman law, as it was on the Continent, but nevertheless it is an integral part of the laws as administered in the English and American courts. It is equally well recognized in Porto Rico. To be effective there must be a final determination of the cause on the merits. It requires a concurrence of three or four conditions, as follows: (1) identity in the thing sued for; (2) identity of the cause of action; (3) identity of persons and of parties, including the quality in which they sue. The fundamental principle of the rule, is that the decision of a court of competent jurisdiction is a final settlement of the questions involved in any particular controversy as to the parties concerned therein, and as to any title claimed under those parties. [548]*548Wells, Res Adjudieata, § 5; Vega v. Rodriguez, 21 P. R. R. 318. There must be an identity of things, causes, and parties.
The particular judgments set up in this case as res judicatw are that of the court of first instance at Humacao, debarring her two brothers from being declared the heirs of Aquilina, and that of 1914, debarring these plaintiffs in the same way. Ordinarily in probate matters in the United States, the decree of a court is in rem, conclusive against the world. Such a decree is a declaration of status, and the civil law is especially rich in all matters affecting status. It is not necessary to determine whether the heirship proceedings under the old Spanish procedure had this nature in all respects. The proceeding of 1883 does not pretend to decide the question of heirship. The court determined that, as it was an indispensable condition that there should be in existence no testamentary disposition, and as there was shown to exist a paper purporting to be a will, which nevertheless the court was not called upon to pass upon, the petition was denied. In other words, the case was not decided on the merits, whether it was in rem or m personam.
The same is true of the proceeding in 1913 to have the present plaintiffs declared heirs ab intestato of Aquilina Sal-cedo. The defendant Alvarez appeared as a party, and by evidence of the existence of the alleged will, not declared void by any competent court, succeeded in having the Humacao district court deny the petition “until the petitioners justified their right before some competent court.” This was not a decree upon the merits, because it denied the petition only until petitioners justified their right. This they are now doing, and so far as relates to the obstacle to the action of the Humacao [549]*549court, the supposititious will, that was eliminated by time, as seen above.
There is therefore no question of res judicata, in the case as it comes before this court.
6. It is maintained, however, on behalf of the defendants, that Aquilina during her lifetime had already sold the property to defendant Concepción Andreu, and that Concepcion’s dominio proceedings in the district court of Humacao March 4, 1915, validly established the title in her, after which she sold to the defendants trustees of the Fajardo Sugar Growers Association. The question, therefore, now comes up as to this dominio proceeding. Under article 395 of the Mortgage Law, modified in part by the military order of April 4, 1899, proceedings to establish title may be as follows:
“Art. 395. Any owner of property having no written title of ownership whatever be the period of the acquisition, may record such ownership upon proving it under the following formalities:
“1. He shall submit to the judge of the court of first instance of the judicial district in which the property is situated, or to the one of the district in which the larger portion thereof is situated, if the estate be located in more than one district, a statement of the manner in which he acquired it and any legal proof of such acquisition which he may have to offer, and praying that, after citation of the person from whom the property may have been acquired, or of his predecessor in interest, and of the representative of the department of public prosecution, such evidence be admitted and a declaration of his rights made.
“2. The judge shall refer this petition to the representative [550]*550of the department of public prosecution, shall cite the person from whom the property was acquired or his predecessor in interest, if known, and the persons who may have any property right in said real property; he shall admit all pertinent evidence which may be offered by the petitioner, by the interested persons cited or by the representative of the department of public prosecution within the term of 180 days, and he shall summon the unknown persons who might be prejudiced by the record applied for, by means of notices which shall be posted in public places and inserted three times in the official newspapers of the respective colonial province, in order that they may appear if they wish to assert their rights.
“If the persons to be cited should be absent, the procedure established in rule 5 of article 391 shall be followed in making the citations.
“3. Upon the expiration of this period, the judge will receive written pleadings upon the claims and evidence which may have been presented by the representative of the department of public prosecution or by the other persons who may have attended the proceedings; and in view of their allegations he shall decide on the evidence with an impartial judgment and declare whether or not the ownership of the property involved has been established.
“4. The representative of the department of public prosecution or any of the persons interested may appeal from this decision; and should they do so, the appeal shall be heard and decided according to the procedure established for incidental issues in the law of civil procedure.
“5. If said decision is accepted or affirmed, it shall constitute a sufficient title for the record of the ownership.
[551]*551“6. When, tbe value of tbe real property shall not exceed 1,000 pesos, tbe proceedings wbicb, according to rule 3, must be bad in writing and submitted to tbe representative of tbe department of public prosecution and to tbe parties interested, shall be oral; and tbe appeal, in a proper case, shall conform to tbe procedure established for appeals of this character in actions of ‘lesser import’ .(menor cuantia).”
In tbe case at bar these proceedings were bad, resulting in a decree of tbe district court of Humacao, March 4, 1915, wbicb was registered in tbe registry of property at Humacao, the finca being described as “119 acres of land. Vol. 16 Naguabo; Folio 33, Finca 468, Second inscription.” This proceeding is now alleged to have been fraudulent, and tbe removal of it' as a cloud is tbe main issue in tbe case at bar.
It is shown by tbe evidence in this case, and indeed by tbe evidence in tbe dominio proceeding, that Alvarez was at tbe time of tbe alleged sale tbe husband of Aquilina, and that after tbe death of Aquilina, tbe vendor, be became tbe husband of Concepción, tbe vendee.
Tbe Mortgage Law above requires that in dominio proceedings tbe person from whom tbe property was acquired, or bis legal representatives, should be cited. In tbe proceeding in question tbe notice was issued to Alvarez, tbe husband of both tbe grantor and tbe grantee. Tbe only theory upon which this could be justified was that be was tbe heir of Aquilina under tbe will above discussed. This will, however, has never been established as a will, and whatever might be its negative power as to other proceedings at that time, certainly it has no positive power of conferring title. Ex parte Perrier, 20 P. R. R. 119. It follows, therefore, that tbe notice was not is[552]*552sued to tbe proper representatives of tbe succession of Aquilina Salcedo. Alvarez, moreover, was tbe chief witness for tbe petitioner in tbe dominio proceedings.
Tbe petition is also improper in that it recites there was no inscribable. title to tbe property. It may be questioned whether a dominio proceeding was proper in this case in any event. Tbe defect of Concepción, if she owned tbe property, was not in there being no inscribable title to tbe property, but in her having never received a deed from Aquilina. In such case tbe proper procedure would have been, not dominio proceedings, but one to establish tbe title, somewhat as in tbe case at bar.
If tbe proceeding were regular, this court would not go behind tbe face of tbe record. It being, however, open to tbe objection of tbe plaintiffs in this case, it is to be noted that tbe evidence offered for Concepcion’s purchase from Aquilina is not at all satisfactory. Tbe principal testimony is that of her husband, tbe defendant Alvarez, whose statement is vague at best. He says, “We were taken sick and there was that lady widow there, and we ran to her, and she being our neighbor, and we sold that property to her.” Tbe lady widow in question was Concepción, and tbe testimony leaves it quite doubtful that Aquilina was in any such need. At her death shortly afterwards she bad other property, and tbe possession of tbe land in question never apparently changed bands. Alvarez married Aquilina, February 8, 1883. On April 12 of tbe same year they attempted to make a joint will, and at that time bad no debts. Tbe sale to Concepción must have been about August, as it was several months before tbe death of Aquilina¿ October 3, 1883. There is no evidence that Con-[553]*553cepción bad any sucb sum as 1,500 pesos to pay for tbe finca, and improbable that she would do so if she had it without obtaining a deed, particularly as less than a year before she had exacted a public deed for another piece of property she bought. Aquilina was assessed with this property for the succeeding tax year, and thereafter it seems to be assessed to Alvarez for several years. It is true that the description of these assessments is vague, but it seems to be shown that he was never in possession of any other property than the finca in question. The secrecy of all these circumstances is not unlike those in the Gaines Case, 6 Wall. 642, 18 L. ed. 950. All the evidence in the case tends to show that the claim of ownership was made by defendant Alvarez for many years, and that a claim by Concepción was not known. Plaintiff’s attack, therefore, upon the validity of the dominio proceedings seems to be justified.
No independent right is set up by the defendant trustees of the Fajardo Sugar Growers Association under the purchase of March 10, 1915. Their deed is not in evidence, and so no question arises under the mortgage or registration laws of Porto Eico, and there are no allegations or proof tending to establish any rights on their part as bona fide purchasers for value without notice, an equitable doctrine which is a rule of inaction by the court rather 'than a rule of property. 2 Pom. Eq. Juf. §143. As presented, this case relates to the legal title, the power of this court to remove clouds from titles by canceling conflicting instruments or proceedings. The Fajardo claim seems to stand or fall with that of Concepción, the grantor.
It only remains to say that the rulings of the court made pro forma during the trial will be considered as final upon [554]*554the points involved, and that the facts recited in this opinion and preceding statement are those found by the court for the purposes of the case.
It follows, therefore, that the bill has been made out, and that a decree should be entered for the plaintiffs.
It is so ordered.
