delivered the opinion of the court.
On March 6, 1909, Jnan del Carmen Monge y Agosto, in his own right and as judicial defensor of his minor sisters, Valeriana and Mercedes, of the same surnames, filed a complaint in the District Court for the Judicial District of San Juan against Antonio, Maria, Angela, and Josefina Zechini y Veve, praying that the defendants he adjudged to return to the plaintiffs 13.68 cuerdas of land detained by them, which are the property of the plaintiffs by virtue of inheritance from their father, Juan del Carmen Monge, comprised in an estate of 27.89 cuerdas and which the defendants have recorded in their favor in the registry of property. They *731also prayed that the defendants "be adjudged to pay $1,500 as indemnity for the products of the lands detained, and the costs of the litigation.
For the purpose of securing the execution of such judgment as may he rendered with respect to the return of the 13.68 cuerdas of land, the plaintiffs also request that, so far as relates to said land, the dominion title proceedings instituted by the defendants be declared null, and that the division of the estate recorded be decreed so that delivery of their share therein may be made.
The defendants, Antonio, Angela, and Josefina Zechini y Veve, in answering the complaint on April 29 following, requested that it be dismissed in its entirety. They also filed a counterclaim against the plaintiffs praying that, should the complaint prosper, the latter be adjudged to reimburse the Succession of Zechini in the sum of $6,000, which includes the value of an estate of 50 cuerdas, and $625 spent by the defendants in acquiring, 'by exchange, the lands that the plaintiffs seek to recover, the products of said lands from 1895 to 1905, and the interest on the $625.
Later, on August 31 of the same year, they supplemented their answer by alleging that, since in 1897, they acquired the land, subject matter of this action, in good faith and by title of exchange with Cruz Agosto, and that they had already acquired dominion of said lands by prescription, in accordance with section 1858 of the Eevised Civil Code.
The trial having been held, the court rendered judgment on October 11, 1909, declaring that the plaintiffs had no right to recover from the defendants the property in litigation, and dismissed the counterclaim, which had been filed, to abide by the result of the complaint, each party to pay their own costs.
An appeal was taken from said judgment by the plaintiffs, who prayed for the reversal thereof and that another be rendered in accordance with the prayer of the complaint.
From the pleadings of the parties, combined with the *732probatory elements brought forth at the trial, the conclusions reached are:
First. That Jnan del Carmen Monge died in the town of Rio Grande on February 5, 1895.
Second. That by judicial decree of February 22, 1897, his legitimate children, Pedro and Tomás, had by his first marriage with Asunción Rivera, also his legitimate childreh, Julia Monserrate and Eulalia, had by his second marriage with Dionisia Jiménez; his natural children, Antonio Ramón, Juan Isaac, Mercedes, Esteban, and Valeriana, had by Cruz Agosto Negron; his grandchildren, Jesiis María, Esperanza, Eugenia, Enrique, and Nemesio, in representation of their deceased mother, Juana Justa Monge y Rivera; and his other two granddaughters, Lucia Candelaria and Josefa, in representation of their mother, Emilia Hernández Monge y Jiménez, were declared to be the heirs of Juan del Carmen Monge.
Third. That by deed of July 16, 1895, Rosa Cruz Agosto and Antonio Zechini Veve, the latter representing the Succession of Antonio Zechini Garcia, composed of his widow and four daughters, agreed to exchange two landed estates, one of 18.72 cuerdas situated in barrio Herrera, municipality of Rio Grande; bounded on the north by the estate “Maria” belonging to the Succession of Antonio Zechini; on the south by lands of the Succession of Juan Monge; on the east by the Espíritu Santo River; and on the west by a channel or' the former course of the Rio Grande. By private agreement with the other interested parties this property was to be adjudicated in the settlement of the estate of their father, Juan Monge, to the natural children of Rosa Cruz Agosto, to wit, Antonio, Juan, Mercedes, Esteban, and Valeriana Monge y Cruz. The other estate was the property of the Succession of Antonio Zechini y García and was composed of 50 cuerdas situated in barrio Guzmán Abajo, of the same municipality of Rio Grande; bounded on the north by lands of the Succession of Antonio Zechini; on the south and west *733by lands of the Succession of Nemesio Jiménez; and on the east by the road leading to the aforesaid barrio. The exchange was to be effected as soon as the corresponding adjudication in the settlement of the said estate was made to the children of Cruz Agosto, the parties haying by agreement valued each of the described estates at the same price.
Fourth. That on May 12, 1897, the heirs of Juan del Carmen Monge, to wit, Tomás, Pedro, and Monserrate Monge; Antonio Zechini, as assignee by right of purchase of the title and interest of Eulalia Monge; José Bloy, representing his daughters, Josefa and Lucia, had by his marriage with the deceased heir, Herminia Monge; Pelegrín Tórrales, as representative defensor of the minors, Jesús, Eugenia, Enrique, and Nemesio Sabaud, children of the deceased heir, Justa Monge; and Cruz Agosto, accompanied by her attorney in fact, Rodolfo González, in her character of mother of the minors Antonio, Juan, Mercedes, Esteban, and Valeriana Monge, proceeded to make an inventory of and to appraise, with the assistance of experts, the property left by the deceased, Juan del Carmen Monge. The total value of said property was $2,490.65, and included therein were 78.46 cuer-das of bottom land situated in barrio Herrera; bounded on the east by the Rio Grande; on the south by lands of Antonio Zechini; on the north by the covirse of the Rio Viejo and by lands of the said Antonio Zechini, equivalent to 30 hectares, 83 ares and 8 centares, at $28 a cuerda, the title of ownership of which was not produced at the trial. By agreement the heir, Pedro Monge, was appointed executor and master (contador-partidor), all of which acts were stated in an instrument signed by the interested parties in their own behalf, or by others at their request.
Fifth. That on the following day, May 13, the appointed executor and master, Pedro Monge, made the division and adjudication of the estate of Juan del Carmen Monge and reduced the facts to writing, which writing, by way of approval, was also signed by the interested parties, who renounced *734all rights in their favor, there having been adjudicated to the heir, Eulalia Monge Jiménez, 9.08 cuerdas of the above-described bottom lands, valued at $28 a cuerda, and to Antonio, Juan, Mercedes, and Esteban, children of Cruz Agosto, .4.56 cuerdas; to Valeriana there were adjudicated 4.57 Cuer-das of the-same land, no statement having been made as to the' bonndries of the portions adjudicated to Eulalia Monge and to the five children of Cruz Agosto.
Sixth. That Cruz Agosto delivered to Antonio Zechini the parcels of land adjudicated to her five children, receiving-in exchange the estate of 50 cuerdas, to which the above-mentioned deed of July 16, 1895, refers, together with $625 in cash, the agreement of exchange stated in the said deed being thus fulfilled. No judicial authorization for the contract of exchange or for the execution thereof was obtained.
Seventh. That Cruz Agosto Negrón sold the estate of 50 cuerdas, delivered to her by Antonio Zechini, to Manuel Melchor García, who paid the price thereof partly in money and partly by the transfer of a house situated in the town of Carolina. As she had not received a deed of ownership of said estate from the Succession of Zechini, it was agreed that the same should be executed in favor of Manuel Melchor García. This was done by Zechini in his own right and as attorney in fact of his sisters, Josefina, Angela, and Maria, in a public instrument of June 17, 1902, and which was recorded in the Registry of Property of San Juan. In said document the vendors acknowledged the receipt of $500 paid by the vendee as the purchase price prior to the execution of the deed.
Eighth. That with respect to the lands transferred to the defendants by virtue of the exchange with Rosa Cruz Agosto, Antonio Zechini y Veve, in his own right and as the attorney in fact of his sisters, Maria, Angela and Josefina, instituted dominion-title proceedings in the District Court of San Juan to establish his title to a rural property of 27.8936 cuerdas situated in barrio Herrera, municipality of Rio Grande, which *735property was acquired by Mm and Ms sisters four years previously by purchase from Eulalia Monge y Jiménez and Cruz Agosto. The dominion title requested was granted to the ZeehiM Yeve children on March 18, 1901, and recorded in the registry of property on June 17 of the same year.
Ninth. That Tomás Monge, Gerardo Baldrich, and An-toMo Zechini, were examined in regard to the annual production of the lands claimed by the plaintiffs. The first stated that the minimum annual rental of said lands is $8 a Cuerda, though he does not know what they produce; the second stated that if the lands were to be used for the cultivation of cane they should rent for $10 or $12 a cuerda per annum; the third stated that for the purpose of planting part to cane and part to pasture and tobacco, etc., the lands could rent, and could have rented even at the time the exchange was made, for $6, $8, or $10 a cuerda.
The facts brought out at the trial having been set forth, we are of the opinion that the judgment appealed from does not conform to law. Let us see.
The plaintiffs have title upon which to recover the 13.68 cuerdas of land which they claim as theirs.
Said title is the private document regarding the partition of the estate of Juan del Carmen Monge, in which partition four and some hundredths cuerdas of an estate of .78 and some hundredths belonging to the deceased, Monge, and situated in the municipality of Rio Grande, were adjudicated to each of the plaintiffs. ■
“A division legally made,” says section 1035 of the Revised Civil Code, which is the same as 1068 of the former Civil Code, “confers upon each heir the exclusive ownership of the property which may have been awarded to him. ’ ’ The plaintiffs, Juan del Carmen, Valeriana, and Mercedes Monge y’Agosto, therefore, acquired ownership of the lands adjudicated to them by virtue of the partition of the estate of their predecessor in interest, Juan del Carmen Monge. It cannot be alleged that the partition was illegal for lack of *736judicial approval, because section 1027 of the Revised Civil Code, which is section 1060 of the Spanish Civil Code and which was in force at the time the partition was .made, provides that “If the minors should be subject to the parental authority, and are represented in the division by the father or by the mother, in a proper case, neither judicial intervention nor approval shall be required.” Section 1048 of the former Law of Civil Procedure, which exacted such requirement in cases similar to the present, was modified by section 1060 of the former Civil Code already cited.
But even assuming that judicial intervention and approval of the partition of the estate of the deceased, Juan del Carmen Monge, was necessary, the defendant, Antonio Zechini, who intervened therein as assignee of the title and interest of the heir, Eulalia Monge, cannot plead the lack of said requirement to profit by its omission, because in accordance with section 1269 of the Revised Civil Code, which is 1032 of the former Civil Code, persons with capacity cannot plead the incapacity of those with whom they contracted, and Antonio Zechini contracted with the plaintiffs, executing' with them and with the other heirs the partition of the estate of the deceased, Juan del Carmen Monge, the former being represented by their mother.
Although the above conclusion is not applicable to the defendants, Maria, Angela, and Josefina Zechini y Yeve, as they did not intervene in the aforesaid partition, they also are prevented from attacking the same for the reason applicable to them and to their brother, Antonio Zechini, that they contracted with said minors, Zechini in his own right and they represented by Zechini, and acquired from the plaintiffs under title of exchange their corresponding shares in the partition.
The contract of exchange executed by the plaintiffs with the four defendants, wherein Zechini acted in his own right" and in representation of his sisters, is manifestly null, because section 4 of the Civil Code provides that acts performed *737contrary to the provisions of the law are void, except when the law preserves their validity, and section 164 of the Civil Code in force at the time of the acquisition of the lands, subject matter of this litigation, which is 229 of the Revised Civil Code, prescribes that neither the father nor the mother,, in a proper case, can alienate the real property of the child! the usufruct or administration of which pertained to them., or encumber the same except for justified reasons of utility or necessity and upon authorization of the judge of the district wherein they are domiciled, after hearing the fiscal thereof, excepting as the Mortgage Law provides with respect to the effects of transmission.
A similar provision is contained in section 2010 of the Law of Civil Procedure in force at the time of the exchange, and Title Y of the Law of Special Legal Proceedings, approved March 9, 1905, treats of the authority over rights and properties of minors. The law approved on March 9 of the current year contains more restrictive provisions on the same' subject.
The fact that the defendants had the order of approval made in the dominion-title proceedings, with respect to the lands acquired by them from Cruz Agosto together with those acquired from Eulalia Monge recorded in the registry of property as one estate, has no weight. Such record, according to article 33 of the Mortgage Law, cannot give validity to a contract that was void in accordance with the statutes.
Moreover, the dominion-title proceedings contained a fundamental error, by means of which it was sought in the proper court and in the registry to correct the unamendable defect of lack of judicial authorization. Said error consisted in alleging, as it was alleged, that part of the property to which the proceedings referred had been acquired by purchase from Cruz Agosto, instead of stating that the purchase was made from her as the legal representative of her minor children.
In accordance with the judgment of the Supreme Court *738of Spain dated December 30, 1875, in order to acquire securely real property or real rights it is indispensable that the vendor shall not only be the owner thereof, but that he shall have civil capacity to alienate the same; and when the alienation is declared null, the record thereof in the registry of property also becomes null.
The Zechini children acquired from the plaintiffs, who now claim restitution thereof, the 13.68 cuerdas of land referred to in the complaint. The latter, as already stated, were owners of said land under lawful title, but as minors they ■did not have legal capacity to alienate it, and neither could their mother do so without the corresponding judicial authorization. For. this reason the alienation was null and, consequently, the record in the registry of property of the dominion of said lands in favor of the defendants is also null. The latter cannot plead the character of third parties to offset the pretensions of the plaintiffs, inasmuch as they intervened in the prosecution of the recorded dominion-title proceedings, and contracted with the plaintiffs, who were incapacitated to contract.
The contract of exchange being, as it is, null, sections 1270 and 1271 of the Civil Code in force, which are a reenactment of sections 1303 and 1304 of the former Civil Code, are applicable to the case. Said sections read as follows:
“Section 1270. When the nullity of an obligation has been declared, the contracting parties shall restore to each other the things which have been the object of the contract with their fruits, and the value with its interest, without prejudice to the provisions contained in the following sections.
“Sec. 1271. When the nullity arises from the incapacity of one of the contracting parties, the incapacitated person is not obliged to make restitution, except to the extent he has profited by the thing or by the sum he may have received. ’ ’
In view of such definite provisions, the defendants must restore to the plaintiffs the lands which they claim from them, with the fruits thereof, the latter not being obliged to make *739restitution to the former, as it has not been proved that they profited by the exchange. It devolved upon the defendants to prove this.
What are the fruits that must be restored to the plaintiffs •with the lands?
To determine the amount received as fruits by the defendants during the 12 years approximately that they have detained the lands claimed from them — that is, from the year 1897, when they were acquired by Zechini, to March 6, 1909, when the complaint was filed — we must consider the testimony of Tomás Monge, Gerardo Baldrich, and of Antonio Zechini himself, and taking it in the sense most favorable to the defendants we may well reach the conclusion that the 13.68 cuerdas of land claimed by the plaintiffs must have rendered the defendants, during the 12 years they detained them, the sum of $1,000 at least.
The defendants cannot pretend that the contract of exchange executed by them with Cruz Agosto in representation of the plaintiffs, being, as it is, null, the latter should reimburse them the sum of $6,000, or any other sum, for the reasons specified in their counterclaim, because not having proved that the plaintiffs profited by the exchange, the latter are not obliged to make restitution as prescribed by the above-transcribed section 1271 of the Civil Code.
Neither has dominion of the lands in question been acquired by prescription by the defendants, in accordance with section 1858 of the Civil Code, and as alleged by them in the supplement to their answer, because, although in this case the parties were present and the 10 years of possession required by said section had elapsed, the requirements of good faith and just title necessary for the purpose were lacking.
The plaintiffs having the right, as they have, to recover the 13.68 cuerdas of land which they acquired by adjudication made to them in the partition of the estate of their deceased father, and said lands being included in an estate of 27.6936 cuerdas, which was the subject of the dominion-title *740proceedings recorded in tile registry of property in favor of tlie Zechini children, it becomes necessary, in order that restitution of the same may be made to the former, to make a division of the property of 27.6936 cuerdas by segregating the share corresponding to the plaintiffs, the difference remaining in favor of the defendants.
The provisions of section 409 of the Civil Code should be applied in the division of said estate, which to-day belongs, properly and jointly, to the defendants and plaintiffs, though in different proportions.
For the foregoing reasons we are of the opinion that it is proper:
First. To declare the lands claimed as theirs in the complaint to be the property of the plaintiffs.
Second. To declare the nullity of the dominion-title proceedings instituted by the defendants so far as the same relates to the lands claimed.
Third. That a division be made of the lands referred to in the dominion-title proceedings instituted by Zechini, and tliat the share corresponding to the plaintiffs be determined and specified.
Fourth.' That said share, once the same is determined and specified, be restored to the plaintiffs.
Fifth. That the defendants pay to the plaintiffs as reimbursement for the products the sum of $1,000.
Sixth. To declare that the defendants have no right to any reimbursement and should pay the costs originating in the first instance.
The judgment appealed from should be reversed and a judgment rendered containing the aforesaid findings.
Bedded accordingly.
Justices MacLeary and Wolf concurred. Justices del Toro and Aldrey did not take part in the decision of this case.
