RICKY Q. QUILALA, petitioner, vs. GLICERIA ALCANTARA, LEONORA ALCANTARA, INES REYES and JOSE REYES, respondents.
x x x.
Under Article 749 of the Civil Code, the donation of an immovable must be made in a public instrument in order to be valid, specifying therein the property donated and the value of the charges which the donee must satisfy. As a mode of acquiring ownership, donation results in an effective transfer of title over the property from the donor to the donee, and is perfected from the moment the donor knows of the acceptance by the donee, provided the donee is not disqualified or prohibited by law from accepting the donation. Once the donation is accepted, it is generally considered irrevocable, and the donee becomes the absolute owner of the property. The acceptance, to be valid, must be made during the lifetime of both the donor and the donee. It may be made in the same deed or in a separate public document, and the donor must know the acceptance by the donee.
In the case at bar, the deed of donation contained the number of the certificate of title as well as the technical description as the real property donated. It stipulated that the donation was made for and in consideration of the “love and affection which the DONEE inspires in the DONOR, and as an act of liberality and generosity.” This was sufficient cause for a donation. Indeed, donation is legally defined as “an act of liberality whereby a person disposes gratuitously of a thing or right in favor of another, who accepts it.”
The donee’s acceptance of the donation was explicitly manifested in the penultimate paragraph of the deed, which reads:
That the DONEE hereby receives and accepts the gift and donation made in her favor by the DONOR and she hereby expresses her appreciation and gratefulness for the kindness and generosity of the DONOR.
Below the terms and stipulations of the donation, the donor, donee and their witnesses affixed their signature. However, the Acknowledgment appearing on the second page mentioned only the donor, Catalina Quilala. Thus, the trial court ruled that for Violeta’s failure to acknowledge her acceptance before the notary public, the same was set forth merely on a private instrument, i.e., the first page of the instrument. We disagree.
The pertinent provision is Section 112, paragraph 2 of Presidential Decree No. 1529, which states:
Deeds, conveyances, encumbrances, discharges, powers of attorney and other voluntary instruments, whether affecting registered or unregistered land, executed in accordance with law in the form of public instruments shall be registrable: Provided, that, every such instrument shall be signed by the person or persons executing the same in the presence of at least two witnesses who shall likewise sign thereon, and shall be acknowledged to be the free act and deed of the person or persons executing the same before a notary public or other public officer authorized by law to take acknowledgment. Where the instrument so acknowledged consists of two or more pages including the page whereon acknowledgment is written, each page of the copy which is to be registered in the office of the Register of Deeds, or if registration is not contemplated, each page of the copy to be kept by the notary public, except the page where the signatures already appear at the foot of the instrument, shall be signed on the left margin thereof by the person or persons executing the instrument and their witnesses, and all the pages sealed with the notarial seal, and this fact as well as the number of pages shall be stated in the acknowledgment. Where the instrument acknowledged relates to a sale, transfer, mortgage or encumbrance of two or more parcels of land, the number thereof shall likewise be set forth in said acknowledgment.” (underscoring ours).
As stated above, the second page of the deed of donation, on which the Acknowledgment appears, was signed by the donor and one witness on the left-hand margin, and by the donee and the other witness on the right-hand margin. Surely, the requirement that the contracting parties and their witnesses should sign on the left-hand margin of the instrument is not absolute. The intendment of the law merely is to ensure that each and every page of the instrument is authenticated by the parties. The requirement is designed to avoid the falsification of the contract after the same has already been duly executed by the parties. Hence, a contracting party affixes his signature on each page of the instrument to certify that he is agreeing to everything that is written thereon at the time of signing.
Simply put, the specification of the location of the signature is merely directory. The fact that one of the parties signs on the wrong side of the page, that does not invalidate the document. The purpose of authenticating the page is served, and the requirement in the above-quoted provision is deemed substantially complied with.
In the same vein, the lack of an acknowledgment by the donee before the notary public does not
also render the donation null and void. The instrument should be treated in its entirety. It cannot be considered a private document in part and a public document in another part. The fact that it was acknowledged before a notary public converts the deed of donation in its entirety a public instrument. The fact that the donee was not mentioned by the notary public in the acknowledgment is of no moment. To be sure, it is the conveyance that should be acknowledged as a free and voluntary act. In any event, the donee signed on the second page, which contains the Acknowledgment only. Her acceptance, which is explicitly set forth on the first page of the notarized deed of donation, was made in a public instrument.
It should be stressed that this Court, not being a trier of facts, can not make a determination of whether Violeta was the daughter of Catalina, or whether petitioner is the son of Violeta. These issues should be ventilated in the appropriate probate or settlement proceedings affecting the respective estates of Catalina and Violeta. Suffice it to state that the donation, which we declare herein to be valid, will still be subjected to a test on its inofficiousness under Article 771, in relation to Articles 752, 911 and 912 of the Civil Code. Moreover, property donated inter vivos is subject to collation after the donor’s death, whether the donation was made to a compulsory heir or a stranger, unless there is an express prohibition if that had been the donor’s intention.

 Donations which in accordance with the provisions of Article 752, are inofficious, bearing in mind, the estimated net value of the donor’s property at the time of his death, shall be reduced with regard to the excess; but this reduction shall not prevent the donations from taking effect during the life of the donor, nor shall it bar the donee from appropriating the fruits.
