This is an appeal from an order admitting the will of Emma Ballesio to probate and from an order refusing to distribute her estate to John Ballesio, her son.

The writing admitted to probate as a will was executed on both sides of a piece of paper. On one side was the following, preceded by a date line:

On the reverse side of the sheet was the following:

The contest filed by appellant was based on grounds which were disposed of by findings of the trial court adverse to the allegations of the contest.

It is contended by appellant, as a question of law arising upon the face of the will, that the trial court “erred in its interpretation of the document admitted to probate as the will of Emma Ballesio in holding that the reverse side of said document with the writing thereon constituted a testamentary instrument.” It is said in support of this contention : “The language appearing on the face of the instrument is a clear and unqualified testamentary disposition of the entire estate of deceased to one Ignazio Pontrelli, while on the reverse side of the same instrument appears an unambiguous and unequivocal statement by Pontrelli Ignazio agreeing to do an act himself.” It will be observed, however, as the decedent left a son surviving her, that the “face” of the instrument was incomplete as a testamentary disposition of her estate for the reason that the son is neither* there provided for, nor is an intention there shown to omit to provide for him. The son is mentioned only on the reverse side of the paper. Section 1307 of the Civil Code reads, in part: “When any testator omits to provide in his will for any of his children, . . . unless it appears that such omission was intentional, such child . . . has the same share in the estate of the testator as if he had died intestate.”

It will be observed, also, that here the name of the testatrix and the names of the subscribing witnesses were subscribed to the matter appearing on each side of the paper. This is a material circumstance in determining whether both sides of the paper, taken together, were intended to constitute the will of the testatrix.

Further, no record of testimony is brought to us in aid of the appeal, and we are therefore justified in assuming that the trial court heard such evidence as would furnish support for its order admitting the will to probate. Both sides of the questioned paper were offered for probate, and the trial court found “that said instrument and all thereof, offered as the will of Emma Ballesio, is the will ... as one document.” We may assume in support of the finding, for instance, that there was evidence that the testatrix declared to the subscribing witnesses that both sides of the paper constituted her will.

The entire document bears the reasonable construction that the testatrix, because of the promise of Pontrelli to pay $1,000 to her son, intentionally omitted to provide for him in the will. Section 1307 of the Civil Code is thus satisfied.

Orders affirmed.
