Petitioners seek a writ of prohibition to restrain the Superior Court of the City and County of San Francisco, sitting without a jury, from taking any further proceedings with regard to the issues raised by their petition for probate of a “lost or destroyed will” and the answers filed thereto. They contend that the record presents a contest of the alleged will, entitling them to a jury trial of the issues so framed. We conclude from an analysis of the applicable law that their position is sustained.
On March 21, 1951, petitioners filed a petition for the probate of an alleged fraudulently destroyed will of Thomas R. Creely, deceased. A copy of the document alleged to be the last will and testament of the deceased was annexed to the petition. (Prob. Code, §§ 350, 351.) They claimed that prior to the deceased’s death, and without his knowledge or consent, a niece had stolen the will from him and fraudulently destroyed it. The hearing was set for April 12, 1951. *361 Certain heirs at law or next of kin of the deceased filed answers denying many allegations of the petition, including soundness of mind, lack of duress, fraud or undue influence, due execution and existence of the instrument, its fraudulent destruction, and the contents thereof, and praying that the purported will be denied probate. On the day first set for the hearing, petitioners made an oral request and also filed a written demand for a jury trial of the issues of fact raised by this opposition to the will’s probate. On April 26, 1951, the day to which the hearing had been continued, the probate judge refused petitioners' demand and announced his intention to proceed with the hearing without a jury. Thereafter this petition was filed to prohibit him from so doing.
While the code sections dealing with the probate of a lost or destroyed will (Prob. Code, §§350-352) make no mention either directly or indirectly of a jury trial, section 371 of the Probate Code guarantees either party to a will contest a jury trial of issues involving competency of the testator, freedom from duress, menace, fraud or undue influence, due execution and attestation of the will, or “any other question substantially affecting the validity of the will.” Section 371 contains no language confining this guarantee of a jury trial to contests of produced wills. It must follow, therefore, that a jury trial of the issues provided for in section 371, if demanded, is also guaranteed in those cases involving contests of lost or destroyed wills:
It is contended that the “answers” to the petition for probate do not constitute a “contest” of the will. This contention cannot be sustained. Section 370 of the Probate Code provides that: “Any person interested may contest the will by filing written grounds of opposition to the probate thereof at any time before the hearing of the petition for probate, ...” In order to give any effect to these “answers,” they must be deemed “written grounds of opposition.” The probate of wills is purely a matter of statutory regulation (Prob. Code, §301 et seq.), and there is no provision in the code for an answer to a petition for probate of a will. To the contrary, the petition for probate is a proceeding
in rem,
and in a sense ex parte, in which an answer is not contemplated.
(Estate of Latour,
The real parties in interest here rely upon language in the eases pointing out the normal procedure for contest
*362
ing a will
(Estate of Latour, supra,
In arriving at this conclusion, we are called upon to determine a matter which the court in
Estate of Doyle, supra,
found unnecessary to decide. There the written opposition consisted in an averment (p. 565) that “ ‘the deceased did not make, sign, publish, or declare, as his last will,’ the instrument propounded.” There, as here, “No demurrer was interposed to the written opposition, nor was any written answer thereto filed or served.” The court tried the “contest,” and determined that the offered instrument was the last will and testament of the deceased and that it was valid in all respects. On appeal, the court held (
Section 370 of the Probate Code continues to use the permissive words “may demur” and “may answer” which were found in former section 1312 of the Code of Civil Procedure. We conclude that an answer or a demurrer to the contest is not required in such a situation as is presented in the instant case. The averments of the petition and the “answers” thereto denying the allegations of the petition constitute a contest of the will, and petitioners are entitled *363 to a jury trial of the issues so framed. (Prob. Code, § 371.)
It is then contended that, even assuming the “answers” constitute a contest, the trial court should not be prohibited from proceeding without a jury to hear the preliminary proof in support of the petition for probate.
In regard to this matter of procedure, it should be pointed out here that although the instant case involves an alleged fraudulently destroyed will, the procedure must be substantially the same as that followed in cases involving produced wills. As was aptly stated in
McCormick
v.
Jernigan,
There is some confusion in the cases concerning the procedure to be followed when there is a petition for probate of a will and a contest thereof. This is the result of our statutory provisions which have been referred to as “somewhat peculiar”
(Estate of Latour, supra,
If the trial court, in its discretion, is allowed to proceed with the hearing of the preliminary proof in support of *364 the petition for probate in the absence of a jury, two separate proceedings will necessarily result. It will then frequently happen that evidence introduced by the proponents upon the hearing of the preliminary proof before the court alone will have to be repeated before the jury, as such evidence is often material in the consideration of the issues raised by the contest.
On the other hand, nothing is to be gained in leaving to the trial court’s discretion the determination that the contest be tried before the hearing of the preliminary proof. If this procedure is followed, the situation may arise where the jury will find for the proponents on the issues raised by the contest, while the trial court might thereafter conclude that a material matter, not placed in issue by the contest, is not established on the hearing of evidence supporting the petition for probate. These considerations clearly indicate that the interrelated proceedings must be heard at the same time.
In the interest of establishing a definite rule of procedure to be followed under such circumstances, we' believe that it is appropriate for this court to declare that when a will is contested before probate and either party demands a jury trial of any issue as to which the right to a jury trial exists (Prob. Code, § 371) the trial court cannot proceed with any phase of the hearing in the absence of a jury but must impanel a jury at the outset. Thereupon, the proponents of the will must make a prima facie showing that the will was executed in all particulars as required by the Probate Code.
There is language in some of the cases such as
Estate of Relph, supra,
In the instant case, the prima facie showing must include evidence that there was a will (with proof of its contents by at least two credible witnesses) which was fraudulently destroyed prior to the testator’s death and without his knowledge. (Prob. Code, § 350.) If the proponents fail to make such prima facie showing, the court can properly deny the petition for probate and dismiss the contest, but the court must bear in mind the holding of
Estate of Black, supra,
Here, as we have seen, although the pleadings are in-artfully drawn, direct issues are raised by the petition and the “answers” as to the existence of the alleged will and its due execution, its contents, its fraudulent destruction in decedent’s lifetime without his knowledge, the soundness of decedent’s mind, and the presence or absence of fraud, duress, or undue influence. Since all of these issues are either mentioned specifically in section 371 of the Probate Code, or are “questions substantially affecting the validity” of this alleged fraudulently destroyed will as provided therein, petitioners are entitled to have all of them submitted to the jury unless upon the preliminary proof of the will there is “such a dearth of evidence that the granting of a motion for a nonsuit would be proper.”
(Estate of Black, supra,
A question is also raised as to the propriety of petitioners ’ demand for a jury trial because of an asserted failure to comply with the Rules for Superior Courts. (
It is ordered that a peremptory writ issue, prohibiting the probate court from proceeding with the hearing in the absence of a jury, but without prejudice to the court’s power to determine in the first instance the sufficiency of petitioners’ prima facie showing in support of the will as hereinabove indicated.
