Appellant, claiming to be decedent’s common-law widow, filed a notice of election to take her intestate share pursuant to section 18 of the Decedent Estate Law. Subsequently she entered into a settlement agreement with the executor whereby she was to receive approximately $15,000, in consideration of which she promised to withdraw her notice of election and to give quitclaim deeds to nine parcels of real estate owned by decedent. After delivering one deed, she refused to execute or to deliver the remaining eight. The executor then moved for an order by the Surrogate compelling her to execute and deliver these remaining deeds. In her opposing affidavit, appellant asked to be relieved of the settlement agreement, upon the ground that it was improvident and unconscionable -in that she contends that the executor did not reveal the true value of *129the estate which, she asserts, exceeds $200,000. The Surrogate denied her cross application to be relieved of the settlement, and granted the executor’s motion for an order to compel her to execute the deeds. On appeal, the Appellate Division reversed and remitted the matter to the Surrogate’s Court for a determination after a hearing concerning the validity and effect of the settlement agreement. In a memorandum decision, the Appellate Division said: “ The Surrogate’s Court has plenary jurisdiction to make a full, equitable and complete disposition of all the issues presented in that proceeding, including the question of whether the settlement was binding and effective.”
The executor moved in Surrogate’s Court under section 443 of the Civil Practice Act for a separate, preliminary trial of the issue concerning whether the settlement agreement should be vacated. In granting this motion, the Surrogate said: “ The cross-relief asked for, viz., a trial of all the issues, is denied at this time, in the exercise of discretion, since the trial of the above-stated issue, if adverse to the respondent [appellant here] will end the litigation and render a trial on the merits of the other issue unnecessary.” That determination was affirmed by the Appellate Division and the order of affirmance is the subject of this appeal. Two of the Justices at the Appellate Division dissented upon the ground that the validity of the agreement should not be tried separately for the reason that, in their view, whether she is the widow of decedent would be an important factor in deciding whether the settlement agreement is unconscionable.
No rule of law or vested right of appellant was violated by the exercise of discretion which was made by the Surrogate’s order, affirmed by the Appellate Division, directing that the validity of the settlement agreement should be tried separately in advance of a trial of whether she was decedent’s common-law wife. In asking for the vacation of the settlement agreement, she stated by affidavit that “ I was unaware of the full extent of my husband’s property, which I now believe to be in excess of $216,586.71, the valuation given to the gross estate in the New York State Transfer Tax proceeding as my present attorney advises me * * * which will indicate to this court that the consideration for my release was so inadequate as to be unconscionable.”
*130Nowhere in appellant’s affidavit is it stated that the amount of the estate was misrepresented to her in the negotiations leading to the settlement agreement. Of course, an executor or administrator stands in fiduciary relationship to the beneficiaries of the estate of which he is the personal representative, and it is bis duty to make full and accurate disclosure to his cestuis que trustent of relevant facts and figures concerning the administration of the trust. There may have been an obligation of respondent as executor of his deceased brother’s estate, and the main beneficiary, to disclose to appellant the material facts concerning the estate before this settlement agreement was entered into unless she knew them already. At least, there was such an obligation if she was in reality decedent’s widow. In either event, that is the most that the executor was required to do. That obligation respondent contends was fulfilled. He avers that appellant’s then attorney knew the approximate amount of the decedent’s estate. In fact, it is contended that the estate turnee out to be worth something less than the amount which her attorney was told.
Concerning the amount of the estate, it is true that responden executor stood in a dominant position regarding appellant. His facilities for understanding its value were presumably greatei than hers, although she appears to have worked for decedent ant may have been familiar with the eight parcels of real estate anc their value which she was to deed to respondent under the settle ment agreement. The executor was in an inferior position t< appellant in not having at his command sources of informatioi available to her regarding whether or not she was the common law wife of decedent. She knew what the facts were on tho subject better than anyone else could have known them excep the man whom she claims to have been her husband.
Although the validity of her legal status as widow necessaril; bulked large in offering or consenting to any settlement whic was or might have been made of her claim to take against the wi under section 18 of the Decedent Estate Law, as the dissentin Justices at the Appellate Division said, nevertheless that does no preclude a separate trial of the preliminary issue of whether th settlement agreement should be vacated. That issue depend at the very most which she can claim, upon whether there was full and fair disclosure to appellant of the facts concerning tb *131amount of the estate at the time when she signed the settlement agreement. At that time it had not been established (and has not yet) whether she was legally his widow. The negotiations necessarily were affected by the probability or lack of it that she would be held to have been decedent’s common-law wife by the Surrogate after trial. That was a factor concerning which both executor and appellant had to make up their own minds, with independent legal advice, and about which they could deal and must have dealt at arm’s length. The executor had no fiduciary duty, as has been previously stated, to advise claimant concerning whether she was legally the wife of Ms testator. She had to make up her own mind upon that issue. It was enough for him to keep track of the estate.
Therefore, whether or not the settlement agreement is to be set aside will depend, at most, upon whether the executor faithfully informed appellant concerning the facts regarding the estate at the time when the agreement was made. It will not depend upon what ultimately proves to have been her status as widow. Upon the trial of the preliminary issue, the Surrogate cannot make a settlement for the parties, nor determine whether they should have made this settlement, depending upon hoAV he, the Surrogate, would have appraised the probability or improbability that the common-law wife question would be decided one way or the other. Whether the settlement agreement Avas “reasonable”, “oppressive”, “unconscionable” depends not upon whether it was the amount which the Surrogate might think that she ought to have been paid or to have accepted in settlement gouged by that variable factor. It will be set aside or not depending upon whether she was informed concerning the estate.
For these reasons, we think that the Surrogate and the majority at the Appellate Division did not exceed their powers in holding that whether the settlement agreement should be set aside is an issue that should be tried first. It does not involve an adjudication of her status as widow. If appellant is defeated upon that preliminary trial, the main trial will be unnecessary; she will be obliged (in the absence of some factual situation wMch is not disclosed by this record) to execute and deliver the deeds to the eight parcels of real property as she agreed to do in the settlement agreement. If she succeeds upon the preliminary *132trial, it will then be necessary to proceed to a trial at which her status will be adjudicated as decedent’s lawful widow entitled to her intestate share in the estate, or as a mere intruder entitled to nothing.
There is ample precedent for conducting a preliminary. trial upon the validity of a release or settlement agreement (Matter of Cook, 244 N. Y. 63; Matter of Frame, 128 Misc. 788, Foley, S.; see, also, Matter of Frame, 234 App. Div. 748, affg. the final decree; Warner v. Star Co., 162 App. Div. 458, 461-462).
The order appealed from should be affirmed, without costs, and the question certified answered in the affirmative.
