delivered the opinion of the court.
It appears from a transcript of the evidence that on April 12, 1907, S. E. Hillman made his last will bequeathing to his stepsons, Irvin and William Yager, $1 each, to *77his stepdaughter, Grace Jones, wife of one of the defendants, one share of the capital stock of the defendant bank, devising and bequeathing to the plaintiffs the remainder of his property and nominating the defendant Jones executor. Hillman on July 29, 1907, suffered a paralytic stroke, which with subsequent attacks thereof seriously affected‘his physical condition. On December 10, 1908, he sold and conveyed his farm in Clackamas County, taking as evidence of a part of the consideration the promissory notes referred to which were made payable to him and his wife, Amanda, for $2,000, $1,000, and $775, and maturing in one, two, and three years, respectively, with interest at the rate of 7 per cent perannum and secured by a mortgage of the premises. Hillman’s family thereafter moved to Sherwood, Oregon, where a home was purchased, and the notes mentioned were deposited with the defendant bank. Being confined to his bed and unable to transact any business, he, his wife, and the plaintiffs on December 20, 1908, executed a writing, appointing the defendant Young his trustee, authorizing the person so chosen to receive all money then on hand, to collect the promissory notes as they matured, to incur debts in caring for Hillman during his illness, and at his death to pay over to the legal heirs all moneys remaining, less, however, a reasonable sum as compensation for the trustee’s services. Hillman and his wife on February 10, 1909, entered into an agreement'under seal, whereby they stipulated that the promissory notes in question, and the home in Sherwood, consisting of a house and two lots, should be equally divided between them. Young accepted the trust, received from Hillman in cash $884.36, and exercised control over the one-half interest in the promissory notes. Hillman’s family relations were not pleasant, and in consequence thereof Young acting as his trustee, made an agreement with Jones whereby the latter stipulated to care for, *78board, and lodge Hillman during the remainder of his life. Mrs. Hillman testified that for such service Jones was to receive $1 a day, unless her husband should become more infirm, when a greater compensation would be required, which sums were to be paid from the trust fund. Jones testified that no sum was agreed upon, but that he was to be well paid for his services. Pursuant to the terms of the contract, Hillman on February 12, 1909, was taken to the home of his stepson-in-law at Newberg, Oregon. Four days after the promissory notes were obtained from the bank and indorsed by Hillman to the order of Young, who was instructed to collect the sums due thereon as they matured, and from one-half thereof to pay Jones for his services during Hillman’s life, and, at his death, to give the remainder to Jones, less, however, a reasonable compensation to the trustee for his services. At the same time Young extended to Jones his promissory note for $1,200 in order to evidence the anticipated claim against the trustee for such care and keeping. Hillman, as a part of the same transaction, executed to Young an assignment of the mortgage which transfer was duly recorded, whereupon the promissory notes were returned to the defendant bank. Hillman died April 11, 1909, and 30 days thereafter his will was admitted to probate, and Jones was appointed executor, and duly qualified for the trust. An inventory and appraisement of Hillman’s estate was filed August 10, 1909, but no mention was made therein of any interest in the promissory notes. This suit was instituted January 17, 1910, the complaint setting forth the facts in substance as hereinbefore detailed, and averring that the executor intentionally omitted from, and failed and neglected to list and have appraised, as part of the testator’s estate, the half of the promissory notes which Jones claims to own; that all the debts of the deceased have been paid, including medical attendance and funeral *79charges, etc.; and that the note for $2,000 has been discharged by the maker who deposited the amount with the defendant bank. A demurrer to the complaint on the ground that it did not state facts sufficient to constitute a cause of suit was overruled, whereupon an answer was filed setting forth the defendant’s theory of the case. A reply to such new matter put the cause at issue, and a trial being held resulted in a decree as hereinbefore stated.
1. It is maintained by defendant’s counsel that an error was committed in overruling the demurrer, which defect was not subsequently waived. Answering over after a demurrer has been overruled waives informal statements in the complaint, but the defense interposed, unless it contains an express admission, cannot supply the omission of a material averment of the plaintiff’s primary pleading which defect is never relinquished if insisted upon. Section 72, L. O. L. Booth v. Moody, 30 Or. 222 (46 Pac. 884); Brown v. Feldwert, 46 Or. 363 (80 Pac. 414); Bade v. Hibberd, 50 Or. 501 (93 Pac. 364). The plaintiffs do not allege that their title to an interest in the promissory notes was obtained by proceedings in the county court in the administration upon the decedent’s estate, and for that'reason it is argued that the complaint is insufficient. The statute declares that except in cases of the occupancy of real property by a tenant under a valid lease, or by a party to whom personal property has been delivered under a contract of bailment, an executor or administrator is entitled to the possession and control of all property of the deceased until the administration is completed, or such property has been surrendered to the heirs or devises by order of the court or judge. Section 1185, L. O. L. The legal principle contended for by defendant’s counsel has been recognized in the following cases: Winkle v. Winkle, 8 Or. 193; Weider v. Osborn, 20 Or. 307 (25 Pac. 715); *80State v. O’Day, 41 Or. 495 (69 Pac. 542); De Bow v. Wollenberg, 52 Or. 404 (96 Pac. 536: 97 Pac. 717).
2. The general rule is that, where jurisdiction of the probate court has once properly attached, no other court will, without special and sufficient reasons, interfere with or go behind its judgments or decrees, except on appeal therefrom or proper review thereof. 1 Woerner, Am. Law Admin., Section 156. A special and sufficient reason as an exception to the principle announced is recognized by our statute, which provides, generally, that whenever the assets of a decedent’s estate are insufficient to discharge the valid claims against it, and it is made to appear that the testator or intestate made or suffered a transfer of his property with an intent to defraud his creditors, it is incumbent upon the executor or administrator to apply to the county court or judge thereof for leave to commence and prosecute to final judgment or decree the necessary and proper suits and actions to have such transfers adjudged or decreed void and the property affected thereby discharged from the effect thereof. Section 1279, L. O. L. If it appears from the petition that the facts adverted to and thus set forth are probably true, leave shall be granted to institute and prosecute the necessary suits and actions. Section 1280, L. O. L. If a sale of the property recovered by the suit or action be sufficient to meet the payment of all claims against the estate, the right to or interest in the surplus, if any, remains as if such proceedings had not been allowed or commenced. Section 1281, L. O. L. It will be noted that the act last referred to compels an executor or administrator to invoke the aid of equity to set aside fraudulent transfers of property by his testator or intestate, whose acts he is not permitted to impeach except for the benefit of creditors of the estate, and, when their just claims against it are liquidated, the residue of the property, or the remainder of the fund arising from *81a sale thereof, renders the fraudulent transfer good as between the parties and their privies, and binding upon, all persons but creditors. 1 Woerner, Am. Law Admin., Section 296.
3. As the authority of a personal representative to maintain a suit or action to set aside transfers of property by a decedent can be exercised only when such alienations are in fraud of the rights of creditors, it must necessarily follow that devisees and heirs in cases of solvent estates, invoking the maxim that there is no right without a remedy, should be permitted to assert their interests to property where transfers thereof by decedents have been induced by fraudulent means or have not been executed with the formalities required by law, and, since the jurisdiction of the probate courts to administer upon the estates of deceased persons is limited to property of which they died seised or possessed, resort must be had to the circuit courts for the protection of their shares.
In Gardner v. Gillihan, 20 Or. 598 (27 Pac. 220), it was held that the probate court was powerless to try a question of title to property as between an administrator and a third person, but that such adjudication, if necessary, must be had in a court of ordinary jurisdiction. To the same effect are the cases of Dray v. Bloch, 29 Or. 347 (45 Pac. 772); In re Bolander’s Estate, 38 Or. 490 (63 Pac. 689); Harrington v. Jones, 53 Or. 237 (99 Pac. 935).
4. The statute proclaims that, when the county court exercises jurisdiction in probate matters, the mode of procedure is in the nature of a suit in equity as distinguished from an action at law. Section 1135, L. O. L. That tribunal in probate matters is a court of general and superior jurisdiction. Tustin v. Gaunt, 4 Or. 305; Farley v. Parker, 6 Or. 105 (25 Am. Rep. 504); Monastes v. Catlin, 6 Or. 119. It is not, however, vested with general equity powers, and, in order to exercise- such *82authority, recourse must be had to a court of chancery, though the subject-matter of the suit may have been indirectly involved in the probate court. Richardson’s Guardianship, 39 Or. 246 (64 Pac. 390); Dunham v. Siglin, 39 Or. 291 (64 Pac. 661); Rutenic v. Hamaker, 40 Or. 444 (67 Pac. 196); In re Roach’s Estate, 50 Or. 179 (92 Pac. 118).
Under the practice prevailing in this State, the complaint states facts sufficient to constitute a cause of suit, and no error was committed in overruling the demurrer.
The remaining question is whether or not the formal assignment to Young of the mortgage, the indorsement to the order of such trustee of a half interest in the promissory notes, and the return thereof to the defendant bank where they remained until after Hillman’s death, was such a transfer to Jones of the title and possession of the negotiable instruments as amounts in law to a donation causa mortis. It will be remembered that the written assignment of the mortgage was executed by Hillman to Young, who caused it to be duly recorded.
5. Without such a formal transfer, however, a proper delivery of the promissory notes would have carried with a surrender of their possession the collateral mortgage given to secure their payment. Druke v. Heiken, 61 Cal. 346 (44 Am. Rep. 553). The decision of this part of the case must therefore rest upon the disposition which Hillman made of the promissory notes.
6. The prerequisites of a valid donation causa mortis are, a gift of personal property must have been made while the donor apprehended the near'approach of death, and it must appear that he did not recover from the illness with which he was then afflicted or escape from the peril then impending. 1-Woerner, Am. Law Admin., Section 60.
7. There can be no valid donation causa mortis without an actual manual delivery to the donee personally or *83to some third person as his agent of the subject of the gift, if it is capable of such delivery, or by some act equivalent thereto whereby the donor parts with all interest in the property. 1 Woerner, Am. Law Admin., Section 61. Exceptions to such delivery exist in cases where the donee already had possession of the property; where the donor did not have the legal title or possession thereof; or where he destroyed the evidence of the donee’s debt to him as a remission of the obligation. 21 Am. Law Rev. 732,' 752.
8. As a corollary from the legal principles thus stated, it follows that, since a donation causa mortis is ambulatory, the validity of the gift can be maintained by the donee or his agent only by taking and holding possession of the property until the death of the donor. 21 Am. Law Rev. 760.
9. A gift causa mortis is revocable at the donor’s pleasure at any time during his life, and is abrogated by the death of the donee before that of the donor. The donation is also annulled by the recovery of the donor from the illness, or by his delivery from the peril which inducing the gift. Woerner’s Am. Law Admin., Section 62.
10. Applying these general rules to the case at bar, it is evident from Hillman’s enfeebled physical condition at the time he indorsed the promissory notes that he apprehended the near approach of death, and that he did not recover from the infirmity with which he was afflicted, but that he died within 60 days after being taken to the home of his stepdaughter and her husband. For the care and attention bestowed pursuant to the terms of the agreement Jones received $185, but neither of the promissory notes nor any part of the proceeds thereof was delivered to him during Hillman’s life. If Young received the notes as the agent of Jones, a delivery thereof to the latter before Hillman died was not *84essential to the validity of a gift causa mortis. Varley v. Sims, 100 Minn. 331 (111 N. W. 269: 8 L. R. A. [N. S] 828: 117 Am. St. Rep. 694: 10 Ann. Cas. 473). If, however, Young was the agent of Hillman, the death of the latter, under the circumstances detailed, severed their relations, and a delivery thereafter by Young of the notes or the fund arising therefrom would not validate the gift causa mortis. Wilcox v. Matteson, 53 Wis. 23 (9 N. W. 814: 40 Am. Rep. 754); Walter v. Ford, 74 Mo. 195 (41 Am. Rep. 312). Thus where a woman in anticipation of death delivered to her agent a number of certificates of stock duly assigned in writing to certain persons, telling him she wished to retain control of the stock and use so much thereof as she might need during her life, but that after her death she desired him to deliver what certificates remained undisposed of to the proper assignees, and thereafter, while living, she received the accrued dividends on the entire stock and disposed of some of the certificates, it was held that there was no gift causa mortis as to the certificates remaining in the agent’s hands after her death. Noble, Adm’r, v. Garden, 146 Cal. 225 (79 Pac. 883: 2 Ann. Cas. 1001).
11. The delivery of a check as a gift causa mortis to a person other than the donee, but for the donee’s use and benefit and with instructions to deliver the same to the donee, is a sufficient delivery to pass the title, though it does not reach the hands of the donee until after the donor’s death. It was held that the person to whom the delivery was made would be presumed, in the absence of any contrary showing, to be the trustee of the donee, and that, where a donation causa mortis is beneficial to the donee and imposed no burdens upon him, acceptance by him would be presumed as a matter of law. Varley v. Sims, 100 Minn. 331 (111 N. W. 269: 8 L. R. A. [N. S.] 828: 117 Am. St. Rep. 694: 10 Ann. Cas. 473). The evidence in the case at bar overcomes the presumption *85that Young, to whom the promissory notes were assigned, was the agent of Jones. As he had been the trustee of Hillman prior to the assignment, the transfer of the notes to him evidences a continuation of such relationship, and since he did not, during Hillman’s life, deliver the notes or the fund arising therefrom to Jones, his authority to do so ceased with the death of Hillman. The attempt thus to bestow his property was an effort on the part of Hillman to make a testamentary disposition thereof in contravention of the statute, and, as it was not valid as a gift causa mortis, the decree should be affirmed, and it is so ordered. Affirmed: Rehearing Denied.
Decided January 21, 1913. (129 Pac. 124.) Mr. Justice Burnett concurs in the result of the opinion.
