delivered the opinion of the Court.

This suit was brought by the State of California to have transferred to it certain deposits in the Security Savings Bánk which had been unclaimed for more than twenty .years; and to have these declared escheat. The bank and the depositors were ■ named as defendants. The bank was served personally and defended. The depositors were served by publication; but none of them appeared. ^[1] The[*284] bank is a California corporation and has its only place of business there. The last known residences of the depositors are not stated. All the proceedings were in conformity with § 1273 of the California Code of Civil Procedure and § 15 of its Bank Act,:Stat. 1915, c. 608, p. 1106. A judgment for the plaintiff was affirmed by the highest court of the State. State v. Security Savings Bank, 186 Cal. 419. The case is here on writ of error under § 237 of the Judicial Code as amended. The question for decision is whether the statutes violate rights guaranteed a state bank by the Federal Constitution. ^[2] It is claimed that they are obnoxious to both the contract clause and the due process clause.

The substantive provision of the legislation is this: If a bank account has not been added to or" drawn upon by the depositor. for more than twenty years; and no one claiming the money has, within that period, filed with the bank any notice showing his present residence; and the president or managing officer of the bank does not know that the depositor is alive; then the bank shall, upon entry of a judgment establishing these facts, deposit with the state treasure?; the amount of the deposit and accumulations. The suit cannot be begun until after the expiration of the twenty years. The statute does not effect an immediate escheat upon the lapse of the twenty years. It provides for taking over the deposit when so adjudged in the action. A valid claim to a deposit duly made at any time prior to entry of the judgment prevents its transfer to the State. Mathews v. Savings Union Bank & Trust Co., 43 Cal. App. 45, 48. State v. Savings Union Bank & Trust Co., 186 Cal. 294, 298.

The procedural provision is this: The suit is brought by the attorney general in Sacramento County. Upon the bank, personal service must be made. Upon the depos[*285] itors, service is to be made by publication of the summons for four weeks in a newspaper of general circulation published in' that county. With the summons a notice must also be published requiring all persons other than the named defendants, to appear and show cause why the moneys involved in the suit shall not be deposited with the state treasurer. Any person interested may become a party to the suit. The judgment to be entered requires the “ banks to forthwith deposit all such moneys with the state treasurer, to be received, inyested, accounted for and paid out in the same manner and by the same officers as is provided in the case of other escheated property.” For a'period of five years after entry of the judgment any person not a “ party or privy ” .to it may sue the State to recover the money so. received. In the case of infants and persons of unsound mind, the period is-extended for one year after removal of the disability; Code of Civil Procedure, § 1272.

The unclaimed deposits are debts due by a California corporation, with its place of business there. State v. Anglo & London Paris National Bank, 186 Cal. 746, 753; State v. Security Savings Bank, 186 Cal. 419, 423. The. debts arose out of contracts made and tó be performed there. Farmers & Merchants Bank v. Federal Reserve Bank, 262 U. S. 649, 660. Thus the deposits are clearly intangible property within the State. ^[3] Over this intangible property the State has the same dominion that it has over tangible property. Pennington v. Fourth National Bank, 243 U. S. 269; Bank of Jasper v. First National Bank, 258 U. S. 112, 119. It was settled in Provident Institution for Savings v. Malone, 221 U. S. 660, that, where the procedure is appropriate, neither the due process clause, nor any right of the bank under the contract' clause, is violated by a.law requiring it to pay over to the[*286] State as depositary savings deposits which have long remained’unclaimed. Compare Cunnius v. Reading School District, 198 U. S. 458; Blinn v. Nelson, 222 U. S. 1. The contract of deposit does not give the banks a tontine right to retain the money in the event that it is not called for by the depositor. It gives the bank merely .the right to use the depositor’s money until called for by him or some other person duly authorized. If the deposit is turned over to the State in obedience to a valid law, the obligation of the bank to the depositor is discharged. Louisville & Nashville R. R. Co. v. Deer, 200 U. S. 176. It is no concern of the bank’s whether the State receives the money merely as depositary or takes it as an escheat.

The bank’s main contention is that it is denied due process because, owing to defects in the prescribed procedure; depositors will not be bound by the judgment; and, hence, that payment to the State will not discharge the bank from its liability to them. The argument that there is no proper provision for service upon depositors or other claimants is this: If the proceeding is in personam, the law is invalid as to' non-residents of the State, since they are served only by publication; and it is invalid as to residents, because they are served by publication without a prior showing of the necessity for such service. If the proceeding is quasi inrem, the law is invalid as to all-depositors and claimants, because there is no seizure of the res, or its equivalent; because the notice provided for is inadequate and unreasonable; and because it is binding only on parties to the action. If the proceeding is strictly in rem the law is invalid, because it does not provide for such seizure of the res, nor give reasonable notice to depositors and claimants.

The proceeding is not one in personam — at least, not so far as concerns the depositor. The State does not seek to enforce any claim against him. It seeks to have the deposit transferred. The suit determines the custody[*287] (and perhaps the ownership) of the deposit. The state court likened the proceeding to garnishment, and thought that it should be described as quasi in rem. In form it resembles garnishment. In substance it is like proceedings in escheat, Hamilton v. Brown, 161 U. S. 256, 263; Christianson v. King County, 239 U. S. 356, 373; for confiscation, The Confiscation Cases, 20 Wall. 92, 104; for forfeiture, Friedenstein v. United States, 125 U. S. 224, 230, 231; for condemnation, Huling v. Kaw Valley Ry., etc., Co.; 130 U. S. 559; for registry of titles, American Land Co. v. Zeiss, 219 U. S. 47; and libels for possession brought by the Alien Property Custodian, Central Union Trust Co. v. Garvan, 254 U. S. 554. These are generally considered proceedings strictly in rem. But whether the proceeding should be described as being in rem or as being quasi in rem is not of legal significance in this connection. In either case the essentials of jurisdiction over the de-' posits are that there be seizure of the res at the commencement of tne suit; and reasonable notice and opportunity to be heard. Compare Pennoyer v. Neff, 95 U. S. 714, 724; Freeman v. Alderson, 119 U. S. 185, 187; Arndt v. Griggs, 134 U. S. 316; Overby v. Gordon, 177 U. S. 214, 231. These requirements are satisfied by the procedure prescribed in the statutes of California. There is a seizure or its equivalent. And the published summons to' the depositors named as parties defendant is- supplemented by the notice directed to all claimants whomsoever. Moreover, there is no constitutional objection to considering the proceeding as in personam, so far as concerns the bank; as quasi in rem, so far as concerns the depositors; and'as strictly in rem, so far as concerns other claimants. ^[4]

Seizure of the deposit is effected by the personal ¡_orvice made- upon the bank. Provident Institution for Savings v. Malone, 221 U. S. 660. Thereby the res is subjected-[*288] to the jurisdiction of the court. Compare Miller v. United States, 11 Wall. 268, 297, 298; Alexandria v. Fairfax, 95 U. S. 774, 779. The service upon the bank has the same effect as had service of the injunction in Pennington v. Fourth National Bank, 243 U. S. 269; or the service upon the garnishee in Harris v. Balk, 198 U. S. 215, 223; or the application for administration of the debt due an ■absentee in Cunnius v. Reading School District, 198 U. S. 458; or the levy of the writ and return of the fact to the court on attachment of the real estate in Cooper v. Reynolds, 10 Wall. 308. The fact that the claim of the State to the deposit may be defeated by the appearance of the debtor or other claimant does not, as argued, prove that the deposit was not seized. An attachment of real estate 'is a seizure, although it may be dissolved by bankruptcy or otherwise.

The statutory service is reasonable; and the court is required to hear any one who may appear in the suit. The objections urged to the notice are not that insufficient time is allowed for entering an appearance, as in Roller v. Holly, 176 U. S. 398, and Goodrich v. Ferris, 214 U. S. 71, or that the contents of the notice fail to convey the required information, as. in Grannis v. Ordean, 234 U. S. 385. The objections taken are to the order and the place of publication. -It is urged that the notice is insufficient, because service may not be made by publication until it has been shown by affidavit that personal service is im^ possible'or impractical. Such an affidavit is a'common requirement in statutes providing for service'by publication on absent defendants. Compare Romig v. Gillett, 187 U. S. 111; Jacob v. Roberts, 223 U. S. 261. But it is not constitutionally indispensable. The reason for requiring the affidavit is that ordinarily, personal service would be more likely to acquaint a defendant with the pendency of the suit. But here the general facts which underlie the legislation establish the futility of such a re[*289] quirement. ''It may be that in California banks usually endeavor to ascertain the whereabouts of depositors whose accounts have remained' dormant for many years. The statute applies only to deposits in the name of a person who is not known to the president or managing officer of the bank to be alive, whose account has not been added to or drawn upon for twenty years, and who has not filed within that time any notice or claim giving his then residence. The legislature evidently assumed that it would be impossible to serve such depositors personally. The Supreme. Court of the State held that the legislature was warranted in this assumption. The. owners of the deposits were, therefore, treated like persons unknown. Compare Leigh v. Green, 193 U. S. 79. We cannot say that the view entertained by the legislature and the state courts ■was so unreasonable as to constitute a denial of due process.

It is further argued that the publication prescribed is not reasonable notice, because it is made in Sacramento County, instead of in' the. county in which the' bank is located. The legislature apparently assumed that publication in Sacramentó County would be more likely to attract the attention of the depositor, or of those claiming under him, than publication in the city in which the bank was located. Support'for that opinion may be found in the statutes which have required savings banks (and later all banks) to publish annually in a newspaper of the city in which it is located a statement showing the amount of each deposit therein, the name and last known residence of each depositor, and the fact of his death, if known, in all cases where the depositor has not made a deposit or withdrawal for ten years next preceding, unless the depositor is known to be living or the deposit is less than fifty dollars. Stats. 1893, p. 183; Stats. 1897, p, 27. Civil Code, § 583b. Such annual publica[*290] tions, if seen, would be apt to remind a depositor of his account, even if he were not named therein. And if he had died, it might serve as a reminder, or as a suggestion, to his next of kin. The fact that, after nine, or more, such publications in the local newspaper, a deposit remains unclaimed, affords the legislature some basis for thinking that the further publication provided fo’ in these proceedings would be more apt to accomplish the purpose of actual service, if made in the county in which the state capital is located. The highest court of the State deemed the prescribed publication in Sacramento County reasonable notice. We have no ground for saying that it was not. Obviously the question “ is one of local experience on which this court ought to be very slow to declare that the state legislature was wrong in its facts ” or abused its discretion. Patsone v. Pennsylvania, 232 U. S. 138, 144; Adams v. Milwaukee, 228 U. S. 572, 583.

In the opinion below it was suggested that the statute may be construed as permitting a' depositor, although named as defendant in the attorney general’s suit, to make claim as against the State, under § 1272, at any time within the five years (or the extended period) after final judgment, if he did not appear in the suit. A's no depositor had appeared, the point was not passed upon; and the state court expressly left open the rights of depositors and their privies in respect to escheat. State v. Security Savings Bank, 186 Cal. 419, 431. We have no occasion to consider them.
