delivered the opinion of the Court.
This is an action for a declaratory judgment to determine whether corporate stock purchased with community funds and issued in the names of the husband and wife “as joint tenants with right of survivorship and not as tenants in common” constitutes community property or belongs to the wife as her separate estate upon the husband’s death. The trial court held that the stock is community property, and the Court of Civil Appeals affirmed. 327 S.W. 2d 467. We affirm the judgment of the Court of Civil Appeals.
Mrs. Pearl Hilley, petitioner, and W. E. Hilley were married in 1920 and lived together as husband and wife until his death in 1956. At the time the stock was purchased, W. E. Hilley instructed the broker in petitioner’s presence to have the certificates issued in their joint names and in such manner and form that upon the death of either the securities would belong to the survivor. The certificates as delivered to and accepted by the husband contained the language quoted above. They were thereafter kept in a safety deposit box carried in the joint names of the husband and wife, but the contract with the bank contains no survivorship provision with reference to the box or its contents. Each of the parties had a key to the box and was authorized to enter the same at will. W. E. Hilley, who died intestate, was survived by petitioner and Garland Hilley, respondent. The latter is the son of W. E. Hilley by a former marriage.
Article 2580, Texas Rev. Civ. Stat. 1925,1 provided that where two or more persons held an estate jointly the interest of one who died before severance would vest in his heirs or legal representatives and not survive to the other joint owners. It was held in Chandler v. Kountze, Texas Civ. App., 130 S.W. 2d 327 (wr. ref.), that while the relationship of joint tenancy, including the doctrine of survivorship, was thereby abolished in situations where the same would otherwise have been created by law, the statute did not prevent the grantees in a deed from making an effective agreement among themselves that the property conveyed should pass to and vest in the survivor as at common law. A written survivor-ship contract covering a joint bank account was also upheld in Adams v. Jones, Texas Civ. App., 258 S.W. 2d 401 (no writ). When Article 2580 was carried into and became Section 46 of the *572Probate Code, the language of the earlier statute was preserved with the express proviso that “by an agreement in writing of joint owners of property, the interest of any joint owner who dies may be made to survive to the surviving joint owner or joint owners, but no such agreement shall be inferred from the mere fact that the property is held in joint ownership.” We assume for the purpose of this opinion that in view of the instructions given to the broker by the husband in the wife’s presence, the issuance and acceptance of the stock certificates in their names as joint tenants with right of survivorship constitutes a written agreement within the meaning of the statute.
The Chandler and Adams cases did not involve community property or a survivorship agreement between husband and wife, but there are a number of Texas decisions which bear directly or indirectly on the question here presented. In Shroff v. Deaton, Texas Civ. App., 220 S.W. 2d 489 (no writ), community funds were deposited in a savings and loan association pursuant to an optional share subscription contract signed by the husband and wife. It provided that the stock was held by the association for their account as joint tenants with right of survivorship, and the trial court also found as a fact that a short time before his death the husband delivered the pass book to the wife and made a valid gift to her of all his interest in the stock. The Court of Civil Appeals expressed the view that the survivorship agreement should be enforced in the absence of fraud, undue influence, mistake or other infirmity, but then pointed out that if this conclusion was erroneous the trial court’s finding of a valid gift made shortly before the husband’s death would still stand as determinative of the whole case.
An agreement in substantially the same form was considered in Reed v. Reed, Texas Civ. App., 283 S.W. 2d 311 (no writ), and the court concluded that under our Constitution and statutes the husband and wife have no power to convert their community estate into the separate property of the survivor by such a contract. Three years later in Steffens v. Pollard, Texas Civ. App., 319 S.W. 2d 447 (affirmed on another ground, but now pending on motion for rehearing, [161 Texas 594, 343 S.W. 2d 234,]) the same court refused to follow the Reed case and held on the authority of our decision in Ricks v. Smith, 159 Texas 280, 318 S.W. 2d 439, that building and loan shares purchased with community funds vested in the wife at her husband’s death because of the survivorship provision in the certificates.
The Ricks case involved United States Savings Bonds pur*573chased by the husband with community funds and payable to the husband or wife as co-owners. He predeceased her without having cashed the bonds and after her death a controversy arose as to the ownership of the securities. The Treasury regulations applicable to bonds so issued provide that the surviving co-owner shall be recognized as the sole and absolute owner thereof. In affirming the judgment of the Court of Civil Appeals holding that the bonds vested in the wife at her husband’s death, this Court said:
“* * * we agree with the Court of Civil Appeals that the purchase of the bonds was by a contract which created a property right, — not merely a method of payment for the convenience of the Treasury Department. There is no sanctity of the community property law above that of other types of law. To give supremacy to Federal regulations no more affects community property law than laws of descent and distribution. The solution as to the property rights of the surviving co-owner of ‘or’ bonds rests in contract, and that contract becomes a part of the bonds. The decisions in this jurisdiction cited in the opinion of the Court of Civil Appeals, while not deciding the precise question here presented, are certainly in harmony with the majority rule followed by that court. We, therefore, approve that holding.”
The power of the husband and wife to transmute their community property into property held by the spouses in joint tenancy with right of survivorship has been recognized in other community property jurisdictions where the question has arisen. See Annotation 30 A.L.R. 2d 1241. As will be pointed out later, we are inclined to the view that the marital partners also have that power in Texas, but the question to be decided here is whether they may accomplish this result by purchasing securities or other property and having the same conveyed or transferred to them as joint tenants with right of survivorship.
Article XVI, Section 15, of the Constitution, and Article 4614 of the statutes define the wife’s separate property as that owned or claimed by her before marriage and that acquired afterward by gift, devise or descent. The husband’s separate property is defined in similar terms by Article 4613. Article 4619 provides that all property acquired by either the husband or wife during marriage, except that which is the separate property of either, shall be deemed community property. All marital property is thus either separate or community. If acquired before marriage by any method, or after marriage by gift, devise or descent, it is separate; otherwise it is community. There are only two exceptions. Property purchased with separate funds is separate, Love v. Robertson, *5747 Texas 6, 56 Am. Dec. 41, and community property partitioned in the manner provided in Articles 4624a and 881a-23, becomes separate property.
The stock involved in this case was acquired by purchase during marriage, and by definition became community property unless the survivorship provision inserted in the certificates with the knowledge and consent of the husband and wife converted the same into the latter’s separate property upon her husband’s death. The parties clearly intended that result, but as pointed out in Kellett v. Trice, 95 Texas 160, 66 S.W. 51, “the question whether particular property is separate or community must depend upon the existence or non-existence of the facts, which, by the rules of law, give character to it, and not merely upon the stipulations that it shall belong to one class or the other. Thus, when one spouse passes to the other by gift his or her title to separate property, it could not become the community property of both, because the law declares that property so acquired shall be the separate property of the donee; and a gift by the husband to the wife of his interest in community property would become the separate property of the donee for the same reason. And so property acquired in the name of either spouse during marriage, otherwise than by gift, devise or descent, or in exchange for separate property, would, by force of the statute, be community property. It is true that in the acquisition or afterwards the husband may give to the wife all his interest in the property, and thus, by gift, make it hers; but at last this would be true only because the facts defined in the law exist, and the separate right is derived through a gift, the husband having full power over the community estate.” See also Tittle v. Tittle, 148 Texas 102, 220 S.W. 2d 637. In Cox v. Miller, 54 Texas 16, it was said that while the husband may make a direct gift of his separate property or the community estate to his wife, the spouses cannot by a mere agreement change the character and nature of the rights and interest in property owned or acquired by them from that prescribed by law.
The survivorship agreement made by petitioner and her husband is not effective as a partition under Article XVI, Section 15, because it is not subscribed and acknowledged by both spouses as required in Article 4624a. It also is clear that the securities did not pass to petitioner by devise or descent, and no interest or right therein was acquired with her separate funds. There is nothing to suggest that Mr. Hilley made a gift in praesenti of all his interest in the stock. The parties did not intend that the same should immediately pass to petitioner as her separate property. Instead it was agreed that the securities would be held by the spouses as *575joint owners while both lived and then vest in the survivor upon the death of either.
If their contract is to be regarded as an agreement that the stock would remain community property as long as both parties lived and then pass to and become the separate property of the survivor, it clearly contravenes Article 4610. Persons intending to marry are there prohibited from making any agreement which would alter the legal order of descent. While the literal wording of the statute applies only to ante-nuptial agreements, the courts have extended its terms to post-nuptial agreements as a matter of public policy. See Weidner v. Crowther, 157 Texas 240, 301 S.W. 2d 621, and authorities there cited. Even if we disregard Article 4610 or hold that its provisions do not apply to survivorship agreements, the title which petitioner asserts had its inception in the contract she made with her husband and is therefore deemed to have been acquired during marriage for the purpose of determining its separate or community status. Colden v. Alexander, 141 Texas 134, 171 S.W. 2d 328; Creamer v. Briscoe, 101 Texas 490, 109 S.W. 911, 17 A.L.R. N.S. 154, 130 Am. St. Rep. 869; MacRae v. MacRae, Texas Civ. App., 144 S.W. 2d 320 (wr. ref.) If petitioner now owns the stock as her separate property, it must be the theory that when the same was purchased she acquired as a gift from her husband the right or interest therein which ripened into absolute ownership upon his death.
A gift is a transfer of property made voluntarily and gratuitously. When an inter vivos transfer is made to either or both of the spouses during marriage, the separate or community character of the property is determined by looking to the consideration given in exchange for it. Any right, title or interest acquired for a valuable consideration paid out of the community necessarily becomes community property, and this is so whether the transfer be made by some third person or by one of the marital partners to the other.
The parties here did not merely agree that petitioner would own the securities in event she survived; it was also stipulated that the stock would vest in the husband if petitioner died first. Prior to the making of this agreement, each spouse owned a community one-half interest in the money used to purchase the stock. If the agreement had not been made, each would have acquired a similar interest in the stock with all of the rights and powers incident thereto. Each would have had the power to dispose of his or her interest by will or to permit the same to pass and vest in accordance with the statutes of descent and distribution. Under the terms of their contract if the same is effective, each relinquished at least some of the legal incidents of community owner*576ship and received in lieu thereof the right to become absolute owner in the event he or she survived the other contracting party. If they became joint tenants, it is by virtue of a transaction in which each surrendered a community interest in exchange for the interest of a joint tenant. Aside from the fact that their life expectancies might not be the same, the right or interest acquired by the husband is no less valuable than that received by the wife. The detriment to the husband is no greater than that suffered by the wife. There is no gift then but an attempted transfer of a survivorship right or interest from each spouse to the other for a valuable consideration. Since the consideration paid by each is derived from the communitly estate, the right or interest which each expected to acquire necessarily remains part of that estate.
In this respect their agreement is not materially different from the deed involved in Pevehouse v. Lubbock National Bank, Texas Civ. App., 79 S.W. 2d 1107, 1108 (no writ). Community land was conveyed by the husband to his wife in consideration of her relinquishing all rights to other community property. It was held that the land which the deed purported to convey remained the community property of the parties, and the court said:
“This instrument does not evidence a gift by the husband to the wife, since ‘gift’ means a voluntary transfer of property by one party to another without any consideration. If there is a consideration for the transfer, the rights of the parties to the trnasaction are contractual and determined by the law of contracts. Kearse v. Kearse et al. (Texas Com. App.), 276 S.W. 690, 691; Brito v. Slack (Texas Civ. App.) 25 S.W. 2d 881. * * * This instrument constituted an agreement between the husband and wife to divide or partition their community property and create therefrom a separate estate for each, which, so long as they continue their marital relation, is not authorized by law.”
Although supremacy of Federal regulations was mentioned in the majority opinion, the holding of the Ricks case is based on the premise that a husband who uses community funds to purchase U. S. Savings Bonds and has the same issued in the names of the spouses as co-owners thereby makes a contract with the government for the benefit of a third party, the wife. It stems from Edds v. Mitchell, 143 Texas 307, 184 S.W. 2d 823, 158 A.L.R. 470, where “p. o. d.” bonds purchased by a life tenant with power of disposition were likened to a policy of life insurance. The opinion in the Edds case states that a life insurance policy for the benefit of another is perhaps the best illustration of a contract for the benefit of a donee beneficiary, and that the situation of the parties *577to the bonds then under consideration was substantially the same as that of the parties to an insurance policy.
After further consideration of the question, we are convinced that the Ricks decision cannot be reconciled with the provisions of our Constitution and statutes. The “contract” which a purchaser of bonds makes with the government does not simply provide that the securities shall become the property of the other co-owner at the purchaser’s death. It stipulates that if either co-owner dies, the surviving co-owner shall be recognized as sole and absolute owner. This is nothing more than a survivorship agreement although the contracting parties are usually the purchaser and the government rather than the two co-owners. Under the provisions of the Probate Code, the interest of a joint owner who dies may be made to survive only by agreement of the joint owners in writing. As applied to community property, the statute means that the interest of one spouse cannot survive to the other except by contract of the husband and wife. Such an agreement when made is for the mutual benefit of the contracting parties, and there is no semblance of a gift even though some third party may also agree to recognize the survivor as absolute owner. The fact that a third person is involved in the transaction, either as grantor, transferor, borrower, issuing corporation, depository, or otherwise, is thus of no legal consequence. Dealings with a third party cannot give rise to a survivorship interest unless the joint owners have the power to and do make an effective written contract so providing. There is no basis for saying that the spouses have even attempted to make such an agreement when one buys government bonds without the knowledge or consent of the other.
It is clear that the Federal regulations do not override our local laws in matters of purely private ownership where the interests of the United States are not involved. Bank of America National Trust & Savings Ass’n. v. Parnell, 352 U.S. 29, 77 Sup. Ct. 119, 1 L. Ed. 2d 93. We might continue to treat “or” bonds purchased with community funds as though they were legally analogous to a life insurance contract and look to the insurance decisions for precedents in determiinng the ownership of such securities after the death of one co-owner. This or some equally unrealistic approach seems to be the only alternative to overruling the Ricks case if title is to vest in the husband when the wife dies first. Before Article 23 was amended to provide that the word “property” as used in the statutes would include life insurance policies and the effects thereof, it was generally held that in the absence of fraud the proceeds of a policy on the life of one spouse became the property of the designated benficiary although the premiums were *578paid with community funds. This was so even where the policy insured the wife’s life in favor of her husband. The courts reasoned that an insurance contract is not property, and that the policy proceeds paid to the husband after the death of the insured wife were not acquired during marriage and therefore became his separate property. It was said that the husband as manager of the community was authorized to purchase the contract with community funds and that there should be no interference with his statutory right of control unless it was exercised in fraud of the wife’s rights. See Martin v. McAllister, 94 Texas 567, 63 S.W. 624, 56 L.R.A. 585; Volunteer State Life Ins. Co. v. Hardin, 145 Texas 245, 197 S.W. 2d 105, 168 A.L.R. 337; Warthan v. Haynes, 155 Texas 413, 288 S.W. 2d 481. On the other hand the cash surrender value of a policy purchased with community funds was regarded as community property. Womack v. Womack, 141 Texas 299, 172 S.W. 2d 307. And the policy proceeds were treated as community property for inheritance tax purposes. Blackmon v. Hansen, 140 Texas 538, 169 S.W. 2d 962.
The decided cases demonstrate the difficulties that were encountered once the courts refused to recognize the property aspects of life insurance. There is no material difference between “or” bonds and other types of property, and any departure from established principles of community property law in dealing with the same will almost certainly lead to confusion and uncertainty as well as inconsistent or undesirable results in particular cases. The insurance decisions suggest that the wife’s estate can be protected when she has been defrauded by her husband, but it will usually be difficult or impossible to establish actual fraud and we do not anticipate that constructive fraud will be defined with such clarity as to provide a satisfactory standard that will insure even reasonably fair treatment of the marital partners and their estates in the various situations that may arise. These considerations lead us to the conclusion that the Ricks case should be overruled, and we will not follow the same where “or” bonds are purchased with community funds and issued in the names of the spouses as co-owners. See Slater v. Culpepper, 222 La. 962, 64 So. 2d 234, 37 A.L.R. 2d 1216; In Re Allen’s Estate, 54 Wash. 2d 616, 343 Pac. 2d 867.
This does not require that the holdings of Chamberlain v. Robinson, Texas Civ. App., 305 S.W. 2d 817 (wr. ref.), or McFarland v. Phillips, Texas Civ. App., 253 S.W. 2d 953 (wr. ref. n.r.e.) be disturbed. Community property apparently was not involved in those cases, and there seems to be no legal impediment to recognition of a contract for the benefit of a third party *579when the bonds are acquired with the purchaser’s separate funds. The case in which bonds are purchased by one spouse with community funds and issued in his or her name and that of some third person as co-owners will be decided when it arises.
We do not think the Legislature in amending Article 2580 intended to modify other statutes and provide that separate ownership might result from a transaction which does not meet the requirements of Articles 4613, 4614, 4619, 4624a and 881a-23. In the first place, any such attempt could not be effectual in so far as the wife is concerned. Under the Constitution, property which she acquires during marriage in any manner other than by gift, devise, descent, purchase with separate funds, or partition as authorized by Articles 4624a and 881a-23, does not and cannot be made to constitute her separate property. Arnold v. Leonard, 114 Texas 535, 273 S.W. 799. In the second place and while we do not attempt to decide the question here, it seems that our Constitution and statutes already provide a method whereby the spouses may arrange for property which once constituted part of their community estate to vest in the survivor if the necessary formalities are observed. Community property may be partitioned in the manner provided in Article 4624a, and the portion set apart to each spouse thereupon becomes his or her separate estate. Article 4614 provides that the wife, if she is at least twenty-one years of age and elects in the manner set out therein, shall have the sole management, control and disposition of her separate property, and in connection therewith may contract without the joinder of her husband. If the wife thus acquires power to contract with the husband regarding her separate estate, there apparently is no legal reason for saying that they cannot make an effective survivorship agreement covering property separately owned by either or both. Under such circumstances the survivorship right or interest acquired by each at the time of making the contract would be by gift or purchase for a consideration paid out of separate property.
An amicus curiae brief suggests that the parties should be presumed to have intended to take any intervening steps that might be necessary to accomplish the result they desired. We are urged to say that Mr. Hilley first gave the community funds to petitioner and that the latter then used her separate property thus acquired to purchase the stock and create a joint tenancy with her husband. This argument, which has already been answered by the opinion in Kellett v. Trice, supra, implicitly recognizes that the agreement in the present case can be upheld only by resorting to legal fiction. A transaction in which each party receives some*580thing of value for that which is relinquished has none of the earmarks of and cannot be given the same legal effect as successive and unrelated gifts. We agree with the Court of Civil Appeals that instead of becoming petitioner’s separate property upon her husband’s death ,the stock passed and vested in accordance with the laws of descent and distribution applicable to community property. The question whether an issuing corporation will be protected when it deals with the survivor without notice that the stock was purchased with community funds is not presented or decided.
The judgment of the Court of Civil Appeals is affirmed.
