This is a review of a decision 1 of the court of appeals reversing and remanding *242 for further proceedings the property division portion of a divorce judgment of the circuit court for Waupaca county, Judge Jon P. Wilcox, presiding. We reverse the court of appeals.
The issues presented on appeal are whether property inheritеd before the marriage, but transferred into joint tenancy during the marriage, is marital property subject to division under sec. 767.255, Stats., 2 and whether, if the *243 property in joint tenancy was properly considered marital property, the trial court abused its discretion in the division made in the divorce judgment.
Betty аnd John Bonnell were married in 1946. In 1954 Mrs. Bonnell inherited a resort consisting of several lakeside cottages and lots on the Chain O’ Lakes in Waupaca county. The couple moved to the area to manage the resort. After 1960 Mr. Bonnell worked full time as a Wau-paca county trаffic patrol officer, but he devoted much of his spare time over the years to maintaining, renovating, and repairing the resort properties. Mrs. Bonnell ran the resort business, kept the books, and managed the family’s financial affairs. The record supports the conclusion thаt they invested family funds in improving the resort properties and treated the resort as joint property during the marriage.
*244 From 1954 to 1978 Mrs. Bonnell held title to the resort properties. On August 23, 1978, Mrs. Bonnell conveyed the cottage properties to herself and Mr. Bonnell as joint tenants. A divorce аction was commenced by Mr. Bonnell on October 9, 1979. After testimony by Mr. and Mrs. Bonnell at a hearing held December 17, 1980, the trial court found that Mrs. Bonnell, by placing the inherited cottage properties in joint tenancy, intended to make a gift to Mr. Bonnell and that she had made the gift voluntarily and of her own volition. The court further found that the properties thereby became part of the marital estate subject to division in the divorce judgment. In the final division the court awarded two of the cottage properties to Mr. Bonnell and the remaining four to Mrs. Bonnell.
Mrs. Bonnell appealed the portion of the judgment concerning property division to the court of appeals, contending that the trial court improperly awarded some of the cottage properties to Mr. Bonnell. The court of appeals concluded that the creation of the joint tenancy did change the character of the ownership interest in the inherited properties so as to bring them into the marital estate. .However, the court of appeals held that Mrs. Bonnell, by virtue of the nature of a joint tenancy, retained а separate 50 percent interest in the inherited properties, thus leaving only the remaining 50 percent subject to division. Based on this determination, the court concluded that the trial court erred in including Mrs. Bonnell’s retained 50-percent interest in the marital estate. Further, in order fоr Mrs. Bonnell’s share to be subject to division, the statute required the court to find that refusal to divide her inherited property interest would create a hardship for Mr. Bonnell. The court reversed the portion of the judgment dealing with property division and remanded the matter for further findings. *245 Mr. Bonnell petitioned this court for review of the court of appeals’ decision, and we granted the petition for review.
Section 767.255, Stats., provides that a spouse’s inherited property is not to be included as part of the marital estate subject to division in a divorce unless the refusal to include the property would work a hardship on the other spouse. It is undisputed that the six cottage properties were Mrs. Bonnell’s inherited property and, therefore, were not subject to division so long as they retained their character as inherited property. The sole question presented is whether the properties retained their inherited character after they were transferred into joint tenancy in 1978.
We have held in several cases that a spouse can transfer into the marital estate property which would otherwisе be retained as the spouse’s separate property.
See, e.g., Estate of Nickolay,
It is clear that Mrs. Bonnell intended to create a joint tenancy in the subject properties. This is evidenced by a deed executed on August 23, 1978, by Mr. and Mrs. Bon-nell, transferring ownership to “John Bonnell and Betty Bonnell, husband and wife, as joint tenants with right of survivorship.” See secs. 700.19(1) and (2), Stats. More *246 over, the trial record supports the trial court’s finding that Mrs. Bonnell intended to make a gift of the inherited property to Mr. Bonnell. In response to the question why Mrs. Bonnell made the transfer into joint tenancy, she testified:
“Well, I got tired of hearing about how nothing was John’s. I made out a will leaving everything to him if I died, but that didn’t seem to satisfy him. I thought if that would make him hаppy, why I would do that if I could find a lawyer to do it. . . . He didn’t ask me in so many words, he just kept telling me that nothing was his.”
Other jurisdictions have concluded that separate property transferred into joint tenancy becomes part of the marital estate. In
Atkinson v. Atkinson,
We find the rule of these cases to be persuasive because we conclude that the transfer of separate, inherited property into joint tenancy changes the nature of the property *247 interest. Under sec. 700.17(2) (a), Stats., “[e]ach of 2 or more joint tenants has an equal interest in the whole property for the duration of the tenancy, irrespective of unequal contributions at its creation.” Thus, once the joint tenancy was created, both Mr. and Mrs. Bonnell had an equal interest in all of the properties. The properties were no longer solely Mrs. Bonnell’s; rather, they became a single estate owned by both parties. See 48A C.J.S. Joint Tenancy sec. 2 (1981). Once the properties came under the unified ownership of both Mr. and Mrs. Bonnell as joint tenants, they no longer retained their character as Mrs. BonnelPs separate, inherited property. The properties thus became part of the marital estate subject to division under sec. 767.255.
The court of appeals decided that Mrs. Bonnell retained a 50 percent interest in the properties. We conclude that this was incorrect. A joint tenancy is one estate in which each owner has an equal, undifferentiated share of the entire estate. “Each of the joint tenants possesses a present estate, and is seized of the whole estate; he has an undivided share of the whole estate rather than the whole оf an undivided share.” 48A C.J.S.
Joint Tenancy
sec. 22 (1981) (footnotes omitted);
see also Jezo v. Jezo,
Having decided that all the cottage properties were part of the marital estate, we now turn to the issue of whether the trial court abused its discretion in awarding Mr. Bonnell two of the cottage properties. A division of proрerty upon divorce is within the sound discretion of the trial court and will not be reversed on appeal except for an abuse of discretion.
Bahr v. Bahr,
“ ‘An abuse of discretion occurs when the trial court has failed to consider proper factors, has made a mistake or еrror with respect to the facts upon which the division was made, or when the division itself was, under the circumstances, either excessive or inadequate.’ ”
In Matter of Marriage of Jasper v. Jasper,
Mrs. Bonnell contends that in dividing the properties the trial court failed to take into account her age, health, earning power, and education. However, the record shows that in reaching its decision the trial court took into account that Mrs. Bonnell was fifty-sеven years of *249 age and suffering from arthritis and a muscle disease. The court further specifically stated that “ [t] he differential in the property distribution takes into account the property brought to the marriage by [Mrs. Bonnell] as well as her poor physical health and earning cаpacity to allow her to continue or become self-supporting at a standard of living reasonably comparable to that enjoyed during the marriage.” The trial court considered appropriate factors under sec. 767.255, Stats., and we find no abuse of discretion in thе trial court’s division of the marital estate.
By the Court. — The decision of the court of appeals is reversed.
Notes
Bonnell v. Bonnell,
Section 247.255, Stats., 1977 (renumbered to sec. 767.255 by Chapter 32, Sec. 50, Laws of 1979, effective July 20, 1979), provided in pertinent part:
“. . . Any property inherited by either party prior to or during the course of the marriage shall remain the property of such party аnd may not be subjected to a property division under this section except upon a finding that refusal to divide such property will create a hardship on the other party or on the children of the marriage, and in that event the court may divest the party of such property in a fair and equitable manner. The court shall presume that all other property except inherited property is to be divided equally between the parties, but may alter this distribution without regard to marital misconduct after considering:
“(1) The length of the marriage.
“(2) The property brought to the marriage by each party.
“(3) The contribution of each party to the marriаge, giving appropriate economic value to each party’s contribution in homemaking and child care services.
“(4) The age and physical and emotional health of the parties.
“(5) The contribution by one party to the education, training or increased eаrning power of the other.
“(6) The earning capacity of each party, including educational background, training, employment skills, work experience, length of absence from the job market, custodial responsibilities for children and the time and expense necessary tо acquire sufficient education or training to enable the party to become self-supporting at a standard of living reasonably comparable to that enjoyed during the marriage.
“(7) The desirability of awarding the family home or the right to live therein for a reasonable period to the party having custody of any children.
*243 “(8) The amount and duration of an order under s. 247.26 granting maintenance payments to either party, any order for periodic family support payments under s. 247.261 and -whether the property division is in lieu of such payments.
“(9) Other economic circumstances of each party, including pension benefits, vested or unvested, and future interests.
“(19) The tax consequences to each party.
“(11) Any written agreement made by the parties before or during the marriage concerning any arrangement for property distribution; such agreements shall be binding upon the court except that no such agreement shall be binding where the terms of the agreement are inequitable as to either party. The court shall presume any such agreement to be equitable as to both parties.
“(12) Such other factors as the court may in each individual case determine to be relevant.”
Section 767.255 was modified by Chapter 196, Sec. 29, Laws of 1979, effective August 1, 1980, so that the relevant portion in the current statutes reads:
“Any property shown to have been acquired by either party prior to or during the course of the marriage as a gift, bequest, devise or inheritancе or to have been paid for by either party with funds so acquired shall remain the property of such party and may not be subjected to a property division. . . .”
A tenancy by the entirety is essentially a joint tenancy, modified by the common law theory that husband and wife are one person, and survivorship is the predominant and distinguishing feature of each. Black’s Law Dictionary 1314 (rev. 5th ed. 19791.
Mrs. Bonnell, who consulted with an attorney in drafting the joint tenancy deed, could have created a tenancy in common but chose to create a joint tenancy. The court of appeals appеars mistakenly to have treated the properties as a tenancy in common. “A tenancy in -common differs from a joint tenancy in that . . . the tenant in common owns a distinct interest. Each tenant in common holds his interest and his title independently of the *248 other cotenants.” 4 Thompson on Beal Property sec. 1794 at 140 (1979) (footnotes omitted); see also secs. 700.17(3) and 700.20, Stats. However, Mrs. Bonnell did not create a tenancy in common, and, therefore, the court of appeals erred in treating it as such.
