The opinion of the court was delivered by
Miller, J.:The defendant wife appeals from the judgment of the trial court divorcing the parties and upholding and enforcing an antenuptial agreement. She does not challenge that portion of the order granting a divorce. The principal issue before us is whether the antenuptial agreement is valid and enforceable.
The parties were first married on June 21, 1947. Two' children, Virginia and Joseph, were born of that marriage. The Cowley County District Court, Honorable Jerome Harman presiding, entered a decree divorcing the parties on July 7, 1958. The wife was awarded the home and furnishings, an automobile, the sum of *429$25,000 as alimony, and child support. The alimony and support were payable in monthly installments.
The parties discussed remarriage and set January 22, 1961 as the date for the ceremony. Prior to the remarriage, John Ranney consulted an attorney and the antenuptial agreement which is at the heart of this conflict was prepared. On January 21, 1961, the day before the proposed remarriage, the plaintiff presented to the defendant, in the presence of the minor children, the following agreement which he announced was a prerequisite to the marriage:
“This is an agreement between Helen R. Ranney a single person and John M. Ranney a single person. This agreement made prior to marriage.
“It is our intention to be married. Both of us intend the marriage to be successful, but fully realize in view of past difficulties, it may not.
“In the event for any reason the marriage is dissolved or seperated [sic], then Helen shall have the property she owned at the time of this last marriage and John shall have the property he owned at the time of this last marriage. John shall complete the payment of the alimony awarded Helen in her divorce decree and Helen will make no further claim for alimony, support or division of property.
“In other words both Helen Ranney and John Ranney shall be in the same financial position as they were before the marriage.
/s/ Helen R. Ranney
/s/ John M. Ranney”
While some of the evidence is conflicting, it is clear that Helen signed the agreement, returned it to John, and he placed it in his safety deposit box. Helen did not have the advice of counsel and she denies that she read the agreement prior to signing it.
The second marriage lasted for over eleven years. Then on February 22, 1972, the plaintiff instituted this action for divorce and sought to enforce the antenuptial agreement. Following trial, the court found that both parties knew the extent and value of the property of the other at the time the agreement was entered into; that there was no undue influence, overreaching, duress, threat, deception or fraud; that Helen examined the document, knew it was a property settlement agreement, and signed it voluntarily and of her own free will. The court held that the agreement was enforceable, effective and binding upon the parties.
Helen was awarded the home and furnishings (which had been awarded to her in the first divorce), a “replacement” automobile, and a one-third interest in a business property she had acquired by gift from John dining the remarriage. The court made no division of property and did not award Helen alimony or support.
She raises five points on, appeal, asserting that the court erred *430(1) in its construction of the agreement, (2) in failing to award alimony and to divide the property; (3) in failing to find the agreement void as against public policy; (4) in finding that the agreement was fairly and understandingly made; and (5) in limiting discovery as to' plaintiffs financial condition and refusing to admit evidence thereof.
She contends that the phrase “no further claim for alimony, support or division of property” (emphasis supplied) should have been construed to apply only to any request for an additional share of the property owned by the parties at the time of the first divorce and not as a limitation on any future division of property. This is a strained construction of the phrase and one not in harmony with the explanatory paragraph which follows it. Even in the absence of this agreement, Helen could not have secured additional alimony through the original action, in which the judgment had become final. Our statute then in force was G. S. 1949, 60-1511. Alimony judgments thereunder had to be for a fixed amount and they were final in character. Bourman v. Bourman, 155 Kan. 602, 127 P. 2d 464. Alimony awards, once final, could not be modified or changed thereafter. Calkins v. Calkins, 155 Kan. 43, 122 P. 2d 750; Booth v. Booth, 114 Kan. 377, 219 Pac. 513. The trial court correctly construed the language of the agreement.
The trial court found that the agreement was fairly and understandably made. Defendant points to evidence to the contrary. Suffice it to say that we have carefully reviewed the record and find substantial competent evidence to support this finding of the trial court. Such a finding will not be disturbed on appeal though there is evidence in the record which tends to' support a contrary conclusion. The trial court heard and weighed the conflicting evidence. This court will not reweigh the testimony and substitute its judgment for that of the trier of fact. Service Oil Co., Inc. v. White, 218 Kan. 87, 93, 542 P. 2d 652.
Of the remaining three points, two are dependent upon the other. If the antenuptial agreement is valid, then the trial court properly restricted discovery and evidence as to plaintiffs financial worth, and properly refused the alimony and division of property sought by defendant. We turn to the seminal issue, the validity or invalidity of the agreement.
The terms of the agreement are significant. They provide that in the event the marriage fails, each party should have the property each owned at the time of the marriage; that John would continue *431to pay alimony during the marriage; and that Helen would make no further claim for alimony, support or division of property.
We note that John continued to make the alimony and child support payments through the clerk of the court, and that he paid the alimony judgment in full long before this case was commenced. The evidence is undisputed that Helen used the money so paid for family living expenses, though the trial court found that the family would not have gone without if she had not done so. There is no evidence that she accumulated any savings out of the “alimony” payments, or that she had any funds in her own right at the time of the present divorce other than the proceeds from the sale of the home which was sold pendente lite.
The agreement contains no provision relating to assets acquired during the marriage, unless because of the language prohibiting Helen from seeking further alimony or division of property it tacitly assigns all of such after-acquired property to John. This is the precise result of the trial court’s application of the contract. As we have noted, discovery into the area of John’s holdings was limited and evidence thereon was sparse. However, there are suggestions in the record that his net worth was in excess of one million dollars.
We discussed antenuptial contracts at length in Fincham v. Fincham, 160 Kan. 683, 165 P. 2d 209. Mr. Justice Wedell, speaking for the court, said:
“The general rule in this state is that contracts, made either before or after marriage, the purpose of which is to fix property rights between a husband and wife, are to be liberally interpreted to carry out the intentions of the makers, and to uphold such contracts where they are fairly and understandingly made, are just and equitable in their provisions and are not obtained by fraud or overreaching. Generally speaking, such contracts are not against public policy, although a different rule obtains where the terms of the contract encourage a separation of the parties . . . (Syl. fl.)
“Public policy relating to marriage is to foster and protect it, to make it a permanent and public institution, to encourage the parties to live together and to prevent separation. (Syl. f 2.)
“A separation provision in an antenuptial contract which permits the parties to separate at any time and for any cause whatsoever, whether legal or otherwise, and in which the wife relinquishes all rights she may have against the husband personally and in and to his property, on terms that are unreasonable and inequitable, tends to encourage separation and to defeat the marriage relation, is contrary to public policy and unenforceable by either party.” (Syl. f 3.)
In Fincham, the husband brought suit for divorce and sought to enforce an antenuptial agreement which provided that in the event of a separation, then the husband upon demand would pay *432the wife the sum of $2,000 as a complete settlement of every claim the wife might have against the husband. His financial worth was shown to be $160,000. The court held that portion of the contract providing for a payment of $2,000 in full settlement of all rights and obligations arising out of the marriage to be against public policy, tending to invite and encourage a separation, unreasonable, inequitable and void.
Is the contract before us void for the same reasons? We think it is. It did not invite and encourage Helen to take steps to dissolve the marriage, for though she would retain her home and automobile she would lose all right to support and maintenance for the rest of her life and she would lose all right to share in the assets acquired through the joint efforts of the parties during the marriage. John, however, tended to gain by bringing about a separation. He would lose nothing except his inchoate right in the home, furnishings and car; he would be relieved of all obligation to support Helen; he would retain all property acquired during the marriage; and Helen could make no claim against him. John was not even required to make a token cash payment such as the Fincham agreement provided.
These parties were not once married to others; they had no children by prior marriages to others; and their property is that acquired by their joint efforts during their marriage to each other. The agreement did not contemplate future accumulation of property, and made no provision for the disposition of such property. The provision for the continued payment of “alimony” during the marriage in fulfillment of the husband’s duty of support, both during and after dissolution of the marriage, is clearly a sham and a subterfuge and against public policy. The inadequacy of this provision for support of the wife and the absence of any provision for disposition of after-acquired property, as well as the circumstances of the parties and all provisions of the contract must be considered together in determining whether the contract is fair, just and equitable. As noted above, the provision for payment of “alimony” during the marriage is void, and should not be taken into consideration in construing the overall effect of the agreement. As we held in Bremer v. Bremer, 187 Kan. 225, 356 P. 2d 672, and Fincham v. Fincham, supra, an antenuptial agreement which tends to promote separation or divorce and which is unfair is unenforceable and may be set aside. This agreement would leave Helen with a house and *433car, and no part of the assets acquired through their joint efforts during the eleven year span of the marriage.
Under all of the facts and circumstances here before us we conclude that the agreement entered into on January 21, 1961 is unfair, inequitable, contrary to public policy and unenforceable.
The judgment of the trial court is therefore reversed with directions to determine the value of the holdings of the parties and to enter such order for alimony, division of property and support as justice may require.
