delivered the opinion of the court.
This is an appeal from a judgment entered in the district court, Lewis and Clark County, following a trial to the court, sitting without a jury.
This appeal stems from the granting of an absolute divorce to both parties on the grounds of irreconcilable differences, the property division, and an award of alimony to plaintiff. The divorce per se is not at issue, only the property division and alimony award are questioned by plaintiff.
At the time of trial the parties had been married thirty-two years, their four children had reached majority with one daughter still living with plaintiff, and they had acquired the following property:
A residence in Helena, Montana, with a mortgage thereon;
A residence in Virginia, with a mortgage thereon;
Stocks and securities;
*249Paid up life insurance policies (amounting to $50,000);
Personal property and household goods;
Two automobiles (a Scout and an Oldsmobile); and
Two unimproved lots in Virginia.
Their relative gross incomes at this time were:
Defendant:.$2,000/month — Army pension
$ 1,000/month — real estate salesman
$350/month — rental income
$3,350/month — T ota 1
Plaintiff:.$475/month — Secretary
During the first 27 years of their marriage defendant was a career Army officer, obtaining the rank of Brigadier General at the time of his retirement, and participated in three extended foreign tours of duty in World War II, Korea, and Vietnam. Throughout this time, defendant solely contributed financially to the marriage.
Plaintiff married defendant before finishing college and throughout the marriage managed the household, raised their four children (such responsibilities handled alone during defendant’s foreign tours of duty), entertained at social functions, worked in the Army wifes’ auxiliaries, nurseries, Red Cross relief, and as a voluntary hospital aide. She gained the secretarial employment, mentioned above, after the commencement of this action.
The complaint originally alleged mental cruelty, but was later amended, alleging irreconcilable differences. Plaintiff and defendant were the only witnesses to testify at trial. The district court granted an absolute divorce to both parties, awarded plaintiff alimony of $ 500/month, and divided the property, subject to any indebtedness thereon, as follows:
To the plaintiff:
The residential property in Helena, Montana.
The household goods and furnishings.
*250The 1972 Scout automobile.
To the defendant:
The residential property in Virginia.
The two unimproved lots in Virginia.
The 1969 Oldsmobile automobile.
The stocks and securities were to be divided in kind, or if desired, sold on the market with the proceeds so divided. This division was to be one half to each party of the remainder, after allowing for the credits of each party found by the district court in making the entire property division.
Defendant was also directed, to name the plaintiff irrevocably as beneficiary to $25,000 of the paid up insurance.
Each party was to pay his or her own court costs and attorney’s fees.
The defendant raises four issues:
(1) Whether the district court erred in its property division and alimony award?
(2) Whether defendant’s Army pension was a proper basis for the alimony award?
(3) Whether a finding of fault on the part of defendant is necessary to allow an alimony award for plaintiff?
(4) Whether the applicable alimony statute is an unconstitutional form of sex discrimination?
It is well settled in Montana that a district court has far reaching discretion in resolving property divisions and its judgment will not be altered unless there is a clear abuse of that discretion. Cook v. Cook, 159 Mont. 98, 495 P.2d 591; Francke v. Francke, 161 Mont. 98, 504 P.2d 990; Roe v. Roe, 171 Mont. 79, 556 P.2d 1246.
The district court concluded that plaintiff’s contributions in this 32 year long marriage were the raising of the 4 children, managing the household, entertaining at social activities and volunteering her services to other activities related to defendant’s *251career. Furthermore, a large majority of this was performed alone while defendant was away from home pursuing that career. The district court stated that even though these contributions differed in kind, they were of equal weight to the financial contributions of defendant.
Defendant argues that the findings of the district court did not credit him enough for his financial contributions. However, we find the district court’s findings in complete accord with the modern trend of Cook, Francke, and Roe to consider more than financial contributions to a marriage when dividing the property since marriage is much more than a business relationship.
We find no abuse of discretion in the district court’s judgment which effects an equal property division based upon equal contributions by each party. As stated in Cook, this does not make Montana a community property state. Each case depends upon its own facts and circumstances and this case warranted an equal distribution.
Nor was it an abuse of discretion for the district court to arrive at a value of its own choosing as to the residential property, applying its own inflation value to the purchase price and not that offered by defendant. Defendant also argues the district court improperly valued the household goods and the Virginia lots. We do not agree. There was conflicting testimony on each and the district court resolved this by giving the household goods to plaintiff and the lots to defendant. This was an equitable division.
As for the alimony, neither party disagrees that such an award depends upon balancing the financial needs of one party and the financial ability to pay of the other. Whether or not defendant caused plaintiff to quit college, it is undisputed that she did not finish college and had limited vocational skills. At the time of trial plaintiff had only a fixed net income of $375 per month from a secretarial position while incurring fixed monthly living expenses, exclusive of any house payment, of $650. At the *252same time, defendant had net monthly income of $1,300 from his Army pension and an average monthly income of $1,000 as a real estate salesman. In light of these facts we find no abuse by the district court in awarding $500 per month alimony to plaintiff.
Defendant argues that his Army pension is not property jointly acquired during the marriage and as such is not subject to division whereby plaintiff received a portion. What defendant fails to comprehend is that the district court-made no property division of the pension but directed defendant to pay $500 per month alimony from the pension or “in lieu thereof from any earnings he may acquire in excess of said retirement.” Without addressing whether this pension is jointly acquired property subject to property division, the pension is a source of income to defendant which the district court properly considered in fixing his financial ability to pay alimony as related to the financial needs of plaintiff.
The district court’s award of alimony is not based upon fault by the defendant. As defendant concedes, this Court has held that it is proper to award alimony when an absolute divorce has been granted to both parties as was the case here. Burns v. Burns, 145 Mont. 1, 7, 400 P.2d 642, 645; Stenberg v. Stenberg, 161 Mont. 164, 505 P.2d 110. As stated in Burns:
“* * * The basis for liability for the payment of alimony is the granting of a divorce against the person required to pay it, R.C.M.1947, § 21-139. * * *”
The defendant seeks to have us ignore this language because the divorce was not granted upon one of the traditional fault grounds, but on the ground of “irreconcilable differences”. We reject his argument.
The irreconcilable differences approach was established to base divorce upon the realistic notion that neither party to a broken marriage is totally to blame. By removing the fault concept, highly emotional courtroom confrontations can be replaced by a more rational approach to the divorce process and avoids *253as much unnecessary psychological and emotional stress to the parties as possible. Our interpretation of section 21-139, R.C.M. 1947, in Burns is equally applicable here. As long as the.district court entered the divorce against both parties, the district court properly awarded alimony to the plaintiff. We do not believe the legislature intended to create the illogical situation whereby a party must elect to seek a divorce on the traditional fault grounds and be eligible for alimony, or waive alimony by proceeding under the modern and enlightened irreconcilable differences approach.
The final issue regarding the constitutionality of section 21-139, R.C.M. 1947, is not properly before this Court and we decline to consider it because defendant has failed to comply with Rule 38, M.R.App.Civ.P. Clontz v. Clontz, 166 Mont. 206, 531 P.2d 1003; Grant v. Grant, 166 Mont. 229, 531 P.2d 1007.
The defendant filed his notice of appeal in this action October 10, 1975. The district court record was filed on February 2, 1976. Notice of the constitutional challenge was not filed until September 2, 1976, the same date as the filing of his reply brief. This does not comply with the notice in writing of the constitutional challenge as required by Rule 38, M.R.App.Civ.P.
The judgment is affirmed.
