OPINION
T1 This is Appellant Sherrie D. Wilde's second appeal concerning an alimony modification petition she filed in 1994. In particular, she appeals the trial court's refusal to award her modified alimony retroactive to the date of her modification petition and the trial court's refusal to award her prejudgment interest. She also challenges the trial court's finding that she has the ability to contribute to her support. Finally, she appeals the trial court's denial of her attorney fees and costs incurred at trial. We affirm.
BACKGROUND
2 In 1987, after twenty-five years of marriage, Appellant and Appellee J. Lynn Wilde divorced. In the divorcee decree, Appellant was awarded alimony of $200 a month for seven years. In 1992, in an amended divorce decree, the parties stipulated to increase the alimony to $318 a month.
T3 In August of 1994, Appellant filed a petition to modify the amended decree, seeking an increase in the amount and duration of the alimony. The petition alleged a substantial and material change in cireumstances based on a substantial increase in Appellee's income, a substantial decrease in Appellant's income, and Appellant's contraction of rheumatoid arthritis. Appellee was served with the petition in September of 1994.
1 4 In January of 1995, Appellant lost her job for reasons unrelated to her health. In February, she filed a motion for temporary alimony. She was awarded $800 a month, effective March 1, 1995. Sometime in April of 1995, Appellant obtained part-time employment. In March of 1996, Appellant terminated her employment. Since terminating her employment, she has not made efforts to gain employment.
T5 In November of 1995, Appellant filed an amended modification petition restating her request for increased alimony and aceus-ing Appellee of orchestrating the parties' divorce to deprive Appellant of her fair share of the marital estate (the fraud claim). Appellant then proceeded to conduct discovery of Appellee's assets, requesting financial records from Beneficial International, Inc., of which Appellee is a principal, from "the beginning" of the corporation, and related entities, from 1985.
T6 In March of 1997, during the first trial on the amended modification petition, and in response to Appellee's motion in limine, the trial court barred further inquiry into Appellant's fraud claim. Following the trial, the court concluded that Appellant's arthritis was a substantial, material change in circumstances justifying modification of the alimony award. However, the trial court also concluded that Appellant's arthritis was not an extenuating cireumstance required to support a modification by an amendment to Utah's Divorcee Statute (extenuating circumstance amendment), which became effective during the proceedings. Therefore, the trial court denied Appellant's modification petition and ordered that alimony terminate.
T7 Appellant appealed to this court. We reversed in part, holding the extenuating circumstance amendment did not apply, and remanded for the trial court:
(1) to determine the amount and duration of additional alimony to be awarded to [Appellant]; (2) to determine the amount of attorney fees reasonably incurred on appeal by [Appellant]; and (8) to reconsider whether or not [Appellant] should be awarded attorney fees incurred at trial onthe petition to modify, and if so, the amount thereof, all supported by the required findings of fact.
Wilde v. Wilde,
T8 Following our remand, Appellant filed a petition for temporary alimony, alleging that she had become totally disabled and unemployable. She was awarded temporary alimony of $2,000 a month from March of 1999.
19 A second trial was held on four separate days between August 9 and October 13, 1999. At trial, Appellant sought modified alimony retroactive to the date of her modification petition. To support her claims that she was unable to work to meet her living expenses of $3,200 a month, Appellant offered evidence that the Social Security Administration (SSA) had awarded her disability benefits, effective March 1, 1996. She also offered testimony by two new medical experts, in addition to two experts who testified at the first trial. The experts testified Appellant's arthritis had worsened and she had developed Parkinson's Disease, Shogren's Syndrome, and Fibromyalgia since the first trial. In regard to Appellant's employability, Appellee offered videos showing Appellant performing "normal day-to-day activities" and testimony of a temporary staffing agency sales president and two individuals who had been awarded disability benefits by the SSA but were employed.
1 10 Following the second trial, the court found Appellant had the ability to work part-time and contribute to her support and was voluntarily unemployed. The court additionally found Appellee's earnings had increased since the divorce and he had the ability to pay reasonable alimony. The court therefore awarded Appellant alimony of $1,500 a month, effective November 1, 1999. The court denied Appellant retroactive modified alimony, finding she had received temporary alimony, disability benefits, Medicaid, and support from her friends and her church during the proceedings. Although the trial court awarded Appellant all of the attorney fees and costs she requested for the first appeal, the trial court denied all of the attorney fees and costs she requested for the two trials.
1 11 Following the trial court's ruling, Appellant filed a Motion to Alter or Amend Judgment, for Relief from Judgment, and/or for a New Trial (motion for a new trial). The trial court denied the motion. In June of 2001, Appellant filed this second appeal.
ANALYSIS
I. Retroactive Alimony
T12 Appellant argues an amendment to Utah Code Ann. § 80-8-10.6(2), effective May 1, 2001, following the second trial, requires an alimony modification to be applied retroactively to the date the modification pleading is served. She further argues amended section 30-38-10.6(2) should apply in this case because it clarifies, rather than substantively changes, the statute in effect when Appellee was served. She alternatively argues even if the trial court had discretion, under section 80-38-10.6(2) or the common law, it exceeded that discretion in not awarding her modified alimony retroactive to the date her petition was served.
A. Does the Amendment to Section 30-3 10.6(2) Apply?
113 As a general rule, amendments which " 'affect substantive or vested rights . operate only prospectively" Wilde v. Wilde,
T14 "A substantive law 'creates, defines and regulates the rights and duties of the parties which may give rise to a cause of action.'" Wilde,
115 Appellant does not appear to argue that the amendment to section 80-8-10.6(2) is procedural; rather, she argues the amendment clarifies how section 30-3-10.6(2) should have been understood. " '[Elvery amendment not expressly characterized as a clarification carries the rebuttable presumption that it is intended to change ... existing legal rights and labilities'" Abel v. Industrial Comm'n,
116 As we discuss in section LB., we conclude the amendment to section 30-8-10.6(2) now requires a court that awards retroactive modified alimony to enter a judgment for the retroactive alimony. That judgment begins to acerue interest and may be filed as a lien to secure that judgment. Under prior section 30-8-10.6(2), a trial court "was not required to enter such a judgment. We conclude that this is a substantive change in the law and not a clarification of the prior statute. Thus, amended section 80-3-10.6(2) does not apply in this case.
B. Does the Amendment to Section 30-83-10.6(2) Require that Modified Alimony be Awarded Retroactively?
117 However, even if the amendment to section 30-3-10.6(2) applies in this case, we conclude that the amendment does not eliminate a trial court's discretion to select the effective date of a modification.
[ 18 When Appellant served Appellee with her modification petition, section 80-8-10.6(2) provided:
A child or spousal support payment under a child support order may be modified with respect to any period during which a petition for modification is pending, but only from the date notice of that petition was given to the obligee, if the obligor is the petitioner, or to the obligor, if the obligee is the petitioner.
Utah Code Ann. § 30-3-10.6(2) (1998).
119 We interpreted that section to give courts the discretion to determine both if and when a modified child support award should be made retroactive.
2
See Ball,
120 As amended and renumbered, section 30-3-10.6(2) now provides:
A child or spousal support payment under a child support order may be modified with respect to any period during which a modification is pending, but only from the date of service of the pleading on the obligee, if the obligor is the petitioner, or on the obligor, if the obligee is the petitioner. The tribunal shall order a judgment for the period from the service of the pleadinguntil the final order of modification is entered for any difference in the original order and the modified amount.
Utah Code Ann. § 78-45-9.3(4) (Supp.2000).
121 The amendment retains the sentence this court interpreted in Ball and Crockett, but adds a sentence requiring a trial court to order a judgment for the period from the service of the pleading until the final order, for any difference between the original award and the modified amount. We conclude the retained sentence still provides that support may be modified retroactively with respect to any post-service period, not that it must be. Under the amendment, the trial court is only required to order a judgment for any difference as opposed to the difference during this period. In context, the added sentence merely requires a court to reduce to judgment any award of retroactive support it chooses to make.
122 Our interpretation is sensible given the delay inherent in the normal judicial process. The parties' cireumstances may change, as in the present case, before a hearing on the modification petition can be held; thus, the trial court should be afforded broad discretion. See Trezevant v. Trezevant,
C. Did the Trial Court Exeeed its Discretion in Refusing to Award Retroactive Alimony?
123 Under the statutes discussed above and Utah common law, we conclude trial courts have the discretion to award modified alimony retroactively to the date a modification petition is served. The Utah Supreme Court has suggested that courts have the discretion to retroactively award modified alimony for the period during which a modification is pending. See Marks v. Marks,
$24 Appellant argues if the trial court had discretion, it exceeded its diseretion in refusing to award her modified alimony retroactively. After Appellant filed her modification petition in August 1994, she received $318 a month in alimony, under the amended divorce decree, through October of 1994. Through January of 1995, when she lost her job for reasons unrelated to her health, she was also working full-time or close to full-time. In February of 1995, Appellant's counsel filed a petition for temporary alimony. She was awarded temporary alimony of $800 a month, from March of 1995, until the trial court terminated alimony at the end of the first trial in March of 1997. Between May of 1995 and March of 1996, she worked up to thirty hours a week. Her August 1995 financial declaration indicates she earned $1,097 a month.
11 25 During the twenty-two months following the first trial and while the first appeal was pending, Appellant did not receive any temporary alimony. The trial court found that during this period, Appellant received disability benefits, Medicaid, and assistance from her friends and church.
3
Specifically, after becoming eligible for disability benefits,
T26 Following the first appeal, Appellant was awarded temporary alimony of $2,000 a month, from March of 1999. Following the second trial, she was awarded modified alimony of $1,500 a month, effective November 1, 1999.
T2%7 Appellant argues the trial court should not have "credited" Appellee for the disability benefits, Medicaid, and assistance from her friends and church. We have stated that " 'it is appropriate and necessary for [trial courts] to consider all sources of income'" of the parties in awarding alimony. Breinholt v. Breinholt,
128 Appellant next argues she should be awarded modified alimony retroactively because Appellee consistently delayed the proceedings. This argument was apparently raised in Appellant's motion for a new trial. In denying that motion, the trial court noted "no evidence of delay by either party was presented at ... trial" and the court "did not find or reward [the] delay alleged by [Appellant]."
T29 To challenge the trial court's finding of no delay, Appellant "must demonstrate that the finding was clearly erroneous." See Crockett v. Crockett,
130 We conclude Appellant has failed to meet her obligation to marshal and we thus assume the record supports the trial court's finding. Based upon the totality of the record, we cannot say the trial court exceeded its broad discretion in denying Appellant retroactive alimony. 4
II. Appellant's Ability to Contribute to her Support
131 In the first appeal, we concluded the trial court's finding that Appellant was able to contribute to her support and work part-time was well supported by the evidence. See Wilde v. Wilde,
€32 Appellant maintains that her condition has worsened since the first trial,
9383 Appellant next maintains that medical expert testimony conclusively establishes her inability to work and alleges that the trial court arbitrarily disregarded that testimony in favor of other evidence. "The trial court is free to accept or reject an expert's opinion, and may accord to the witnesses' opinion{s] whatever weight it deems proper." Schindler v. Schindler,
34 The record shows the trial court did not arbitrarily disregard medical expert testimony offered at trial. The court acknowledged the testimony, but was more persuaded by other witnesses. In addition to the medical experts, the trial court considered testimony by a temporary staffing agency sales president that Appellant's skills are in demand and she could earn between $10 and $15 an hour. The trial court also emphasized the testimony of two individuals who, like Appellant, qualify for SSA disability benefits but who work.
1385 The trial court further emphasized Appellant's testimony that she has made no effort to obtain further employment or training or to take advantage of any program with respect to disabilities or workplace variations available to persons with disabilities, but if she were required to take advantage of such training she would. She also testified she is taking medication, her pain is reduced, and she hopes to return to work.
136 The trial court also emphasized that videotapes taken of Appellant in March of 1999 show that she is mobile, animated, and can walk without assistance for extended periods of time. The videos show she can do many normal daily activities given her age and physical condition.
11 37 We cannot say the trial court's finding that Appellant is able to contribute to her support is clearly erroneous. Although experts clearly indicated that Appellant is unable to work, other evidence offered at trial supports the contrary. 5
III. Attorney Fees and Costs Incurred at Trial
138 Appellant argues she is entitled to attorney fees and costs incurred at trial. Trial courts are afforded broad discretion in deciding whether to award attorney fees and costs in modification proceedings. See, eg., Larson v. Larson,
140 The trial court found that Appellant's requests were unreasonable because: (1) "it is impossible to tell from the evidence presented ... [what] portion of the time expended relate[d]" to the modification and the fraud claim; (2) "it is impossible to tell what portion of the time was expended with respect to those issues upon which [Appellant] ... prevailed;" (8) "it is very clear that [Appellant] in this case engaged in overkill to an enormous degree with respect to attorney time, costs, expert witnesses and the like;" (4) "the facts and issues in this matter were not unusually difficult," but Appellant worked "many more hours than what would be reasonable;" (5) "both sides ... filed motions for sanctions and contempt;" (6) "there were violations," primarily on the part of Appellant, "of the Court's pretrial [o]rders and the [rjules of [plrocedure with respect to identification of witnesses and disclosure of exhibits;" and (7) "neither side was ready for trial with respect to their evidence, but both sides were adamant about going [forward]."
{ 41 Appellant first maintains that where a party clearly has need, it is an abuse of discretion to deny any fees and costs because the fees and costs requested are unreasonable. However, Utah appellate courts have denied fees, although the requesting party appeared to have significant need and the other party had the ability to pay, because the requesting party failed to establish the reasonableness of the fees. See Delatore v. Delatore,
{42 Appellant next maintains the trial court exceeded its discretion in determining that her fees and costs were unreasonable because she failed to allocate them between the modification and the fraud claim. In other contexts we have held that the failure to allocate attorney fees between compensa-ble and non-compensable claims constitutes grounds for complete denial. See Jorgensen's, Inc. v. Ogden City Mall,
1 48 Appellant argues even if her counsel was required to allocate fees and costs, her counsel's testimony, affidavit, and itemiza-tions offered as exhibits established that allocation. In essence Appellant argues the trial court should have allocated the fees and costs based on the evidence presented. In support of Appellant's request for fees and costs incurred during the first trial, Appellant's counsel submitted a fee itemization with a few entries indicating fees incurred were related to the fraud claim. He also submitted a cost itemization, but that itemization does not make any distinction between the modification and the fraud claim. In the first trial, Appellant's counsel testified that he could not allocate the fees and costs and did not think it was necessary to do so because the modification and fraud claim were intertwined. He resubmitted this same itemization during the second trial although he had been eross-examined by Appellee's counsel regarding allocating the fees in the first trial. However, during the second trial, Appellant's counsel summarily testified that $4,406.25 of the
144 Given that Appellee's counsel had cross-examined him during the first trial about allocating, Appellant's counsel arguably should have been on notice that he needed to allocate. He could have done so in his motion for a new trial, rather than waiting until his second appeal to submit a new fee itemization as a reply brief addendum. 6 Thus, again we cannot say the trial court exceeded its discretion in basing its denial of attorney fees on a failure to allocate.
145 Appellant next challenges the trial court's findings that her counsel failed to comply with pre-trial orders and rules of procedure and engaged in overkill to an enormous degree with respect to attorney time, costs, and expert witnesses. The see-ond trial was limited, by our remand, to three issues: the amount and duration of modified alimony to be awarded Appellant, reasonable attorney fees and costs on appeal, and attorney fees incurred for the first trial. In retrying the modification, Appellant retained an investigative accountant and again subpoenaed financial records of Appellee, Appellee's employer, and additional entities. These efforts were to establish Appellant's "true income," yet no substantial difference in income was found by the trial court. Therefore, we cannot say that the trial court's findings are clearly erroneous or that the trial court exceeded its discretion in denying attorney fees and costs.
IV. Attorney Fees and Costs on Appeal
946 Appellant seeks attorney fees and costs for this second appeal. "Generally, when a trial court awards fees in a divorce action to a party who then prevails on appeal, that party will also be entitled to fees on appeal." Larson v. Larson,
CONCLUSION
147 We hold the amendment to section 30-3-10.6(2) of Utah's Divoree Statute makes a substantive change in the law, and therefore the amended statute does not apply in this case. We also hold that even if amended section 30-3-10.6(2) applied, it maintains trial court discretion to award modified alimony retroactively for the period following service of the modification pleading. Based on the totality of the record, we conclude: (1) the trial court did not exceed its discretion in denying Appellant's request for retroactive modified alimony; (2) the trial court's finding that Appellant has the ability to contribute to her support is not clearly erroneous; and (8) Appellant failed to establish the reasonableness of her attorney fees and costs, and therefore, the trial court did not exceed its discretion in denying attorney fees and costs incurred at trial. We therefore affirm. Appellant's request for attorney fees and costs for this second appeal is denied.
Notes
. This remand is quite limited and does not seem to require a new trial. However, neither party objected to the scope of the proceedings that followed.
. We had not explicitly stated that section 30-3-10.6(2) applies to alimony as well as child support modifications. However, we conclude that this section applies to Appellant's alimony modification because Appellant was receiving child support when she filed her modification petition and thus sought to modify a "spousal support payment under a child support order."
. Additionally, the trial court found that Appellant's adult son lived with her and gave her $100 per month. However, it is not clear when the son began paying her. The trial court found that a reasonable value for room and board was $400.
. Because we affirm the trial court's denial of retroactive alimony, we do not reach Appellant's claim that she is entitled to prejudgment interest on retroactive alimony.
. Appellant also asks us to modify the alimony awarded to her by $400 a month to reflect the post-trial loss of room and board from her son. The son was paying only $100 a month, and the trial court determined that fair rental value of the room and board was $400. That fair rental value holds constant whether or not the son lives with Appellant. Further, Appellant raised this change in circumstance after her motion for a new trial, in her counter-motion to compel compliance with the court's order. In fact, in support of her motion for a new trial, she indicated her son was still living with her and contributing to her support.
Raising an issue in a post-trial motion fails to preserve that issue for appeal without evidence that the trial court considered and ruled on the merits of the issue. See In re Covington,
. In her reply brief Appellant has offered an entirely new fee itemization. In this itemization Appellant seeks $26,443.75 in fees for both trials. Appellant failed to offer this new itemization below. It is not part of the record; therefore, we refuse to consider it on appeal. See Finlayson v. Finlayson,
