¶2A couple divorced after over 40 years of marriage. Although the wife had moved to a different state several years prior, the superior court determined that their date of separation was in 2014. The court also recaptured pension payments the two received after this date. The wife appeals, arguing that these and various other aspects of the superior court's property division were erroneous.
¶3The superior court neither erred nor abused its discretion in its determination of the date of separation. And most of the wife's other challenges to the property division are without merit. But we reverse the superior court's failure to make specific factual findings in its recapture analysis.
¶4II. FACTS AND PROCEEDINGS
¶5A. Facts
¶6Gordon Taylor and Tamra Faris were married in 1973. For most of their marriage, they lived in Juneau. Faris spent her entire career working for the federal government, earning a Civil Service Retirement System (CSRS) pension. In 2004 Faris accepted a promotion and moved to Honolulu, Hawaii. She moved to Portland, Oregon, also for work reasons, in 2006 and currently resides there. She retired from her career with the federal government in 2010.
¶7When Faris moved, Taylor remained in Juneau. Taylor held a variety of jobs during his marriage to Faris, including various positions with the State of Alaska that made him eligible for Public Employees' Retirement System (PERS). He retired in 2011 and now draws from a PERS annuity and Social Security.
¶8B. Proceedings
¶91. The divorce trial
¶10In 2013 Taylor filed for divorce. He and Faris reached a settlement agreement in February 2014 and the court entered a divorce decree at that time. Three days later, however, Faris sought to withdraw distribution of property from that agreement.
¶11The superior court held five days of trial on the couple's property division in late 2015 and early 2016, after the settlement agreement had broken down. The court issued an order dividing the marital estate in May 2017. It concluded that the parties had not separated until 2014, when they divorced.
¶12To divide the marital estate, the superior court first determined the properties available for distribution. These included two marital properties: a home in Juneau and a second home in Portland, Oregon.
¶13The court then valued and distributed the remaining property, finding it "equitable to divide the estate with 50% of the assets awarded to each party." This split required dividing the parties' pension payments between them so that each would receive the same monthly income. The court heard expert testimony on the value of each party's pensions, but the testimony conflicted. The court elected to split the monthly pension payments in half, using a qualified domestic relations order (QDRO).
¶14The court also considered the pension payments the parties had received since the date of separation in 2014. The court calculated the total benefit each party received from this income and credited that benefit against each party's award, thereby "recapturing" the parties' post-separation pension payments.
¶152. Post-trial motions
¶16After the trial Faris filed several motions for reconsideration, arguing in relevant part that the court erred when it (1) recaptured the CSRS payments received between the date the divorce was granted and the close of *184trial and (2) determined that the date of separation was in 2014.
¶17The superior court denied reconsideration of these issues. It found that both parties had "treated the [post-separation] PERS and CSRS payments as separate assets," effectively converting them to a non-marital form,
¶18Faris appeals the superior court's order dividing the marital estate.
¶19III. DISCUSSION
¶20A. The Superior Court Correctly Determined That The Date Of Separation Was In 2014.
¶21The superior court determined that the date of Faris's and Taylor's separation was February 11, 2014, the date on which the court issued their divorce decree. Faris argues that the court erred in two ways. First she argues that the court "selected the wrong legal rule" when determining the separation date.
¶22Faris also argues that the court abused its discretion when it determined that the separation date was in 2014 because she contends that the parties separated in 2004 when she moved to Hawaii. "Alaska law has defined [the separation date] as the point at which 'the marriage has terminated as a joint enterprise' or when a couple is no longer 'functioning economically as a single unit.' "
¶23Here the evidence suggests that Faris and Taylor objectively separated in 2004, but they lacked the subjective intent to separate until 2014. Faris moved physically apart from Taylor in 2004. But the superior court found that "the parties' marriage ... would have continued if Mr. Taylor did not file for divorce." There is ample evidence in the record to support the superior court's finding, as Faris made repeated statements after 2004 demonstrating an intent not to separate. In 2013 she wrote a letter explicitly stating that she did "not want a divorce." And in January 2014 she wrote an email stating that she "would have never filed for divorce, no matter what, ever. That is still true. I do not want divorce." Even after the superior court issued its divorce decree in February 2014, Faris claimed in an affidavit that the "divorce was entirely [Taylor's] idea" and reiterated that she did "not want to be divorced."
¶24Faris claims that her move to Hawaii evinced a declaration of "financial separation," yet the record indicates that a financial entanglement continued until 2014: Faris and Taylor filed joint tax returns until 2014. They also held properties jointly in a living trust. Faris's own words and actions undermine her argument that she intended to separate in 2004. The superior court did not abuse its discretion in determining that the date of separation was in 2014.
¶25B. The Superior Court Did Not Clearly Err When It Determined That The Portland Home Was Marital Property.
¶26It is uncontested that the parties' Portland, Oregon property was purchased in 2006. "Generally, 'all assets acquired by the parties during their marriage are marital property' except for gifts and inheritances."
¶27C. The Superior Court Did Not Clearly Err In Its Valuation Of The Juneau Home.
¶28At trial Faris argued that the parties' Juneau property could be subdivided, and thus it had a higher value than the $450,000 submitted by Taylor. The court found this suggestion to be "purely speculative." It reasoned that "[s]ince Mr. Taylor has not subdivided the land, built the necessary driveway, or otherwise taken any concrete action to solidify this intention, the court cannot accept Ms. Faris's $505,000 valuation for the [Juneau] property." The court rejected Faris's valuation and adopted Taylor's.
¶29Faris argues that the court erred in its valuation of the property because it failed to consider evidence of Taylor's intention to subdivide the lot.
¶30We have instructed trial courts to avoid property valuations based on speculative improvements to property. In Edelman v. Edelman , we held such a valuation to be clearly erroneous, in part because of the unknown expenses that might be required to complete a subdivision on which the valuation was *186based.
¶31D. The Superior Court Did Not Err By Awarding Faris Half Her Pension.
¶32Faris argues that the superior court erred by not awarding her 100% of the payments from her CSRS pension. She contends that the parties' 2014 divorce decree incorporated a settlement agreement that made such an award. She contends that the terms of the settlement are still effective.
¶33But Faris unilaterally sought withdrawal from that settlement. And the superior court later vacated the property distribution order and findings that had been based on the settlement. The superior court did not revive the settlement when it determined that the date of separation was in 2014. Accordingly the superior court did not err by distributing Faris's pension payments between Taylor and herself.
¶34E. The Superior Court Did Not Abuse Its Discretion When It Used A QDRO To Divide Future Pension Income.
¶35The superior court divided the parties' pensions evenly, using a QDRO, so that both parties would have the same monthly income. When explaining how this income would be divided, the court referenced the parties' expert witnesses, who assigned conflicting valuations to each of the pensions. The court concluded "that the equities in this case necessitate the equalization of income between the parties."
¶36Faris argues that the court's division is incorrect because the court treated the pension income separately from the estate. She contends that the court should have instead determined the present value of the pension plans and included this within the estate. We review allocation of property for abuse of discretion; "[w]e will not disturb the [superior] court's allocation unless it is clearly unjust."
¶37We have stated that it is not an abuse of discretion for a superior court to use a QDRO when the evidence does not permit an accurate valuation of the pensions.
¶38F. The Superior Court Did Not Perform An Adequate Recapture Analysis.
¶39Parties who control a marital asset during separation may be required to compensate the other party if they dissipate or waste the asset or convert it to non-marital form.
¶40Here the superior court recaptured the total reduced retirement pay Faris received between the date of her separation from Taylor and the marital estate's final division in May 2017.
¶41We review an order of recapture for an abuse of discretion.
¶42Here the superior court did not make "any findings about what [the parties] actually did with [their] pension income[s]."
¶43IV. CONCLUSION
¶44We VACATE the superior court's decision on the recapture of the retirement pay received between the date of separation and the final property division order and REMAND for clarifying findings on this issue. Based on its recapture decision, the court is authorized to modify the property division order to the extent necessary to effect an equitable division. We AFFIRM on all other issues raised in this appeal.
