the spouses). Property acquired by the parties during the marriage is presumed to be community property. See A.R.S. § 25-211 (Supp.1999).
¶ 17 It is undisputed that Husband acquired his interest in the pizza businesses before the parties’ marriage. Thus, that property is presumed to be Husband’s separate property. See id. However, Wife argued, and the tidal court agreed, that, prior to their marriage, the parties had entered an agreement to combine efforts and acquire property jointly.
¶ 18 In Cook v. Cook, 142 Ariz. 573, 578, 691 P.2d 664, 669 (1984), the Arizona Supreme Court recognized the validity of an agreement, express or implied, between unmarried persons to pool resources and share equally in certain assets. See also Carroll v. Lee, 148 Ariz. 10, 12, 712 P.2d 923, 925 (1986). In the absence of an express agreement, we look to the parties’ conduct to determine whether there was an implied contract. See Muchesko v. Muchesko, 191 Ariz. 265, 268, 955 P.2d 21, 24 (1997); Cook, 142 Ariz. at 576, 691 P.2d at 667.
¶ 19 Wife claims the parties entered an agreement to share their assets in 1989. Husband and Wife pooled their resources and maintained joint checking accounts for household expenses. Wife did not contribute financially to the pizza businesses, but did work with Husband for about one year without drawing a paycheck. When the parties refinanced a loan on the pizza businesses, Husband’s accountant included Wife as a co-applicant and listed both parties’ incomes on the personal financial statement submitted to the lender. The accountant also listed the residence and the pizza businesses as joint assets. However, the accountant testified that she did not intend for that designation to constitute an apportionment of the parties’ rights in those assets. We find that the accountant’s characterization of the property does not establish that the parties intended to acquire and hold that property jointly.
¶20 Husband took title to the Prescott residence in his name only and paid the down payment with his separate funds. Wife’s name did not appear on the franchise documents Husband and his stepfather submitted to obtain the pizza business. Wife did not participate in the acquisition of the business.
¶21 Although the parties’ conduct could support an implied agreement to pool their income, their conduct does not suggest an implied agreement to acquire property jointly with those pooled resources. Husband acquired both the residence and the pizza businesses with his separate funds and took title in his name only. This is clearly different from the implied agreements found in Carroll and Cook, in which the parties intended to hold property jointly, purchased property with their pooled resources, and took title jointly. See Carroll, 148 Ariz. at 14-15, 712 P.2d at 927-28; Cook, 142 Ariz. at 576, 691 P.2d at 667.
¶ 22 Finally, the trial court failed to consider the most direct evidence of Husband’s intent: the premarital agreement. The premarital agreement, as agreed upon by Wife, clearly indicates that Husband did not intend to hold the pizza businesses as joint property and sought to retain the separate nature of that property during the marriage. The evidence does not support the trial court’s finding that the parties entered an implied agreement to acquire property jointly. Thus the residence and P & H Enterprises remain Husband’s separate property. We remand to determine the extent, if any, of the community’s interest in these two assets based on what contribution Wife may have made to them. See Cockrill, 124 Ariz. at 54, 601 P.2d at 1338.
Reimbursement for Community Income
¶23 Husband also appeals from the trial court’s award to Wife of $11,916.39 as her share of the community income for 1997. The trial court concluded that, during 1997, when the parties lived apart, the community earned $61,111.02, of which Husband earned and kept $42,471.90. The court concluded that Wife was entitled to reimbursement of her share of the community income. However, the trial court also found that Husband paid the mortgage from the time the parties separated in July 1996, through November 1997, while Wife had exclusive possession of
