The decision to grant or deny pre-judgment interest is reviewed to determine whether the district court correctly interpreted the law. DiMarzio v. Crazy Mt. Constr., Inc., 2010 MT 231, ¶ 23, 358 Mont. 119, 243 P.3d 718; Tidyman's Mgmt. Servs. v. Davis, 2014 MT 205, ¶ 13, 376 Mont. 80, 90, 330 P.3d 1139, 1147.
Whether a party is entitled to post-judgment interest is a conclusion of law which we review de novo. Tipp v. Skjelset, 1998 MT 263, P11, 291 Mont. 288, P11, 967 P.2d 787, P11; see also In re Marriage of Debuff, 2002 MT 159, ¶ 15, 310 Mont. 382, 385, 50 P.3d 1070, 1073.
