Whether a party has waived the right to a jury trial is a question of law, which we review de novo. Balyeat Law, P.C. v. Harrison, 1999 MT 144, ¶ 18, 295 Mont. 13, 983 P.2d 902. When a demand for jury trial is untimely, the district court's decision to grant or deny the demand is reviewed for abuse of discretion. Sebena v. AAA, 280 Mont. 305, 309, 930 P.2d 51, 53 (1996).
