Idaho R. Civ. P. 38

(a) Right to Jury Preserved. The right of trial by jury as declared by the Constitution or as provided by a statute of the state of Idaho is preserved to the parties inviolate.

(b) Demand for Jury. On any issue triable of right by a jury, a party may demand a jury trial, stating in such demand whether the party will stipulate to a jury of less than 12 persons, but at least 6. The demand may be made by:

(1) serving the other parties with a written demand, which may be included in a pleading, no later than 14 days after the last pleading directed to the issue is served; and

(2) filing the demand in accordance with Rule 5(d)

(c) Specifying Issues. In its demand, a party may specify the issues that it wishes to have tried by a jury; otherwise, it is considered to have demanded a jury trial on all the issues so triable. If the party has demanded a jury trial on only some issues, any other party may, within 14 days after being served with the demand or within a shorter time ordered by the court, serve a demand for a jury trial on any other or all factual issues triable by jury.

(d) Waiver; Withdrawal. A party waives a jury trial unless its demand is properly served and filed. A proper demand may be withdrawn only if the parties consent.
