If an answer is filed, trial shall be on the issues made. If no answer is filed, trial shall be ex parte, but defendant is required to prove every allegation of the petition. If the jury (or if a jury is waived, the court) finds in favor of defendant, it shall assess:
(1) The value of the land at the time of the assessment, irrespective of the improvements put upon the land by defendant or those under whom he or she derives, and if any, the injury done to the land by defendant or those under whom he or she derives.
(2) The value of the permanent improvements at the time of the assessment.
(3) The injury, if any, done to the land by defendant or those under whom he or she derives.
(4) The value of the use of the land by defendant between the time of the judgment in ejectment and the time of the assessment or if defendant has been evicted from or has surrendered the premises, from the time of the judgment to the time of the surrender or eviction. The findings shall be specified separately on each of these matters.
