The section’s own words
(1) (a) The fee for filing any civil complaint or petition invoking the jurisdiction of a court of record not governed by another subsection is $375.
What this means: Quoted from the Utah Legislature's official PDF of the section, which prints it in full. The page also states “Superseded 1/1/2027”: $375 is the fee through December 31, 2026, so ask the court for the fee if you file on or after January 1, 2027.
