Idaho Gov. Brad Little signed HB 509, barring transgender residents from correcting birth-certificate sex markers
On March 30, 2020, Idaho Gov. Brad Little signed House Bill 509 into law, adding Idaho Code 39-245A and requiring birth certificates to record sex as an immutable, biology-based category fixed at conception. The law forecloses amending a birth certificate's sex field based on gender identity, permitting correction only within one year via a notarized affidavit attesting the original entry misstated a fact at birth, or afterward only through a court finding of fraud, duress, or material mistake of fact. It passed the Idaho House 53-16-1 and Senate 27-6-2 and took effect July 1, 2020, as Session Law Chapter 334.
