Gov. Gary Herbert has signed House Bill 461 on Tuesday, increasing the waiting period from 24 to 72 hours.
The waiting period would begin when a woman consults with a doctor anywhere in the state. It doesn't have to be the doctor who will perform the abortion.
The bill was passed by lawmakers earlier this month during the final hour of the legislative session.
American Civil Liberties Union of Utah attorney Marina Lowe says the waiting period is potentially unconstitutional because it places an undue burden on women seeking an abortion.
A similar bill in South Dakota has been put on hold by a judge.
