Utah lawmakers passed legislation that would prohibit those 15-years and younger to get married.
The bill now sits on Gov. Herbert's desk, awaiting his signature or veto.
House Bill 234 also outlaws marriages with age gaps larger than seven years, and requires 16- and 17-year-olds get judicial and parental approval.
The proposal initially aimed to ban all underage marriages, but it was later amended by Democratic sponsor Rep. Angela Romero.
Current Utah Law says 15-year-olds can marry with judicial approval. 16- and 17-year-olds only need consent from a parent.
