A bill signed Monday by Gov. Jan Brewer gives married couples a tie-breaker preference over singles for state-arranged adoptions.
Under the bill, the state must give married couples a limited preference over single adults when placing children in adoptive homes. It says the preference would apply if all other criteria are equal.
The Department of Economic Security is to consider such factors as possible placements with relatives of the child, established relationships with other people and wishes of children 12 or older.
Social conservatives supported the bill. Gay-rights advocates opposed it.
