If a girl is prevented from getting married by her wali (father/brother) for no legitimate reason, what can she do? Can she find another wali?

"When you divorce women and they have reached their set time, do not prevent them from remarrying their husbands if they both agree to do so in a fair manner. Let those of you who believe in God and the Last Day take this to heart: that is more wholesome and purer for you. God knows and you do not." (2:232)
