Jenni Hermoso will appeal the verdict in the case of former Spain football chief Luis Rubiales, who was fined after being found guilty of a forced kiss on the Women's World Cup-winning player, her lawyer said.
"It is her intention" to appeal, lawyer Angel Chavarria said.
Rubiales said after the verdict on Thursday that he will appeal.
In a case which rocked Spain, prosecutors had sought a prison term of two-and-a-half years for Rubiales - one year for sexual assault and 18 months for coercion for having allegedly put pressure on the player to downplay the incident afterwards.
A judge at Spain's High Court found Rubiales guilty of sexual assault over the kiss and fined him 10,800 euros (£8,900), but spared him a prison sentence.
