Thank you for your question. The answer may vary depending on which Jurist you follow but here are a couple of verdicts of Ayatullah Sistani according to his book Code of Practice for Muslims in the West:
Question: Some Western governments allow the daughter to be independent of her parents, after she has passed the age of sixteen. If she seeks her parents advice, it is only for seeking their opinion or out of respect for them. Is such a virgin girl allowed to marry, be it permanent or a temporary marriage, without the consent of her father?
Answer: If this means that the father has allowed her to marry whomsoever she wants or that he has withdrawn from interfering in the matter of her marriage, it is permissible for her to do so; otherwise, based on obligatory precaution, it is not permissible.
Question: If a woman is over thirty years of age, and still virgin, is it necessary for her to seek the permission of her guardian for marriage?
Answer: If she is not independent, it is obligatory on her to seek his consent. Rather, even if she is independent, she must seek his consent, as a matter of compulsory precaution.
May you always be successful
