Answer
Based on official Jordanian legal texts
Jordanian law distinguishes a virgin (bikr), a previously married woman (thayyib), and a sane woman past a certain age in requiring the guardian's consent. For a virgin's marriage the default is to observe her guardian under the order in Article 14 of the Personal Status Law, so her contract is not ordinarily concluded without regard to her guardian.
However, Article 19 expressly provides that the guardian's consent is not required in the marriage of a thayyib or a sane woman over eighteen years of age, so such a woman may conclude her own marriage. For a virgin, if her guardian withholds her marriage without a lawful justification (ʿaḍl), the right to give her in marriage passes to the judge under Article 18, who permits the marriage provided the dowry is not below the dowry of the like under Article 20.
The requirement of a guardian is therefore not absolute but tied to the woman's status, and the judge may stand in the guardian's place in cases of ʿaḍl.
Assessing the woman's status (virgin or thayyib) and whether ʿaḍl exists remains within the Sharia Court's competence on the facts of each case.
This is a general explanation based on Jordanian Personal Status Law and does not replace advice from a qualified lawyer in a specific dispute.
