What is the ruling on the aforementioned marriage contract that was concluded without a guardian and without specifying the value of the dowry, knowing that the wife is Salafi and embraced Islam 9 years ago, and that this is the established practice judicially in Egypt?

The majority of scholars hold that a guardian (wali) is a condition for the validity of marriage. Therefore, if a woman marries without a guardian, her marriage is invalid. If she does not have a suitable guardian, the Muslim judge marries her, based on the Prophet's (peace be upon him) saying: "So the ruler is the guardian of whoever has no guardian." If a Muslim judge is unavailable, it is permissible for a Muslim man to marry her with her permission. Accordingly, if the woman has a Muslim guardian or a Muslim judge, the contract facilitated by the marriage officiant (ma'dhun) is legally void, and the contract must be rectified by a guardian from her agnates or the religious judge. If the woman's son is an adult, he may marry her, and some scholars validate the marriage conducted by a discerning minor son.
