Is it permissible, Islamically, for a couple to renew their marriage contract, or is the first contract sufficient in this case, especially since the first contract was conducted with two witnesses and a notarized lawyer, and without the knowledge of the wife's family, and after a month from the first contract, and based on the couple's desire, the marriage contract will be renewed in the presence of the wife's brothers?

An urfi marriage, if it fulfills the Sharia-stipulated conditions and pillars (such as the guardian, witnesses, offer, and acceptance), is Islamically valid, even if it is not documented by a judge.

However, if the marriage contract was concluded without a guardian for the woman, it is void according to the majority of scholars, and this is the authoritative ruling; a woman is not permitted to marry herself. The Kuwaiti Encyclopedia of Fiqh states: "A mature, sane, free, and رشيدة (of sound judgment) woman is not permitted to marry herself... Rather, the guardian must conduct it, according to the majority of jurists, based on the hadith: 'There is no marriage except with a guardian...'"

Therefore, a contract concluded without a guardian is void, and its rectification requires renewing the contract through the woman's guardian (her father, then her grandfather, then her son, then her full brother, then her half-brother from her father's side, then their sons, then paternal uncles). The new contract will be the valid one.

However, if a woman married without a guardian, in emulation of the Hanafi school of thought and believing in its validity, then the marriage is valid. In this case, there is no impediment to repeating the contract, and the first contract will be considered valid, and the repetition does no harm.
