..It is important for us to know, first of all, that if a marriage fulfills the conditions of validity and is free from any impediments, it is a legally valid (Shar'ī) marriage, even if it is not documented. Similarly, if a man divorces his wife while he is of sound mind and willingly chooses to do so, the divorce takes effect, even if it is not documented.
However, we say that documentation in marriage and other transactions is not considered an innovation (bid'ah) in religion; rather, it falls under the category of al-Maṣāliḥ al-Mursalah (unspecified public interests), especially in this era.
The documentation of marriage preserves the rights of the spouses and children from being lost. This is because in most parts of the world today, marriage is not recognized unless it is documented.
• The wife will not inherit from her husband, nor the husband from his wife, unless there is a documented marriage contract.
• The child is not attributed to his father unless there is a documented marriage contract.
• The child will not inherit from his father unless it is proven with official documents that he is the son of the deceased.
• Furthermore, a woman cannot travel for Hajj, which is a pillar of Islam, with her mahram (unmarriageable male relative) unless it is proven with documents that he is her husband, father, or brother.
Thus, you see that many of the interests of the servants of Allah are hindered due to the lack of documentation. This demonstrates that the documentation of marriage is one of the interests that jurists and legal theorists call al-Maṣāliḥ al-Mursalah.
Al-Shāṭibī said in Al-I'tiṣām (1/185): "The Maṣāliḥ al-Mursalah have been acted upon by the righteous predecessors (Salaf), including the Companions and those who followed them. Thus, they are among the established legal principles recognized by the scholars of uṣūl (legal methodology), even though there is disagreement among them regarding them."
For further benefit, we refer the questioner to Fatwa number: 5962 on the website. And Allah knows best.
