What is the ruling on a marriage contract that was not written until the following day, after the couple had presented themselves at the notary's office, and in which "She married herself" was written instead of "Her father married her to him"? Is it obligatory to rewrite the document in this case, despite the hardship?

The marriage is valid if its conditions are met, namely an offer and acceptance between your guardian and the husband or his representative, and with the testimony of two witnesses. Documentation of the contract is not a condition for its validity; rather, documentation is important for safeguarding rights and preventing disputes. What the notary wrote, stating that you married yourself, does not affect the validity of the marriage if your guardian was the one who solemnized the marriage.
