The legal implications of a mother giving her daughter's hand in marriage can vary depending on the jurisdiction and cultural context. In many countries, the practice of a mother formally "giving away" her daughter in marriage is largely symbolic and not legally binding. Marriage is typically a legal contract between the individuals getting married, and legal procedures related to marriage are governed by the laws of the specific country or state.
In most legal systems, the consent of the individuals getting married is the crucial factor in establishing a valid marriage. Both parties must freely and willingly agree to enter into the marriage contract. Parental involvement, including the symbolic act of a mother giving her daughter's hand in marriage, is often part of traditional ceremonies and customs, but it does not replace the requirement for the actual consent of the individuals involved.
It's important to note that forced marriages, where individuals are married against their will, are illegal in many countries and are considered a violation of human rights. Consent is a fundamental aspect of a legal marriage, and any attempt to force someone into marriage is unlawful.
As marriage laws can vary significantly from one place to another, it's essential to research and understand the specific legal requirements and implications of marriage in the relevant jurisdiction. Legal advice from a qualified professional can also be sought to ensure compliance with local laws and regulations.
