If current marriage laws became invalid, the legal framework surrounding marriage would need to be reestablished. The specifics of how this would work would depend on the jurisdiction in question and the reasoning behind the invalidation of the current laws.
Assuming a complete invalidation of all existing marriage laws, new laws would need to be enacted to regulate the legal status of marriages. These new laws could be based on existing laws from other jurisdictions or could be entirely new. They would need to address various aspects of marriage, such as who can get married, how marriages are created, and how they can be dissolved.
The process for getting married would likely involve some form of legal registration or contract, similar to how civil marriages work in many countries today. This would establish the legal rights and responsibilities of the couple and any children they have, as well as the rules governing property and inheritance in the event of a divorce or death.
Depending on the jurisdiction, there may be different requirements for getting married, such as age restrictions, premarital counseling, or waiting periods. The legal recognition of same-sex marriages and non-binary marriages may also need to be addressed.
If marriage status were invalidated, the rules around property division would also need to be reestablished. This would depend on the new legal framework that is put in place to govern relationships between couples.
In the absence of any specific laws, the division of property between a couple who are no longer together would be governed by general property law principles. This means that the couple would need to determine how to divide their property based on the legal ownership of the assets.
If the couple owned property jointly, such as a shared bank account or a jointly-owned home, then they would need to come to an agreement on how to divide this property. If they are unable to come to an agreement, then they may need to go to court to have a judge decide how to divide the property.
If the couple owned property separately, then each person would be entitled to keep their own property. However, if one person contributed to the other person’s property, such as by paying for renovations to a home owned by the other person, then they may have a legal claim to a portion of that property.
Ultimately, the division of property between a couple would depend on the specifics of the situation, such as how the property was acquired and whether there are any agreements in place between the couple. It is important for couples to have clear agreements in place to avoid any disputes in the event of a separation or divorce.
Each situation is unique and must be individually evaluated. If a couple owns a business together, that business would need to be appraised to determine its value. From there, the couple must decide whether they are capable of continuing the business together or if one would retain ownership and pay the other his or her equal share.
