Very interesting information, and just to share bit to this discussion. There is no objective definition of marriage, save for a few things – and even the gender of those involved is technically variable across numerous cultures. That being said, the sole objective definition of what constitutes a marriage is a partnership between two people, financial and otherwise. Couples must hash out the details of the finances before any papers are signed, including overall goals like retirement, a college fund for potential offspring – all aspects of financial planning. There must be a plan, on everything from how to set up accounts, when to use credit cards or get a cash advance if need be.
