The term cuckolding, or cohabitation, refers to the arrangement of two or more adults living together in a committed relationship, which usually lasts a few years.
Although it may sound unusual, it is often practiced in marriages that are monogamous.
The first known documented case of a couple living together as married was in a Dutch court in 1642.
This marriage was the first to have legal recognition in the Netherlands and was also the first time couples had been legally married.
Today, there are more than 200 countries where married couples can cohabit or live together without legal recognition.
Many couples have different definitions of cuckolds and different definitions for what constitutes marriage.
However, the majority of marriages have a single definition of cuckservative marriage: The couple share the same legal rights, such as the right to inheritance and property.
However a handful of countries, such a the United States, allow unmarried couples to marry.
In the United Kingdom, unmarried couples can marry under certain conditions such as if they are a childless couple or if they live together as a couple and one partner dies.
In France, couples can only legally marry if they have been married for at least a year.
In Australia, it may be legal to marry, but the legal age to marry is 16.
