The practice of informal polygamy within fundamentalist groups raises several legal questions. It has been considered difficult to prosecute polygamists for bigamy, largely because they are rarely officially married under state laws. Without evidence that the alleged perpetrators have multiple formal or customary marriages, these groups are only subject to laws against adultery or illegal cohabitation – laws that are not universally enforced because they also criminalize other behaviors that would otherwise be socially sanctioned. However, some „fundamentalist” polygamists marry girls before the age of consent or commit fraud in order to receive social assistance and other public support. This, in turn, raises the question: what realities prevail? Finally, some realities are mutually exclusive, such as Hoogland`s belief that his child is a girl and his ex-wife`s belief that the same child is a boy. Similarly, at some point in the future, a two-year-old boy`s desire to understand which of his three „parents” provided his genetic inheritance (i.e., which two of the three were his biological parents) could conflict with the legal recognition of three people as equal parents. On which side is the law in such cases, when everyone appears, will reveal the underlying moral hierarchies that are now solidifying. Lawyers for the provincial attorney general argued that the province`s children`s law does not allow more than two people to be named as the legal parents of a child. But a divorce would not solve other legal problems peculiar to polyamorous families. Canada is at the forefront of this quest for massive adaptation of reality.
Recently, for example, a Canadian judge ruled that the three adults in a polyamorous relationship should be legally registered as „parents” of a two-year-old boy they are raising as „throuples.” And last month, Vancouver postman Rob Hoogland was arrested for calling his biological child „she” — because his ex-wife and the school his child attended helped the child (known as A.B.) make the „social transition” to a masculine identity. The court prohibited Hoogland from referring to her as „they” or trying to influence her child in any way to get him arrested. He refused to comply and has now been imprisoned for contempt of court. The 5. In May 2011, long-term cohabitation between unmarried people, known as união estável („stable union”), was extended to same-sex couples, recognized as a family business and granted to all 112 rights of married couples – the only legal difference in marriage is that it does not change individual marital status from single to married.

Debates on the legalization of polygamous marriages continue in Central Asian countries. [Citation needed] „About 3 and a half years ago, we made the decision to open our wedding and we each have additional partners. I have a male partner who lives in England, and my husband has a female partner who lives here with us,” Ouellette told CBC News at his home in northern Alberta, „There`s a choice other than serial cheating or monogamy and multiple divorces or failed relationships.” „On the contrary, the applicants` refusal to recognise paternity (descent) would deprive the child of a legal paternal inheritance with all the rights and privileges associated with that designation.” When asked why he chose this line of research, Boyd says he became curious after a number of polyamorous clients asked him for legal help. In most countries, a person who marries one person while still legally married to another, bigamy, commits a crime, although penalties vary from jurisdiction to jurisdiction. In addition, the second and subsequent marriages are considered legally null and void. Some sects that practice or at least sanction polygamy are the Fundamentalist Church of Jesus Christ of Latter-day Saints (FLDS), the Church of Latter-day Christ, and the United Apostolic Brothers.
Polygamy among these groups now exists in Utah, Arizona, Colorado, Canada and some neighboring states, as well as up to 15,000 isolated people without organized church membership.  The polygamous churches behind Latter-day Saints are often referred to as „Mormon fundamentalists”; However, the main church of the Church of Jesus Christ has rejected polygamy since the beginning of the 20th century. Mormon fundamentalists often use an ambiguous revelation of September 27, 1886 to John Taylor as a basis for continuing the practice of plural marriage.  [untrusted source?] The Mormon practice of plural marriage was officially established on July 12, 1843, by Joseph Smith, founder of the Latter-day Saint Movement. Because polygamy was illegal in the state of Illinois, it was practiced in secret during Smith`s lifetime. During the Nauvoo era from 1839 to 1844, when several Mormon leaders (including Smith, Brigham Young, and Heber C. Kimball) took on several wives, all Mormon leaders who publicly taught polygamous doctrine were disciplined. For example, Hyram Brown was excommunicated on February 1, 1844.  In May 1844, Smith declared, „What a question for a man to be accused of adultery and to have seven wives, if I can only find one.”  Polygamy is a crime that, under the law of each state and the circumstances of the crime, can be punished by a fine, imprisonment, or both.  Polygamy was banned in federal territories by the Edmunds Act, and there are anti-practice laws in all 50 states, as well as in the District of Columbia, Guam and Puerto Rico.  Since state laws exist, polygamy is not actively pursued at the federal level, but the practice is considered „against public order” and, therefore, against the United States.
The government does not recognize bigamous marriages for immigration purposes (i.e., it would not allow one spouse to apply for immigration benefits for the other), even if they are legal in the country where the bigamous marriage was celebrated.  Any immigrant who comes to the United States to practice polygamy is prohibited.  This judgment alone shows that there is some recognition of polyamorous relationships; However, there is still a long way to go. If you have family law issues and are in a polyamorous relationship, you move into a new area of law. This means that you need to make sure that you fully understand your legal options in all cases. In 1953, the state of Arizona studied and invaded a group of 385 people in the polygamous colony of Hildale and Colorado City, which stretched across the border between Utah and Arizona. All the men were arrested and the children placed with foster families. A judge eventually declared the action illegal and all returned to the community, which now numbers about 10,000 people.  Without the protection of marriage, polyamorists face a long struggle over family law. Only one third of those who participated in the survey said they had taken the necessary steps to formalize the duties and rights of all members of the family unit. Even then, there is a limit to what these steps can accomplish.
After Joseph Smith`s death, the practice of polygamy continued in The Church of Jesus Christ of Latter-day Saints (Latter-day Saints Church), then led by Brigham Young.
