Bigamy

A legal or de facto separation of the couple does not alter their marital status as married persons. In the case of a person in the process of divorcing their spouse, that person is taken to be legally married until such time as the divorce becomes final or absolute under the law of the relevant jurisdiction. Bigamy laws do not apply to couples in a de facto or cohabitation relationship, or that enter such relationships when one is legally married. If the prior marriage is for any reason void, the couple is not married, and hence each party is free to marry another without falling foul of the bigamy laws.

Bigamy is a crime in most countries that recognise only monogamous marriages. When it occurs in this context often neither the first nor second spouse is aware of the other. In countries that have bigamy laws, with a few exceptions (such as Egypt and Iran), consent from a prior spouse makes no difference to the legality of the second marriage, which is usually considered void.

Even before Christianity became the official religion of the Roman Empire, Diocletian and Maximian passed strict anti-polygamy laws in 285 AD that mandated monogamy as the only form of legal marital relationship, as had traditionally been the case in classical Greece and Rome.^{[citation needed]} In 393, the Roman Emperor Theodosius I issued an imperial edict to extend the ban on polygamy to Jewish communities. In 1000, Rabbi Gershom ben Judah ruled polygamy inadmissible within Ashkenazi Jewish communities living in a Christian environment.

 

Most western countries do not recognise polygamous marriages, and consider bigamy a crime. Several countries also prohibit people from living a polygamous lifestyle. This is the case with the United States where the criminalisation of a polygamous lifestyle originated as anti-Mormon laws, although they are rarely enforced. De facto polygamy is illegal under US federal law, the Edmunds Act.

In diplomatic law, consular spouses from polygamous countries are sometimes exempt from a general prohibition on polygamy in host countries. In some such countries, only one spouse of a polygamous diplomat may be accredited, however.

• China: Illegal. Up to two years' imprisonment, and up to three years for bigamy with soldiers (but tolerated for some minorities, such as Tibetans, in some rural areas in the south-west).^{[citation needed]}
• Colombia: Illegal with exceptions (such as religion). Although bigamy no longer exists as a lone figure in the Colombian judicial code, marrying someone new without dissolving an earlier marriage may yield to other felonies such as civil status forgery or suppression of information.
• Egypt: Legal for men if first wife consents.
• Eritrea: Illegal. Up to five years' imprisonment.
• Germany: Illegal. Up to three years' imprisonment.

• Republic of Ireland: A criminal offence under section 57 of the Offences Against the Person Act 1861, up to seven years' imprisonment. The Director of Public Prosecutions has discretion and rarely prosecutes. Catholic canon law permits a second marriage if the first was in a UK register office or annulled by the church; the state considered such marriages bigamous without a civil annulment (more restricted than a church annulment) or divorce (illegal from 1937 until 1996) and two cases in the 1960s led to suspended sentences. The 1861 act replaced an 1829 act which in turn replaced acts of 1725 and 1635.
