Heterosexual couples now have an alternative to marriage. As of January 1, 2020, heterosexual couples can now enter into domestic partnerships.
Prior to the new law going into effect, only same-sex couples and heterosexual couples over the age of 62 could enter into a domestic partnership. Since 2013 same-sex couples have been allowed the choice of either entering into a domestic partnership or entering into a marriage, but now domestic partnership is generally available to anyone who wishes to enter into one.
There are, however, still certain individuals who do not qualify to enter into a domestic partnership. This includes anyone under 18, people who are already married, people who are not legally allowed to marry, such as certain individuals related by blood, and those who are not capable of consenting to a domestic partnership.
