Yes. Registered domestic partners may dissolve their partnership. In 2008, the law used to divide property and debts was applied to domestic partners. In 2012, partners in a state registered domestic partnership were able to marry. Additionally, state-registered domestic partnerships in which neither person was 62 years or older, were automatically deemed a marriage as of June 30, 2014. The partnership is dissolved the same way a marriage is dissolved.
Domestic partners may also have a common law “equity relationship” that may be tagged onto the years of marriage, and the court may equitably distribute community property they acquired during that time.
