The Rainbow Community Kampuchea (; RoCK), with the help of local authorities, has created a formal relationship registry program, called the "Declaration of Family Relationship". According to RoCK, "the Declaration of Family Relationship is a civil contract between two people who are willing to be together and share responsibility taking care of the family, children and distribute the joint asset, as legal spouses do". By May 2018, the civil contract had been introduced to 50 communes in 15 provinces, and 21 couples had signed the forms.
