Gay men and lesbian women have a long history of jointly creating families and co‐parenting their children together. This qualitative study aims to explore the experiences of separation and post‐separation parenting within same‐sex parented families. This involved semi‐structured in‐depth interviews with 22 separated same‐sex parents in Adelaide, Melbourne, Sydney, Brisbane, and regional Victoria. An adaptive theory approach was used for the collection and analysis of the data. The paper explores data from a cohort of six participants who came from three different multi‐parent families who had experienced a separation – either their own, or that of other parents in their parenting group. The term ‘co‐parenting families’ was found to be confusing due to the different connotations within separation/divorce and same‐sex parent literature. Consequently, the term ‘guild parented families’ was created to describe these families. Participants from these multi‐parent families had very different experiences of family formation and separation compared to others within the wider separated same‐sex parent study. Separation of one or more of the parent couples within these families complicated their original plans and kinship ideals. Each of the families resolved this differently in their post‐separation arrangements. After separation, whole family narratives and/or the role of individual parents, were either questioned or revised as a way of resolving the complexity of their new kinship situation. Following separation, parents often relied on Western kinship norms that privilege biological kinship and the dual‐parent family to construct their post‐separation kinship arrangements. More awareness of families that begin with more than two parents is needed within separation research and amongst separation services and service providers.
