This article will report on the different methodological, ethical and epistomological issues that were encountered in the context of a qualitative and comprehensive research carried out with lesbian, bisexual and queer non-birthing mothers who live in different context of social and legal recognition, namely in Québec, France and Switzerland (SSHRC, 2018-2020). The main objective of this article is to problematize the notion of positionality of the research. Being a lesbian mother who didn’t give birth to her child, the author of this article will address the problem of speaking for/about, as well as highlighting the relations of domination within the academic world by reflecting the practices and reflections related to the caption of speech by researchers in a privileged position, but also sharing certain social locations with their participants such as non-normative sexuality. These critical reflections will be carried out by addressing in particular methodological and ethical issues related to recruitment of LGBTQ+ parents by a person/researcher who identifies with these communities. The rich heritage of feminist and intersectional epistemology will also be discussed since it conceives the production of situated knowledge as a tool engaged in the transformation of the living conditions of the people concerned while contesting the production of dominant knowledge within the academic community which still claims, in some cases, a form of neutrality and objectivity.
