This project examines a new form of parenthood emerging in contemporary society: contractual co-parenting. This is a type of agreement in which two individuals agree to conceive and raise a child jointly without maintaining an affective or romantic relationship. Although increasingly common, contractual co-parenting remains unregulated in our legal system, raising questions about its legal validity and ethical implications, particularly with regard to the child’s best interests.

This study first identifies the defining features of this model, distinguishing it from other forms of parenthood, and analyses it from an interdisciplinary perspective that includes law, ethics, psychology, and sociology. The project also considers how other countries regulate similar arrangements, the role of co-parenting agencies, and the risks of commodifying parenthood. Its ultimate goal is to contribute to the development of policies that protect the rights of minors and provide a coherent legal framework for this emerging social practice.
