Treoir, the national specialist information service for unmarried parents, welcomes the commencement of significant sections of the Children and Family Relationships Act 2015 today, Monday 18th January. Unmarried fathers will for the first time in Ireland become automatic guardians of their child but only when they have lived with the mother of their child for a period of one year, three months of which must be following the birth of the child. This is not retrospective.
