Who is the legal guardian of a child when parents have separated
My boyfriend has 2 daughters to his ex partner, they were never married but he is named on their birth certificates and has them to stay with us every week. His ex claims she is their legal guardian and regularly prevents him seeing his children because she says she has the power to do so as their legal guardian. The children do live with her but it has never been to court, what rights does my boyfriend have to his children they were born in 2004 and 2005.
