Mothers Rights

[trezmiffed]

My friend & her partner decided to split 4 months ago, & because the tennancey is in his name he said she could stay there till the council gave her a home for her & the kids. Last week however his family turned up & kicked her out & they wouldnt let her take the 2 children with her. After ringing the police they said due to the late hour to leave the kids there for the night, which she did. Since then shes been to visit the kids daily & wants to bring the kids home to her sisters with her, has she got the right to take the kids with her. There are no other agencies involved with this matter. We just want to know what her legal rights are as the mother.
