Hello, My sister's ex is claiming she is abusing her son and he is now taking it further as my sister has stopped her ex-mother-in-law from seeing her son due to issues between my sister and the ex-mother-in-law. Her ex is claiming he has photos to show bruises and scratches that she has left on her son's body and text messages between them and his mother proving that she smacks their son and uses a wooden spoon. Firstly, my sister does not abuse her son; if he is naughty she will smack him from time to time but that is it. There have been bruises and scratches on him (as he is a regular 3 year old boy who plays rough) but nothing to indicate he is being physically abused or domestic violence. Is there a chance my sister's ex has a child protection case against her even though these allegations are false? What would he need as proof for this matter to be escalated?
