Change the laws on mothers who deny fathers the rights to see there children

Background

I wish to start a petition for fathers who are not seeing there children due to the child’s mother stopping them With out good reason or through a court order

Additional details

I believe that 1000s of men in the uk are suffering with mental health issues due to the mothers of there children laying the law down and stopping them see there children. Is it fair for loving fathers not to see there children because another parent has a grudge or is upset it is not just the father it’s effects it’s also has massive impacts on the children. #mensmentalhealth #fatherstogether
