I have avoided posting on this subject before because I didn't want to distress anyone undergoing separation due to dv; but there has been a massive legal sea change on the rights of contact for non resident parents.
A new child arrangements order came out in April last year which superceeded all previous contact / PR orders. Basically this order gave far more powers to non resident parents (usually fathers). Under this legislation there is essentially no powers to deny non resident parents the rights to see and have as far as much is possible equal access to their children.
Domestic violence is not a reason to restrict contact. It is not classed as a failure of parenting. As long as the parent seeking access did not physically harm their child, they will be granted contact as the domestic violence was only being directed at the other parent - it doesn't matter if the dv occurred in front of the child.
Nor is the scenario of an absent father suddenly deciding to come back into their child's life. Contact will be granted as much as possible to grant 50:50 contact known as shared care.
I presume the rationale of the act was to support the right of non resident dads to have the right of equal access to their child without their mothers raising pesky accusations of domestic violence to deny access to their children.
I have been through domestic violence - it was pretty horrendous and I genuinely feared for my life - refuge, police involvement, social servicws , IDVA teams etc. I was a single patent caring for my baby with little involvement (except control) from ex. Despite this my ex took me to court last year and was granted almost equal contact and 100% aqua
Residence during holidays. In court, I was essentially put on trial. My ex excused his violence and control on the grounds of self defense, accidentally hitting me or breaking my possessions and his control on the grounds i was a very passive person who had a mental illness which required someone to paternally control me for my own good.
During this court process he sought to get even more than 50% residence. I managed to fight him for this but it was very difficult - my son has autism and even this was not a good enough reason to radically change the pattern of contact he was used to.
The whole court process cost me 14 k - I had to borrow it from family. It was a horrible process and the new law changes have not IMHO been well publicized at all
