Yes can make a difference. If your a dad you would avoid going down that path as it makes matters more complex. It would cause more delays trying to get contact with children and as a dad you wouldnt achieve anything at the end of it.
As a mum there could be a find a fact hearing. If there is evidence then there would be implications for dad seeing children if hearing did not go in his favor.
This could be a result meaning small implication to major ones as a consequence.
I think if a scotts schedule is asked for you list up to about a maximum of 10 things that have happened and there would need to be some evidence to back it up for it to stick. There are things like parenting courses/separated parenting programmes he could on if you decide or courts decide not to do a fact finding.
Sometimes a judge/magistrate can base his decision on how father represents himself and read relevant cafcass reports as well as background criminal record etc.
