Myisernameismud this is a fair point... obviously I don't know your back story, but in my case it was deemed unsuitable for mediation, based on the evidence I had of dv, along with a heap of ss evidence about how unstable mental) the father is.
It seems to me in my limited experience that it very much depends on the magistrates/judge on the day. The fdhr in my case, they granted the CAO, but were umming and ahhing about the PSO, and the surname change (said it was not obvious enough on the papers served to him, even though it was clearly stated, and when cafcass spoke to him, he clearly stated he wasn't interested).
The hearing was only stopped when an email came through from his father stating that he was unwell. Which was enough to stop proceedings on that occasion and actually I am glad about that, as then I was able to submit my statement, with all the evidence (all 35 pages of it) which led to everything that I had been asked for being granted. Again, as I said, I was lucky enough that the father is an utter lunatic and basically (and I don't think this was his intention, his intention was always be to try and make me out to be a monster, and that shone through in it that he didn't give a rats arse about his actual child, along with the supporting evidence from ss and the police) he put the final nail in his own coffin.
Actually, I wonder, and seeing as it is sat night, I can't email my solicitor, could anyone actually confirm whether or not he would have received a copy of the court orders that were made in his absence?
Anyhoo, upshot is, we are now protected from him, he can't take her from me or any other third party, I can take her on holiday for up to 28 days without his permission (I should be so bloody lucky!!) and her surname has been changed, to alleviate any negative connotations with his name or his family.... He forced me to give me his in the first place when I wanted to give her mine until we were married (yep, I was actually engaged to that waste of oxygen and we were due to get married the summer after she was born, dodged a great big massive bullet there!) and I could prove that.
Sorry this has turned out rather long. Basically, if you can state a case for whatever it is you want, then as you say, Myusernameismud, nobody wants to go through the stress of the courts in the first place, let alone again if it can be helped.
Again, those saying that court ordered changes of surname aren't granted, just because it will make life easier and less stressful and harmful for the mother and the child, I think my case bucks this trend. That's not meant to undermine anyone and their extensive experience, or give people false hope, but that is very much what happened in my case. I've said it about three or four times now, but it was the magistrates who suggested that by making his surname another middle name, and changing her surname to mine, that should satisfy any need to link to her father. Maybe I was just lucky that the people on the day saw sense. I don't know. But again, my own solicitor was quite surprised that it was granted, perhaps they had access to reports/information from ss that I was not allowed to, because, you know, data protection.
Anyway, that's just my experience.
