Yes, this thread is old, and I have read the comments on the newer thread too. I have to say, Wikivorce has been a useful site, with some good advice, but I disagree totally that the issues with Brethertons were limited to 2013/14 or to a small number of clients.
I really wish I had never used Brethertons. They hide behind the "we may take up to 10 days to deal with your query" meaning literally every email takes at least 10 working days (2 weeks) for any kind of reply - even the simplest reply.
The worst thing though was the drafting of the Consent Order. Our agreement was pretty straightforward, and I had more or less drafted it. It took the usual weeks and weeks to get it signed by me, (two weeks to send to me, one day to send back, two weeks to send to my husband one day to send back, two weeks to acknowledge receipt, two weeks to send to the court . . you get the picture). They warned me there would be a delay of up to 10 weeks at that point. After 12 weeks I emailed for an update. They had of course received the papers from the court three weeks earlier - when would I know had I not emailed? Worst of all was that the judge had said that whole sections were "meaningless and completely unenforceable". I would at least have assumed that I was paying for and getting a document drafted in a legally acceptable way. I am now back to the 2-weeks to redraft, 2 weeks to email to me, 2 weeks from me saying "fine" for them to send me the written copy to sign (I signed and returned in one day), two weeks before they sent it to my husband to sign, and now I'm waiting for them to tell me when they might possibly send it back to the court.
They have been utterly hopeless and I wish I had splashed more cash at the beginning and gone with a firm that were professional, customer-centred and knew how to draft a legal document. Caveat emptor.
