Hello my name is XXXXX XXXXX I will help you with this. Please note that I am a working Solicitor and may be on and offline as I have to attend Court and meet with clients, even at weekends. As such you may not get an instant response when you reply, but rest assured I will be giving your question my immediate attention upon return You do not need to wait here as you will get an email when I reply.
Unless they object in France then yes this is ok.
There is no reason why a UK Solicitor can't witness it.
After all they are a professional and in the legal profession
Can I clarify anything for you about this today please?
Thank you that has put my mind at rest.
