Thank you for your question
My name is ***** ***** I shall do my best to help you
I am afraid that the new documentation will need your name on it at the time that it is sent to your partner's ex.
However if he refuses to sign the application then your partner can apply to the Court for the Judge to sign the paperwork instead
I hope that this is of assistance - please ask if you need further details
It is a matter of applying to the same Court on a D11 - the fee is £95
