Thank you for your question
My name is Clare
I shall do my best to help you but I need some further informtaion first
What ground is the divorce based on?
Did he file an Acknowledgement of Service?
Just to check - you understand that a phone call costs more?
I ask because his chances of doing this are very slender anyway
In order to oppose the Decree Nisi tomorrow your ex would have to make a verbal applictaion to file an answer out of time, produce a written answer, and pay the fee
Unless he is able to do all of this then the Decree Nisi will be granted.
In addition the Divorce has no link to Child Contact
Please ask if you need further details
