Defended divorces are very rare, as reputable solicitors generally advise against them and the court doesn't want to force people to stay together.
This doesn't mean that your husband/the respondent will take their advice.
So I think we need to be clear about what can actually happen.
It is not possible to simply deny a divorce application or ignore it.
If a party doesn't want to get divorced they must provide the court with a formal response and use a specific procedure.
It is not enough to simply say I do not agree or ignore the application (although many do) but there are ways around this.
What Respondents can do is be difficult and prolong the process.
And it sounds like this may be what your husband is doing.
On the plus side when people realise the effort and money involved in defending a divorce application they generally change tact.
People say silly things when they are upset and angry and in the heat of the moment. They will try and influence you and scare you.
I know its hard but try not to let him rile you, you can not control his actions but you can control your response, and you DO have legal options if he doesn't comply.
Let his solicitors do the work, which he will be paying for and explain what his REAL options are and the likely costs that he will incur.
He might shop around for advice that suits his needs.
But the court requires a response within 7 days (allow working days) and this factor does not change and even disreputable solicitors have to work within the rules of the court.
It feels counter intuitive but perhaps give him a bit a time, he will eventually realise what his real options are, and if he doesn't there are options that are available to you to progress the matter.
Hope this helps.
