The fact that you may be charged with assault or something else is not relevant to a financial settlement.
You have to sign a statement of truth on your financial declaration and to lie on it is perjury.
You have to do supply all the information they have asked for and your ex-wife has to do the same to you.
Is likely that you would be charged with section 39,, assault and receive a fine or community service if found guilty. There doesn’t have to be any physical contact. A person just has to fear immediate physical violence.
Can I clarify anything for you?
