Welcome to Wiki!
I'm sorry you've found yourself in this
all-too-familiar situation.
Quite often the person who wants a
divorce (rarely do both parties agree about it) has very clear ideas about
what the other person is entitled to. But their ideas are usually way off
the mark.
Firstly in any divorce the priority is the children,
if there are any. It's usually best to maintain the status quo for them,
so if one parent is the main carer, they usually get
residency. If both
parents care equally, joint
residency is quite
normal too.
As for the finances - both people need to live. If
joint residency is decided, then both parents need housing adequate for
this. If one parent gets residency then the non-resident parent needs a
place big enough for the children to stay overnight.
Finances
are decided according to need, not according to who paid most or who was
unfaithful. All assets of the marriage whether jointly or separately owned
are up for splitting between both parties.
It's best if parents
can agree about finances and childcare, perhaps with
mediation if they can't do it between
themselves. If it goes to court it gets nastier and usually neither party
gets what they want, there's less money because it goes on legal costs.
Perhaps if you let your wife know this she might be more
co-operative.
Has she told you why she wants a divorce?
Perhaps she thought she'd be better off, so you might want to tell her that
usually after divorce both parties have to downsize.
