Accept that your daughter can stay with you and reduce
child maintenance and/or
spousal maintenance accordingly. Make it clear before arrangements start
that you will be doing this and it might get her to rethink.
If
you do need to work away then your daughter can stay with mum during that
time? Or as suggested with grandparents?
Can daughter share
with sibling for short term while renovations take place?? Or with mum if
sibling is male? Or mum can take the sofa for a few months!
Her
housing needs surely would have been taken in to account during the
financial proceedings so how she houses herself and the kids should have
been settled.
By the sounds of things you need to do all you
can to make it third time lucky!!
