If your circumstances change you have the right to apply for a
variation.
The Court always has power to award a lump sum in
lieu of spousal maintenance, but the issue, of course, is whether the payer
can afford such a payment.
I would say it is possible you might
be expected to make payments out of your lump sum for a time ; but not for
very long, I think. You wouldn't be expected to exhaust it altogether.
Unless your unemployment is likely to be permanent, it seems to me
appropriate that you should only pay at a nominal level, say 5p per year,
which can be increased to a more realistic figure when you get a job.
If you can, try and negotiate this with your ex. If it makes no
difference to her there is no reason why she should object. I
would advise you get your agreement incorporated in a
consent order, to be safe.
Unfortunately for
you, the fact that she is on
benefits doesn't affect the
position. That's the whole purpose - to save money for the Treasury.
