Who owns the property ?
If she has an interest in it, there is a
possibility that this could count as ' capital ' which could cancel out any
housing benefit, or reduce it, depending on the sums involved.
It used to be the case that there was an exemption for a limited time if
the property was on the market for sale. I don't know whether this still
applies, my
benefits are getting a little
rusty.
Could be that she hasn't declared it. If she gets a
significant sum out of the financial proceedings, this could affect her
benefits as well.
