Hi Mary
As stated in your previous post
www.benefitsandwork.co.uk/kunena/10-dla-...e-repossessed#306854 your question is outside the remit of the forum.
I have not known DWP to reposes homes, but you will be hit with an overpayment and they may charge you with fraud, so you do need to seek specialist advice where they can take all your circumstances into consideration.
