Hi Victoria. Are you in an IVA ? If so, an inheritance, if over £500, is considered a windfall and, as such, is payable into your IVA. The IVA will continue as normal unless the monies paid in cover 100% of the original debt, plus fees and possible statutory interest, at which point it would end early.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
IVA Completed 23rd July 2013 .... C.C. 10th January 2014
