This isnt me BTW.
Self employed, claims UC, single parent, mortgage. Gifted sone money from family member to pay a chunk of mortgage off. Didn't pay it off but left it in savings, didn't declare it. Didnt spend it. Worried about COL crisis, car going wrong etc. Continued to claim UC. Has since paid money off mortgage.
Currently under investigation , provided all bank statements which show the amount sitting in the savings account.
What's likely to happen? Repay UC and a fine? Court?
