The house was purchased for £247k and we owe about £219k. I have a letter we used back when we purchased that we used money from our joint savings to pay for the deposit. We than supplied bank statements to show the money was built up from us and that we agreed the money used was a 50 50 split from what we had put in and that the 50% used from my partners side was a gift.
Hope this helps.
Split down it was £12,350 each
