Separated from wife 2014, she remained in house. In 2016 we agreed split of house sale (she bought with new partner). She received £75000 I got 29000. However now going through divorce and on consent order she is showing as only having 37500. She says her solicitor has said it is correct as she now owns house with new partner so her original amount is now halved. On paper it looks like she only received 37500 when infant she got 75000. Can this be correct.
