Inheritance nightmare - charge against the house

[DoneOver]

My step dad has died. His will leaves me and my siblings my mum's house. (She died first, house nothing to do with him.) However we have now found out that a while back he put a charge against it which gives most of the house value to his own daughter. (not my mums child.) Clearly mum stuffed up by dying before she wrote her will. But its very unfair, is there any legal redress at all?

Sorry just seen the ex wife has no say and the daughters too young. So just SD. What a horrible way to remember him.

From reading your update I see that the house is in a trust now - but not the one you were expecting (or that we were hoping to hear). Sorry - it's not always about the money at times like this, it's the feeling of being left out. Something similar happened to my mum and she was always resentful of it tbh.

In the longer term, I hope the house appreciates in value while it is in the trust and surpasses the charge against it to give you and your siblings a legacy closer to what your mum intended
