honeydo You said: both my brother and I thought there was more money. I thought she had as much money in the bank as the house was worth ( or close). That way, I would have had the money and my brother the house. All settled. That was what I expected. But it isn't there anymore.
I had not realised, as things are now coming out of the woodwork, that she bought my brother a new car ( I mean new) about a year or so ago and that’s taken a fair chunk. She bought herself a car before that and gave my brother a loan of some kind I am gleaning too ( nothing in writing). He never paid her any rent. I do know. Then there was the house extension for him to have a bed and sitting room area at one end of the house That certainly must have cost. It was to add value to the house I thought.
This changes things substantially.
A lot of money is unaccounted for. It will be necessary to go through your mother’s bank statements to find out what has happened and to identify, for IHT purposes, gifts made within the last seven years of her life. That will include the car bought for your brother. The money loaned to your brother also forms part of the estate because your mother was entitled to repayment of it, albeit on unknown terms. This means involving a solicitor is vital so that the true value of the estate, including gifts notionally added back into it either in full or in part through taper relief, can be ascertained in order to calculate IHT.
If this isn’t done, then when you apply for LoA, you will make a false declaration as to the size of your mother's estate and potentially be guilty of tax evasion.
If there is IHT liability after add backs, without resource to other funds, the house would have to be sold to pay the tax.
