Can anyone offer any advice on a potential property dispute, please?
FIL has been married to SMIL for around 35 years; second marriage - 2 children from first marriage and one from second, all grown up. Age difference of 24 years is relevant.
SMIL and DD are originally foreign nationals and did not move to the Uk until DD had finished school in their home country - DD came first and SMIL followed a few years later.
During the marriage FIL bought a house in the UK in his sole name, paid the mortgage and house is now fully owned. When SMIL moved here I think there were maybe a few years left on mortgage but she didn't contribute and does not contribute to household bills, just her own expenses (food and broadband).
During the marriage SMIL bought a house in her home country in her sole name; she did work but also received generous support from FIL.
SMIL home is now probably worthless and she is unable to return so is disregarded.
FIL's will stipulates the house to be sold on his death and the estate divided equally between SMIL and the three children; his thinking behind this is because of the age gap he would effectively be disinheriting his children from first marriage if he left house to SMIL. Apparently SMIL was unaware of this and assumed she would inherit on his death.
FIL is elderly and in early stages of dementia and has also suffered several TIAs and a stroke. FIL has now received a letter from Land Reg applying to transfer half the house in to her name. He does not wish to do this, but still lives with her and the situation is uncomfortable for him.
Can anyone advise on where he stands? Does his DW's claim on the house trump FIL's wishes (his will was properly written by his solicitor, it's not a self-written one)?
Sorry it's so long, and thanks for your help 🙏🏻
