My PILs have a difficult relationship. Despite being 'separated', they spend most days in each others company. MIL however, wants to divorce. The house is much too large for her to cope with, and is in a state of significant disrepair. FIL is happy for the status quo to remain, but if MIL seeks to sell the house (which she is desperate to do), he wants what he feels is his entitlement, which is half the house. This means she is effectively being barred from selling, as she would not realise enough from half the proceeds of the sale to buy a suitable house.
FIL moved out for about 12 months in the 1980s, and MIL got court ordered maintenance for the children (so it was an 'official' separation?). Upon his return he moved into the spare room. They never again shared a bedroom, and he moved out permanently in 1999. They have never divorced.
FIL subsequently purchased his own house, which he now owns outright. He retired 6 years ago, and since then he spends every day at 'MIL's' house, to which she gave him a key.
The MIL's house is still in both their names. They each have a pension fund, of which FIL's is far greater. It seems when they have discussed the matter that he thinks he is entitled half the value of the house, but is flabbergasted at the idea that MIL may have some entitlement to any of his pension assets.
I would be so grateful if anyone here could advise what their current entitlement to these assets might be i.e. FIL's house, MIL's house, and their respective pensions.
