Short history: DM died in 2010, DF (64) got with his partner within three months of her passing. DF owns his house, his partner sold her house and lives with him rent-free. They've been living together for nearly 4 years. My sister and I are very concerned that he has no plan in place in the event of his death.
We're pretty certain his property would automatically go to us, as he and partner are unmarried but surely if she's been living there all this time she may have some claim over it?
Sister has tried to ask dad (gently) to make a will but he just gets very quiet and withdrawn, it is v in line with his behaviour since DM's death to not want to rock the boat and to bury his head in the sand.
But is it time to ask a little less gently? If he wants to leave his partner something that's his choice and I'd respect it, but all I can see is an ugly mess having to be unpicked, with his partner's v interfering family all sticking their noses in.
