2 DS now 25 & 23.
DS1 is living away from home in rented accomodation with a lovely girlfriend and a good job.
DS2 is a bit of a failure to launch situation, caused in part (IMO) by lockdown coming for him in the transition period between childhood and adulthood, and his father's traumatic illness and death also falling in that period. So DS2 still lives with me. He's a reasonably functioning adult at home, happy to help with chores and diy etc, works regularly in a minimum wage job, but hardly ever leaves the house except for work. Very very introverted. He always was but has gone right inside himself since his Dad's death.
If I die, they do well financially with a very significant sum each. To realise that, the house will need to be sold.
I don't want things set up so DS2 can stay indefinitely because DS1 is entitled to want his inheritance, but I also want to know DS2 has time, and support if possible, to find something suitable. He'll have the money, once the house is sold, it's dealing with the practicalities that worries me.
