It’s really complicated isn’t it? My parents divorced 30 years ago.
My mother has been with her partner for 27 years. They have one child together, my 2nd sister. My mother had two children, me & my first sister, with her first & only husband. My Mum told me that she & her partner have made wills. If they both pass before they need care, half the house will go to my 2nd sister, the other half will go to myself & my 1st sister, so 25% each. I think that’s fair, & at the end of the day, it doesn’t matter what I think as it’s not my money! I would rather my Mum spend the money herself as she has had a tough life & very little in financial terms other than her home.
I am not counting on any inheritance as nobody in my family thus far has ever inherited anything, as they didn’t own their homes. Additionally, it’s highly likely that my Mum or her partner may need care in the future, as both have had health problems, so I am certainly not banking on inheriting anything.
As far as my Father is concerned, my 1st sister & I are his only children. However, I don’t expect to inherit anything from him. His partner has never wanted anything to do with my 1st sister & I, & my father has gone along with this. Also, his partner has lent him significant sums of money over the years so I imagine she will be left his half of their home. My Fathers partner has no contact with her own children having abandoned them very early on in their lives. His partner has also inherited from her own parents, as an only child. I have no idea where that money will go but I am certain she will sooner leave it to a charity or stranger than allow my first sister & I to have anything. If, by some strange twist of fate, we were left anything, I would give some of the money to my 2nd sister, as she has no family on her Father’s side.
Where step-families are concerned it’s really complicated. As I said above, inheritance hasn’t really applied in my family up until now so it’s not something I’ve given much thought to. I think it very much depends on the partners of your parents, their attitude towards towards their step children, & your parents attitude towards their own children.
I see so many threads about inheritance & how so many people perceive it as a ‘given’ & are then very disappointed when something goes wrong. From what I’ve read, it seems the biological children are often the ones that lose out the most when new partners/husbands/wives are thrown into the mix. I think inheritance is a source of so much upset, it needs to be very carefully thought out & ideally discussed before death, where possible of course, to prevent any surprises.
