Is this inheritance set up unreasonable?

Couple have been together 8 years.

Thinking of buying a house together/getting married. Blended family and need to have the wills discussion before financial entanglement.

Person A. 2 kids from previous relationship. One is disabled meaning they can’t really work anymore now a full time carer. Kids primary age.

Person B. 2 children from previous relationship now teenagers. Well paid job.

One shared child.

Person A owns a property and will rent it out for some income but it’s pennies compared to person B salary.

The new house will be both on the deeds and eventually spilt evenly between all children in the wills.

Other parent of children B also a high earner and has no other children. While we cannot know how that will go it’s likely children B will inherit well from both parents. Children A will get nothing from their other parent.

The question is about person A property and inheritance likely to come from grandparents.

Person B thinks the rental and both sets of inheritance should be split equally between all children in the wills. Person A would likely use inheritance to get a second rental and the rent would be joint money but once A is dead both rentals divide by 3 children (2 previous and shared child).

I’d like some outside perspective without having to talk money with friends and family.

I think it is fair because children B will also have inheritance from their father.

current/new house: splits into 2 (person A and person B) who would then each split that three ways with a share going to a each of their respective children. Shared child gets 2 shares

Existing rental property I would split between person As three children

a new property that is bought after financial entanglement, so any property you may buy with an inheritance, I would split as per the new house you are buying. Person A is being financially supported by person B so it seems fair any assets they accumulate after that starts happening are joint.

However second rental property doesn’t exist yet so I would make the wills as above then reconsider if and when Person As parents die and you know what you’re working with.

I do think as a blended family ALL rhe children should be treated equally irrespective of any possible inheritance for their other parent. But if I were one of the grandparents in this situation I wouldn’t want my legacy to go to step-grandchildren unless I was particularly close to them.

Person B is unreasonable to think that person A should divide their assets (the rentals) between all 5 children (if i've understood that right).

I agree with @IceIceSlippyIce

A has three kids. B has three kids.
A shares their 50% between their 3, and B does the same. Yes, that means the shared child gets twice as much.

Yes. I agree with this. It’s the fairest way and easy to put into practice

Will the disabled child be able to work in future? If they are reliant on benefits then the inheritance would potentially stop them so they wouldn’t really benefit?

How does person A cover their current outgoings and kids costs?

Treating children fairly doesn’t mean treating them
the same. I think it should all be evenly split 50/50.
