Inheritance/will - your suggestions please.

I'll try and keep this simple, your suggestions greatly appreciated.

Person A has 1 child with person B. Works full time, earns around £50k.

Person B has 1 child with person A, also has 2 children from previous marriage. Works full time (apprenticeship) earning around £20k and recieves maintenance for older 2 kids from ExH.

Person A and Person B are a married couple, both on mortgage and documentation already in place due to previous contributions to the marital home mean person B has 75% share of home, person A 25%.

It's time to make wills. Person B is happy to split everything 3 ways between the 3 kids and give person A lifetime tenancy in the home etc.

Person A is wanting to make sure child (AB) gets their fair share of inheritance.

Is there a simple way of sorting this?
We've got a solicitor appointment but would like to have a clear idea beforehand.

I would do 50% to AB and 25% to the other 2. And if you wanted to review it in the future if the assets accrued had a different composition then A leaves her share to AB and B's share is split in 3.

A has 1 child. All of their half goes to that child.
B has 3 kids. Each child gets a third of their half (a sixth of the total).
So, the shared child gets 4/6, the other kids 1/6 each. Plus a potential share from their other parent.

Yes agree, this is the fastest way

But person B with three kids has paid for 75% of the home, and person A with just the shared child has paid for 25%.

In this situation, it seems that B's older two kids would lose out on the majority of money their parent invested in the house if they end up with just 1/6.

Parent B’s kids get a third each of 75% of the house
Parent A’s child gets 100% of 25% of the house

I guess it depends on house price.
400k house would mean the lower earning partner contributed 200k more. With a 30k differential in salary, that would be eroded pretty quickly in terms of money into the family pot.

Child A gets Dads 25% of the house

Child B gets 45% off mum

Child C gets 45% off mum

Child A gets 10% off mum

overall child A gets more because mum and step father both give them money.

Child B& C might inherit from their father

another way to do it is

give 33.3 each of your share to A, B & C

yes A will get more overall

Because the person with the most children has put most into the house - more or less proprtionate to the number of children - I would keep things simple and split it all 3 ways.
