TLDR It’s not that simple with some folk!
I’m guessing you have straightforward arrangements.
I’m afraid you are mistaken about how very wealthy people like my in laws amass and hold onto assets and money, they do not care about what is right or what the law is, they usually consider themselves above it, a will cannot protect you from these sorts.
All it takes is one person to contest the will for whatever reason and you are in court potentially forever but in reality until the lawyers have stuffed their pockets with the majority of the estate and you are out of cash. It can go on for years.
Rich people with deep pockets have extremely clever and powerful barristers at their disposal whenever they really need or want it, in my husbands families case they use the same firm that the govt keeps on a retainer.
They are the most impressive sharks I have ever encountered. When one of them looked me dead in the eye I physically shuddered, I wasn’t looking at a human as I understand them, more like a terminator!
I would in comparison be able to afford the local numpties for a short time who look like they still buy their shirts in the school uniform section of the supermarket 😂
They understand you don’t have the resources and will be outgunned n battered into a corner where you agree a deal that suits them which they consider a good win, or they just keep going until they win regardless of the money because winning is as important as money to these types, the ego’s are immense, the law is a game to them.
To ensure anyone who marries into a wealthy family has as little of the assets as possible it’s standard practice to make sure the family have their name tangled up in everything. Just for example by way of a small money gift at the start of any new business venture or a change in direction or even simply buying a house.
It is marked on the accounts as a ‘loan‘ but it is not repaid because it was given as a gift - that bits not documented so if anything happens it’s easy to argue in court that they rightfully should have a percentage of the business or investment proportional to the size of the initial loan and the value of the business when it started. All they need is some clever dick to prove the business was only worth the same or less than the loan at the start and hey presto they are owed the majority of that asset.
They have other tactics and I could go on but basically it’s a minefield. It’s why rich people are always in court, they know the angles and have money.
Getting married was definitely a good idea on Mr SSOAPs part, I’m glad he grasped things so early on while I wandered about blissfully naive but I have now seen it happen with my own eyes twice!!
We have worked hard to legally disentangle ourselves from them but honestly that’s not easy and there’s never any certainty that it’s enough!
