Who is right? Long term partners but not married

[springisnotsofaraway]

A lovely family I know, they have two kids, together since they are 18, (so more than half their life).
She wants to get married, he doesn't (or let's say, isn't bothered in the slightest).
For some reason this came up in a conversation me and a friend were having and my friend said there's got to be something wrong as they are not married, it's odd that they have house, kids, etc but never married and that if it's right, the bloke always wants to get married.

Do you think this is true?? I don't think so but she was adamant that if all is well and the guy 1000% committed, you'd get married.

Now pensions are soon to be also coming under inheritance tax, most reasonable earners who own a property will be getting close to/over that limit in their 50s/60s.

Just looked up and the median net worth for 55-65 year olds is £495K according to the ONS (counting pensions, property equity, investments and cash).

Kids of those people will be hit effectively twice over with IHT.

Like I said, if married, you have more financial protections. That’s what I am saying..
