Jalima1108, you say that joint tenancy is not that usual. I don't know how 'usual' it is, but there are two options and joint tenancy is one. It's the option that we chose. The first survivor inherits the title 100% - that's how we wanted it. Actually I suppose there is a third option - the old-fashioned one where the title was in the man's name only assuming him to be the 'breadwinner'.
We have 'mirror wills' but there are one or two differences. We each have a legacy to a named charity of our own choice. Mine is to a wildlife hospital, his is to the local air ambulance. We've also left clear instructions in our wills as to where we want to be buried - a 'green burial ground', its name and contact details.
The last funeral we went to, we were asked to wear pink because that had been her favourite colour. I've let everyone know that I don't care if you wear pink, blue, green or any other colour/s, but please, no black. And snowdrops to be planted on my grave.
