no... Like I said... You maybe get divorced next year, so every year you have prove your together legitimately... This could involve multiple visits, photographs of your clothes in the wardrobe etc...
Like multiple people have said now, retirement is the way to go if you can. I've been married for 19 years and took the advice 7 years ago... Every the extension is easy..
retirement is the way to go if you have the 800k to put in a bank or the equivalent income.... Marriage is big hassle, but only 400k required in the bank.
