I don't exactly see that I've been avoiding a legal commitment.
You haven't married. That's not a judgement, it's just a fact. You have the option to make the legal commitment of marriage, you choose not to. The law will not bind you to a contract you did not enter.
Look the point I'm trying to make is that I'm frustrated that we can clearly show our long term commitment together but it's worth less than a couple who got married after, what? A couple of weeks together?
Yes. They chose to legalise their relationship. You haven't. You don't enter contracts by stealth. You enter them when you choose to enter them. And the law will not bind you to them until you choose to enter them.
Saying to everyone oh we're signing this contract cos one of us might die tomorrow so we won't invite you - but we'll renew vows or something in the future and you can all come to that sounds just rather mercenary, hardly romantic (and I'm not a romantic person!) and not exactly what we thought of.
Marriage is not romantic. It is not, nor has ever been, a contract of love. The idea that it is is an extremely recent concept. And wrong.
You can reject marriage if you think it 'sounds mercenary', but don't expect the law to change on that basis.
I'm also annoyed as said above that I/we have had paid for various financial advice over the years and this has never come up.
I'm surprised. Or did you make it clear from the start that you weren't interested so they didn't want to make it sound as though they were pressuring you? On this thread, as with every thread on this topic, there are posters who, when they hear the facts about marriage, accuse people of being 'smug' or 'trying to force people to marry' and all sorts of other assorted bollocks.
Excuse me, I have to go look up cheap bloody weddings now.
I think one poster did it for under £200. It's not expensive. Congratulations! Make the day whatever you want. Wear jeans. Go for Chinese afterwards.
