I have been with my partner for 12 years. We're very committed to one another, have a loving and trusting relationship, and are expecting our first baby in the autumn. We've always wanted children together, but never been fussed about getting married and don't plan to. This is a joint decision that we are both happy with. We have mirror wills.
Over the past few months I have seen so many posts on MN advising women not to have children with someone they aren't married to. Why is this? I don't mean this antagonistically or obtusely - I am genuinely curious. I have a good job that's well-paid (my partner earns more, but not by that much - although long-term his earning potential is higher), we have a house with a joint mortgage (50/50 deposit). Both own our own cars, have good pensions, and our respective (separate) savings. Granted, my partner's car is of higher value and he has more savings than me. I plan to take 12 months' mat leave and then return to work full time, neither of us are planning on being a SAHP or going part-time.
I am not naive - despite knowing that we are as committed to one another as we can be without marriage, I know that in the eyes of UK law we are not considered equal with a married couple. Are there practical or child-rearing related reasons that we should get married? Is there anything we should be setting up administratively in advance of the birth, given that we are not married (i.e. in case medical decisions need to be made)? What am I missing?! Thank you for reading.
