Birth reregistration following marriage

[Staceyje]

Hello

Looking for some advice/support.
we got married in 2015 and had two children before we married and had one child after marriage.

I’ve been advised that I will need to re-register my two children born before marriage so that they become a child of marriage and all 3 children will then have equal rights of intestacy in the future.

My question is has anyone who had children done this? Would you advise/recommend I do. I have checked the gov website and it appears to be a legal requirement.

its free to do and seems straightforward but my two reservations are:
my eldest is 10 years old and therefore the date of registration on his birth certificate would be 10 years after he was born
it somehow feels like im messing up their birth record with a date some 10 and 8 years after they were born, is this something that they might have an issue or questions about in the future?

Any experiences of people who have re registered their children would be much appreciated 👍🏻

DH insisted on re-registering DS2 when we married two years after he was born. I was opposed to it because I feel it is re-writing history, but it was important to him so I allowed it. We were made aware that we could do it by the registrar when we booked our wedding, but she didn’t say anything about it being a legal requirement. I took it that it was something we could do if we wanted to, rather than were obliged to do. This was 30 years ago so I’m not up to date with how things are today.
