Anyone get their father added to their birth cert posthumously? (as an adult)

[NotMakingDinner]

Sorry it's not an AIBU but I need the traffic as this is a weird one.

We need to add Dh's father to his birth certificate so he can apply for citizenship of that country. Unfortunately, his father died 40 years ago and isn't here to take a DNA test.

Dh has uncles who I think would be willing to take a DNA test to prove their link to him. He also has a half sister who has taken an informal DNA test (ANcestry.com) and they've matched as half siblings. She has their father on her birth certificate. We could pay for her to have a legal DNA test to prove the link.

Currently, there is no one in the "father" section on DH's cert, if that is relevant.

I've asked and been in touch with local family law firms and no one had dealt with it and was passed other numbers.

I've researched and found cases where people were able to get DNA from a deceased person to add them to a child's birth certificate but nothing exactly like this.

Any thoughts?

I think in the case of bringing a partner I need to be the one with a job to start with though? Happy to be told I'm wrong! Unfortunately other than being fabulous I don't have any skills beyond minimum wage and we can't afford to live on my potential salary. Dh is the skilled worker and I've also been off having too many children in the time I've been unemployed which we all know employers love.

@iklboo the Good Friday agreement gives people living in NI the option of dual or Irish citizenship.

Ah thank you. That makes sense.

It is that automatic right if Irish, British (or both ) citizenship which formed the basis of the recent Emma de Souza local case. I believe the U.K. government only recognised her as a British citizen and were denying leave to remain or similar to her husband who was from a third country.

Irish passport applications are massively backlogged and take 2-3 months for a standard application, anything more complicated may take a while.

The Irish embassy staff were incredibly helpful when I applied.
I had to register as a foreign birth but my father had died many years previously. I didn’t have is birth certificate or even a definitive date of birth as my mother couldn’t remember exactly which year.

I supplied my birth certificate which he was named on, so probably easier. I knew the village he was born in and guessed he was baptised there. The embassy helped track his baptism certificate down. From that I was offered foreign birth registration.

I would suggest making contact and seeing if you can get someone to be a direct point of contact. It certainly made life easier having someone to speak with.
