FiL wants all our data

[HighlandCowSaysBooNotMoo]

My father in law works in a government role.
Today he put a message in the family WhatsApp group asking if we could send him our addresses, d.o.bs, mothers maiden names, our place of birth, our address history, previous maiden names etc.
Apparently he needs this info from his 4 adult children, their spouses (me included) , his own siblings and his siblings spouses, grandchildren, his in laws etc. Basically he is covering every member of the family and spouses etc over the age of 18.
He has put something light hearted about it being needed for an enhanced security check that he's been told he needs for his job.
He is not changing jobs or position in the company. He has been in this job for since my husband was a wee kid!!
A couple of people have responded straight away with their data.
DH says IABU not to share mine with his dad
What do I do?

Ignore the silly responses saying it is sinister. It’s totally normal. And it can absolutely happen during a job role without any changes. They’re checking him out, not you. They just want details of anyone close to him who might blackmail him. depending on the level of security clearance (I suspect DV) they will interview some of you and ask, for example, if he’s gay. Obviously they’re not going to view someone negatively for being gay, but they will be checking your answers match up, to see how likely it is that he would be blackmailed. You are being very unreasonable if you don’t comply, because he could lose his job or be demoted at least.

My family have to give me this info for my job. Vetting needs redoing every so often. No one has ever had an issue with it

I’ve never had to do that! Maybe I’m not reading it correctly 😬

Honestly really it's just your dob and place of birth which any one with a good snoop of face book and LinkedIn would be able to tell him.
I couldn't get worked up over this .

My dad wouldn’t have a clue- he doesn’t even know details of his own flipping life. I needed to know his and my mums wedding date and neither of them had a clue. We had to search their house for a wedding certificate which we didn’t find. In the end I had to message all their siblings to see if any of them could remember when and where my parents got married!

From what I know of similar from family members, they already have your information. A previous partner had to also give details of our kink club exploits, but somehow they already knew it all. They wanted to check they are being honest. It's pretty normal procedure.

I'm glad it's not just me.

I stuffed up a financial thing cos I couldn't remember my parents birthdays

Not just you- I never remember birthdays!
