Hi wondering if anyone can point me in the right direction pls.

I have just bought and more or less moved in to the new house and put the house in the name of my son, so his name is on chanote and blue book.

What would be my process for reporting new address?

My son is only 5 so can’t obviously sign any documents also I have full custody of my son so his mother isn’t involved in any of this.

Would it be a case of taking copies / original chanote / his blue book / sons passport pics to immigration to update new address?

Can anyone advise?

Thanks
