I have two primary aged DC from a previous relationship which ended when DC were very young. DC have their dad's surname. They live with me as per court order and have contact with their dad.
Fast forward several years and I'm married to DH, we have a child together and we'd like us all to have the same surname.
DH has grown up as a father figure to DC and he would also love to have parental responsibility for them.
So what I'm asking you wise bunch is: do any of you have any experience of applying or gaining parental responsibility for a step parent and / or changing your children's surname. We'd like to know if it's worth applying for and how likely we are to succeed.
