Change DS's name?

[Lemoncup]

Debating whether or not to change DS surname, the options are to change his name or I keep my married name

My husband left me for another woman a few months ago. I would like to have the same surname as my son for several reasons. STBXH has said he would give permission to change DS name but isn't very comfortable with it. We were initially going to double barrel DS surname but decided against it so that he would carry on his fathers family name but when/if he has children with the OW they'll carry on his family's name.
The other option is for me to keep my married name, I'd rather get rid but I would really like the same name as DS.

Change it while he’s agreeing

I don't tho know should change it at all.

That's your sons name, it's who he is. There's nothing wrong with parents and children having a different surname.

Better to change it now, while you can. It's safer if you both have the same name - if there's an emergency at school they'll know immediately who to call

I feel I should add that DS is only 1years old.

There's nothing wrong with it, it's just like I said I'd like to have the same name. I've heard it's better for school and travelling etc too.

Revert to your maiden name and change DSs to match as your Ex is agreeing.
