Or rather adding my own surname after XH's.
Last summer we had a conversation in which he told me he presumed I would revert to my maiden name (correct) and that if I wanted to add it to DD's name (ie double barrell her) then he would agree.
I'm expecting decree absolute any day now and will formally change back asap. Since I'm in the process of registering DD for pre-school I decided I may as well do hers at the same time. I mentioned it this morning when I dropped her off with him and he's now told me there's no way he'll give his consent, despite what he said last year.
Is there any way around this?
