Maiden name/Legal name
I know a variety of women who have retained their maiden names for publications (some because they started publishing before getting married and changing their legal name). If they had been publishing before getting married, one concern is making it easy to link all their publications under one author name, making it easier to see their whole record. (But, even that is not required, having seen publication lists where it rapidly becomes clear that there was a name change - I hope things like Web of Science figure it out, but I'm not sure.) 

I also know a number that never changed their name legally to begin with. That is not uncommon, at least in the US. 

Likely you know such people as well, or looking around your university would find some fairly quickly. 

So, bottom line, do what you and your partner are comfortable with, the academic world has seen it before and is just fine with it.
