Not taking the name is mutual give-and-take of respect, nothing more. So, it does not have any short-term problems, but it does have long-term effects when the opinions of the spouses clashes. Someone’s opinion has to prevail. If mutual respect is not there, the chances of a clash are more acute. But then, it depends upon the couples, after all.
If the collective wisdom of centuries provides that the names not be taken, we should be slow to interfere with it unless we have a damn good reason.

And why the hell not if husbands want to take their wives’ names? This part will have nothing to do when the couple lives happily ever after or if they decide to part ways.

There is wisdom in change, not just in tradition!

Years ago friend of mine marriage condition was her surname to be passed to kids by partner changing his surname to her family name.

They are not rich.

He has done as she wished, and they are a happy family proven by time going.

So sweet... And the point is- taking husband’s or wife’s name is not the issue..its actually about the understanding they share with each other that keeps a relationship going...

So be it anybody’s surname, the important thing is to love & respect each other
