Does a clinic have to tell a husband when his wife is having an abortion?
Not in the United States of America. Not only doesn't a clinic have to tell a husband about his wife's medical care, they legally can't do this without her consent.
In the US a woman has rights to both bodily autonomy and privacy. This means she both gets to decide what is/is not done to her body and also whether or not she wants to disclose this information to others.
I'm not sure about other jurisdictions.
