Well, obviously, only you can decided for yourself. However, when I was in private practice in general:
1. 90 percent of childless women chose to revert back to their maiden name.
2. About 50 percent of those women who had children of the marriage chose to keep the name as is, so it would be the same as the children's last name.
3. The other 50 percent or so decided to revert back to their maiden name, usually because they hated the spouse so much they did not want to keep the name. In many of these cases the children were older and so knew what was going on.
In a few cases the women would keep the spouses' name because of credit issues; in some other cases the women would change their last name because of credit issues.
Sometimes the women would ask me what I recommended. I would give them the official 'French Shoulder Shrug'.
