Is an annulment recommended over divorce after 8 months of marriage.

That really depends on whether there are any complicated issues outstanding such as property distribution or the custody of minor children. Back in the day it might have been safe to assume that an 8-month marriage wouldn't involve children or property, but in this day and age all things are possible.  Perhaps you've been living together for years, have children together, etc. All things being equal, an annulment is better than a divorce, at least in the absence of children and property issues, because an annulment has the legal effect of treating the marriage as though it never took place. It's like going back in time and deciding not to get married in the first place. But it only really works if there are no child custody issues to sort out and no disputes about who is entitled to what property.
