Would my filing bankruptcy affect my fiance?

Your question is a bit confusing. There is no 'judgment' as such in a typical bankruptcy case. You file the case, there is a meeting of creditors a month or so after, and if no creditor or Trustee tries to exclude some particular claim, or all claims, from discharge, you receive the discharge after about 3 months in a Chapter 7. Furthermore, because of the Automatic Stay, no judgment can be entered against you from the instant you file the case. Doing so is a contempt of the federal court. Your lawyer can demand that the creditor vacate a judgment (obviously from a different court) if it is docketed after the Automatic Stay takes effect. If you don't have a skilled BR lawyer, it would be an excellent idea to retain one. That said, your fiance is not liable for any debts of yours which arose prior to your wedding.

It shouldn't affect your fiancee at all.

What judgment date? Bankruptcy does not involve judgments as a general rule. Do you possibly mean your discharge? Unless you had debt together, bankruptcy is unlikely to affect someone to whom you were not married at the time your bankruptcy was filed.

Confer with an attorney, but generally not.

You will want to marry after the case is closed.

That would be a no.
