How to defer jury duty in USA that may conflict with a scheduled trip? [closed]

I don't know specifically about Ohio, but I've been called for both federal and state jury service in New York. In both cases, I was called for a time during a trip out of town. In both cases, I received a postponement because of my plans. If I recall correctly, my statement to that effect was sufficient to have the service postponed without having to submit any actual evidence, though I remember having the impression that subsequent postponements might be scrutinized more closely. I suppose the statement was a signed statement under penalty of perjury, but I do not remember precisely.

Postponement of jury service because of travel is surely routine in Ohio as well. It should not be too hard to arrange. If there is no information about this in the letter she received, it will surely be mentioned in the actual summons. If the court that has called your fiancée does want evidence beyond her own statement, a photocopy of an airline reservation will almost certainly suffice.

(On the off chance that your fiancée is not a US citizen or is otherwise unqualified for jury service, of course, she should instead present evidence of her disqualification to the court instead of asking for a postponement.)
