You and your fiance are opposing parties in this matter. Your lawyer cannot represent both of you, it's a conflict of interests. Having your fiance have her own representation ensures she cannot come back and claim she did not understand what she was signing, and/or gives the appearance of the entire transaction being professionally negotiated, and thus not so one sided that it could be thrown out. The whole thing would be an exercise in futility if your fiance didn't have her own lawyer.
