Responsa for Bava Batra 342:13
אי הכי שטרי הלואה נמי זמנין דיזיף בניסן וכתיב ליה שטרא בתשרי ומתרמי ליה זוזי ביני ביני ופרע ליה ואמר ליה הב לי שטראי וא"ל אירכס לי וכתיב ליה תברא וכי מטי זמניה מפיק ליה וא"ל הני השתא הוא דיזפת מינאי

Teshuvot Maharam
A. A trustee appointed by both parties is not required to take an oath regarding the terms of his trusteeship. But, Leah was not appointed trustee by both parties. She was only appointed by the husband, and, therefore, is required to take an oath. Leah's husband cannot object to imposing an oath on her. If the law requires that a woman take an oath, the husband has no right to protest against her being degraded in court. But, since Leah, as long as she is married, has no money of her own, and were she to claim that she had already returned the deposit, no oath would be imposed on her, we now lend credence to her words and require no oath. However, the court should give A a writ stating that after Leah will be divorced or widowed she will have to return the money to A or take an oath to the effect that A deposited the money with her on condition that she return it upon his wife's consent only.
