The passuk (Devarim 24:1,3) describes a get as a ספר כריתות, a “book of separation.” To that end, Chazal derive that a get must completely separate between them. A classic example of this is that a get given on condition must have an “end date” for the condition; a man can give a get on condition that his wife not drink wine during the next 30 days, but he cannot give it on condition that his wife not drink wine ever (Gittin 21a, etc.).
Does this extend to financial relations between them? If a woman rented property from her husband, must she terminate the lease for the get to be valid, or does the requirement that the get sever their connection only refer to things within the get’s power to sever, i.e., their original marriage? While I have never heard of such a Halacha, this question arose as I was attempting to answer this question, and I realized that this point was not as as clear as I imagined it was.
