Temporary Mezuzos

Question: We asked a sofer to come to our house to check our mezuzos. He said that it would take him a couple of days until he could return them. Do we need to put up other mezuzos in the meantime?

Answer: The Pri Megadim (Eshel Avraham OC 38:15) writes that one must not remain in a house without a mezuza. Thus, if a mezuza falls down on Shabbos or Yom Tov, one must vacate their home and move into another house if they have one. The Pischei Teshuva (YD 285:1) adds that this halacha applies equally to the weekday, and one may only stay in their home if they do not have another home to go to. Nonetheless, R’ Ephraim Greenblatt (Rivevos Ephraim 2:28:4; 5:548) quotes R’ Chaim Kanievsky who maintained that one is not required to leave a home without a mezuza.

R’ Moshe Sternbuch (Teshuvos Vehanhagos 1:643) notes that people often remove their mezuzos unnecessarily as a good mezuza on an internal door should not need checking regularly. It is advisable for a sofer to have spare mezuzos that he can affix, particularly for when one owns the house.

Nonetheless, R’ Avraham Dovid Wahrman (Daas Kedoshim 291:1) writes that if one removes one’s mezuzos to be checked, one is not required to replace them in the interim. One would only need to replace them if it would take a while to find someone to ask. R’ Ephraim Greenblatt quotes the Emek Beracha who explains that chazal never required that one replace the mezuzos while they are being checked. R’ Dovid Feinstein relates that his father, R’ Moshe, would remove all of his mezuzos together to be checked, rather than check them one at a time.

R' Shamai Gross (Shevet Hakehasi 1:273) writes that while one does not need to replace one’s mezuzos while they are being checked, it is commendable to place one on one’s front door.

In conclusion, one is not obligated to affix temporary mezuzos when one removes theirs to have them checked. If a mezuza is found to be passul, one must replace it immediately, if necessary, by borrowing one until one can buy a new one. Ideally, one should ensure that there is a mezuza on their front door overnight.
