Even Haezer Hl. Gittin 126 : 7
Due to the fact that there is a machlokes , how to spell the month
"Iyar"*
(one yud or two) . We refrain to write Gittin in the month of
Iyar, unless
there might be a possibility of Igun. (Aguna)
* Halacha Lma'aseh Iyar is spelled with two yudin if get was
spelled
with one yud it's pasul.
