1,732. The Legibility of a Get; Ambiguity

Hilchos Geirushin 4:10

Regardless of the alphabet used in a get, the handwriting must be clear enough that even children who know that alphabet will be able to read it. This refers not to children who are particularly gifted, nor those who are remedial; it refers to the average child. The handwriting must be neither crooked nor illegible out of concern that one letter might be mistaken for another, changing the document’s meaning.

Hilchos Geirushin 4:11

If a get can be understood in two ways, or if the writing is sufficiently ambiguous that it could be understood to mean something else, it is unusable, though not inherently invalid since it could be understood to effect divorce. While a get may be written in any language, the universal practice has become to write a get in Aramaic, using the text that will follow in the next halacha.
