Your call

They’re unusual in legal doc­u­ments, but I don’t object to columns in a long doc­u­ment like a contract or set­tle­ment agree­ment. Columns are an easy way to get a shorter and more leg­i­ble line length with­out hav­ing to use large mar­gins. On a stan­dard 8.5″× 11″ page, two or three columns are fine. Four is too many.

Usu­ally columns look neat­est when the rows of text are aligned ver­ti­cally between columns (i.e., as if they were sit­ting on the same base­line). Look at a decent news­pa­per for an exam­ple. Get­ting this result takes a lit­tle extra effort. Note your line spacing and make sure any space between paragraphs works out to a whole mul­ti­ple of the line spac­ing. The two most com­mon options: set space between para­graphs to zero, or set it to be the same as the line spac­ing.
