The Dalitz decay of the {ital K}{sub {ital L}} meson is investigated in consistency with the approximate {parallel}{Delta}{ital I}{parallel}=1/2 rule in the {ital K}{r_arrow}{pi}{pi} decays, the {ital K}{sub {ital L}}-{ital K}{sub {ital S}} mass difference, and the {ital K}{sub {ital L}}{r_arrow}{gamma}{gamma} decay. The form factor for the Dalitz decay is compared with the existing data from {ital K}{sub {ital L}}{r_arrow}{gamma}{ital e}{sup +}{ital e}{sup {minus}} and {gamma}{mu}{sup +}{mu}{sup {minus}}. It is demonstrated that vector meson poles can play an important role. {copyright} {ital 1996 The American Physical Society.}
