In this paper, by deriving the expressions for double-lepton polarization asymmetries for B to a scalar meson transition in SM and SM4 and considering the corresponding uncertainties in SM we investigate the indirect effects of the fourth generation of quarks on such asymmetries in the B{yields}K{sub 0}*(1430)l{sup +}l{sup -} decay. We also compare these asymmetries with those of B{yields}Kl{sup +}l{sup -} decay and find out that most of these asymmetries behave similarly to the corresponding asymmetries for B{yields}Kl{sup +}l{sup -} decay. We finally show that in the {mu} channel all asymmetries, except <P{sub LL}>, and in {tau} channel only <P{sub LN}> can manifest the influence of the fourth generation at the minimum value of m{sub t}{sup '} around 200 GeV. In addition, it is shown that for the {tau} channel the asymmetries such as <P{sub LL}>, <P{sub NN}>, and <P{sub TT}> can indicate the effect of such new physics at m{sub t}{sup '}{>=}300 GeV. Hence, the B{yields}K{sub 0}{sup *}(1430)l{sup +}l{sup -} decay is a valuable tool for probing new physics beyond SM, especially in the indirect searches of the fourth generation of quarks (t{sup '},b{sup '}) via its manifestations in loop diagrams.
