if else set in SQL Server causes an error

if (datediff(day, ((select top 1 fec_ven 
                    from cxc_cuedoc 
                    inner join cxc_cuedoc cue on cli.cod_cli = cue.cod_cli  
                    where sal_doc != 0 and num_doc = cue.num_doc)), getdate())) > 110 
    and cue.tip_doc = '010'
begin
    update cxc_cliente
    set ind_mora ='2'

    set IND_JURIDICO = '2'
end
else 
begin
    set ind_mora ='1'
    set ind_juridico ='1'
end

I get an error on syntax after the first set... I don't know where the mistake is.
