The X Factor judge's lawyers filed the papers at London's High Court yesterday afternoon at 2pm.
Cheryl, 26, is citing 'unreasonable behaviour' as the reason for ending their 3-year marriage.
'She wants a completely clean break with no malice or wrangling over property or money,' a source tells The Sun.
'She will not take one penny of Ashley's money.'
Cheryl split from Chelsea footballer Ashley, 29, in February following allegations he cheated on her.
