TMZ has learned Brittany Murphy had a will when she died -- a will she executed before she met husband Simon Monjack.
Sources say the will left her estate to her mother, Sharon Murphy.
The house Brittany owned and died in was held in trust -- a trust created several years before she met Monjack. He is not listed on the title.
We do not know if Murphy amended her will after she was married. So far we have no evidence Murphy drafted a codicil (amendment) to the will.
