Harrison Ford's ex-wife lost her battle with cancer in November (15), and her business manager has been trying to locate her will ever since.

Her money was placed in a trust, but without explicit instructions, it's not clear who Mathison intended as the beneficiaries, reports TMZ.com.

She and Ford, who were married from 1983 to 2004, had two children, Malcolm and Georgia, who are each expected to receive a chunk of the funds.

Mathison was also known for penning the screenplays for the movies Kundun, The Black Stallion, The Indian in the Cupboard, and Steven Spielberg's upcoming film adaptation of Roald Dahl's beloved children's novel, The BFG.
