The former Diff'rent Strokes star's affairs have been thrown into disarray since his death last month (May10) after he allegedly failed to leave strict instructions regarding the division of his assets.
His ex-wife Shannon Price filed a handwritten addendum in court last week (ends11Jun10) in an effort to get her share of Coleman's estate and the actor's TV brother Todd Bridges and one-time manager Dion Mial both claim they have directives from the former child star too.
But in a new document executed in February, 2005, and filed in Utah on Friday (11Jun10), Coleman left everything to a woman called Anna Gray. Price was not mentioned in the latest will, reports the Associated Press.
And the discovery has prompted Mial to halt attempts to win legal control over Coleman's estate, his attorney, Alderman Ken, has confirmed.
Gray, who is believed to be Coleman's ex-girlfriend and one of his most trusted pals, filed documents with a court in Provo, Utah stating her inclusion as a trustee in a 2005 will.
A hearing regarding Coleman's estate is expected to take place in Provo on Monday (14Jun10).
Coleman died on 28 May (10) after suffering a brain haemorrhage following a fall at home. An autopsy was completed last week (ends13Jun10) and coroners have ruled his death an accident, listing chronic renal failure as a contributing factor to the actor's death.
