LOS ANGELES , California ( CNN ) -- A will from Michael Jackson written in 2002 has been located , but it may be one of several , the Jackson family lawyer said Tuesday . Though a 2002 Michael Jackson will has been located , the family 's lawyer says there may be others . `` We need a certain amount of time to look at that , '' lawyer Londell McMillan said , referring to whether other wills exist . `` I do n't personally know , but it 's possible . '' Until now , the Jackson family has said it has not seen a will for the singer . Without a legal will , the division of his estate would be decided in court . The 2002 will surfaced Monday after a Los Angeles judge gave the singer 's mother , Katherine Jackson , temporary control of her son 's `` tangible personal property . '' The pop icon 's three children -- ages 7 , 11 and 12 -- were also placed under the temporary guardianship of Katherine Jackson . McMillan said he has seen the will but would not disclose its details . `` There is a process called 'probating the will ' that will validate any will in due course , '' he said . Probate is the legal process to prove whether a will is authentic and valid . The process is used to pass on items in the will from the deceased to the beneficiaries . The biological mother of Jackson 's two oldest children , Debbie Rowe , will be invited to a hearing Monday in which the judge will consider who should have custody of them . She has not publicly indicated whether she will challenge the Jacksons for custody . CNN 's Don Lemon contributed to this story .
