Katherine Willing To Share Guardianship of Michael Jackson's Kids

Katherine's attorney, Perry Sanders, told TMZ last week that TJ and Katherine will file a request for JOINT GUARDIANSHIP with the court... and they expect it will be approved.

Perry tells us, "That pleading will essentially now legally reflect how Mrs. Jackson and TJ have often shared responsibilities of raising the children since Michael Jackson's tragic passing."

Katherine's lawyer says the new arrangement "reflected the wishes of [Michael Jackson's] children" ... Paris, Prince and Blanket.

If the court grants the joint request, Katherine's lawyer says TJ will be able to assume a lot of the day-to-day responsibilities that have been stressing Katherine out ... including management of household personnel and security.

"It will also make clear for school personnel and anyone else coming into contact with the children that TJ is authorized to act on their behalf," Perry tells TMZ.

"Mrs. Jackson will then be freed up to focus on the more personal everyday decision making related to the lives and activities of the children."

Katherine's lawyer says the agreement would still empower Katherine to CONTROL THE FAMILY'S ALLOWANCE ... which is $70k per month.

The arrangement also seems to make TJ a shoo-in to become the SOLE guardian of the children if Katherine dies while they are still minors.
