We just got a declaration from Joe Jackson, filed with the court, and Joe makes it clear -- he supported Michael Jackson's decision to make his wife Katherine the guardian of Michael's 3 kids .. and Joe makes it clear he will keep his distance.

Joe says in the declaration: "I have had a close family relationship with these grandchildren since their birth. I do visit the family residence from time to time and will continue to do so, however I will not be involved in raising the children."

Joe continues, "I understand that all decision-making authority regarding the children will rest with Katherine Jackson. Katherine Jackson is a wonderful caretaker and guardian, and has done an excellent job raising our children and other grandchildren."
