The basic idea of the UN Charter is given in article 1, which in part 2 says "To develop friendly relations among nation based on respect for the principle of equal right and self-determination of people, and to take other appropriate measures to strengthen universal peace"
The Charter in chapter 11 provides respect for the equal rights & self-determination of Non-Self-Governing territories which are occupied by UN members by telling those UN nations how to treat the non-self-governing territories.
The Charter in chapter 12 defines a "Trusteeship System" by which the UN can occupy or administrate a non-self-governing territory, a "trust territory". The chapter allows options for either the UN or a member of the UN to be the colonial power to occupy and administrate the trust territory.
Finally, the Charter in chapter 13 creates a Trusteeship Council and explains obligations which the Trusteeship Council has towards non-self-governing territories which are subject to the Trusteeship System.
