(1)An appointment made under section 7(1) or (2) of this Act revokes an earlier such appointment (including one made in an unrevoked will or codicil) made by the same person in respect of the same child, unless it is clear (whether as a result of an express provision in the later appointment or by any necessary implication) that the purpose of the later appointment is to appoint an additional guardian.
(2)Subject to subsections (3) and (4) below, the revocation of an appointment made under section 7(1) or (2) of this Act (including one made in an unrevoked will or codicil) shall not take effect unless the revocation is in writing and is signed by the person making the revocation.
(3)An appointment under section 7(1) or (2) of this Act (other than one made in a will or codicil) is revoked if, with the intention of revoking the appointment, the person who made it—
(a)destroys the document by which it was made; or
(b)has some other person destroy that document in his presence.
(4)For the avoidance of doubt, an appointment made under section 7(1) or (2) of this Act in a will or codicil is revoked if the will or codicil is revoked.
(5)Once an appointment of a guardian has taken effect under section 7 of this Act, then, unless the terms of the appointment provide for earlier termination, it shall terminate only by virtue of—
(a)the child concerned attaining the age of eighteen years;
(b)the death of the child or the guardian; or
(c)the termination of the appointment by a court order under section 11 of this Act.
