6Guardians: revocation and disclaimer
(1)An appointment under section 5(3) or (4) 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 the 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)An appointment under section 5(3) or (4) (including one made in an unrevoked will or codicil) is revoked if the person who made the appointment revokes it by a written and dated instrument which is signed—
(a)by him; or
(b)at his direction, in his presence and in the presence of two witnesses who each attest the signature.
(3)An appointment under section 5(3) or (4) (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 instrument by which it was made; or
(b)has some other person destroy that instrument in his presence.
(4)For the avoidance of doubt, an appointment under section 5(3) or (4) made in a will or codicil is revoked if the will or codicil is revoked.
(5)A person who is appointed as a guardian under section 5(3) or (4) may disclaim his appointment by an instrument in writing signed by him and made within a reasonable time of his first knowing that the appointment has taken effect.
(6)Where regulations are made by the Lord Chancellor prescribing the manner in which such disclaimers must be recorded, no such disclaimer shall have effect unless it is recorded in the prescribed manner.
(7)Any appointment of a guardian under section 5 may be brought to an end at any time by order of the court—
(a)on the application of any person who has parental responsibility for the child;
(b)on the application of the child concerned, with leave of the court; or
(c)in any family proceedings, if the court considers that it should be brought to an end even though no application has been made.
