In any case where the court has power to include an exclusion requirement in an interim care order, the court may accept an undertaking from the relevant person.
No power of arrest may be attached to any undertaking given under subsection (1).
An undertaking given to a court under subsection (1)—
shall be enforceable as if it were an order of the court, and
shall cease to have effect if, while it is in force, the local authority have removed the child from the dwelling-house from which the relevant person is excluded to other accommodation for a continuous period of more than 24 hours.
This section has effect without prejudice to the powers of the High Court and family court apart from this section.
In this section "exclusion requirement" and "relevant person" have the same meaning as in section 38A.
