Paragraph 19.4 Procedure for adding and substituting parties
The court’s permission is required to remove, add or substitute a party, unless the claim form has not been served.
An application for permission under paragraph (1) may be made by—
an existing party; or
a person who wishes to become a party.
An application for an order under rule 19.2(4) (substitution of a new party where existing party’s interest or liability has passed)—
may be made without notice; and
must be supported by evidence.
Nobody may be added or substituted as a claimant unless—
he has given his consent in writing; and
that consent has been filed with the court.
An order for the removal, addition or substitution of a party must be served on—
all parties to the proceedings; and
any other person affected by the order.
When the court makes an order for the removal, addition or substitution of a party, it may give consequential directions about—
filing and serving the claim form on any new defendant;
serving relevant documents on the new party; and
the management of the proceedings.
