RULE 20
               PERMISSIVE JOINDER OF PARTIES

    (a) Permissive Joinder. All persons may join in one action as
plaintiffs if they assert any right to relief jointly, severally, or in the
alternative in respect of or arising out of the same transaction,
occurrence or series of transactions or occurrences and if any question of
law or fact common to all of these persons will arise in the action. All
persons may be joined in one action as defendants if there is asserted
against them jointly, severally, or in the alternative, any right to relief
in respect of or arising out of the same transaction, occurrence, or series
of transactions or occurrences and if any question of law or fact common to
all of them will arise in the action. A plaintiff or defendant need not be
interested in obtaining or defending against all the relief demanded.
Judgment may be given for one or more of the plaintiffs according to their
respective rights to relief, and against one or more defendants according
to their respective liabilities.
    (b) Separate Trials. The court may make such orders as will prevent a
party from being embarrassed, delayed, or put to expense by the inclusion
of a party against whom he asserts no claim and who asserts no claim
against him, and may order separate trials or make other orders to prevent
delay or prejudice.
    (c) When Husband and Wife May Join. (Reserved. See RCW 4.08.040.)
    (d) Service on Joint Defendants; Procedure After Service. When the
action is against two or more defendants and the summons is served on one
or more but not on all of them, the plaintiff may proceed as follows:
    (1) If the action is against the defendants jointly indebted upon a
contract, he may proceed against the defendants served unless the court
otherwise directs; and if he recovers judgment it may be entered against
all the defendants thus jointly indebted so far only as it may be enforced
against the joint property of all and the separate property of the
defendants served.
    (2) If the action is against defendants severally liable, he may
proceed against the defendants served in the same manner as if they were
the only defendants.
    (3) Though all the defendants may have been served with the summons,
judgment may be taken against any of them severally, when the plaintiff
would be entitled to judgment against such defendants if the action had
been against them alone.
    (e) Procedure To Bind Joint Debtor. RCW 4.68 applies to the enforcement
of a judgment against a joint debtor.
