PARTIES TO A SUIT IN EQUIT

from Bouvier's Law Dictionary, Revised 6th Ed (1856)
PARTIES TO A SUIT IN EQUITY. The person who seeks a remedy in chancery by 
suit, commonly called a plaintiff, and the person against whom the remedy is 
sought, usually denominated the defendant, are the parties to a suit in 
equity. 
     2. It is of the utmost importance, that there should be proper parties; 
and therefore no rules connected with the science of equity pleading, are so 
necessary to be attentively considered and observed, as those which relate 
to the persons who are to be made parties. to a suit, for when a mistake in 
this respect is discovered at the hearing of the cause, it may sometimes be 
attended with defeat, and will, at least, be followed by delay and expense.

     3. A brief sketch will be here given by considering, 1. Who may be 
plaintiffs. 2. who may be made defendants. 3. The number of the parties. 
     4.-Sec. 1. Of the plaintiff. Under this head will be considered who 
may sue in equity: and, 
     5.-1. The government, or as the style is in England, the crown) may 
sue in a court of equity, not only in suits strictly on behalf of the 
government, for its own peculiar rights and interest, but also on behalf of 
the rights and interest of those, who partake of its prerogatives, or claim 
its peculiar protection. Mitf. Eq. Plead. by Jeremy, 4, 21-24; Coop. Eq. 21, 
101. Such suits  are usually brought by the attorney general. 
     6.- 2. As a general rule all persons, whether natural or artificial, as 
corporations, may sue in equity; the exceptions are persons who are not sui 
juris, as a person not of full age, a feme covert, an idiot, or lunatic. 
     7. The incapacities to sue are either absolute, or partial. 
     8. The absolute, disable the party to sue during their continuance; the 
partial, disable the party to sue by himself alone, without the aid of 
another. In the United States, the principal ab solute incapacity, is 
alienage. The alien, to be disabled to sue in equity, must be an alien 
enemy, for an alien friend may sue in chancery. Mitf. Equity, PI, 129; Coop. 
Equity Pl. 27. But still the subject matter of the suit may. disable an 
alien to sue. Coop. Eq. Pl. 25; Co. Lit. 129 b. An alien sovereign or an 
alien corporation may maintain a suit in equity in this country. 2 Bligh's 
Rep. 1, N. S.; 1 Dow. Rep.. 179, N. S.; 1 Sim. R. 94; 2 Gall. R. 105; 8 
Wheat. Rep. 464; 4 John. Ch. Rep. 370. In case if a foreign sovereign, he 
must have been recognized by the government of this country before he can 
sue. Story's Eq. pl. Sec. 55; 3 Wheat. Rep. 324; Cop. Eq. Pl. 119 
     9. Partial incapacity to sue exists in the case of infants, of married 
women, of idiots and lunatics, or other persons who are incapable, or are by 
law specially disabled to sue in their own names; as for example, in 
Pennsylvania, and some other states, habitual drunkards, who are under 
guardianship. 
    10.-1. An infant cannot, by himself, exhibit a bill, not only on account 
of his want of discretion, but because of his inability to bind himself for 
costs. Mitf. Eq. Pl. 25. And when an infant sues, he must sue by his next 
friend. Coop, Eq. 27; 1 Sm. Chan. Pl. 54. But as the next friend may 
sometimes bring a bill. from improper motives, the court will, upon a proper 
application, direct the master to make inquiry on this subject, and if there 
be reason to believe it be not brought for the benefit of the infant, the 
proceedings will be stayed. 3 P. Wms. 140; Mitf. Eq. Pl. 27; Coop. Eq. Pl. 
28. 
    11.-2. A feme covert must, generally, join with her husband; but when 
he has abjured the realm, been transported for felony, or when he is civilly 
dead, she may sue as a feme sole. And when she has a separate claim, she may 
even sue her husband, with the assistance of a next friend of her own 
selection. Story's Eq. Pl. Sec. 61; Story's Eq. Jur. Sec. 1368; Fonb. Eq. 
b. 1, c. 2, Sec. 6, note p. And the husband may himself sue the wife. 
    12.-3. Idiots and lunatics are generally under the guardianship of 
persons who are authorized to bring a suit in the idiot's name, by their 
guardian or committee. 
    13.-Sec. 2. Of the defendant. 1. In general, those persons who may sue 
in equity, may be sued. Persons sui juris may defend themselves, but those 
under an absolute or partial inability, can make defence only in a 
particular manner. A bill may be exhibited against all bodies politic or 
corporate, against all persons not laboring under any disability, and all 
persons subject to such incapacity, as infants, married women, and lunatics, 
or habitual drunkards.  
    14.-2. The government or the state, like the king in England, cannot 
be sued. Story, Eq. Pl. Sec. 69. 
    15.-3. Bodies politic or corporate, like persons sui juris, defend a 
suit by themselves. 
    16.-4. Infants institute a suit, as has been seen, by next friend, but 
they must defend a suit by guardian appointed by the court, who is usually 
the nearest relation, not concerned in interest, in the matter in  question. 
Mitf. Eq. Pl. 103; Coop. Eq. Pl. 20, 109; 9 Ves. 357; 10 Ves. 159; 11 Ves. 
563; 1 Madd. R. 290; Vide Guardian, n. 6. 
    17.-5. Idiots and lunatics defend by their committees, who, in 
ordinary circumstances, are appointed guardians ad litem, for that purpose, 
as a matter of course. Mitf. Eq. Pl. 103; Coop. Eq. Pl. 30, 32; Story's Eq. 
Pl. SS70; Shelf on Lun. 425.; and vide 2 John. Ch. R. 242, where, Chancellor 
Kent held, that the idiot need not be made a party as defendant to a bill 
for the payment of his debts, but his committee only. When the idiot or 
lunatic has no committee, or the latter has an interest adverse to that of 
the lunatic or idiot, a guardian ad litem will be appointed Mitf. Eq. Pl. 
103;; Story's Eq. Pl. Sec. 70. 
    18.-6. In general, a married woman, when she is sued, must be joined 
with her husband, and their answer must also be joint. But there axe 
exceptions to this rule in both its requirements. 
    19.-1. A married woman may be made a defendant, and answer as a feme 
sole, in some instances, as when her husband is plaintiff in the suit, and 
sues her as defendant, and from the like necessity, when the husband is an 
exile or has abjured the realm, or has been transported under a criminal 
sentence, or is an alien enemy. She may be sued and answer as a feme sole. 
Mitf. Eq. Pl. 104, 105; Coop. Eq. Pl. 30. 
    20.-2. When her husband is joined, or ought to be joined, she cannot 
make a separate defence, without a special order of court. The following are 
instances where such orders will made. When a married woman claims as 
defendant in opposition to her husband, or lives separate from him, or 
disapproves of the defence he wishes her to make, she may obtain an order of 
court for liberty to answer, and defend the suit separately. And when the 
husband is abroad, the plaintiff may obtain, an order that she shall answer 
separately; and, if a woman obstinately refuses to join a defence with her 
husband, the latter may obtain an order to compel her to make a separate 
answer. Mitf. Eq: Pl.: 104; Coop. Eq. Pl. 30; Story's Eq 71. 
    21.-3. As to the number of parties. It is a general rule that every 
person who is at all interested in the subject-matter of the suit, must be 
made a party. It is, the constant aim of a court of equity, to do complete 
justice by deciding upon and settling the rights of all persons interested 
in the subject of the suit, to make the performance of the order of the 
court perfectly safe to those who are compelled to obey it, and, to prevent 
future litigation. For this purpose, all persons materially interested in 
the subject ought to be parties to the suit, plaintiffs or defendants, 
however numerous they may be, so that a complete decree may be made binding 
on those parties. Mitford's Eq. Pl. 144; 1 John. Ch. R. 349; 9 John. R. 442; 
2 Paige's C. R. 278; 2 Bibb, 184; 3 Cowen's R. 637; 4 Cowen's R. 682 9 
Cowen's R. 321; 2 Eq. Cas. Ab. 179; 3 Swans. R. 139. When a great number of 
individuals are interested as in the instance of creditors seeking an 
account of the estate of their deceased debtor for payment of their demands, 
a few suing on behalf of the rest may substantiate the suit, and the other 
creditors may come in under the decree. 2 Ves. 312, 313. In such case the 
bill should expressly show that it is fifed as well on the behalf of other 
members as those who are really made the complainants; and the parties must 
not assume a corporate, name, for if they assume the style of a corporation, 
the bill cannot be sustained. 6 Ves. jr. 773; Coop. Eq. Pl. 40; 1 John. Ch. 
R. 349; 13 Ves. jr. 397 16 Ves. jr. 321; 2 Ves. sen. 312 S. & S. 18; Id. 
184. In some cases, however, when all the persons interested are, not made 
parties, yet, if there be such privily between the plaintiffs and 
defendants, that a complete decree may be made, the want of parties is not a 
cause of demurrer. Mitf. El q. Pl. 145. Vide Calvert on Parties to Suits in 
Equity; Edwards on Parties to Bills in Chancery; Bouv Inst. Index, h.t.
