New York Laws
Article 9 - Action to Annul a Marriage or Declare It Void
140 - Action for Judgment Declaring Nullity of Void Marriages or Annulling Voidable Marriage.

(b) Party under age of consent. An action to annul a marriage on the
ground that one or both of the parties had not attained the age of legal
consent may be maintained by the infant, or by either parent of the
infant, or by the guardian of the infant's person; or the court may
allow the action to be maintained by any person as the next friend of
the infant. But a marriage shall not be annulled under this subdivision
at the suit of a party who was of the age of legal consent when it was
contracted, or by a party who for any time after he or she attained that
age freely cohabited with the other party as husband or wife.
(c) Party a person with a developmental illness or person with a
mental illness. An action to annul a marriage on the ground that one of
the parties thereto was a person with a developmental disability may be
maintained at any time during the life-time of either party by any
relative of a person with a developmental disability, who has an
interest to avoid the marriage. An action to annul a marriage on the
ground that one of the parties thereto was a person with a mental
illness may be maintained at any time during the continuance of the
mental illness, or, after the death of the person with a mental illness
in that condition, and during the life of the other party to the
marriage, by any relative of the person with a mental illness who has an
interest to avoid the marriage. Such an action may also be maintained by
the person with a mental illness at any time after restoration to a
sound mind; but in that case, the marriage should not be annulled if it
appears that the parties freely cohabited as husband and wife after the
person with a mental illness was restored to a sound mind. Where one of
the parties to a marriage was a person with a mental illness at the time
of the marriage, an action may also be maintained by the other party at
any time during the continuance of the mental illness, provided the
plaintiff did not know of the mental illness at the time of the
marriage. Where no relative of the person with a developmental
disability or person with a mental illness brings an action to annul the
marriage and the person with a mental illness is not restored to sound
mind, the court may allow an action for that purpose to be maintained at
any time during the life-time of both the parties to the marriage, by
any person as the next friend of the person with a mental illness or
person with a developmental disability.
(d) Physical incapacity. An action to annul a marriage on the ground
that one of the parties was physically incapable of entering into the
marriage state may be maintained by the injured party against the party
whose incapacity is alleged; or such an action may be maintained by the
party who was incapable against the other party, provided the incapable
party was unaware of the incapacity at the time of marriage, or if aware
of such incapacity, did not know it was incurable. Such an action can be
maintained only where an incapacity continues and is incurable, and must
be commenced before five years have expired since the marriage.
(e) Consent by force, duress or fraud. An action to annul a marriage
on the ground that the consent of one of the parties thereto was
obtained by force or duress may be maintained at any time by the party
whose consent was so obtained. An action to annul a marriage on the
ground that the consent of one of the parties thereto was obtained by
fraud may be maintained by the party whose consent was so obtained
within the limitations of time for enforcing a civil remedy of the civil

practice law and rules. Any such action may also be maintained during
the life-time of the other party by the parent, or the guardian of the
person of the party whose consent was so obtained, or by any relative of
that party who has an interest to avoid the marriage, provided that in
an action to annul a marriage on the ground of fraud the limitation
prescribed in the civil practice law and rules has not run. But a
marriage shall not be annulled on the ground of force or duress if it
appears that, at any time before the commencement of the action, the
parties thereto voluntarily cohabited as husband and wife; or on the
ground of fraud, if it appears that, at any time before the commencement
thereof, the parties voluntarily cohabited as husband and wife, with a
full knowledge of the facts constituting the fraud.
(f) Incurable mental illness for five years. An action to annul a
marriage upon the ground that one of the parties has been incurably
mentally ill for a period of five years or more may be maintained by or
on behalf of either of the parties to such marriage.
