against whom enforcement is sought proves either of the following:
(1) That party did not execute the agreement voluntarily.
(2) The agreement was unconscionable when it was executed and,
before execution of the agreement, all of the following applied to
that party:
(A) That party was not provided a fair, reasonable, and full
disclosure of the property or financial obligations of the other
party.
(B) That party did not voluntarily and expressly waive, in
writing, any right to disclosure of the property or financial
obligations of the other party beyond the disclosure provided.
(C) That party did not have, or reasonably could not have had, an
adequate knowledge of the property or financial obligations of the
other party.
(b) An issue of unconscionability of a premarital agreement shall
be decided by the court as a matter of law.
(c) For the purposes of subdivision (a), it shall be deemed that a
premarital agreement was not executed voluntarily unless the court
finds in writing or on the record all of the following:
(1) The party against whom enforcement is sought was represented
by independent legal counsel at the time of signing the agreement or,
after being advised to seek independent legal counsel, expressly
waived, in a separate writing, representation by independent legal
counsel.
(2) The party against whom enforcement is sought had not less than
seven calendar days between the time that party was first presented
with the agreement and advised to seek independent legal counsel and
the time the agreement was signed.
(3) The party against whom enforcement is sought, if unrepresented
by legal counsel, was fully informed of the terms and basic effect
of the agreement as well as the rights and obligations he or she was
giving up by signing the agreement, and was proficient in the
language in which the explanation of the party's rights was conducted
and in which the agreement was written. The explanation of the
rights and obligations relinquished shall be memorialized in writing
and delivered to the party prior to signing the agreement. The
unrepresented party shall, on or before the signing of the premarital
agreement, execute a document declaring that he or she received the
information required by this paragraph and indicating who provided
that information.
(4) The agreement and the writings executed pursuant to paragraphs
(1) and (3) were not executed under duress, fraud, or undue
influence, and the parties did not lack capacity to enter into the
agreement.
(5) Any other factors the court deems relevant.
