 (from Ch. 40, par. 510)Sec. 510. Modification and termination of provisions for  maintenance, support, educational expenses, and property disposition.(a) Except as otherwise provided in paragraph (f) of Section 502 and  in subsection (b), clause (3) of Section 505.2, the provisions of any  judgment respecting maintenance or support may be modified only as to  installments accruing subsequent to due notice by the moving party of the  filing of the motion for modification. An order for child  support may be modified as follows:(1) upon a showing of a substantial change in     circumstances; and(2) without the necessity of showing a substantial     change in circumstances, as follows:(A) upon a showing of an inconsistency of at         least 20%, but no less than $10 per month, between the amount of the existing order and the amount of child support that results from application of the guidelines specified in Section 505 of this Act unless the inconsistency is due to the fact that the amount of the existing order resulted from a deviation from the guideline amount and there has not been a change in the circumstances that resulted in that deviation; or(B) upon a showing of a need to provide for the         health care needs of the child under the order through health insurance or other means.The provisions of subparagraph (a)(2)(A) shall apply only  in cases in which a party is receiving child support  enforcement services from the Department of Healthcare and Family Services under  Article X of the Illinois Public Aid Code, and only when at least 36  months have elapsed since the order for child support was entered or last  modified.The court may grant a petition for modification that seeks to apply the changes made to subsection (a) of Section 505 by Public Act 99-764 to an order entered before the effective date of Public Act 99-764 only upon a finding of a substantial change in circumstances that warrants application of the changes. The enactment of Public Act 99-764 itself does not constitute a substantial change in circumstances warranting a modification.(a-5) An order for maintenance may be modified or terminated only upon a  showing of a substantial change in circumstances. The court may grant a petition for modification that seeks to apply the changes made to Section 504 by this amendatory Act of the 100th General Assembly to an order entered before the effective date of this amendatory Act of the 100th General Assembly only upon a finding of a substantial change in circumstances that warrants application of the changes. The enactment of this amendatory Act of the 100th General Assembly itself does not constitute a substantial change in circumstances warranting a modification.  In all such proceedings, as  well as in proceedings in which maintenance is being reviewed, the court shall  consider the applicable factors set forth in subsection (a) of Section 504 and  the following factors:(1) any change in the employment status of either     party and whether the change has been made in good faith;(2) the efforts, if any, made by the party receiving     maintenance to become self-supporting, and the reasonableness of the efforts where they are appropriate;(3) any impairment of the present and future earning     capacity of either party;(4) the tax consequences of the maintenance payments     upon the respective economic circumstances of the parties;(5) the duration of the maintenance payments     previously paid (and remaining to be paid) relative to the length of the marriage;(6) the property, including retirement benefits,     awarded to each party under the judgment of dissolution of marriage, judgment of legal separation, or judgment of declaration of invalidity of marriage and the present status of the property;(7) the increase or decrease in each party's income     since the prior judgment or order from which a review, modification, or termination is being sought;(8) the property acquired and currently owned by each     party after the entry of the judgment of dissolution of marriage, judgment of legal separation, or judgment of declaration of invalidity of marriage; and(9) any other factor that the court expressly finds     to be just and equitable.(a-6) (Blank).(b) The provisions as to property disposition may not be revoked or  modified,  unless the court finds the existence of conditions that justify the  reopening of a judgment under the laws of this State.(c) Unless otherwise agreed by the parties in a written agreement  set forth in the judgment or otherwise approved by the court, the obligation  to pay future maintenance is terminated upon the death of either party, or  the remarriage of the party receiving maintenance, or if the party  receiving maintenance cohabits with another person on a resident,  continuing conjugal basis. An obligor's obligation to pay maintenance or unallocated maintenance terminates by operation of law on the date the obligee remarries or the date the court finds cohabitation began. The obligor is entitled to reimbursement for all maintenance paid from that date forward. Any termination of an obligation for maintenance as a result of the death of the obligor, however, shall be inapplicable to any right of the other party or such other party's designee to receive a death benefit under such insurance on the obligor's life. An obligee must advise the obligor of his or her intention to marry at least 30 days before the remarriage, unless the decision is made within this time period. In that event, he or she must notify the obligor within 72 hours of getting married.(c-5) In an adjudicated case, the court shall make specific factual findings as to the reason for the modification as well as the amount, nature, and duration of the modified maintenance award.(d) Unless otherwise provided in this Act, or as agreed in writing or  expressly  provided in the  judgment, provisions for the support of a child are terminated by emancipation  of the  child, or if the child has attained the age of 18 and is still attending  high school,  provisions for the support of the child are terminated upon the date that the  child  graduates from high school or the date the child attains the age of 19,  whichever is  earlier, but not by the death of a parent obligated to support or educate the  child.  An existing obligation to pay for support  or educational expenses, or both, is not terminated by the death of a  parent.  When a parent obligated to pay support or educational  expenses, or both, dies, the amount of support or educational expenses, or  both, may be enforced, modified, revoked or commuted to a lump sum payment,  as equity may require, and that determination may be provided for at the  time of the dissolution of the marriage or thereafter.(e) The right to petition for support or educational expenses, or both,  under Sections 505, 513, and 513.5 is not extinguished by the death of a parent.  Upon a petition filed before or after a parent's death, the court may award  sums of money out of the decedent's estate for the child's support or  educational expenses, or both, as equity may require.  The time within  which a claim may be filed against the estate of a decedent under Sections  505 and 513 and subsection (d) and this subsection shall be governed by the  provisions of the Probate Act of 1975, as a barrable, noncontingent claim.(f) A petition to modify or terminate child support  or the allocation of parental responsibilities, including parenting time, shall not delay any child support enforcement litigation or  supplementary proceeding on behalf of the obligee, including, but not limited  to, a petition for a rule to show cause, for non-wage garnishment, or for a  restraining order.
