Modifications of Parenting Plan, Alimony, or Child support

The movant seeking modification of time-sharing (custody) must show both that the circumstances have substantially, materially changed since the original custody determination and that the child’s best interests justify changing custody. Furthermore, the substantial change must be one that was not reasonably contemplated at the time of the original judgment.

The Florida Supreme Court noted that in order to justify disturbing a child custody award, the degree of change in the conditions and circumstances since the date of the previous decree must be of a substantial character.

The child support guidelines may provide the basis for proving a substantial change in circumstances upon which a modification of an existing order may be granted. However, the difference between the existing monthly obligation and the amount provided for under the guidelines shall be at least 15 percent or $50, whichever amount is greater, before the court may find that the guidelines provide a substantial change in circumstances.

When the parties enter into an agreement for payments for, or instead of, support, maintenance, or alimony, whether in connection with a proceeding for dissolution or separate maintenance or with any voluntary property settlement, or when a party is required by court order to make any payments, and the circumstances or the financial ability of either party changes or the child who is a beneficiary of an agreement or court order as described herein reaches majority after the execution of the agreement or the rendition of the order, either party may apply to the circuit court of the circuit in which the parties, or either of them, resided at the date of the execution of the agreement or reside at the date of the application, or in which the agreement was executed or in which the order was rendered, for an order decreasing or increasing the amount of support, maintenance, or alimony, and the court has jurisdiction to make orders as equity requires, with due regard to the changed circumstances or the financial ability of the parties or the child, decreasing, increasing, or confirming the amount of separate support, maintenance, or alimony provided for in the agreement or order. A finding that medical insurance is reasonably available or the child support guidelines schedule in s. 61.30 may constitute changed circumstances. Except as otherwise provided in s. 61.30(11)(c), the court may modify an order of support, maintenance, or alimony by increasing or decreasing the support, maintenance, or alimony retroactively to the date of the filing of the action or supplemental action for modification as equity requires, giving due regard to the changed circumstances or the financial ability of the parties or the child.

The court may reduce or terminate an award of alimony upon specific written findings by the court that since the granting of a divorce and the award of alimony a supportive relationship has existed between the obligee and a person with whom the obligee resides. On the issue of whether alimony should be reduced or terminated under this paragraph, the burden is on the obligor to prove by a preponderance of the evidence that a supportive relationship exists.

In determining whether an existing award of alimony should be reduced or terminated because of an alleged supportive relationship between an obligee and a person who is not related by consanguinity or affinity and with whom the obligee resides, the court shall elicit the nature and extent of the relationship in question. The court shall give consideration, without limitation, to circumstances.
