Yes, you can modify alimony and child support in Florida after divorce, but only if you can show that there’s been a real and significant change in your situation that makes it fair to change the original order.
Let’s get into how and why.
Divorce orders are supposed to give you a sense of stability, but the truth is that life rarely stays the same for long. Incomes shift, peoples health changes, kids grow up and circumstances change. Florida law gets this and recognises that you might need to change your alimony and child support arrangements in response.
The trouble is that the rules for changing orders are pretty strict and unless you can show that something pretty significant has changed since the order was first made the courts probably won’t budge.
To understand how this all works in 2026 you need to look at both the laws that govern this stuff and how judges apply them in practice.
The Rules for Changing Alimony or Child Support
In Florida, the courts only change alimony and child support orders if something pretty major has happened since the order was first made – something they call a “substantial change in circumstances”. This change has to be something that didn’t happen before the original order was made and it’s got to be pretty substantial.
Here are some examples of the kinds of things that have been accepted in the past as being big enough to warrant a change:
- Losing a job through no fault of your own
- Becoming seriously ill and unable to work
- Having a big increase in income
- Retiring in line with the state’s rules
- Having a change in the needs of your child
But the courts are pretty tough on this – a short-term dip in income or a temporary financial setback usually isn’t enough. You need to have some solid documentation to back up your claim.

Modifying Alimony in 2026
Over the years the law on alimony in Florida has got a bit tighter. Permanent alimony is no longer an option for new cases, and there are limits on how long you can be asked to pay alimony for. This has made the courts a bit more cautious when looking at requests for a change.
One of the main things they look at is whether you or your ex have moved into a new relationship that is pretty much the same as marriage. They look at things like whether you’re living together, sharing resources and being financially interdependent. Just being in a romantic relationship isn’t enough – it’s about the financial impact that counts.
Retirement is also another common reason for a change. The courts will look at whether it is reasonable for you to be retiring at that point in your life, taking into account your age, health and work history. If you retire early without a good reason, it can look a bit suspicious.
If you want to change your alimony or child support arrangements you need to file a new form called a Supplemental Petition for Modification. Just stopping payments, even if you have lost your job, can get you into trouble with the courts – they take non-payment very seriously.
The person asking for a change has got the burden of proof – they have got to show that there really is a good reason to change the original order.
Modifying Child Support
Child support costs are calculated using a formula. These calculations use statutory guidelines that take into account income, health insurance premiums, daycare costs, and time-sharing percentages.
If there is a large change in a parent’s income, child support can be modified. A typical guideline for this is a change of at least 15% or $50 more or less than the current amount, depending on the situation.
Modification of child support can also be made if:
- The child has new medical or educational requirements
- One of the parents moves, changing time-sharing arrangements
- The previous support amount was calculated using incorrect income information
Florida courts are known to be very child-centered when it comes to child support. The primary concern is to ensure that the child receives proper support, not to penalize either parent.

Timing Is Important
Filing for modification becomes effective as of the filing date, not the date the event occurred. People often assume that it will be effective on the date of loss. So if someone waits for months after losing their job to file, the time that passed could create a large arrears amount.
Judges do not back-date unpaid support obligations unless the required procedure has been followed promptly.
What Courts Will Not Modify
For example, property division is final and a lump-sum equitable distribution award cannot be revisited except in rare cases where there is fraud or new evidence.
Further, courts do not modify support based on voluntary underemployment. If an individual quits their job for no reason or intentionally reduces their employment so they do not have enough money to pay support, they usually will have their income “imputed.” Judges review an individual’s capacity to earn, not their current employment.
Good faith is important. Documentation is even more important.
Practical Considerations Prior To Filing
If you are thinking about filing for modification of your support, it is best to gather:
- Tax returns for the last two years
- Current pay stubs or termination letters from your employer
- Medical documentation that may pertain to your modification (if applicable).
- Evidence of your new living arrangements if applicable to your modification request.
Judges expect clear financial records. If you just provide vague information about hardship, your motion may not be successful.
It is usually in your best interest to get legal advice as a procedural mistake in filing a modification can significantly delay relief. If you file the wrong petition or do not provide enough proof, the length of time you have to maintain financial distress could increase significantly.
