A mother in Florida cannot cancel child support on her own, even if she is the one receiving it. Florida treats child support as a legal duty owed to the child rather than a payment between parents, so the obligation ends only when a judge signs an order ending it.1Florida Senate. Florida Code 61.13 – Support of Children; Parenting and Time-Sharing; Powers of Court A mother who wants payments to stop has to file a petition in the same court that entered the original order and convince the judge that ending support is appropriate. Until that happens, the existing order stays in force and the father is still legally on the hook.
Why a Mother’s Say-So Isn’t Enough
Florida Statute 61.13 gives the court continuing jurisdiction over every child support order after it is entered.1Florida Senate. Florida Code 61.13 – Support of Children; Parenting and Time-Sharing; Powers of Court That means the judge, not either parent, controls when payments stop. A verbal understanding between mom and dad has no legal effect on the order. Neither does a written agreement between them, unless a court incorporates it into a new order.
This matters because the enforcement machinery doesn’t know about private deals. If a mother tells the father to stop paying and he does, the Florida State Disbursement Unit keeps expecting payments, arrearages pile up on paper, and the state may begin enforcement against him for a debt both parents thought was closed. The only safe way to end payments is to get the order itself ended.
How a Mother Formally Ends the Support Order
The core document is the Supplemental Petition for Modification of Child Support, Florida Supreme Court Approved Family Law Form 12.905(b).2Florida Courts. Supplemental Petition for Modification of Child Support It is filed with the Clerk of the Circuit Court in the county where the original order was entered, using the original case number and the parties’ names exactly as they appear on that order. The petition has space to explain the reason the mother is asking the court to end the obligation.
If the father agrees, a joint motion signed by both parents tells the court the request is uncontested. Uncontested matters generally move faster because the judge doesn’t have to resolve a factual dispute between the parties.
Financial Affidavit
Every child support petition in Florida has to be filed with a sworn financial affidavit. Parents with gross annual income under $50,000 use the short form (12.902(b)); those at or above $50,000 use the long form (12.902(c)). The affidavit covers income, monthly expenses, assets, and debts, and it should be backed up with recent pay stubs or tax returns. Judges lean heavily on these numbers when deciding whether the child will still be financially secure after support ends, so sloppy or incomplete affidavits can sink the petition.
Filing Fees and Service
The filing fee for a supplemental modification petition is typically around $50, though related petitions can run up to $300. A mother who cannot afford the fee can apply for civil indigent status under Florida Statute 57.082 to request a waiver.3The Florida Legislature. Florida Statutes 57.082 – Determination of Civil Indigent Status If the petition isn’t a joint motion, the father has to be formally served by a sheriff’s deputy or a private process server, typically $40 to $100. Skipping service, or doing it incorrectly, gives the court grounds to dismiss the petition outright.
The Hearing
Once service is complete, the court sets a hearing. A judge or child support hearing officer reviews the petition, both financial affidavits, and any evidence either parent offers. The core question is whether the child’s best interests are protected. Uncontested hearings with clear financials can be brief, and simple modifications often finish within 30 to 60 days of filing. Contested matters take longer. Only when the signed order reaches the State Disbursement Unit does automated collection actually stop.
What the Judge Needs to See
Florida law lays out specific grounds that justify ending a support order. Outside of those, a judge usually won’t terminate.
Automatic End Points
For orders entered after October 1, 2010, Florida requires the obligation to terminate on the child’s 18th birthday, with two exceptions written into Florida Statute 743.07(2): the child is still in high school between 18 and 19 with a reasonable expectation of graduating before turning 19, or the child has a mental or physical incapacity that began before age 18.4Florida Senate. Florida Code 743.07 – Rights, Privileges, and Obligations of Persons 18 Years of Age or Older Support also ends if the child marries, joins the armed forces, or dies. Even when one of these triggers applies, the paying parent should file a motion to formally close the obligation rather than just stopping payments.
Substantial Change in Circumstances
To end or significantly reduce support before the child ages out, the law requires a substantial change in circumstances. Under Florida Statute 61.30, the difference between the current monthly obligation and what the guidelines would produce under the new facts must be at least 15 percent or $50, whichever is greater.5The Florida Legislature. Florida Statutes 61.30 – Child Support Guidelines; Deviation; Federal Tax Exemption The change also has to be permanent and involuntary.6Florida Department of Revenue. Changing Support Orders
Common scenarios a mother might present:
- The child has moved in full-time with the father, so the direction of support no longer matches reality.
- The parents have shifted to a roughly 50/50 time-sharing arrangement and both are covering the child’s expenses directly.
- The child has become self-supporting through full-time work and no longer depends on either parent financially. This is rare but possible.
Even when the facts clearly support ending the order, nothing changes until the judge reviews the evidence and signs the new order.
Ending the Order Doesn’t Erase Past-Due Support
This is the piece most parents miss. Stopping future payments and clearing out past-due support are two separate things. A mother can ask the court to end the ongoing obligation, but any arrearages that have already accumulated remain a legally enforceable debt until they are paid or the court formally waives them.
When the State Has Its Own Claim
If the mother’s household ever received public assistance, the state has an independent right to collect arrearages as reimbursement. The Florida Department of Revenue, acting as the Title IV-D agency, has broad authority to pursue those debts, and neither parent can sign them away.7Florida Senate. Florida Statutes 409.2557 – Title IV-D Agency; Powers, Duties, and Responsibilities Even if the mother wants to forgive everything the father owes, the state’s reimbursement claim survives.
Waiving Arrears Owed Only to the Mother
When no public assistance was involved and the past-due balance is owed entirely to the mother, she can file a waiver of arrears. The waiver has to state the exact dollar amount being forgiven, and it only takes effect once it is incorporated into a signed court order. A private note between parents will not stop the clerk from continuing to carry the debt or the state from continuing to enforce it.
Interest Keeps Running
Florida charges statutory interest on unpaid child support, calculated under Florida Statute 55.03 by averaging the Federal Reserve Bank of New York’s discount rate over the prior 12 months and adding four percentage points. The rate resets annually, and interest accrues on each missed payment individually. The longer arrears sit, the faster the balance compounds. Resolving them through payment or a court-approved waiver sooner rather than later keeps the number from growing.
What Happens If the Father Just Stops Paying
Florida does not wait for parents to work things out informally. As long as the order is active, state enforcement runs on its own against the father, even if the mother has told him to stop paying. Standard enforcement includes:
- Driver’s license suspension through the clerk or depository after notice.8The Florida Legislature. Florida Statutes 322.245 – Suspension of License Upon Failure to Pay Child Support
- Passport denial or revocation once past-due support exceeds $2,500.9Florida Department of Revenue. Passport Application Denial
- Income withholding directly from the father’s wages.
- Interception of federal and state tax refunds.
- Suspension of professional, hunting, and fishing licenses by the Department of Revenue.7Florida Senate. Florida Statutes 409.2557 – Title IV-D Agency; Powers, Duties, and Responsibilities
A mother who wants to actually end the father’s obligation protects both of them by going through the court. The informal route leaves him exposed to enforcement for a debt neither parent believes he still owes, and leaves her unable to collect later even if she changes her mind, because the arrears clock keeps running whether anyone is tracking it or not.
