Jacksonville divorce mistakes cost real money. The ones that reach trial can run $15,000 to $50,000 or more, with discovery disputes, late disclosures, and misread 2023 reforms driving most of the overrun.
Most of these mistakes are preventable. After 25 years handling family-law cases in Duval County, these ten come up again and again.

Florida is a no-fault divorce state. The ground used in virtually every case is that the marriage is “irretrievably broken” (F.S. § 61.052).[1] A spouse does not need to prove adultery, abandonment, or other fault for the divorce itself to be granted. Yet many Jacksonville residents still waste time and money trying to build a “case” against their spouse.
What this means practically: lengthy depositions about infidelity or blame are largely irrelevant to whether the divorce will be granted. However, conduct does matter for certain ancillary issues. Adultery can influence alimony determinations, and domestic violence directly affects custody outcomes under the 20 best-interest factors (F.S. § 61.13).
The key distinction: fault won’t stop a divorce from happening, but it can affect how assets, support, and parenting time are divided.
Both spouses are required to file mandatory financial affidavits within 45 days of service under Rule 12.285 of the Florida Family Law Rules of Procedure.[1] Deliberately concealing assets (whether by underreporting income, hiding bank accounts, or transferring property to friends) is one of the most costly mistakes in a Jacksonville divorce.
Florida courts take financial fraud seriously. Under F.S. § 61.075, if a spouse intentionally dissipates, wastes, or conceals marital assets after filing or within the 2 years before filing, the court can consider that under F.S. § 61.075(1)(i) and award a disproportionate share to the other spouse. Concealment can also result in contempt of court, sanctions, and perjury charges.
In my experience, hidden assets often surface during discovery through tax returns, bank subpoenas, business valuations, or forensic accounting. The penalty for getting caught far outweighs whatever you hoped to keep.
Screenshots of social media posts are now routinely admitted as evidence in Duval County family court proceedings.[1] Photos of expensive vacations, new purchases, or a new relationship can directly contradict financial affidavit claims and custody arguments.
Common social media mistakes that damage divorce cases:
The safest approach: assume everything you post will be printed, highlighted, and handed to the judge. If in doubt, don’t post it.
Effective July 1, 2023, Florida enacted two major family-law reforms: Ch. 2023-301 established a 50/50 time-sharing presumption, and SB 1416 (Ch. 2023-315) eliminated permanent alimony.[2] Many people, including some attorneys, are still operating under the old rules. This is one of the most expensive mistakes you can make in a 2025 or 2026 divorce.
What changed on custody: Florida now has a rebuttable presumption of 50/50 time-sharing under F.S. § 61.13(2)(c)1. The court starts with equal time, and a party seeking a different schedule must show by a preponderance of the evidence that equal time-sharing is not in the child’s best interests. Before July 2023, there was no presumption. Each case started from scratch.
What changed on alimony: Permanent alimony was eliminated. The remaining forms are bridge-the-gap (capped at 2 years under F.S. § 61.08(6)), rehabilitative (capped at 5 years under F.S. § 61.08(7)(c)), and durational, which is capped at the lesser of the obligee’s reasonable need or 35% of the difference between the parties’ net incomes (F.S. § 61.08(8)(c)).
Strategies that worked before July 2023 often don’t work now. If your attorney hasn’t adjusted their approach to these reforms, you could end up with a significantly worse outcome.
| Rule | Before July 1, 2023 | After July 1, 2023 (Ch. 2023-301 and Ch. 2023-315) |
|---|---|---|
| Time-sharing default | No presumption; each case started from scratch | Rebuttable presumption of 50/50 time-sharing (F.S. § 61.13(2)(c)1.) |
| Standard to rebut the presumption | Not applicable | Preponderance of the evidence |
| Permanent alimony | Available | Eliminated (F.S. § 61.08) |
| Bridge-the-gap alimony | No duration cap | Capped at 2 years (F.S. § 61.08(6)) |
| Rehabilitative alimony | No duration cap | Capped at 5 years (F.S. § 61.08(7)(c)) |
| Durational alimony amount | Discretionary | Lesser of obligee's reasonable need or 35% of the net-income difference (F.S. § 61.08(8)(c)) |

Divorce is emotionally exhausting, and the desire to “just get it over with” is understandable. But rushing through settlement negotiations, especially on complex issues like property division, retirement accounts, and parenting plans, often leads to outcomes you’ll regret for years.[1]
Common areas where rushing causes problems:
Take the time to get a clear financial picture before agreeing to anything. A few extra weeks of negotiation can save thousands in the long run.
Voluntarily leaving the marital home doesn’t mean you forfeit your property interest. Florida’s equitable distribution statute (F.S. § 61.075) doesn’t penalize you for moving out.[1] But moving out without a legal strategy can create problems on other fronts.
In custody cases, the parent who stays in the home with the children often establishes the status quo for time-sharing. Under the new 50/50 presumption, this matters less than it used to. But if you’ve been voluntarily away from the children for months, it can affect the court’s evaluation of the parenting plan.
Before moving out, discuss these questions with your attorney:
Using parenting time as a bargaining chip, such as saying “I’ll agree to more time if you give up the house,” is one of the fastest ways to damage your credibility in a Florida custody case.[1] Courts evaluate parental conduct throughout the divorce process, and judges in the Fourth Judicial Circuit take note when a parent weaponizes access to children.
Under F.S. § 61.13, one of the 20 best-interest factors is each parent’s willingness to facilitate a close and continuing relationship between the child and the other parent. Blocking phone calls, canceling visits, or making derogatory comments about the other parent all count against you.
The 2023 reform strengthened this principle: the 50/50 presumption means the court starts from a position of equal time. A parent who actively obstructs the other parent’s relationship with the child is working against both the law and their own case.
Florida courts may refer parties to mediation on contested family law issues under F.S. § 61.183, and in Duval County the Fourth Judicial Circuit routinely does so before scheduling trial.[3] Mediation isn’t optional. It’s mandatory. But the mistake isn’t just refusing to attend; it’s refusing to participate in good faith once you’re there.
Florida’s court-connected mediation program handled over 100,000 family-law mediations in fiscal year 2024-2025, with a settlement rate historically reported in the 70% to 80% range.[3] Mediation typically costs $1,000 to $3,000 per party, compared to $15,000 to $50,000+ for a contested trial. The math strongly favors negotiation.
Judges notice when one party obstructs mediation. It can influence fee-shifting decisions (the obstructing party may be ordered to pay the other side’s attorney fees) and color the judge’s overall impression of your reasonableness.
Mandatory financial affidavits are due within 45 days of service. Missing this deadline triggers a cascade of problems: the other side files a motion to compel, the judge orders compliance, and if you still don’t produce documents, you face sanctions and contempt.[1]
Every day of delay adds attorney fees on both sides. Discovery disputes are one of the top cost drivers in contested Jacksonville divorces, and most of them are completely avoidable.
What you need to gather early:
Start collecting these documents before you even file. Having them organized from day one saves time, money, and stress.

Florida allows self-representation (pro se), and for a truly simple uncontested divorce with no children and minimal assets, it can work. But for anything involving custody, significant property, alimony, or the 2023 reforms, going without an attorney is a risk most people can’t afford to take.[1]
The 2023 reforms alone make professional guidance essential. The 50/50 custody presumption, the alimony caps, and the new durational limits all require strategic planning that self-represented litigants typically don’t have the background to navigate.
Consider this: the cost of an attorney for an uncontested divorce in Jacksonville is typically $2,500–$5,000. The cost of fixing a bad settlement, through modification proceedings, appeals, or enforcement actions, can be $10,000–$30,000 or more.
Divorce is one of the biggest financial and emotional decisions you’ll ever make. The mistakes on this list aren’t hypothetical. I’ve seen every one of them cost Jacksonville families thousands of dollars and months of unnecessary court time.

One of the costliest mistakes is not accounting for Florida’s 2023 family law reforms. The 50/50 custody presumption (Ch. 2023-301) and the elimination of permanent alimony (SB 1416) changed how divorce cases are negotiated and decided. Strategies that worked before July 2023 often produce worse outcomes now.[2]
No. Both spouses must file mandatory financial affidavits under Rule 12.285. Deliberately concealing assets can result in the court awarding a disproportionate share to your spouse under F.S. § 61.075, plus contempt of court charges and sanctions. Hidden assets often surface during discovery.[1]
Moving out doesn’t forfeit your property rights under Florida’s equitable distribution law. However, it can affect custody dynamics. The parent who stays with the children often establishes the status quo. Talk to an attorney before making this decision, especially if children are involved.[1]
Yes. Under F.S. § 61.183, Florida courts may refer parties to mediation on contested family law issues, and in Duval County it is routinely ordered before trial. Florida’s court-connected program handled over 100,000 family-law mediations in FY 2024-2025 with a historically reported settlement rate in the 70% to 80% range. Mediation costs $1,000–$3,000 per party. Far less than trial.[3]
The Duval County filing fee is $409 plus $10 for a summons. Total costs range from $2,500–$5,000 for an uncontested divorce with attorney to $15,000–$50,000+ for a contested case going to trial. Attorney fees in Jacksonville typically run $260–$330 per hour.[4]
Yes. Screenshots of social media posts are routinely admitted as evidence in Duval County family court. Vacation photos, expensive purchases, new relationships, and negative comments about your spouse can all undermine your financial claims and custody arguments.[1]
You’ll need three years of tax returns, six months of bank statements, retirement account statements, current pay stubs, mortgage and property records, credit card statements, and business records if self-employed. Gathering these before filing saves time and reduces discovery disputes.[1]
Florida treats a 529 plan started and funded during the marriage as a marital asset under F.S. § 61.075.[1] The settlement or final judgment should name who controls the account going forward, how future contributions will be handled, and how withdrawals will be approved.
Many parenting plans in Duval County put the account in one parent’s name but require written consent from both before any non-qualified withdrawal. If both parents contributed before filing, the balance is generally divided or allocated as part of equitable distribution.
Yes. Florida’s collaborative law process (F.S. §§ 61.55 to 61.58, enacted by Ch. 2016-93, Laws of Florida, effective July 1, 2016) is a formal out-of-court option. It gives spouses a formal out-of-court process in which both parties, both lawyers, and any shared neutrals (financial, mental-health) sign an agreement to resolve the case without litigation.[1]
The process terminates if either party files a related court proceeding or discharges their collaborative attorney (F.S. § 61.57). Participation agreements commonly bar both collaborative attorneys from representing their clients in subsequent litigation, which creates a strong incentive to settle.
Collaborative divorce fits cases where both spouses want privacy, want to keep the result out of a public courtroom, and are willing to disclose fully from the start. It is not appropriate where there is domestic violence or where one spouse will not disclose honestly.
Yes. Liabilities incurred during the marriage are defined as marital under F.S. § 61.075(6)(a)1., and that generally includes debts you run up before the final judgment.[1] Opening a new credit card, taking a HELOC, or carrying a large balance on an existing joint account during the divorce can be divided between both spouses as part of equitable distribution.
If you need to borrow for an unavoidable expense, document the reason and tell your attorney before you sign. A documented, necessary debt is treated differently from one that looks like dissipation.
