In most child custody cases, each parent pays their own court costs and attorney’s fees. That default comes from the American Rule, and it holds unless a judge decides to shift costs onto the other parent. Judges have broad discretion to do exactly that, and the two situations that most often trigger a shift are a wide income gap between the parents and bad-faith litigation conduct by one side.
Knowing when a court will deviate from the default, and how to ask it to, is what separates parents who get stuck with the full bill from those who don’t.
The Default: Each Parent Pays Their Own
Under the American Rule, each side in a lawsuit pays its own attorney’s fees. Custody cases follow the same principle. The reasoning is practical: if parents risked getting hit with the other side’s legal bill on top of their own, many would avoid court even when they had a legitimate reason to be there.
Court costs like filing fees and service charges work the same way. Each parent covers the costs tied to their own filings and motions. This holds unless a judge specifically orders otherwise.
When a Judge Orders One Parent to Pay the Other’s Costs
Family courts have broad authority to shift some or all of one parent’s expenses onto the other. They don’t do it casually. Two situations account for most fee-shifting orders.
A Significant Income Gap
This is where most fee-shifting orders come from. If one parent earns substantially more than the other, the lower-earning parent can ask the court to order the higher earner to contribute to their legal costs. A custody case shouldn’t turn on which parent can afford better representation. A stay-at-home parent facing a spouse who earns six figures would be at a severe disadvantage without some financial leveling.
Judges look at each parent’s income, assets, debts, and access to liquid funds when deciding whether to shift fees and how much. The amount varies. A judge might require the higher earner to pay a specific dollar amount toward the other parent’s retainer, cover a percentage of ongoing fees, or reimburse costs after the case ends. Partial contribution is more common than a full fee award.
Bad-Faith Litigation Conduct
Courts can also order a parent to pay the other side’s fees as a sanction. Filing motions with no real legal basis, repeatedly ignoring court orders, hiding assets during financial disclosure, or deliberately dragging out proceedings to drain the other parent’s resources are the kinds of conduct that provoke a fee-shifting order. The purpose is both punitive and compensatory: the misbehaving parent caused unnecessary expense, so they bear it.
Federal courts have explicit statutory authority to sanction parties or attorneys who “unreasonably and vexatiously” multiply proceedings, making them personally responsible for the excess costs their conduct generates.1Office of the Law Revision Counsel. 28 USC 1927 – Counsel’s Liability for Excessive Costs State family courts have comparable authority under their own rules. If the other parent is clearly running up your legal bill through frivolous tactics, document each instance and raise it with the judge.
Asking for Help While the Case Is Pending
You don’t have to wait until the case ends. Most family courts allow a “pendente lite” request, Latin for “while the case is pending.” This motion asks the judge to order the other parent to contribute to your attorney’s fees on a temporary basis so you can actually participate in the litigation as it unfolds.
Pendente lite fee orders matter most in cases where one parent controls most of the household income. Without interim relief, the lower-earning parent can be forced to represent themselves or accept a bad settlement simply because they ran out of money before trial. To request one, you file a motion explaining the income disparity, attach proof of both parents’ financial situations, and ask for a hearing. The judge will usually require both sides to submit pay stubs, tax returns, and bank statements before ruling.
An interim fee order carries the same legal weight as any other court order. A parent who ignores it risks a contempt finding, which can bring additional fines or other consequences.
Fee Waivers for Court Costs
If you can’t afford court filing fees, you can ask for a fee waiver. This covers court-imposed administrative fees: filing charges, service costs, and similar expenses. A fee waiver does not cover attorney’s fees, private mediation, or court-ordered fines.
Eligibility rules vary by jurisdiction, but most courts use income thresholds tied to the federal poverty guidelines. You may qualify if your household income falls below a set percentage of those guidelines, if you receive means-tested public benefits like food assistance or Medicaid, or if you can show that paying court fees would prevent you from meeting basic household needs. The application is a standardized form from the court clerk’s office or the court’s website, asking about your income, expenses, and household size. A judge reviews it, usually quickly, because the court recognizes that inability to pay shouldn’t shut someone out of the legal system. If your waiver is denied, you can usually request reconsideration or appeal.
If You Can’t Afford an Attorney
Fee waivers handle court costs. They don’t help with the bigger expense: paying for a lawyer. Two options fill that gap.
Legal Aid
Legal Services Corporation-funded organizations provide free civil legal help to low-income individuals, including in family law and custody matters. To qualify, household income generally must fall at or below 125% of the federal poverty guidelines. For 2026, that means a single person earning no more than $19,950, or a family of four earning no more than $41,250 in the contiguous 48 states. Eligibility can extend up to 200% of the poverty guidelines in certain situations, such as when unreimbursed medical expenses, disability-related costs, or other significant financial burdens reduce a household’s effective income.2eCFR. 45 CFR Part 1611 – Financial Eligibility
Demand for legal aid in family law cases far exceeds supply, so not everyone who qualifies gets full representation. Some programs offer limited-scope help instead: reviewing your documents, coaching you before a hearing, or representing you at a single critical proceeding rather than the full case. Your state or county bar association can point you toward local legal aid organizations.
Self-Representation
You are not required to have an attorney in a child custody case. Many parents handle their own, especially when the dispute is relatively straightforward or both sides are close to agreement. Courts increasingly provide self-help resources for unrepresented parents, including standardized forms, instructional guides, and in some jurisdictions, staff at a self-help center who can assist with paperwork. These resources won’t give you legal advice about strategy, but they can help you meet the procedural requirements.
Self-representation works best when you’re organized and the issues aren’t too complex. If the other parent has an attorney and you don’t, the playing field can tilt against you even when the judge tries to be fair. In that situation, a pendente lite fee request or legal aid becomes especially important.
How to Actually Ask the Court to Shift Costs
If you want the other parent to pay part of your legal costs, you have to formally ask. The court won’t order fee shifting on its own. The request goes in as a written motion explaining why you’re entitled to have the other parent cover some or all of your expenses, which usually means documenting the income gap or detailing the specific bad-faith conduct that generated unnecessary costs.
Attach supporting evidence. Financial affidavits showing each parent’s income, a breakdown of the fees you’ve incurred, and any documentation of misconduct all strengthen the request. After filing with the clerk and serving a copy on the other parent, the court schedules a hearing where both sides argue.
Timing matters. Requesting contributions early through a pendente lite motion gives you resources when you need them most. Waiting until the case is over to seek reimbursement is still possible, but by then you’ve already carried the full burden, and there’s no guarantee the judge will order repayment. If cost is a real concern, raise it sooner rather than later.
What’s Actually at Stake Financially
The dollar figures matter when you’re deciding whether to push for a fee contribution. A contested custody case can run anywhere from a few thousand dollars to well over $40,000 once attorney’s fees, evaluations, and related expenses are added up. Filing fees typically range from roughly $50 to $500, with additional charges for motions and certified copies. Service of process usually runs $30 to $75. Attorney’s fees are almost always the biggest line item: a cooperative negotiation might cost a few thousand per side, while a case that goes to trial with expert witnesses can push each parent’s bill into the tens of thousands.
Court-ordered custody evaluations typically cost $1,000 to $2,500 for a court-appointed evaluator and $10,000 to $15,000 or more for a private one. A guardian ad litem usually adds $1,000 to $3,500 or more. How those costs get split is up to the judge; many split them proportionally based on income. Private mediation runs $100 to $300 per hour, though state-funded programs often provide it free. Court-ordered parenting classes are modest, usually $25 to $100.
Across all of these line items, the same principle applies: the default is that each parent pays their own share, and the judge can rearrange that allocation when fairness or misconduct calls for it.
