New Hampshire authorized collaborative divorce through RSA 490-J, the New Hampshire Collaborative Law Act, signed into law on October 9, 2021. New Hampshire was the 21st state to adopt a collaborative law statute and the first in New England. In a collaborative divorce, both spouses and their specially trained attorneys sign a participation agreement promising to resolve the case outside court. The defining feature, codified at N.H. Rev. Stat. § 490-J:9, is the disqualification rule: if the process fails, both attorneys must withdraw and the parties hire new litigation counsel. This guide explains how collaborative divorce works in New Hampshire, what it costs, and when it is the right choice.

What Is Collaborative Divorce in New Hampshire?
Collaborative divorce in New Hampshire is a settlement-only process where both spouses retain separately trained collaborative attorneys and sign a participation agreement committing to resolve every issue without litigation, as authorized by RSA 490-J. The process replaces courtroom battles with a series of structured four-way meetings. Both lawyers are contractually disqualified from representing their clients in court if negotiations collapse, which aligns everyone's incentives toward settlement.
The New Hampshire Collaborative Law Act is modeled on the Uniform Collaborative Law Act but tailored to state practice. It establishes the legal scaffolding for the process: it defines collaborative law participation agreements, mandates open and cooperative exchange of information under RSA 490-J:10, requires domestic violence screening under RSA 490-J:13, and provides for court approval of resulting agreements under RSA 490-J:8. Because New Hampshire grants no-fault divorce on the ground of irreconcilable differences under RSA 458:7-a, neither spouse must prove wrongdoing, which makes the cooperative collaborative model a natural fit for the state's divorce framework.
Collaborative divorce differs fundamentally from a traditional contested case. In litigation, attorneys advocate adversarially, file motions, conduct formal discovery, and prepare for trial. In a collaborative case, the parties commit in writing to transparency and problem-solving. The court is involved only at the end to approve the final agreement and enter the divorce decree, not to decide contested issues.
How Does Collaborative Law Work Under RSA 490-J?
Under RSA 490-J, collaborative law begins when both parties sign a participation agreement and continues through a team-based negotiation process until the parties reach a settlement or the process terminates. The participation agreement must identify the matter, name the collaborative lawyers, describe the parties' intention to resolve the dispute, and include the disqualification provision required by the statute. Signing this agreement formally commences the collaborative law process.
New Hampshire's collaborative process uses a team approach that distinguishes it from simple lawyer-to-lawyer negotiation. The core team includes each spouse and their collaborative attorney. Many cases add neutral professionals: a divorce coach or mental health professional who facilitates communication and addresses parenting concerns, and a neutral financial professional who gathers and analyzes financial information so both spouses work from the same numbers. This team structure means specialists handle the issues they are best suited for, often reducing duplication and cost compared to each side hiring competing experts.
The work happens in a series of joint meetings, commonly called four-way meetings because both clients and both lawyers attend. Between meetings, the parties gather documents, complete financial disclosures, and consider options. RSA 490-J:10 obligates each party to make timely, full, and candid disclosure of information related to the collaborative matter and to update that information promptly. Because the entire model depends on honesty rather than adversarial discovery, this transparency mandate is central to the statute.
The Disqualification Rule: RSA 490-J:9 Explained
The disqualification rule under RSA 490-J:9 provides that if a collaborative case fails to settle, both collaborative attorneys, and every lawyer in their firms, are disqualified from representing the parties in any related court proceeding. This single provision is the structural heart of collaborative practice and the feature that most distinguishes it from mediation or cooperative settlement negotiation.
The practical effect is significant. If either spouse decides to take the dispute to court, both spouses must fire their current attorneys and retain new litigation counsel from the ground up. This creates a powerful financial and practical incentive for everyone, including the lawyers, to make the process work. The attorneys cannot profit by escalating to litigation, because the moment litigation begins they lose the client. The disqualification is imputed to the entire law firm, so a client cannot simply switch to a different attorney at the same firm to continue.
RSA 490-J:9 includes narrow exceptions. A collaborative lawyer may appear before a court to ask it to approve an agreement reached through the collaborative process, and a lawyer may seek or defend an emergency order to protect the health, safety, welfare, or interest of a party, a family member, or another person under RSA 490-J:7. Outside these limited situations, the disqualification is absolute. Couples considering collaborative divorce in New Hampshire should weigh this rule carefully, because the cost of process failure includes starting over with new counsel.
Collaborative Divorce vs. Mediation vs. Litigation in New Hampshire
Collaborative divorce, mediation, and litigation represent three distinct paths to a New Hampshire divorce, differing in cost, attorney roles, and the consequences of failure. Collaborative divorce typically costs $7,000 to $25,000 combined, mediation often runs $3,000 to $9,000, and contested litigation commonly exceeds $15,000 to $50,000 per spouse. Understanding the structural differences helps couples choose the right process.
| Feature | Collaborative Divorce | Mediation | Litigation |
|---|---|---|---|
| Governing law | RSA 490-J | Family Division rules | RSA 458 |
| Attorney role | Each spouse has own attorney throughout | Often unrepresented or limited counsel | Each spouse has own attorney |
| Neutral professional | Optional coach + financial neutral | One neutral mediator | None (judge decides) |
| If process fails | Both attorneys disqualified (RSA 490-J:9) | Parties keep their attorneys | Case proceeds to trial |
| Decision-maker | The parties | The parties | The judge |
| Typical cost | $7,000-$25,000 combined | $3,000-$9,000 | $15,000-$50,000+ per spouse |
| Privacy | High (confidential under RSA 490-J:11) | High | Low (public record) |
| Typical timeline | 3-9 months | 2-6 months | 9-24 months |
Mediation uses a single neutral mediator who helps the spouses negotiate but does not represent either of them; spouses often retain their own attorneys for advice and keep them regardless of outcome. Litigation places decisions in the hands of a New Hampshire Circuit Court Family Division judge after motions, formal discovery, and potentially a trial. Collaborative divorce sits between these: each spouse keeps an advocate, the process stays private, and the disqualification rule pushes hard toward settlement.
What Does Collaborative Divorce Cost in New Hampshire?
A collaborative divorce in New Hampshire typically costs between $7,000 and $25,000 in combined professional fees, plus a court filing fee of $250 without minor children or $282 with minor children as of March 2026. The total depends on case complexity, the number of neutral professionals involved, and how quickly the parties reach agreement. While more expensive than basic mediation, collaborative divorce usually costs far less than contested litigation, which can exceed $50,000 per spouse.
The filing fee is paid to the New Hampshire Circuit Court Family Division when the joint petition or complaint is filed. As of March 2026, the fee is $250 for cases without minor children and $282 for cases with minor children; an additional 3% surcharge applies to credit and debit card payments. As of March 2026, verify the current amount with your local court clerk, because court fees change periodically. Households at or below 125% of the federal poverty guidelines may request a fee waiver using Form NHJB-2064-F.
Professional fees make up the bulk of the cost. Each spouse pays their own collaborative attorney's hourly rate, which in New Hampshire commonly ranges from $250 to $450 per hour. Couples who add a divorce coach and a neutral financial professional share those costs, but using one neutral financial expert is typically cheaper than each side hiring a competing forensic accountant in litigation. Parties who choose collaborative practice or mediation generally spend less in legal fees than those whose cases proceed to a contested final hearing, and the process usually concludes faster than a case waiting on the court docket.
Residency and Filing Requirements for New Hampshire Divorce
New Hampshire requires that at least one spouse be domiciled in the state to file for divorce, with the specific residency duration determined by where each spouse lives under RSA 458:5. If both spouses are domiciled in New Hampshire, the petitioner may file immediately with no minimum residency period. If only the petitioner lives in New Hampshire but the other spouse can be personally served within the state, no waiting period applies either.
A one-year domicile requirement applies only in the narrower situation where the petitioner is the sole New Hampshire resident and the other spouse cannot be served with process inside the state. In that case, the petitioner must have been domiciled in New Hampshire for at least one year before filing. Domicile means living in New Hampshire with the intention to remain permanently or indefinitely; merely staying temporarily does not qualify. You do not need to have married in New Hampshire to file there.
New Hampshire imposes no mandatory waiting period or separation requirement before a divorce can be finalized. The state grants no-fault divorce on the ground of irreconcilable differences that have caused an irremediable breakdown of the marriage under RSA 458:7-a, and approximately 90% of New Hampshire divorces proceed on this no-fault ground. Couples can file while still living in the same residence. Although no statutory waiting period exists, court scheduling and any required parenting programs still control the practical timeline, so most uncontested cases finalize in two to three months once filed. Venue is set by the county where either party lives under RSA 458:9.
Property Division in a New Hampshire Collaborative Divorce
New Hampshire divides marital property using equitable distribution under RSA 458:16-a, with a statutory presumption that an equal 50/50 split is equitable unless one of 15 statutory factors justifies deviation. Unlike most equitable distribution states, New Hampshire applies an all-property approach: courts can divide any asset owned by either spouse, regardless of when or how it was acquired, including premarital property, inheritances, and gifts.
In a collaborative divorce, the parties negotiate property division themselves rather than asking a judge to apply these rules, but the statutory framework still informs what a fair outcome looks like. The statute defines property broadly to include all tangible and intangible assets: real estate, bank accounts, vested and non-vested pensions, retirement and savings plans, and, to the extent federal law permits, military retirement. A 2019 amendment effective January 1, 2023 added that tangible property includes animals, requiring settlement agreements to address pets' care and ownership with the animals' wellbeing in mind.
The collaborative process is well suited to property division because the neutral financial professional gathers and values assets transparently, and both spouses work from identical numbers. The 15 factors a court would consider, including the duration of the marriage, each spouse's contributions to the home and to the other's career, tax consequences, and the value of premarital or gifted property, give collaborative teams a shared vocabulary for crafting an equitable split. A 2025 New Hampshire Supreme Court decision confirmed that the all-property rule sweeps the entire value of retirement benefits, including portions earned before marriage, into the divisible estate, though courts still weigh when benefits were earned as a factor.
When Is Collaborative Divorce the Right Choice?
Collaborative divorce works best when both spouses are committed to an amicable, out-of-court resolution and value privacy, control, and a preserved relationship, especially co-parents who will interact for years. It is most effective for couples who can communicate respectfully, want to avoid the public record and unpredictability of litigation, and are willing to disclose financial information voluntarily. Roughly 90% of New Hampshire divorces are no-fault, and many of those couples are good candidates.
Collaborative divorce is well suited to cases involving children, where the team approach and divorce coach help parents craft durable parenting plans, and to cases with complex finances, where a single neutral financial professional can value a business or untangle retirement accounts more efficiently than dueling experts. Because the process stays confidential under RSA 490-J:11 and the parties control the outcome rather than a judge, business owners and high-net-worth couples often prefer it for the discretion it provides.
Collaborative divorce is not appropriate in every situation. Cases involving domestic violence require careful screening under RSA 490-J:13, and the power imbalance may make collaborative negotiation unsafe or unfair. Where one spouse is hiding assets, refuses to disclose information honestly, or is determined to litigate, the voluntary-disclosure foundation of collaborative practice breaks down. The disqualification rule of RSA 490-J:9 also means that if the process fails, both spouses must hire new attorneys, an added cost that makes collaborative divorce a poorer fit when the likelihood of settlement is low. Couples uncertain whether collaborative practice suits them should consult a trained New Hampshire collaborative attorney to evaluate their specific circumstances.
