The different types of divorce in the United States fall into a few overlapping categories: no-fault or fault-based (depending on whether you blame your spouse), uncontested or contested (depending on whether you agree on the terms), and streamlined options like summary dissolution and default judgment. Mediation and collaborative divorce are two negotiated routes that can lead to any of those filings. Which path fits depends on how much you and your spouse agree on, how complicated your finances are, and what your state allows.
No-Fault Divorce
No-fault divorce lets you end a marriage without proving your spouse did anything wrong. You tell the court the marriage is irretrievably broken or that you have irreconcilable differences, and that is enough. The exact language varies by state, but the idea is the same everywhere: neither spouse has to be the “bad guy” for a judge to grant the divorce.
Every state now recognizes some form of no-fault divorce. Several have gone further and adopted pure no-fault systems, meaning fault grounds have been eliminated entirely and are no longer an option even if you want them. The shift began in the 1970s and reshaped family law across the country, making divorce faster, cheaper, and less adversarial for most couples.
This is by far the most common path. It avoids the cost and emotional toll of proving misconduct in court, and most couples who agree on the major issues and simply want to move on will file no-fault.
Fault-Based Divorce
Fault-based divorce requires you to prove that your spouse’s misconduct caused the marriage to fail. Roughly 33 states still allow fault filings alongside no-fault options. Grounds vary but commonly include adultery, cruelty (physical or severe emotional abuse), desertion or abandonment, and imprisonment for a significant period. Some states also recognize substance abuse, incurable mental illness, or inability to consummate the marriage.
Why take the harder path? In states that permit it, proving misconduct can influence how a judge divides property or awards alimony. A spouse who shows adultery or cruelty may receive a larger share of marital assets or more favorable support. That financial leverage is the main reason fault divorce still exists as an option. The trade-off is a longer, more expensive case that demands evidence: witness testimony, financial records, documentation of the conduct.
Fault filings have declined sharply since no-fault became universally available. Courts and attorneys generally treat them as worthwhile only when the misconduct was serious enough to meaningfully affect the financial outcome.
Uncontested Divorce
An uncontested divorce means you and your spouse agree on every major issue before the court gets involved: property and debt division, custody, child support, and alimony. Because there is nothing for the judge to decide, the process is streamlined, and many uncontested divorces finalize with minimal court appearances or entirely through paperwork.
This is typically the fastest and cheapest route. Court filing fees generally run from about $100 to $400 depending on where you live, and legal costs stay low because there is no need for extensive attorney involvement. Some couples handle an uncontested divorce without hiring lawyers at all, though having one review the settlement agreement is usually smart, especially when children or significant assets are in play.
The advantage is control: you and your spouse decide the terms rather than leaving them to a judge who knows nothing about your family. The limitation is obvious. It only works if you reach full agreement. If even one issue stays unresolved, the case becomes contested.
Contested Divorce
A contested divorce happens when you and your spouse cannot agree on at least one significant issue. The disagreement might be over who keeps the house, how retirement accounts get split, where the children will live, or how much support is appropriate. When negotiation stalls, the court decides.
Contested cases follow a formal litigation track. After one spouse files and the other responds, both sides enter discovery, exchanging financial and personal information under oath to prevent either side from hiding assets or misrepresenting their situation. Most courts then push the parties toward settlement through mediation or judicial conferences. If those efforts fail, the case goes to trial, where a judge hears testimony, reviews evidence, and issues a ruling.
Costs escalate quickly here. Between attorney fees, expert witnesses, and multiple court appearances, a contested divorce can cost tens of thousands of dollars and drag on for a year or more. The emotional toll tends to be equally steep, particularly when children are caught in the middle.
Summary or Simplified Divorce
Summary divorce, sometimes called simplified dissolution, is a streamlined option for couples whose situations are genuinely uncomplicated. Not every state offers it, and the eligibility rules are strict. The specifics differ by jurisdiction, but you typically need to meet all of the following:
- A short marriage, usually five years or less.
- No minor children born or adopted during the marriage, and neither spouse pregnant.
- Limited assets and debts, with a total value below a state-set dollar threshold.
- No jointly owned real estate (many states exclude couples who own a home together).
- Both spouses agreeing to waive alimony entirely.
If you qualify, the paperwork is simpler, you may not need to appear in court, and the process wraps up faster than a standard divorce. Summary divorce exists because the court system recognizes that a two-year marriage with a shared apartment and a joint checking account does not need the same legal machinery as a 20-year marriage with children, retirement accounts, and a family business.
Default Divorce
A default divorce happens when one spouse files, properly serves the other, and the other never responds. After a set period, which in most states falls between 20 and 30 days, the filing spouse can ask the court for a default judgment. The court then proceeds without the non-responding spouse’s input and generally grants the terms laid out in the original petition, including property division, custody, and support.
The practical takeaway: one spouse cannot block a divorce by refusing to participate. As long as you follow proper service procedures and give your spouse the required time to respond, the case moves forward. Courts still review the proposed terms to make sure they are reasonable, especially when children are involved, but the responding spouse gives up the ability to negotiate or object by staying silent.
Mediation Divorce
Mediation uses a neutral third party to help you and your spouse negotiate an agreement without going to court. The mediator does not take sides and does not make decisions for you. They guide the conversation, identify where you agree and disagree, explain the legal framework so both sides can make informed choices, and work toward compromises that address each person’s priorities.
The process moves through several stages: an initial session to set ground rules and identify issues, information gathering where both sides disclose finances, negotiation where the mediator helps brainstorm solutions, and a final drafting stage. If mediation succeeds, the resulting settlement is submitted to the court for approval as part of an uncontested filing.
Mediation tends to cost significantly less than litigation and offers more privacy, since negotiations happen outside the courtroom. It also tends to produce outcomes both sides can live with, because both sides shaped them. The catch is that mediation requires good faith and relatively equal bargaining power. It is generally not appropriate when domestic violence, financial abuse, or hidden assets are involved, because one spouse may be unable to advocate effectively.
Collaborative Divorce
Collaborative divorce is a more structured alternative to mediation. Each spouse hires their own attorney, but everyone signs an agreement at the outset committing to resolve the case through negotiation rather than litigation. The team often includes not only lawyers but also financial specialists, child specialists, and divorce coaches who help manage the emotional side.
The defining feature, and the biggest gamble, is the disqualification clause. If the collaborative process breaks down and either spouse decides to go to court, both attorneys must withdraw from the case. You would need to start over with new lawyers who were not part of the negotiations. That rule creates a strong incentive to stay at the table, but it also means you are betting your legal fees on the process working. If it fails, you have paid for two rounds of attorneys.
When it works, collaborative divorce produces thorough agreements that account for financial complexity, tax consequences, and parenting arrangements in ways a judge issuing a ruling after a two-day trial often cannot. It works best for couples who can still communicate, want to preserve a co-parenting relationship, and have enough assets to justify the upfront investment in professional support.
Legal Separation Is Not the Same Thing
Legal separation isn’t technically a type of divorce, but many couples weigh it alongside their divorce options, so it is worth flagging. In a legal separation, you and your spouse formalize living arrangements, divide finances, and establish custody terms through the court, but you remain legally married. Neither spouse can remarry.
Reasons couples choose it over divorce include keeping a spouse on an employer-sponsored health plan that divorce would end, honoring religious beliefs that discourage divorce, preserving eligibility for certain military or Social Security benefits that require a marriage to last a minimum number of years, and leaving the door open to reconciliation. Not every state recognizes legal separation, so check whether it is available where you live before planning around it.
How to Choose Between Them
Two questions drive the choice. First, how much do you and your spouse agree on? Full agreement points toward an uncontested filing, likely no-fault, possibly summary if you qualify. Partial agreement points toward mediation or collaborative divorce as a way to close the remaining gaps. No agreement, or an unwilling spouse, points toward contested litigation or, if your spouse refuses to engage at all, a default judgment.
Second, what are you willing to spend in money and time? Court filing fees for the initial petition typically run from about $100 to over $400. Mediators generally charge between $200 and $1,000 per hour. Collaborative divorce adds two attorneys plus any specialists. A contested divorce that goes to trial can generate five or six figures in combined legal fees. The type of divorce you pursue is the single biggest factor in what the process ultimately costs, and in how long you wait before you can move on.
