How do I file for divorce in Thornton, Colorado?
To file for divorce in Thornton, you submit a Petition for Dissolution of Marriage (JDF 1101) to the Adams County District Court in Brighton, pay the $230 filing fee, and serve your spouse. At least one spouse must have lived in Colorado for 91 days first under C.R.S. § 14-10-106. Colorado is a no-fault state, so you only need to state the marriage is irretrievably broken.
Most Thornton filers complete the process in a predictable sequence:
- Confirm you meet the 91-day Colorado residency rule.
- Complete JDF 1101 (Petition) and JDF 1102 (Summons), available free from the Colorado Judicial Branch.
- File in person at 1100 Judicial Center Dr. in Brighton, or e-file through the Colorado courts portal.
- Pay the $230 petitioner fee, or request a waiver using JDF 205 and JDF 206 if your income qualifies.
- Serve your spouse, or have them sign a voluntary Waiver of Service to avoid the $50 to $75 process-server cost.
- Exchange financial disclosures (Sworn Financial Statement, JDF 1111) within 42 days.
Where do I file for divorce in Thornton? (which courthouse)
Thornton residents file at the Adams County Justice Center, 1100 Judicial Center Dr., Brighton, CO 80601, the district courthouse for the entire 17th Judicial District. The clerk's office phone is 303-654-3202, and the Self-Help Center for self-represented filers is reachable at 303-654-3213. Court hours are 7:30 a.m. to 4:00 p.m., Monday through Friday.
Thornton does not have its own district court for divorce. The city is roughly 15 to 20 minutes south of the Brighton courthouse via I-25 and E-470 or US-85, so plan your trip accordingly if you file paper documents in person. Non-attorneys can e-file domestic relations cases through the Colorado Judicial Branch electronic system, which eliminates the drive for many uncontested filers. If you receive a fee waiver, note that you cannot use e-filing because the $12 e-filing fee is non-waivable, so a waiver requires paper filing at the Brighton clerk's counter.
How much does a divorce lawyer cost in Thornton?
A Thornton divorce lawyer generally charges $250 to $400 per hour, with retainers commonly between $2,500 and $5,000. An uncontested divorce handled with limited attorney involvement often totals $1,500 to $3,500, while a contested case with custody and property disputes can reach $15,000 to $30,000 or more. The mandatory court filing fee of $230 is separate from attorney fees.
Costs in the Adams County market track the broader Denver-metro range. Factors that drive your bill up include disputes over parenting time, business valuations, retirement account division (QDROs), and the number of court hearings required. Many Thornton attorneys offer flat-fee packages for genuinely uncontested cases and unbundled (limited-scope) representation, where you hire a lawyer only for specific tasks like drafting a separation agreement or reviewing a parenting plan.

How long does a divorce take in Thornton?
The fastest a Thornton divorce can finalize is 91 days, because C.R.S. § 14-10-106(1)(a)(III) requires 91 days to pass after the court gains jurisdiction over the respondent before any decree is entered. Uncontested cases in Adams County typically conclude in 91 to 120 days. Contested divorces involving disputed parenting time or property often take 9 to 18 months.
The 91-day clock starts when your spouse is served or signs a waiver, not on the day you file. Two separate 91-day periods exist under Colorado law: one of residency before filing, and one of waiting after jurisdiction attaches. There is no exception, even for couples who agree on everything. Realistic timelines depend on how quickly both spouses complete financial disclosures and whether the Adams County court requires a status conference or sets the matter for a contested hearing.
What are the residency requirements to file in Adams County?
To file in Adams County, at least one spouse must have been domiciled in Colorado for 91 days immediately before filing, under C.R.S. § 14-10-106(1)(a)(I). Only one spouse needs to meet this rule, so you can file in Brighton even if your spouse lives out of state. Colorado's 91-day requirement is among the shortest in the nation.
Residency means legal domicile: physical presence in Colorado with intent to remain. Courts may ask for a Colorado driver's license, voter registration, a lease, utility bills, or employment records as proof. If minor children are involved, a separate and longer standard applies. Under the UCCJEA at C.R.S. § 14-13-201, Colorado courts gain jurisdiction over custody only when the child has lived in the state for at least 182 consecutive days before filing. Jurisdiction over the divorce itself cannot be waived or created by agreement, so genuine residency is essential.
How is property divided in a Thornton divorce?
Colorado is an equitable distribution state under C.R.S. § 14-10-113, meaning the Adams County court divides marital property in proportions it deems just, not automatically 50/50. Marital property includes nearly everything acquired during the marriage regardless of whose name is on the title. Gifts, inheritances, and pre-marriage property generally remain separate.
The court considers each spouse's contribution to acquiring the property (including as a homemaker), the value set apart to each spouse, and each spouse's economic circumstances when the division takes effect. Marital misconduct does not affect the split. Property is valued as of the date of the decree or the disposition hearing. Retirement accounts earned during the marriage are marital property and are commonly divided through a Qualified Domestic Relations Order. For child-related costs, our child support calculator reflects Colorado's income-shares formula.
Frequently Asked Questions
Do I need a divorce lawyer in Thornton, or can I file myself?
You are not required to hire a lawyer. The Adams County Self-Help Center (303-654-3213) assists self-represented filers, and JDF forms are free online. However, contested custody, retirement division, or business assets usually justify a Thornton divorce lawyer charging $250 to $400 per hour to protect your interests.
What is the filing fee for divorce in Adams County in 2026?
The petitioner pays $230 to file for dissolution of marriage in Adams County as of January 2026, plus a non-waivable $12 e-filing fee. A responding spouse pays $116 to file an answer. The fee increase took effect under Colorado House Bill 2024-1286. Income-qualified filers can request a waiver via JDF 205 and JDF 206.
Can I get the Adams County filing fee waived?
Yes. Colorado waives the $230 filing fee for petitioners whose household income falls at or below the eligibility threshold (roughly 125% of federal poverty guidelines), using JDF 205 and JDF 206. People receiving SNAP, SSI, TANF, or Medicaid may qualify automatically. The $12 e-filing fee cannot be waived, so approved filers must file on paper in Brighton.
Is Colorado a no-fault divorce state?
Yes. Colorado is a pure no-fault state under C.R.S. § 14-10-106. You only need to state that the marriage is irretrievably broken, and you cannot use fault grounds like adultery to obtain the divorce. Marital misconduct also does not affect property division under C.R.S. § 14-10-113.
How does custody work for Thornton parents?
Colorado uses the term allocation of parental responsibilities, not custody. Under C.R.S. § 14-10-124, the Adams County court decides parenting time and decision-making based on the best interests of the child, with the child's safety paramount. Courts encourage frequent contact with both parents and cannot presume either parent is better based on sex.
How far is the Brighton courthouse from Thornton?
The Adams County Justice Center at 1100 Judicial Center Dr., Brighton, is roughly 15 to 20 minutes north of central Thornton, depending on traffic and whether you take I-25, US-85, or E-470. Many uncontested Thornton filers avoid the trip entirely by using the Colorado Judicial Branch e-filing system for domestic relations cases.
What happens after I file for divorce in Thornton?
After filing, you serve your spouse, which starts the 91-day waiting period. Both spouses must exchange Sworn Financial Statements (JDF 1111) within 42 days. The court may set an initial status conference. Once disclosures are complete and 91 days pass, an uncontested case can finalize, often within 91 to 120 days in Adams County.
