Yes, you can file for divorce during pregnancy in Montana, and the court will process your case. Under MCA § 40-4-105, Montana law requires the divorce petition to disclose whether the wife is pregnant, but pregnancy does not prevent filing or finalizing a dissolution of marriage. Montana courts will address paternity, parenting plans, and child support as part of the divorce proceedings. The standard 21-day waiting period applies, and uncontested cases typically finalize in 30-60 days after filing. However, pregnancy does disqualify couples from using Montana's simplified Summary Dissolution procedure under MCA § 40-4-130.

Montana Law on Filing for Divorce While Pregnant
Montana permits divorce during pregnancy without restriction on when the case can be finalized. Under MCA § 40-4-105, the petition for dissolution must include the names, ages, and addresses of all living children of the marriage and must state whether the wife is pregnant. This disclosure requirement exists to ensure the court addresses custody, support, and paternity for the unborn child as part of the proceedings. Unlike some states that delay finalization until after birth, Montana courts will issue a final decree while the wife remains pregnant.
Montana is exclusively a no-fault divorce state under MCA § 40-4-104. The only ground for dissolution is irretrievable breakdown of the marriage, evidenced by either 180 days of living separate and apart or serious marital discord that adversely affects one or both parties. Courts cannot consider marital misconduct such as adultery when granting the divorce or dividing property.
Summary Dissolution Is Not Available When Pregnant
Pregnancy disqualifies couples from Montana's simplified Summary Dissolution procedure. Under MCA § 40-4-130, a marriage may only be dissolved through summary dissolution if the wife is not pregnant. This requirement applies regardless of other qualifying factors. Summary Dissolution is designed for couples with no children, limited assets (under $25,000 fair market value), minimal debt (under $8,000 unsecured), and mutual agreement to dissolve the marriage. Both parties must waive appeal rights and appear at a brief hearing approximately 20 days after filing.
When the wife is pregnant, couples must use the standard dissolution process instead. The standard process requires the filing of a Petition for Dissolution of Marriage, service on the respondent spouse, a 21-day response period, completion of a parenting plan, and a final hearing or decree by agreement. The standard process typically takes 60-120 days for uncontested cases and 6-18 months for contested matters.
Residency Requirements for Filing in Montana
At least one spouse must establish Montana domicile for a minimum of 90 days before filing for divorce. Under MCA § 40-4-104, Montana courts lack jurisdiction to hear a dissolution case unless this residency threshold is met. Military personnel stationed in Montana satisfy the residency requirement for both the service member and their spouse. The petition must be filed in the District Court of a county where venue is proper, typically where either spouse has lived for at least 90 days.
For cases involving children, Montana courts require an additional 6-month residency period for the children under MCA § 40-4-211 before exercising jurisdiction over custody and parenting matters. This provision applies under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA). If the pregnant wife has lived in Montana for 90 days but expects to deliver within 6 months of filing, the court may still proceed with the divorce while reserving jurisdiction over final custody matters.
Filing Fees and Court Costs in Montana
The divorce filing fee in Montana ranges from $170 to $250 depending on the county, composed of a base filing fee plus judgment fee as established by MCA § 25-1-201. Respondents who file an answer pay an additional $70 filing fee. Combined initial court costs total approximately $240-$320 when both parties participate. Additional costs include service of process fees ($30-$75), parenting education classes ($25-$75 per parent), and document certification fees ($5-$15). As of January 2026, verify exact fees with your local District Court clerk, as these amounts may change annually.
Fee waivers are available for low-income filers. Under Montana court rules, households at or below 125% of federal poverty guidelines ($23,531 for a single person or $48,188 for a family of four in 2026) may submit a Statement of Inability to Pay Court Costs and Fees. A District Court judge must approve the waiver before filing proceeds. Approximately 15-20% of dissolution filings in Montana receive full or partial fee waivers.
Paternity Presumption for Children Born During Marriage
When a child is born during the marriage or within 300 days after the marriage terminates, Montana law presumes the husband is the biological father. This presumption applies under MCA § 40-6-105 and the Uniform Parentage Act. The husband's name will appear on the birth certificate unless paternity is challenged through genetic testing and court adjudication. Both parents bear legal responsibility for child support regardless of biological paternity until the presumption is legally rebutted.
If the husband is not the biological father, he may challenge paternity during the divorce proceedings. Genetic testing (DNA test) can establish or disprove biological parentage with 99.9% accuracy. The court may order testing upon request by either party. If testing excludes the husband as the biological father, the court will not require him to pay child support, and no parenting plan will include him for that child. The biological father may then be identified and brought into the case for paternity establishment under MCA Title 40, Chapter 6.
Parenting Plans for Unborn Children in Montana
Montana requires a parenting plan for every dissolution involving children, including unborn children, under MCA § 40-4-234. The parenting plan establishes residential schedules, decision-making authority for education and healthcare, holiday and vacation schedules, and dispute resolution procedures. Montana courts use the term parenting rather than custody or visitation to emphasize both parents' ongoing involvement. The plan must serve the best interests of the child under the factors listed in MCA § 40-4-212.
When drafting a parenting plan for an unborn child, courts typically include provisions that become effective upon birth. Standard provisions address hospital visitation rights for the non-birthing parent, initial residential schedule for newborns (often with the birthing parent for the first 6-12 months due to breastfeeding considerations), gradual transition to shared parenting time, and modification procedures as the child's developmental needs change. Montana law assumes that both parents should have significant and frequent contact with the child unless such contact would harm the child.
Child Support Obligations During Pregnancy and After Birth
Montana calculates child support using the Income Shares model under MCA § 40-4-204 and Administrative Rules of Montana (ARM) 37.62.106. Both parents' monthly incomes are combined and cross-referenced against the state's guidelines table to determine a total child support obligation. Each parent then owes a share proportional to their percentage of combined income. A parent earning 60% of combined household income pays 60% of the guideline support amount.
The guidelines provide a personal allowance of $20,345 per year per parent, with minimum support percentage of 12% of income. For overnight parenting time exceeding 110 nights per year, the guidelines reduce the paying parent's obligation to account for direct childcare costs during those periods. Child support in Montana typically ranges from $250-$1,500 per month depending on parental incomes and the number of children.
Child support orders cannot take effect until the child is born. During the divorce proceedings involving a pregnant spouse, the court will typically calculate the anticipated support obligation and include it in the final decree as contingent upon birth. Support payments begin on the first day of the month following the child's birth. Either parent may request modification if circumstances change substantially after the initial order.
Property Division in Divorce During Pregnancy
Montana divides marital property using equitable distribution principles under MCA § 40-4-202. Equitable does not mean equal; courts aim for a fair division based on statutory factors including marriage duration, each spouse's age and health, earning capacity, contributions to the marital estate (including homemaker contributions), and custodial arrangements for children. Pregnancy and anticipated childcare responsibilities may influence the court's division as a factor affecting future earning capacity and financial needs.
All property acquired during the marriage by either spouse becomes marital property subject to division. Montana courts typically divide marital assets in the range of 40% to 60% per spouse, with exact percentages depending on the equitable factors. Separate property generally includes assets owned before marriage and gifts or inheritances received individually, though separate property can become marital property if funds are commingled. Courts cannot consider marital misconduct when dividing property.

| File Petition | Day 1 (after 90 days residency) |
| Serve Respondent | Days 1-14 |
| Response Deadline | 21 days after service |
| Mandatory Waiting Period | 21 days from filing |

Uncontested divorces during pregnancy can finalize as quickly as 30-60 days after filing if both parties agree on all terms and submit a complete parenting plan. Contested cases involving disputes over paternity, parenting arrangements, or property division may take 12-18 months to resolve through trial. The court may issue temporary orders for spousal maintenance, child support (to become effective upon birth), and exclusive use of the marital residence during the pendency of the case.
Health Insurance Considerations During Pregnant Divorce
Health insurance coverage for the pregnant spouse and unborn child requires careful planning during divorce. Under federal COBRA law, a spouse who loses coverage through the other spouse's employer-sponsored plan may elect continuation coverage for up to 36 months, though the covered individual must pay the full premium (typically $500-$1,500 per month) plus a 2% administrative fee. COBRA election must occur within 60 days of coverage loss.
Montana courts may order the employed spouse to maintain health insurance coverage for the pregnant spouse through delivery as part of temporary orders. The divorce decree should address insurance obligations including who provides coverage for the child after birth, allocation of unreimbursed medical expenses (typically 50/50 or proportional to income), COBRA premium responsibility during any gap period, and coordination of benefits if both parents have access to coverage.
Special Considerations: Military Families and Pregnancy Divorce
Military families face additional considerations when divorcing during pregnancy in Montana. The Servicemembers Civil Relief Act (SCRA) allows active-duty service members to request a stay (postponement) of civil proceedings for up to 90 days if military duties materially affect their ability to participate. This protection may delay the divorce timeline. Military pension division follows the Uniformed Services Former Spouses' Protection Act (USFSPA), which permits state courts to treat disposable retired pay as marital property. A spouse must have been married to the service member for at least 10 years overlapping with 10 years of creditable military service to receive direct payment from the Defense Finance and Accounting Service (DFAS).

The decree will include contingent provisions for child support and parenting that become effective upon the child's birth.
Can I use Summary Dissolution if I am pregnant in Montana?
No, pregnancy disqualifies couples from Montana's Summary Dissolution procedure. Under MCA § 40-4-130, one requirement for summary dissolution is that the wife is not pregnant.

How is child support calculated for an unborn child in Montana?
Montana uses the Income Shares model, combining both parents' incomes and referencing state guidelines tables. The typical range is $250-$1,500 per month depending on incomes and circumstances.

Pregnancy-related work limitations may support a maintenance request.
What happens if my husband is not the biological father?
The husband may challenge the paternity presumption by requesting genetic testing. If DNA testing excludes him as the biological father (99.9% accuracy), the court will not require child support from him and will not include him in the parenting plan for that child. The biological father may be identified and brought into the case for paternity establishment.
How long does divorce during pregnancy take in Montana?
Uncontested divorces typically finalize in 30-60 days after the 21-day mandatory waiting period. Contested cases involving disputes over paternity, custody, or property may take 12-18 months.

For an unborn child, the court will consider how relocation affects the anticipated parenting plan and the other parent's ability to participate in the child's life after birth.
