Divorce is not a particularly happy subject, but it’s something that many people will have to deal with at some point. The end of a marriage, though, needn’t mean the end of financial security for anyone. If you review the laws in your state and make sure you follow the required steps, you can come out of the other side of a divorce ready to reach your financial goals. Each state’s laws are different, though, so this guide will cover the major rules and regulations in Idaho.
For help navigating a divorce, planning for retirement or building an estate plan, consider working with a financial advisor.
How to File for Divorce in Idaho
Before you can file for divorce, you have to make sure that you are eligible to do so in the state. The residency requirement in Idaho is among the shortest in the country. One spouse must have lived in the state for just six weeks to qualify to file for an Idaho divorce.
Grounds for Divorce in Idaho
Idaho has both fault-based and no-fault divorce. For no-fault splits, no specific reason must be proved. Instead, one only needs to claim irreconcilable differences. For fault-based divorces, acceptable grounds include adultery, extreme cruelty, willful desertion of at least one year, willful neglect, habitual drunkenness for at least a year, living separately for at least five years, a felony conviction and one spouse being a resident in a mental institution for at least three years.
Process to Divorce
The first step for a divorce in Idaho is to file documents in the county in which you live. The exact documents you need will depend on where you live, so check with your county clerk to get the exact rundown for your locale. Generally, though, there will be an information sheet, a petition for divorce, a summons, an affidavit of services and a vital statistics form. If you have children from the marriage, there will be more forms.
Once everything has been filed, the other spouse must be served. This can be done by a third party, a sheriff or a process server. The other spouse will then respond to the court.
If both parties agree on major issues in the divorce, including division of assets, grounds for divorce, child custody and alimony or possible obligations to help with college expenses, an uncontested divorce can be obtained. You’ll present an agreement to the court and, if up to snuff, it will be approved by the judge.
If there are disagreements, though, you cannot have an uncontested divorce. Following service of divorce papers, there will be a discovery process where financial disclosures are made, evidence is gathered and witnesses are interviewed. The spouses may work with a mediator to try to agree, but if one cannot be reached, a trial will be scheduled. The judge will handle your case in this situation.
How to Split Up Assets During a Divorce in Idaho

Any property obtained during the marriage – including cash and physical assets – are considered marital property. The only exception is if something was obtained as a gift or inheritance.
Anything obtained before the marriage is considered separate property. However, if a piece of separate property generates income, it is considered marital property. For instance, let’s say one spouse owned an apartment before the marriage and rents it during the union. The apartment is considered separate property, but rent money collected while married is marital property.
How to Divide Property in Idaho After a Divorce
Idaho follows community property laws when dividing assets after divorce. This means that most property and debts acquired during the marriage are considered jointly owned by both spouses, regardless of whose name is on the title. When couples divorce in Idaho, these community assets are typically divided equally between the spouses. However, property owned before marriage or received as gifts or inheritance generally remains separate property.
The first step in property division is determining what qualifies as community property versus separate property. Community property includes income earned during marriage, homes purchased together, retirement accounts funded during marriage, and other assets acquired while married. Separate property includes assets owned before marriage, inheritances and gifts specifically given to one spouse. Keeping clear documentation of separate property is crucial to maintaining its status during divorce proceedings.
While Idaho law presumes an equal split of community property, courts may consider several factors when determining what’s truly equitable. These factors include the duration of the marriage, each spouse’s age and health, occupation and employability and the needs of any dependent children. The court aims to achieve a fair division that allows both parties to move forward financially after divorce.
Dividing complex assets like businesses, retirement accounts and investment portfolios requires careful consideration. Business valuations may be necessary to determine fair market value. Retirement accounts often require specialized court orders called Qualified Domestic Relations Orders (QDROs) to divide benefits without triggering tax penalties. Investment properties might need to be sold or one spouse may buy out the other’s interest.
How to Manage Child Support and Alimony Under Idaho Divorce Laws
Idaho uses the “income shares model” to determine child support payments. The judge estimates how much the parents would have spent on the child if they were still together and divides that based on how much money each parent makes. There is a fairly complicated process to determine exactly how much each parent owes, but income is the baseline. Projected custody time also impacts the final child support numbers.
Alimony, on the other hand, has no strict formula, as judges use a number of factors to figure out alimony payments. These include financial resources, the time it will take a supported staff to become self-supporting, the length of the marriage, physical and emotional health, tax consequences and marital misconduct of either spouse.
There are three types of alimony: temporary, fixed-duration and permanent. Here’s how they work:
- Temporary alimony: This only lasts throughout the trial.
- Fixed-duration alimony: This lasts a predetermined amount of time to give the supported spouse time to get the training or education needed to become self-sufficient.
- Permanent support: This type of alimony is rare, only being awarded in cases where one party can’t work due to age or disability. This support ends when the supported spouse dies or remarries.
401(k) and IRA and Divorce in Idaho
If money were put into a retirement plan, such as a 401(k) or IRA, during a marriage, those dollars are considered marital property. As such, they may be split up during a divorce proceeding. Normally, taking money out of a retirement plan before age 59.5 would result in a 10% penalty. However, the judge will issue a QDRO, which will waive these penalties.
After the money is taken out, you’ll have a few options. The distributions can be given directly to the relevant spouse, in which case, it would count as normal income and be subject to income tax. It can also be rolled over into a new retirement account. The judge may order exactly what is to be done with the money or it may be up to the person receiving the money.
For an IRA, a QDRO is not needed. Instead, the judge will write into the separation agreement exactly what is to be done with the money, allowing the penalties to be waived. Retirement plans are some of the most difficult parts of a marital estate to split up, so speak with financial advisor to make sure everything is taken care of.
Divorce and Estate Planning in Idaho

If you and your spouse have an estate plan, now is the time to revisit it. First off, your assets were likely set to go to your now ex-spouse after your death, and you may want to change that. If you want your assets to pass to your children, you’ll need to form a trust. You’ll also want to change the designated inheritor on any financial accounts you have, including retirement accounts.
If you have advanced directives or powers of attorney set up, you’ll need to change them unless you want your ex-spouse to make medical decisions for you. Finally, think about your children. If you have plans for what happens if you and your spouse both die, make sure it still applies.
Bottom Line
Idaho’s divorce laws provide a clear framework for couples ending their marriage in the Gem State. Whether you’re considering a divorce or already in the process, knowing the state’s specific requirements can help you prepare for what lies ahead. Idaho offers both no-fault and fault-based grounds for divorce, with a relatively short 6-week residency requirement that makes the process accessible to newer residents. The state’s community property approach means that marital assets are typically divided equally, though judges have discretion to ensure fairness.
