Indiana Code 31-11-3, the Statute Behind Every Indiana Prenup
State prenup law comes from the Indiana Uniform Premarital Agreement Act, Indiana Code Chapter 31-11-3. The Act took effect July 1, 1995, and courts treat a premarital agreement as a contract governed by it.
A valid prenup must be in writing and signed by both parties, and the statute says it is enforceable without consideration. The table below summarizes the main rules, including signing, notarization, lawyers, child support, and amendment after marriage.
Is Indiana a 50/50 Divorce State?
The state is an equitable distribution state with a starting presumption that an equal division of marital property is just and reasonable. A spouse can rebut that presumption with evidence.
It also has a one-pot rule. Indiana Code 31-15-7-4(a) puts all property into the marital pot, including property owned before marriage, property acquired by either spouse before final separation, and property acquired through joint efforts.
Section 31-15-7-5 lists the evidence a court may use to move away from an equal division. The first factor is each spouse’s contribution to acquiring property, whether the contribution produced income or took another form.
A second factor is the extent to which property was acquired before marriage or through inheritance or gift. The third factor is the economic circumstances of each spouse, including whether the family residence should be awarded to the custodial parent.
Conduct related to disposition or dissipation of property is the fourth factor. The fifth factor is the earnings or earning ability of each spouse, which allows the court to consider income capacity when deciding what division is just and reasonable.
That one-pot rule is the reason premarital assets, gifts, and inheritances can matter so much here. Those assets enter the marital pot first, then a spouse can argue under the statutory factors that an equal division should change.
A prenup can set property rights before the divorce statute does its work. Under Section 31-11-3-5, parties may contract about rights in property whenever and wherever acquired, and about what happens to property on separation, divorce, death, or another event.
What Cannot Be in an Indiana Prenup?
An Indiana prenup cannot reduce a child’s right to support, settle custody against the child’s best interests, or include a term that breaks public policy or a criminal statute. Within those limits, IC 31-11-3-5 leaves wide room for property and maintenance terms.
A prenup can cover property rights, divorce outcomes, death-related transfers, maintenance, insurance benefits, and choice of law if the term does not violate public policy or a criminal statute. Indiana Code 31-11-3-5 is the main content section.
Property coverage is broad. The statute allows terms about rights and obligations in property of either or both parties whenever and wherever acquired, and about disposition of property on separation, divorce, death, or another event.
The child support limit is firm. Section 31-11-3-5 says a prenup cannot adversely affect a child’s right to support, and custody is decided based on best interests at the time.
Spousal maintenance can be modified or eliminated, subject to the hardship rule discussed below. A prenup can also require wills or trusts, address life insurance death benefits, and choose which state’s law governs.
Infidelity terms need care here. Hemingway v. Scott involved an unmarried couple, and the Indiana Court of Appeals enforced a property contract that required reconveyance if she cheated, while comparing it to a premarital agreement under Section 31-11-3-5.
Terms Indiana Lets You Set
- Define rights in property owned before marriage or acquired later
- Set how property will be divided on separation, divorce, death, or another event
- Modify or eliminate spousal maintenance, subject to the statutory hardship rule
- Require wills, trusts, or other estate planning steps
- Allocate life insurance death benefits
- Choose the law that will govern the agreement
Off Limits Under Indiana Law
- Adversely affect a child’s right to support
- Control custody contrary to the child’s best interests at the time
- Include a term that violates public policy
- Include a term that violates a criminal statute
Writing, Two Signatures and No Notary
A prenup here is valid only if it satisfies the statutory formalities and is not later defeated by a statutory challenge. The statute requires writing and both signatures, but it does not require consideration, notarization, or a lawyer.

What IC 31-11-3-4 Requires
Indiana Code 31-11-3-4 says a premarital agreement must be in writing and signed by both parties. The same section says the agreement is enforceable without consideration, so neither person has to pay or promise anything extra to make it binding.
The statute does not require notarization. A notarized signature can still help prove who signed and when, but the statutory formalities are writing and both signatures.

Lawyers Are Optional but Weighed
State law does not require each person to have a lawyer. Independent counsel is one factor courts weigh when a prenup is challenged, along with the economic terms and the conditions of signing.
Harrill v. Harrill shows the point. The Indiana Court of Appeals upheld an agreement even though the wife had no lawyer, because she had the draft in advance, was told she could hire counsel, signed over a week before the wedding, and obtained a requested change.
No License Wait, So Plan the Timing Yourself
Signing well before the wedding gives a cleaner record of voluntariness. State marriage licenses have no waiting period and are valid for 60 days from issue, so couples may want the prenup calendar to run separately from the license calendar.
Last-minute pressure can become evidence in a later challenge. Courts look at the conditions under which the agreement was made, including what the other person knew.
Two Grounds That Void an Indiana Prenup
A prenup gets thrown out if the person challenging it proves one of the statutory grounds in Indiana Code 31-11-3-8(a). The two grounds are lack of voluntary execution or unconscionability when the agreement was signed.
The burden is on the challenger. Section 31-11-3-8(c) also says unconscionability is decided by the court as a matter of law, so the judge decides that issue.
Financial disclosure has no separate test in the statute. That is different from the model Uniform Premarital Agreement Act, but financial disclosure can still matter because courts consider the signing conditions and the other party’s knowledge.
Rider v. Rider gives the state’s plain standard for unconscionability. A contract can fail if a gross disparity in bargaining power led the weaker party to sign unwillingly or without awareness of the terms, and the deal is one no sensible person would accept under normal conditions.
Courts consider whether both had independent counsel, the economic circumstances created by the agreement, and the conditions under which it was made. Fetters and Harrill show how those facts can point in different directions.
Section 31-11-3-10 also preserves equitable defenses that limit time, including laches and estoppel. In Fetters, the Indiana Court of Appeals held the wife was not barred by those defenses.
In our review of appellate prenup disputes, 92 U.S. appellate validity disputes from 2021 to 2025 produced 43 full enforcement outcomes and 18 full invalidations. The state had 3 premarital agreement decisions in that set, and the one validity challenge, Harrill, failed.
- An Indiana-licensed attorney for each partner
- $799 per attorney, paid on top of the $599 base price
- Not required by Indiana law, but courts weigh independent counsel

Rider, Fetters and Harrill: How Indiana Courts Ruled
Cases here turn on the facts surrounding signing and the terms being enforced. Rider set the unconscionability standard, Fetters voided an agreement, and Harrill upheld one after a voluntariness and unconscionability challenge.
The outcomes below split mainly on age, reading ability, counsel, timing, requested changes, and the parties’ knowledge. Hemingway is included because the Indiana Court of Appeals compared an unmarried couple’s property contract to a premarital agreement.
Maintenance Waivers and the Extreme Hardship Exception
A prenup can modify or waive spousal maintenance, but the divorce court has a statutory safety valve for extreme hardship. The starting point is that the state’s default maintenance law is narrow.
Indiana Code 31-15-7-2 allows maintenance in only three situations. Those are incapacity of a spouse, a custodial spouse’s need for help because of an incapacitated child, or rehabilitative maintenance for education or vocational training.
Rehabilitative maintenance is capped at three years from the final decree. The award is within the court’s discretion, as the Indiana Court of Appeals described in Guilford v. Guilford.
Section 31-11-3-5 allows spouses to modify or eliminate spousal maintenance in a premarital agreement. That means a prenup can set a different maintenance arrangement from the default divorce statute.
IC 31-11-3-8(b) limits a maintenance waiver in one setting. If the waiver causes extreme hardship under circumstances that were not reasonably foreseeable at signing, the court may order maintenance to the extent needed to avoid that hardship.
Remarriage and Home Equity in Indiana
Couples who have prior marriages, home equity, or premarital property often have concrete reasons to consider a prenup. The Census Bureau reports that 27.0 percent of ever-married Indiana residents age 15 and older have married two or more times, above the U.S. share.

That matters because a later marriage may come with children, retirement accounts, a house, or obligations from an earlier divorce. Under the state’s one-pot rule, property owned before the wedding still enters the marital pot unless an agreement changes the result.
The Census Bureau also reports that 87.8 percent of married-couple households in the state own their home, which makes home equity a common asset for couples to address before marriage.
Home values are lower here than the U.S. median, but home equity can still be the largest asset a couple has. Local couples also marry younger than the national median.

How Much Does a Prenup Cost in Indiana?
A prenup here can cost very different amounts depending on whether each person hires a lawyer, uses an online platform, or chooses both. Clio’s Legal Trends rate data lists the average in-state lawyer hourly rate at $291 and family law at $284 per hour.

As an illustration, 6 hours of family lawyer time at $284 per hour is $1,704 for one lawyer. Two separate lawyers would double that illustration before any extra negotiation, revisions, or meetings.
HelloPrenup lists its state couple package at $599, with optional attorney add-ons and higher attorney-signed packages. Our HelloPrenup review explains the platform in more detail, and the cost table below compares the listed options.
The online prices in the table are listed package prices, while lawyer bills depend on time, rate, and scope. Couples with complex property or a likely challenge may spend more time on review and negotiation.
| Route | Cost | What you get |
|---|---|---|
| Online prenup | $599 per couple | Flat price for both partners, written for Indiana's version of the uniform act, with a free consultation |
| Online prenup, attorney for each partner | $2,197 per couple | Each partner gets an Indiana attorney who reviews and signs off |
| Single attorney add-on | $799 per partner | Counsel for one partner, which Indiana courts count as a factor in a challenge |
| Hourly family lawyer | $284 per hour | Average Indiana family law rate. Illustration: six hours for each of two lawyers is $3,408 |
Building an Indiana Prenup Step by Step
Getting a prenup here is mainly a process of identifying property, choosing terms, allowing time, and signing a written agreement. The steps below track the statute and the facts courts have considered.
- Start with AssetsList property owned before marriage, debts, income, retirement accounts, business interests, inheritances, and expected gifts. The state’s one-pot rule makes premarital property relevant.
- Choose Property TermsDecide what stays separate, what becomes shared, and what happens on separation, divorce, death, or another event. Indiana Code 31-11-3-5 allows broad property terms.
- Address MaintenanceDecide whether spousal maintenance will be modified, limited, or waived. Courts can still order support in cases of unforeseeable extreme hardship.
- Share Financial InformationThe state has no separate disclosure test in its prenup statute, but knowledge still matters in court. Written schedules can create a clearer record.
- Review Before SigningAllow time for review and changes before the wedding. Harrill upheld an agreement where the draft came in advance and a requested change was added.
- Sign the AgreementThe state requires a written agreement signed by both parties. For online process details, see our guide to getting a prenup online.
Changing an Indiana Prenup Once You Are Married
A prenup can be changed after the wedding only by a written agreement signed by both spouses. Indiana Code 31-11-3-7 also allows revocation after marriage only through a written agreement signed by both.

Couples who want a new agreement after marriage may be looking at a postnuptial agreement instead. Our prenup vs. postnup guide covers when each one is signed.
Questions Indiana Couples Ask
Indiana couples ask most about the one-pot rule, lawyers and maintenance. Each answer below names the Indiana Code section or appeals case behind it.
Are prenups enforceable in Indiana?
Yes, Indiana courts enforce prenups that meet the statute and survive any challenge for voluntariness or unconscionability. Rider v. Rider says premarital agreements are valid contracts if entered freely, without fraud, duress, or misrepresentation, and if they are not unconscionable.
Can a prenup protect property I owned before marriage in Indiana?
Yes, in Indiana a prenup can define rights in property owned before marriage. This matters because the state’s one-pot rule puts premarital property into the marital pot before the court decides whether an equal split should change.
Do I need a lawyer for a prenup in Indiana?
No, Indiana law does not require a lawyer for a prenup. Independent counsel is still one fact courts may weigh if the agreement is later challenged, along with economic terms and signing conditions.
What is a wife entitled to in a divorce in Indiana?
Without a prenup, either spouse starts from a presumption that an equal split of the marital pot is just and reasonable, and that pot includes property owned before the wedding (IC 31-15-7-4 and 31-15-7-5). Maintenance is limited to incapacity, caring for an incapacitated child, or rehabilitative support of up to three years (IC 31-15-7-2).
Does a prenup protect you 100% in Indiana?
No agreement is challenge-proof. A court can refuse it if the challenger proves involuntary signing or unconscionability at signing, and it can order maintenance despite a waiver when the waiver causes extreme hardship nobody could reasonably foresee at signing (IC 31-11-3-8).
