A prenuptial agreement is a written contract that two people sign before they marry. It sets out how property, debt, and financial support will be handled if the marriage ends in divorce or death.

Indiana has adopted the Uniform Premarital Agreement Act, found at Indiana Code Chapter 31-11-3. This law tells couples and courts what a prenup may cover and when a judge will enforce one.
This article walks through the rules that apply in Indiana, what an agreement can and cannot do, and what a typical prenup costs.
Are Prenuptial Agreements Enforceable in Indiana?
Yes. Indiana courts enforce prenuptial agreements that meet the standards set by Indiana Code 31-11-3. A valid agreement is treated as a binding contract.
The law is written to favor enforcement. A judge will hold a couple to their agreement unless the person fighting it proves one of the specific defenses listed in the statute.
The Two Ways a Prenup Can Fail
Under Indiana Code 31-11-3-8, an agreement is not enforceable if the person challenging it proves either of two things. The first is that the party did not sign the agreement voluntarily.
The second is that the agreement was unconscionable when it was signed. This second path has extra requirements that must all be met.
To void an agreement as unconscionable, the challenger must show that before signing, they were not given a fair and reasonable disclosure of the other person’s property and debts. They must also show they did not voluntarily and expressly waive that disclosure in writing, and that they did not have, and could not reasonably have had, adequate knowledge of those finances.
Who Carries the Burden of Proof
The burden falls on the spouse who wants to throw out the agreement. The person seeking enforcement does not have to prove the contract was fair.
This is a high bar to clear. A spouse who signed a one-sided deal but received honest financial disclosure usually cannot escape it under Indiana law.
Indiana Is a One-Pot State
Indiana follows equitable distribution, which means a divorce court divides property in a way it considers fair rather than automatically splitting everything in half. What sets Indiana apart is the one-pot rule.
Under Indiana Code 31-15-7-4, all property owned by either spouse goes into a single marital pot before division. This includes property that one spouse owned before the wedding, gifts, and inheritances.
The court starts with a presumption that an equal split of that pot is fair. A spouse can argue for an unequal division, but they have to prove it.
This default is why a prenup matters so much in Indiana. Without one, the house you bought years before the marriage or the retirement account you funded alone is fair game in court.
A prenuptial agreement lets a couple pull specific assets out of the pot and decide in advance who keeps them. It replaces the court’s guesswork with terms the two of you chose.
What an Indiana Prenup Can Cover
Indiana Code 31-11-3-5 lists the matters a couple may put in a premarital agreement. The range is wide and covers most financial questions a marriage can raise.
| Topic | What the agreement can do |
|---|---|
| Separate property | Define which assets stay one spouse’s own property, whenever or wherever acquired |
| Property division at divorce | Set how assets are split if the marriage ends in dissolution or legal separation |
| Property at death | State who receives property when one spouse dies |
| Debt | Assign responsibility for debts each person brings in or takes on later |
| Managing assets | Decide how each spouse may buy, sell, or control property during the marriage |
| Spousal maintenance | Modify or waive the right to spousal maintenance after divorce |
| Life insurance | Require a spouse to name the other as a beneficiary on a policy |
| Wills and estate plans | Require either spouse to make arrangements that carry out the agreement |
What You Cannot Put in an Indiana Prenup
The statute also sets clear limits. A court will strike provisions that cross these lines while still enforcing the rest of the agreement.
- It cannot limit or waive child support, because Indiana Code 31-11-3-5 says the agreement may not adversely affect a child’s right to support.
- It cannot decide child custody or parenting time, since a court rules on those based on the child’s best interests at the time.
- It cannot include terms that break the law or that a court finds against public policy.
- It cannot force personal, non-financial duties, such as rules about chores or appearance.
Execution Rules for an Indiana Prenup
Indiana keeps the signing rules simple. Getting them right is what makes the contract hold up later.
Writing and Signatures
Under Indiana Code 31-11-3-4, a premarital agreement must be in writing and signed by both parties. An oral promise between an engaged couple is not a valid prenup.
The agreement takes effect on marriage. If the wedding never happens, the agreement has no force.
No Consideration Required
Indiana Code 31-11-3-4 also states the agreement is enforceable without consideration. Neither person has to give the other money or anything of value to make the contract binding.
The marriage itself supports the agreement. The same rule applies if the couple later amends or revokes the prenup, which must also be done in a signed writing.
Spousal Maintenance in an Indiana Prenup
A couple may modify or eliminate spousal maintenance in their agreement under Indiana Code 31-11-3-5. This is a common reason people sign a prenup, since it sets expectations about support before any conflict arises.
Indiana Code 31-11-3-8 adds one safety valve. If a maintenance waiver causes one spouse extreme hardship under circumstances that were not reasonably foreseeable when the agreement was signed, a court may order maintenance despite the waiver.
That order is limited to the amount needed to relieve the hardship. The protection exists so that a waiver does not leave one spouse with no means of support after an unexpected turn of events.
The Role of Full Disclosure in Indiana
Disclosure is the single most important step in making an Indiana prenup stick. The unconscionability defense in Indiana Code 31-11-3-8 turns directly on whether each person knew what the other owned and owed.
Each partner should give the other a written list of assets, income, and debts before signing. Attaching these schedules to the agreement creates a clear record.
If a spouse later claims they were kept in the dark, the signed disclosure is the best evidence against that claim. Honest numbers up front protect the whole agreement.
Common Reasons Indiana Prenups Fail
Most failed prenups share a few avoidable problems. Watching for these keeps an agreement on solid ground.
- One spouse hid or understated assets, opening the door to an unconscionability challenge.
- The agreement was presented days before the wedding, which can support a claim that it was not signed voluntarily.
- The document was never put in writing or was missing a signature, violating Indiana Code 31-11-3-4.
- The agreement tried to limit child support or set custody, terms the statute does not allow.
- One spouse felt pressured or threatened, which undercuts voluntary consent.
- Neither party had a chance to review the terms with their own attorney.
How Much Does a Prenup Cost in Indiana?
Cost depends on how complicated your finances are and whether each person hires a separate lawyer. The ranges below reflect what Indiana couples typically pay.
| Option | Typical cost |
|---|---|
| Simple agreement, attorney drafted | $1,500 to $5,000 per couple |
| Complex or high-asset agreement | $2,000 to $7,000 per person |
| Online prenup platform | A few hundred dollars, flat |
Online services such as HelloPrenup let couples build an agreement for a flat fee that is far lower than hourly legal rates. Many couples use one of these platforms to draft the document and then pay a lawyer a smaller fee to review it.
Steps to Getting an Indiana Prenup
The process is straightforward when you take it in order. Starting early gives both people time to read and reflect.
- Begin well before the wedding so no one feels rushed into signing.
- Each partner gathers a full list of assets, income, and debts.
- Exchange those financial disclosures in writing and keep copies.
- Agree on the terms, including any treatment of separate property and spousal maintenance.
- Put the agreement in writing and have both people sign it.
- Have each partner review the agreement with their own attorney before signing.
- Store the signed agreement with your important records.
Final Thoughts on an Indiana Prenup
Indiana’s one-pot rule means that without an agreement, almost everything you own can end up on the table in a divorce. A prenup is the tool that lets you decide in advance what stays yours.
The keys to a valid agreement are honest disclosure, a written and signed document, and enough time before the wedding. Get those right and an Indiana court will usually hold both spouses to the deal they made.
