An annulment in Indiana is a court declaration that a marriage was never legally valid, and it is available only on narrow grounds: the marriage was void from the moment it occurred, or it is voidable because of underage marriage without juvenile court approval, mental incompetence at the ceremony, or serious fraud. Unlike divorce, which ends a valid marriage, annulment treats the marriage as if it never happened. The person filing carries the burden of proof, and the ground has to have existed at the time of the wedding itself.
Who Qualifies: Void and Voidable Marriages
Indiana splits invalid marriages into two categories, and which one applies to you decides both the grounds you can raise and how the court handles the case.
Void Marriages
A void marriage is one the state refuses to recognize from the start. The grounds are:
- Bigamy, where one spouse was already married to someone else at the time of the ceremony.1Justia. Indiana Code Title 31 Article 11 Chapter 8 – Void Marriages
- Marriages between people more closely related than second cousins.1Justia. Indiana Code Title 31 Article 11 Chapter 8 – Void Marriages
- Marriages where either spouse was mentally incompetent at the time of the ceremony.2Indiana General Assembly. Indiana Code 31-11-8-4 – Mentally Incompetent Persons
- Common law marriages entered into after January 1, 1958.3Indiana General Assembly. Indiana Code 31-11-8-5 – Common Law Marriages Entered Into After January 1, 1958
- Marriages where Indiana residents traveled to another state specifically to marry in a way Indiana prohibits, then returned to live in Indiana.4Indiana General Assembly. Indiana Code 31-11-8-6
Bigamy, close-relative marriages, and post-1958 common law arrangements are void without any court proceeding at all. Even so, getting a court order is almost always the right move. It creates a clear public record and heads off later disputes about property, benefits, and paternity.
Voidable Marriages
A voidable marriage is treated as valid until a court annuls it. Indiana recognizes two grounds.
The first is incapacity. Both parties must be at least 18 to marry in Indiana. A 16- or 17-year-old can marry only if a juvenile court grants approval and fully emancipates the minor; parental consent alone is not enough.5Indiana Judicial Branch. Apply for a Marriage License A minor who married without that court order can petition for annulment.6Justia. Indiana Code Title 31 Article 11 Chapter 10 – Actions to Annul Voidable Marriages
The second is fraud. If one spouse tricked the other into marrying through a significant misrepresentation, such as hiding a serious criminal history, lying about the ability to have children, or concealing an existing marriage-like relationship, the deceived spouse can seek an annulment. The misrepresentation has to go to the core of the marriage. Minor exaggerations do not qualify.
Only the affected spouse can file to annul a voidable marriage. A parent, sibling, or in-law cannot bring the petition on their own.
Residency and Where to File
At least one spouse must have lived in Indiana for six months immediately before filing, and at least one spouse must have lived in the filing county for three months.7Indiana General Assembly. Indiana Code 31-15-2-6 Military members stationed at an Indiana installation satisfy the residency requirement even if their official home of record is elsewhere.
You file the petition in the circuit or superior court of the county where the residency requirement is met. The petition has to name the specific statutory ground and lay out the facts supporting it. A vague filing will not survive.
Filing Fees, Service, and the Hearing
The base filing fee for a civil case in Indiana is $157.8Indiana State Board of Accounts. 2025 Court Costs and Fees by Case Type Some counties classify annulments as domestic relations cases, which add a $20 alternative dispute resolution fee for a total of $177. Sheriff’s service usually runs about $28 more. Call the county clerk before filing to confirm the classification and the total.
Your spouse must then be formally served. Indiana permits personal delivery by a process server or sheriff’s deputy, certified mail with return receipt requested, or leaving a copy at the home followed by a first-class mailing.9Indiana Courts. Indiana Rules of Trial Procedure Rule 4.1 – Summons: Service on Individuals After service, your spouse has 20 days to file a response, with an automatic 30-day extension available by notice.
At the hearing, you have to prove the ground existed at the time of the ceremony. For fraud, that means showing the lie was serious enough to go to the heart of the decision to marry. For mental incompetence, expect to need medical records or expert testimony tied to the wedding date. Judges do not treat annulment as a faster or easier alternative to divorce, and thin evidence loses.
Defenses the Other Spouse Can Raise
The most effective defense in a fraud case is continued cohabitation. If the petitioner learned about the fraud and kept living with the other spouse, Indiana law treats that as ratification and denies the annulment.6Justia. Indiana Code Title 31 Article 11 Chapter 10 – Actions to Annul Voidable Marriages Many fraud petitions fail on this point alone. The respondent can also argue the misrepresentation never happened, was not material to the decision to marry, or was actually known to the petitioner before the wedding.
For incapacity claims, the respondent might present evidence that the petitioner was fully competent at the ceremony, or that a minor petitioner did in fact secure juvenile court approval. Contemporaneous medical records carry significant weight.
Facts that developed after the wedding will not support an annulment. Those situations call for divorce.
Property Division After Annulment
Because an annulment legally erases the marriage, the equitable distribution rules that govern divorce do not apply the same way. Courts generally try to return each person to the financial position they held before the marriage. That means returning property to whoever originally owned it and accounting for financial contributions each person made during the relationship.
In practice this gets messy fast. A jointly bought house, merged bank accounts, or shared debt cannot be unwound cleanly. Indiana courts have wide discretion here, and outcomes are less predictable than in divorce. If significant assets are on the table, legal representation can materially change the result.
Children Born During the Marriage
Annulment does not affect the legal status of children. Indiana presumes that a man is the father of a child born during a marriage, even one later annulled, and the same presumption reaches children born within 300 days after the annulment.10Justia. Indiana Code Title 31 Article 14 Chapter 7 – Presumption of Paternity
Custody follows the same best-interests-of-the-child framework used in divorce, weighing each parent’s relationship with the child, the child’s adjustment to home, school, and community, and the mental and physical health of everyone involved.11Indiana General Assembly. Indiana Code 31-17-2-8 – Custody Order Neither parent is presumed to be the better custodian.
Child support is calculated under the Indiana Child Support Guidelines regardless of how the marriage ended, based on each parent’s income and parenting time.12Indiana Courts. Indiana Child Support Rules and Guidelines
Collateral Consequences: Benefits, Insurance, and Immigration
Annulment can reach into areas people rarely think about until they are already in the process.
Social Security
If you were receiving Social Security benefits that stopped when you married, such as benefits on an ex-spouse’s record or certain survivor benefits, an annulment can restore them. The Social Security Administration treats an annulled marriage as though it never happened, so benefits can restart as of the month the decree was issued. You have to file a timely application; SSA will not reinstate benefits on its own.13Social Security Administration. Social Security Handbook – Section 1853
Health Insurance
If you were covered under your spouse’s employer plan, that coverage ends with the annulment. Federal law makes divorce and legal separation qualifying events for COBRA continuation coverage, which allows up to 36 months on the plan at the full premium. The COBRA statute names divorce and legal separation rather than annulment, but most plan administrators and the Department of Labor treat annulment as triggering the same rights. Contact the plan administrator right away. The COBRA election window is 60 days.
Immigration
For someone who obtained a green card through the marriage, an annulment creates a serious problem. Conditional permanent residents have to show that the marriage has not been terminated in order to remove the conditions on their residence. An annulment makes that showing impossible, and USCIS can deny the petition, which leads to removal proceedings.14USCIS. Conditional Permanent Resident Spouses and Naturalization If you hold a conditional green card and your spouse is filing, talk to an immigration attorney before the annulment is finalized. The timeline for waivers and alternative relief is short.
