If you've built a life with your partner in Indiana but never married, you may have a serious legal gap that most people don't discover until it's too late. When your partner passes away, Indiana law doesn't automatically give you any claim to their property even if you shared a home for decades. An Indiana affidavit of heirship for unmarried partners is one tool that can help establish your connection to property you may have a right to, but it comes with important limitations every unmarried partner should understand.

What Is an Affidavit of Heirship in Indiana?

An affidavit of heirship is a sworn legal document that identifies the rightful heirs of a deceased person's estate. In Indiana, this affidavit is typically signed by someone who has personal knowledge of the deceased's family history often a disinterested witness, not an heir themselves. Once filed with the county recorder's office, it creates a public record linking heirs to specific real property.

For unmarried partners, this document becomes especially important when the deceased partner owned real estate such as a home, land, or rental property that was held solely in their name. Without a will naming you as a beneficiary, Indiana's intestate succession laws (Indiana Code § 29-1-2-1) determine who inherits, and unmarried partners are not on that list.

Can an Unmarried Partner Inherit Property in Indiana?

Indiana's intestate succession law distributes property to surviving spouses, children, parents, and siblings in that order. An unmarried partner, no matter how long the relationship lasted, has no automatic inheritance rights under these laws.

That means if your partner dies without a will (intestate) and you weren't married, you cannot simply file an affidavit of heirship to claim their property. The affidavit reflects the legal heirs as defined by state law, and as an unmarried partner, you are not considered a legal heir.

However, there are situations where an affidavit of heirship still matters for unmarried partners:

  • Jointly owned property: If both names appear on the deed as joint tenants with right of survivorship, the surviving partner may already have a claim. An affidavit can help clarify ownership and clear the title.
  • Property passed by will: If the deceased had a valid will naming you as a beneficiary, the affidavit can support the transfer process alongside probate.
  • Adverse possession or equitable claims: In rare cases, unmarried partners may have contributed to mortgage payments, taxes, or property improvements. These situations may require additional legal steps beyond an affidavit.

When Would an Unmarried Partner Use an Affidavit of Heirship?

There are a few specific scenarios where this document becomes relevant:

You and your partner owned property together

If both names are on the deed, the surviving partner typically needs to document the death and remove the deceased's name from the title. A properly completed affidavit of heirship filed with the county recorder can help establish the chain of title and make it easier to sell, refinance, or manage the property.

You want to sell property that was in your partner's name

Title companies in Indiana often require an affidavit of heirship to issue title insurance when a deceased owner's estate was never probated. If your partner's legal heirs (such as their children or parents) are willing to transfer or sell the property to you, the affidavit helps document the heirship chain so the sale can move forward. You can find specific county recorder guidelines for unmarried partners that outline what's needed.

The estate is small and informal transfer is possible

Indiana allows simplified procedures for small estates. If the property's value is modest and the legal heirs cooperate, an affidavit of heirship may be enough to transfer real property without full probate.

What Does Indiana Law Actually Require for This Affidavit?

Under Indiana Code § 32-17-11, the affidavit of heirship must include:

  • The name and date of death of the deceased property owner
  • A description of the real property involved
  • The names and relationships of all known heirs
  • A statement that the deceased died without a will (if applicable)
  • The signature of a disinterested witness with personal knowledge of the family history

The witness cannot be someone who stands to benefit from the property transfer. For a full breakdown, review the Indiana affidavit of heirship requirements to make sure your document meets every standard before filing.

What Are the Biggest Mistakes Unmarried Partners Make?

Here are the errors that commonly cause problems:

  • Assuming common-law marriage applies. Indiana does not recognize common-law marriages created within the state. Even if you lived together for 30 years, the law treats you as unrelated individuals for inheritance purposes.
  • Filing without identifying all legal heirs. If your partner had children from a previous relationship, they are legal heirs. Leaving them out of the affidavit can invalidate the document and create legal disputes.
  • Using an affidavit when probate is required. If the estate has significant assets, debts, or disputes among family members, an affidavit of heirship alone won't be enough. Probate court may be necessary.
  • Not getting a disinterested witness. The witness must be someone who knew the deceased's family but does not stand to inherit. Using a close friend who is also named in the will won't work.
  • Failing to record the affidavit. The document has no legal effect until it's properly filed with the county recorder's office where the property is located. You can follow these county recorder steps to make sure the filing is done correctly.

How Can Unmarried Partners Protect Themselves Proactively?

The best time to plan is before anything happens. Here are practical steps unmarried partners in Indiana can take now:

  1. Create a will. A valid Indiana will is the most direct way to leave property to your unmarried partner. Without one, the state decides who inherits.
  2. Use joint ownership with right of survivorship. Titling property as "joint tenants with right of survivorship" means the property passes automatically to the surviving partner when one dies.
  3. Consider a transfer-on-death deed. Indiana allows TOD deeds for real property, which lets you name your partner as the beneficiary without going through probate.
  4. Put agreements in writing. If you and your partner share mortgage payments, property taxes, or home improvement costs, keep records. These records can support equitable claims if disputes arise later.
  5. Consult an Indiana estate planning attorney. Every situation is different. A local attorney can review your specific property and relationship circumstances and recommend the right combination of legal tools.

What Steps Should You Take Right Now?

If your unmarried partner has already passed away and you need to address property they owned, here's where to start:

  1. Confirm whether a will exists. Check with the county clerk's office or ask close family members.
  2. Identify all legal heirs under Indiana intestate law if there is no will.
  3. Determine whether the property was jointly owned or solely in the deceased's name.
  4. Find a disinterested witness who can attest to the family history and relationships.
  5. Prepare the affidavit of heirship using the correct format. Refer to a proper heirship affidavit form for Indiana property to avoid errors.
  6. File the completed affidavit with the county recorder's office in the county where the property is located.
  7. Consult an attorney if there are debts, disputes, or complex ownership issues involved.
