Indiana Code Title 32. Property § 32-17-14-15

Sec. 15. (a) Before the death of the owner, a beneficiary has no rights in the property because of the beneficiary designation.  The signature or agreement of the beneficiary is not required for any transaction relating to property transferred under this chapter.  If a lienholder takes action to enforce a lien, by foreclosure or otherwise through a court proceeding, it is not necessary to join the beneficiary as a party defendant in the action unless the beneficiary has another interest in the real property that has vested.

(b) On the death of one (1) of two (2) or more joint owners, property with respect to which a beneficiary designation has been made belongs to the surviving joint owner or owners.  If at least two (2) joint owners survive, the right of survivorship continues as between the surviving owners.

(c) On the death of a tenant by the entireties, property with respect to which a beneficiary designation has been made belongs to the surviving tenant.

(d) On the death of the owner, property with respect to which a beneficiary designation has been made passes by operation of law to the beneficiary.

(e) If two (2) or more beneficiaries survive, there is no right of survivorship among the beneficiaries when the death of a beneficiary occurs after the death of the owner unless the beneficiary designation expressly provides for survivorship among the beneficiaries.  Except as expressly provided otherwise, the surviving beneficiaries hold their separate interest in the property as tenants in common.  The share of any beneficiary who dies after the owner dies belongs to the deceased beneficiary's estate.

(f) If no beneficiary survives the owner, the property belongs to the estate of the owner unless the beneficiary designation directs the transfer to a substitute beneficiary in the manner required by section 22 of this chapter.
