Indiana Code Title 32. Property § 32-22-1-5

Sec. 5. (a) If a person owning real estate desires to sell the real estate or a part of the real estate and the person's spouse is, at the time, mentally incompetent, the person, upon complying with this section, may sell and convey the real estate by deed without the joinder of the mentally incompetent spouse.  The conveyance has the same effect as would the joint deed of both spouses.

(b) Before a deed is made under this section, the owner intending to sell the real estate shall, by petition, apply to the court having probate jurisdiction in the county where the real estate or a part of the real estate to be sold is situated, alleging that the owner's spouse is mentally incompetent and that the incompetency is probably permanent.  Upon the filing of the petition, notice shall be given to the person alleged to be mentally incompetent, either by service of process, as provided by law for service of process against incompetent persons in other civil actions, or, if the person alleged to be incompetent is by affidavit shown to be a nonresident of Indiana, by publication.

(c) After notice and upon or after the return day of the notice, the legally appointed guardian, if any, of the person alleged to be mentally incompetent or, if there is no guardian, a guardian ad litem for the person appointed by the court, shall make any proper defense to the application.  The matter of the petition shall be submitted to the court, and if the allegations are proved to the satisfaction of the court, the court shall make and enter a finding that the person alleged to be incompetent is incompetent, and that the incompetency is probably permanent.

(d) Upon the filing by the petitioner with the clerk of the court of a bond, in an amount and with surety approved by the court, that is payable to the state and conditioned to:

the court shall enter an order authorizing the whole title to be conveyed by the petitioner without the joinder of the mentally incompetent spouse.

(e) A deed made under an order of court under this section has the same effect as the deed of an unmarried person competent to convey real estate.

(f) If it is shown to the satisfaction of the court having probate jurisdiction in the county in which lands authorized to be sold under this section are located that:

the court shall enter an order discharging the bond described in subsection (d) and releasing the sureties from all liabilities on the bond.
