The following are some of the types of assets that the Estate Recovery Program can seek to recover:
Real property, including property conveyed to the recipient’s survivor through joint tenancy with right of survivorship.
Money remaining in the recipient’s bank account regardless if the account has a payable on death provision or has a joint owner.Money remaining in a recipient’s nursing home account.
Funds remaining in a Qualified Income Trust, also known as a Miller Trust, as of the date of death.
Funds remaining in a funeral trust after the funeral has been paid for in full.
Annuities purchased after May 1, 2005, including annuities that do not designate the State of Indiana as the beneficiary.
Assets in a revocable trust if the assets were transferred into the trust after May 1, 2002.
