Ind. Code § 22-4-14-4
As a condition precedent to the payment of benefits to an individual with respect to any week such individual shall be required to serve a waiting period of one (1) week in which he has been totally, partially or part-totally unemployed and with respect to which he has received no benefits, but during which he was eligible for benefits in all other respects and was not otherwise ineligible for benefits under any provisions of this article. Such waiting period shall be a week in the individual's benefit period and during such week such individual shall be physically and mentally able to work and available for work. No individual in a benefit period may file for waiting period or benefit period rights with respect to any subsequent period. Provided, however, That no waiting period shall be required as a prerequisite for drawing extended benefits.
