(b) Whenever any land so held by tenants in common shall be sold upon proceedings in partition or shall be taken by the election of any of the parties to such proceedings, or when any real estate shall be sold at judicial sale, or any administrator's, executor's, guardian's, or trustee's sale, the court shall order the taxes and penalties and the interest thereon, against the lands to be discharged out of the proceeds of the sale or election.
