Føderåd or kår

I hope you can help me with the term føderåd. My ancestors settled in Wisconsin in 1850. The oldest son to immigrate entered into contracts to purchase 120 acres in 1853. In 1861 he sold the contract to buy the land to his brother, Elias for $300. Elias borrowed the $300 from his parents. I have found a contract between Elias and his parents stating the “condition of their (Elias, his heirs, executors, and administrators) obligation . . . for and in consideration of a competent sum to him (Elias) in hand paid by (the parents),” basically that Elias will maintain his parents with “meat, drink, clothes, and all other things, necessary and convenient. Would this be called in Norway a føderåd? I also have found the term kår and my dictionary says it is “a sort of pensioner, receiving support from new owners of the farm by contract made on the sale. Is this a contract a Kår or a Føderåd or neither?
