He moved to the Alabama Territory in 1818, settling in Claiborne, and continued the practice of law.

In 1819, he was elected to the first Alabama House of Representatives under state government.

In the 1830s, he partnered with Lyman Gibbons, who married Dellet's daughter Emma, and who went on to serve on the Alabama Supreme Court.

He was interred in a private cemetery on his Dellet Park plantation at Claiborne.
