A Texas man who insists he's the brother of late actor Sherman Hemsley has been ordered to take a Dna test before challenging the validity of his will.

Richard Thornton alleges he is The Jeffersons star's sibling and should be entitled to cash in on his approximately $50,000 (£31,250) inheritance, which was left to the actor's longtime manager, Flora Enchinton, following his death this summer (12).

And on Monday (24Sep12) Judge Patricia Chew instructed Thornton to prove his family connection and turn over the laboratory results by 15 October (12) before the case can proceed.

A new court date has been set for 31 October (12).

Hemsley lost his battle with lung cancer on 24 July (12), aged 74.
