The I Will Always Love You star's accolade is set to hit the auction block on Friday (24Jun16), but executives at The Television Academy are reportedly planning to head to court on Wednesday (22Jun16) to block the sale.

According to TMZ.com, Emmy winners sign agreements stating their heirs must "return the statuette to the Academy" following the death of the recipient, but a representative for the auction house reveals he has asked academy bosses to produce the agreement - and they haven't.

The Emmy is expected to sell for upwards of $10,000 (GBP6,800).

Houston won the award in 1986 for her performance at the 28th Annual Grammy Awards
