Two scheduled events, due to be held at the late musician's Paisley Park estate in Minnesota, were reportedly axed following his death in April and party planner Ricky Barron says he was left out of pocket.
In a claim filed in Carver County, Minnesota and obtained by PEOPLE, Barron is asking for $56,260 "for work performed on behalf of Paisley Park [and] also for projected profits on events the estate cancelled".
One party was reportedly for the Make-a-Wish foundation, while the second was for Mixed Blood Theatre.
This comes after it was reported that Jack Reuler, the artistic director of Mixed Blood Theatre, is looking for $348,358 from the estate, following the cancellation of its 40th anniversary gala.
Meanwhile, Prince was found dead at his Paisley Park compound in April and it was recently revealed that a subsidiary of Graceland Holdings is to start running tours at the complex from October 6.
Fans will get the chance to look through the main floor of Paisley Park, including the recording studios where Prince recorded and produced some of his biggest hits.
Supporters will also be able to feast their eyes on some of the many awards the late star won, see his concert wardrobe, rare music and video recordings as well as several of his musical instruments.
Bremer Trust - the company overseeing Prince's affairs - announced the deal with Prince's sister Tyka Nelson.
She said in a statement: "Opening Paisley Park is something that Prince always wanted to do and was actively working on.
"Only a few hundred people have had the rare opportunity to tour the estate during his lifetime.
"Now fans from around the world will be able to experience Prince's world for the first time, as we open the doors to this incredible place.
"The new Paisley Park museum will offer fans a unique experience, an exhibition like no other, as Prince would have wanted it."
