Reed's executors value musical rights and various other assets in his estate at $20.3 million in court papers filed Monday in Manhattan.
The sum doesn't include the East Hampton, New York, home Reed bought for about $1.5 million in 2009 or his Manhattan apartment in a building where apartments sell for millions.
Reed's lawyer and one of his executors didn't immediately return calls Tuesday. The filing is part of the legal follow-up to Reed's will, filed in November.
The Velvet Underground frontman and "Walk on the Wild Side" singer died Oct. 27 of complications from a liver transplant. He was 71 and had no children.
