Prince's Estate Receives First Paternity Claim

— -- A man claiming to be the biological son of Prince has come forward.

Carlin Q. Williams filed paperwork in a Minnesota probate court today, in which he requested DNA testing.

His also petitioned to be determined as the late singer's "the sole surviving heir."

Prince died late last month at the age of 57, and afterward, his sister, Tyka Nelson, filed paperwork stating that she did not believe he had a will. As a result, Bremer Trust has been appointed to manage the music legend's estate.

Last Friday, a judge authorized Bremer Trust to have Prince's blood genetically analyzed should any possible heir present him or herself. In an affidavit filed today, Williams' mother, Marsha Henson, claimed that she met Prince in July of 1976 at a hotel in Kansas City, Missouri. Shortly thereafter, she claimed in the affidavit, they had sexual intercourse and conceived a son.

Nine months later, she gave birth to Carlin Q. Williams on April 8, 1977, she added.

Williams is currently serving time in federal prison in Colorado for weapons transport, according to federal court records obtained by ABC.
