Veteran Congress leader and former chief minister N.D. Tiwari married Ujjwala Sharma here on Thursday morning.
Sharma was the woman whose son Tiwari recently accepted as his own after a lengthy lawsuit.
Rohit Shekhar, 32, had taken the politician to court after Tiwari had refused to acknowledge their biological relationship.
In March, Tiwari publicly accepted Shekhar is his son.
In 2012, the Congressman, who had resisted submitting blood samples for a DNA test, was ordered to cooperate by the Supreme Court
The Delhi High Court then ruled that DNA tests proved that Tiwari had fathered Shekhar.
Shekhar was reportedly among the guests present at the wedding.
