In this paper, we show that there exists a knot which has infinitely many non-equivalent symmetric union presentations with the same partial knots. We also define an invariant of a symmetric union presentation and give alternative proofs to results of Eisermann and Lamm and a result of Collari and Lisca by using methods in 3-dimensional topology.
