Given a set , is there a disjoint set with an arbitrary cardinality?

Dear all:

Given a set X and a cardinal k, is there a set Y such that card(Y)=k and
X is disjoint from Y?

Is there a proof of this fact that works without the axiom of regularity
(= axiom of foundation) and does not assume purity of sets?

Thanks in advance

Jaakov.
