Ms Ponsati had been in Belgium ever since fleeing Spain along with Catalan former president Carles Puigdemont and three other ex-Cabinet members following an unsuccessful bid to declare independence from Spain in October.
She and the others face arrest if they return to Spain.
An international arrest warrant had been issued for all five, but a Spanish judge later withdrew it.
