Reclaiming Alimony After Recalculation

Questioner

I've been divorced from my ex-husband for two years. I always paid him €255 a month in child support. He receives welfare benefits, and the alimony payments are being reduced. I had my alimony recalculated after I had to cut back on work to care for my sick son. As of September 1st, after the recalculation and his approval of his benefits, I've stopped paying alimony, and he'll receive the full amount. However, I pay his alimony in advance and have already paid for September and October. Does he have to repay it to me?

Questioner

Yes, afterwards you paid that amount without being obliged to do so, and the legal basis no longer existed.
