Wedding Cater and refund

I would re-read your contract or ask them to explicitly tell you where in your contract it said it was non-refundable. Usually deposits aren't refundable, especially when the reason is that you found another caterer.

I don't think so, since it isn't stated anywhere they will return it. Usually a deposit is so you don't cancel on them, like an insurance policy for them.

I would say since there is nothing in your contract that states the deposit may be refunded, then you shouldn't expect to get it back.

Deposits are an insurance policy for both you and the caterer. Without there being some extenuating circumstance (you had to cancel the wedding, had an accident, etc) there is no reason that the caterer should consider giving you the deposit back. They keep that is compensation for the potential money they lost by holding that date for you and not letting someone else get it. Unfortunately I think you may just lose that money.
