LL requiring a release of liability b4 refunding security???

[livingstonlivingtenant]

I've been renting in NYC now for nearly 10 years and this is the first time a LL has ever required that I sign a release of liability statement before having my security deposit refunded. The management company is Livingston Living and the main reason I moved out is that they are really awful at maintaining the building and responding to any problems. I've had cockroach infestations and my ceiling cave in and both problems took over 3 months for them to address. Now they're going to hold my security deposit hostage unless I release them from all liability? The original lease of course made no mention of this requirement. This isn't legal is it? I'd really like (read "need) to get my deposit back without taking them to court. Any advice?
