Return security deposit

[Adam Rhodes]

I’ll try to keep it short. I’m subletting a townhouse on Oahu. I have 2 cotenants. For the sake of the post I’ll call them jack and jerry. The lease was for 6 months . I received security deposit and every months rent from Jack for 6 months and then allowed a one month continuation of lease. From Feb 2021 to end of August 2021. Jerry moved out against jacks wishes sometime in June and left Jack with the entire rent amount until end of August. Jerry is now asking me for half security deposit after lease term expires. The question is, how do I divide security deposit if I do so at all? There’s no specific Hawaii law stating how to do so other than return within 14 days. Ive read I could be held liable for co conspiring to withhold money from other tenant if I don’t write one check made out to both of them. Again, both signed the lease but I’ve been receiving all payments from Jacks account however Jerry claims he paid half deposit to Jack. Thanks in advance and sorry for the long post!!
