Question on security deposit rules

[Paul Anderson]

Hi, my husband and I are new to this landlord thing and bought a property (duplex) and inherited some renters. They moved out and now are both saying different things about the original security deposit. The women claims she paid it all and wants it all back, the man claims he paid half to the women and he wants his half back.

We asked the previous owner of the property and she said the women paid in cash.

Since they co- signed the lease, our gut says to just split it down the middle and send them checks.

Is that what we are supposed to do?

Any legal issues with that?

Help! Thank you!!

Emily and Paul
