So, I purchased my first rental property around this time last year with my parents as part owners. It was in the middle of a 1 year lease with the tenants. In Canada we aren't allowed legally to take a deposit for potential damages, instead we take first and last months rent ahead of every lease . After a few phone calls between the previous owner and my mother it appears she is clearly avoiding to hand over last months rent. Apparently she at first said she didn't take last months rent from the tenants, then eventually went on to say she gave last months rent to her lawyer who we couldn't reach until this month who eventually said he hadn't received it. The tenants lease ended in April of 2018 and they said they paid the owner last months rent which was $1700. My mom is giving up on trying to go after it, but I feel its not right. Is it too late to go after her(previous owner) in court? Should I just forget about it? Im aware its our fault for not collecting last months rent when they handed over the property. What are my options here?
