M: Hello.
W: Hello, Frank. This is Susan. I’m sorry to phone you at this hour, but I’m experiencing a sticky issue that I can’t think of anyone to get advice beside you.
M: What’s up?
W: Well, I moved to my present apartment couple months ago and now I plan to return to my parents’ place next month. Today, I gave notice to my landlord but he said he’s unable to give my deposit back since I have to stay a minimum of six months.
M: Are you giving him a-month-in-advance notice to move?
W: Yes, that’s exactly what I did today. In the tenancy agreement that’s the timeframe requested to notify the landlord.
M: Yes, that’s the usual practice.
Well, in the tenancy agreement, did it state that there’s a minimum of six months stay or the deposit would be forfeited?
W: Not that I could remember. Besides, I have never heard of such clause in the contract.
M: Well, perhaps you should pull your contract out and have a word with the landlord.
W: Yes, that’s exactly what I’m thinking of. But he said he spent time and money on advertisements to get tenant and it wouldn’t be fair on him if I just stayed for two months.
M: Well, that’s not the point, Susan, the fact is he shouldn’t force a tenant to stay. Besides, if the contract does not state the time frame, then he shouldn’t impose it on himself.
W: You are right, Frank. You just confirmed my reasoning.
M: Look, Susan, I’ll go with you to see the landlord tomorrow and if he still insists on forfeiting your deposit, we’ll go to the small claims court to get your money back.
W: Thanks, Frank.
