Recently I bought a condo unit that has an eight-month tenancy period and the tenant now wants to exercise his right to extend for another four months (which is allowed per the tenancy agreement).

The tenancy I inherited from the previous owner has all the following anomalies:

1. Tenancy agreement is stated between the previous owner (the husband) and the Tenant, but my previous owner's wife (she also owns the property) signed it. Does this make the agreement valid?

2. A handwritten note was made by the Tenant to extend his tenancy to run on a monthly basis. I take this as invalid change to a contractual document, which neither party countersigned. There is, however, the standard signature on every page. Must I observe this condition?

Breach of Contract

3. The standard 'extension' will only be granted provided there is no breach of the conditions of the tenancy agreement. We asked for the Tenant to produce his service records for the air-conditioning system which he must contractually service every 3 months, but he failed to do so. I am very concerned that he may now have the time to forge the service records to prevent this breach. What can I do?

4. We have witnesses that the Tenant had other people stay in the unit without seeking approval from the previous owner. This is cause for breach of contract. What is the process for proving this?

5. If points 3 and 4 can be proven, he has effectively breached the tenancy. Is the tenancy terminated? What steps should I take to get him out of my premises and how long would this take?
