TS, better tell your tenant, since so much bad blood, they have to vacate. Let the tenancy agreement lapse, after that tell them to move out.
If not, talk to a lawyer to help draft a lawyer letter to chase them out.
I will let you know, our tenancy laws actually side the tenant. Watch a movie called Pacific Heights starred by Michael Keaton, that is a nightmare tenant. Our laws virtually follow the USA law last time. Once you hand over the keys to the tenant, you gave them tenant possession, they are masters of the property. You want to do eviction? If you are rich, be my guess. Can cost a lot.
Maybe some posters say talk to them nicely, they may be right.
our parliament too busy fighting RnR issues, so they don't bother to make good laws or even to overhaul this obsolete tenancy laws.
The MO is not your friend. And by law they cannot cut the utilities of your tenant.
But based on the fact the tenant just maki hamun at you and your mum, for cutting the utilities, I suspect their knowledge in causing trouble isn't that extensive.
Because you actually broke the law, you can't block access to them, they have vacant possession.
Maybe you can exploit this loophole. Talk to them nicely, that relationships have broken down, you prefer them to move out, give them like 2 months. Else you will get your lawyer, just write the letter to scare them. See what they say?
But deep down, you are actually in the losing side, because if they want to cari pasal with you, they just wait....because eviction notice can cost you maybe up to 6k. And if you cut electricity, they can sue you.
The TA comes under the Contract Act .... i.e. the terms in the TA are negotiated and agreed between the landlord and tenant,
There is also no subsale SnP Act. So one cannot say the SnP sides the buyer. So if there is a breached, one can only blame the lawyer. ðŸ¤
If either party breached the contract, there are provisions in the TA for the aggrieved party to take action within the confine of the law.
Even when the TA is passed by parliament eventually, the rights of tenant and landlord are about the same today ... i.e. get an eviction court order. Maybe disconnecting utilities then may be an offense under the TA Act.
I foresee not much protections for landlord under the new TA Act, except maybe with quicker application for eviction order and lower cost, with landlord diy.
