Many tenants are like nomad. Is not easy to issue them legal documents.

You need to consider a few factors:
1. Is the tenant still refusing to shift out?
2. the possibility of recovery of the outstanding tnb bills even if you win the case and obtain a Judgement in your favour.
3. If you win the case, are Execution proceedings feasible? (Seizure and Sale, Garnishee, Judgement Debtor Summons, Committal, Bankruptcy)
4. What is your lawyer charging you? Does it exceed the outstanding utility bills?

There are some folks would rather be bankrupt than pay their debt.

Another issue is that, would the minimum debt threshold for bankruptcy be met?

The judge decides on what is pleaded in the Landlord's claim, which generally would be the full lump sum payment. It is not a choice on the part of the Tenant.

Debt incurred by the Landlord is immediately payable upon service of judgement on the Tenant.

Payment in installments would only be relevant if parties enter a consent judgement/execute a settlement agreement agreeing to a installment payment manner, where the quantum and date would be spelt out clearly.

Judge will decide to allow or dismiss the Landlord's claim.

If the landlord pleads for a lump sum payment, the judge can only decide to either:

1.allow in full  the Landlord's claim
2 allow in part, the Landlord's claim
3. dismiss the claim entirely.

Unless of course, for whatever reason, the Landlord pleads for an installment on his claim, then the judge may decide on that.

Debtors Act?

That is only applicable if the Landlord decides to file JDS proceedings.

This is the reply from TNB careline.

In the case that mini orchard presented, the amount might be to big to be ignored by TNB as the owner didn't bother to check the money owed on monthly basis. TNB apps already existed more than 3 years ago, that's how I check as it's ease me.

For smaller amount case, I believed the changing name and reconnection should be no issue.

Thank you for your deviation of subject and to put TS case in context to make it interesting, does the amount owed amounted as per your example or applicable to him as what I suggested?

Will not reply further. I already suggested solutions and provided info for clear clarification from TNB on the blacklisting and reconnection issue. Purpose of my reply is to help him. Not to nitpicking for the sake of it. I'm done here.
