1) you have not furnished any details of the criminal case filed by tenant against your brother and son

2) in the absence of details it is difficult to advise

Under what provisions of law is the FIR lodged? You should engage a defence lawyer to firstly obtain bail and thereafter contest the case on merits.

1. What are the charges leveled against him?

2. If he has filed a criminal case directly without lodging any police complaint finally registered by police as a FIR, then there will be no arrest and your brother won't have to avail anticipatory bail,

3. Engage a local lawyer having expertise in contesting criminal cases and contest the case fittingly.

Hi

Not sure on the nature of the criminal case.

if it is a case of trespass then you can always say that you had authorised your brother and his son to enter in to the property and look after the affairs of the property on your behalf.

What was the reason and what are the sections by which your tenant has lodged a criminal complaint.

However your brother and his son can obtain anticipatory bail and challenge the case before the trial court.
