If there is no clause in the agreement about deduction of deposit in lieu of notice period, it will be illegal to deduct the amount from the security deposit.
You may withhold a certain portion of amount from the deposit in the name of expenses for repairs and painting works and can settle the balance amount stating that the balance from the withheld amount shall be refunded after the expenses are met, if any.
Also i have given lcd tv for their use.it is in working condition when i given them.during this tenure the tv got problem and they repaired the tv.now they are asking me to pay the amount to me for repair.kindly advice
You do not have to pay anything for this because the television was handed over in a good condition to them, if they did not maintain it properly it was their responsibility to bear the repair expenses moreover it was they who utilised the services of the TV after getting it repaired, so their claim can be repudiated.
In the same agreement there is a clause that they should pay the electric and water bill.they are paying electric bill but they have not paid water bill.can i deduct water bill from their depisit.thanks
You can very well deduct all the outstanding dues to be received from them including the yet to be received electricity bills proportionately.
