Better deposit a crossed and dated cheque at nazer section of FC.
there are standard forms. fill it. get it ordered from the court. and deposit the cheque
mention all cheque number properly. Also check if separat execution petition is allotted or not.
It woon't be but cross check. also ensure you put correct case number of yours.
Any mistake will invite more hassles.
Before paying the cheque get photo copy of ordered sheet as well as cheque. and file it with you.
Depositing cash is also an option. but cumbresome for you.
Retain all receipts. Also if you are asked to pay cost as well then , deposit it as 'towards costs' accordingly
They create a separate register/ledger for your wife wherein she needs to give photo etc and id proofs and a witness during every withdrawl.
Ask wife about her bank a/c number and name of bank.
But I would suggest you not to give money or cheque directly to wife, unless court allows it so.
Otherwise one cna even do money transfer also, but wife may say it wasn't towards maintenance!! So again hassles....
You can also ask for nazer report as well over there for your records as well.
