There should be clause in sale deed that development charges would be paid by buyer only 

2)you are  not liable to pay after execution of sale deed 

3) mere letter is not sufficient 

In sale deed condition that any development charges prior to sale or after same has to be paid by the current buyer and seller has no responsibility of the same. 

1. See it is better to add in sale deed.

2. Yes.

3. Yes you can separately also ask for such letter. Further once you sale they will ask from new buyer.

Sir,

     After sell, all dues, expenses is transferred to buyer itself.

     So in your case development charges should be paid by buyer itself.

     Only thing you can do, clearly mentioned in your sale deed.

     mere letter is not sufficient means.

      yes you can.

      You can take for your safety, no problem in this.

To protect your interest there should be clause in sale deed that seller is not responsible for payment of development charges 

2) in event any liability arises of payment of development charges shall be borne by buyer only 

3) no need of any letter from buyer 

1. Once you sell the property then all your rights and liabilities over it gets relinquished and the same is developed upon the buyer unless there is stipulations on the contrary.

2. In other words if in the sale deed you do not take the liability of past, present or future development charges then the buyer alone is responsible for it and hence there is no requirement for any letter on this.

3. However to be on te safer side on this account you may specifically mention the clause absolving your liability to pay such charges in the deed of conveyance itself.

The development charges are levied when there is an express term in the agreement. If you had these terms and conditions in the agreement when you bought the land then the person buying it from you should also pay as and when there is development.

In the agreement you should specifically mention this aspect and then go ahead.

Regards 

Mention in the sale deed, if any development charges due or payable shall be borne by buyer. Generally, before sale charges if any due borne by seller but if buyer agree in sale deed if will be responsible than you will  exonerate.

It is paid by developer if the seller is the developer then he has to bear it. If buyer agrees to pay the same it's beneficial to seller. But ideally it is paid by developer

1.  "IF" at all any legitimate development charges are payable, THEN it shall be payable by the actual owner of the property as on date of demand.

2.  The Sale Deed should have a specific clause that development charges shall be payable by the new owner.  This clause would absolve you from this liability and the new owner becomes bound by this liability.

Dear sir,

Developers have to pay 'external development charges', or EDC, to the government for civic amenities such as roads, water/electricity supply, sewerage and drainage. The EDC is fixed by the local authorities and is passed on to buyers in proportion to the built-up area of their properties.

Dear

You have to make an agreement regarding payment of development charges by buyer of the plot. 

The buyer who is buying the plot is liable to pay development charges.

Yes you need to get the agreement registered or you can add clause regarding development charges in the sales deed. 

If the dues are pending against the original buyer then he have to pay, however if the property has been bought by the new buyer then he will pay it and recover it from his seller.

The buyer is not obliged to give any such letter, the seller cannot shed away his liability in this manner.

No such recital in the sale deed is maintainable in law.

The buyer may pay the old dues but he cannot be held liable for the arrears hence he may sue you i.e., the seller for recovery of the amount paid by him.

As a matter of fact if the claim is beyond three years from the date of claim, it may not be maintainable owing to the limitation laws.
