What is Registered Post AD?

Sometimes law requires us to send “Registered Post A. D.” under a various provision in legal matters, This “Registered Post A. D.” means Registered Post with Acknowledgement Due or Register Acknowledgement. You may often see this on the top of legal letters.

Now the question arises “what is Registered Post with Acknowledgement Due (RPAD)?”

In general postal service, we send a letter to reach a certain destination and we believe that would land to its purposeful receiver, however, that might not be case always but in certain legal issues we can not just take that type of risk where there is a risk of ending up on the wrong hand, therefore a check system is maintained by getting an “Acknowledgement” from the receiver by a piece of paper with his sign (or who receives on behalf of him) that confirms the document is properly served, which is very important in complex legal issues and can be used as evidence in the court. That signed document (of receipt) is then delivered backed to the sender and the post office kept all the record (Registered). that’s why the evidential value of “Registered Post A. D.” too high and that much important.

How to send a Registered Post with Acknowledgement Due (AD)?

First, you have to write down the name of the sender and receiver unlike any other letter [ in the left side write down the name and full address of the sender and on top of it write “From” ; similarly, on the other side write down the name and full address of the receiver and on top of it write “TO” (Image given below)]

Then, you have to go to the nearest post office tell them that you want to send a letter/notice with AD They will provide you with a slip like paper on one side of it write down the sender’s name and address or where the sender wants to receive the receipt copy of the acknowledgement. Then attach that slip with the envelope on the opposite side where you put sender’s and receiver’s address.

Why do we use Registered Post?

Registered Postal Article details are  Registered into a special register, which ensures proper delivery of the article. On the other hand, an ordinary post which is dropped in the post box or at the counter of the post office is not registered and there is no proof of delivery available for it.

Can’t we just use private carrier service?

The answer is NO because the government doesn’t think so and no act is permitted to handle these legal issues under any private organization.

Legal Benefit of Registered Post

Under section 27 of General Clauses Act 1897 it said, if any person under any act serve any document by registered post where the proper procedure and processes are maintained, the post shall be deemed to be served on due time.

Meaning of service by post
27. Where any 1[ Act of Parliament] or Regulation made after the commencement of this Act authorizes or requires any document to be served by post, whether the expression “serve” or either of the expressions “give” or “send” or any other expression is used, then, unless a different intention appears, the service shall be deemed to be effected by properly addressing, pre-paying and posting by registered post, a letter containing the document, and, unless the contrary is proved, to have been effected at the time at which the letter would be delivered in the ordinary course of post.

Section 144 of Evidence Act 1872, along with  its illustration (f) shows that The court may think common course of business happened where a document is sent by registered post

Court may presume existence of certain facts

114. The court may presume the existence of any fact which it thinks likely to have happened, regard being had to the common course of natural events, human conduct and public and private business, in their relation to the facts of the particular case.


The Court may presume –

(f) that the common course of business has been followed in particular cases;

In both cases, there are may presumption of law, unless there are proved contrary these provisions are strong support as a legal ground.

Can we send a Registered Letter or Parcel without attaching an acknowledgement?

Yes. If the Letter or Parcel does not bear the words “Acknowledgement Due” or “AD” or indicate that an acknowledgement is required, the letter will be registered but no acknowledgement card will be sent to the sender. Mere registration that it has been delivered will be made in the postal register. Thereafter the sender can pay an additional fee and get a certificate of delivery from the postmaster.
