Dear Client,

You need to take another certified copy of sale deed from the office registrar where you had registered the land.

You can take a certified copy of the said sale deed and produce in other bank if the bank is same then there is no issue. 

either you should obtain the original or a certified copy. if the shares are specified then bank will have no concerns.

there cannot be 2 originals when the joint names are in one property, the copy is sufficient. 

Hello,

there can be just one registered sale deed. The other person may obtain certified copy of the sale deed from the registry.

was sale deed in favor of a partnership firm?

regards

Partition deed must be executed in counter part. Well, get the certify copy of partition deed from sub registrar office.

1. There can be only one sale deed for a property. 

2. The second partner can obtain a certified copy of the sale deed from the office of sub-registrar and apply for loan on the basis of it. 

Since there's only one sale deed which has already been mortgaged there's no possibility for mortgaging the same once again without redemption or discharge of earlier loan.

In fact the first partner could not have mortgaged the property without the consent of other joint owner.

So better clarify the actual facts if you are really interested in getting proper legal opinion and advice.
