Is faxed document a valid proof in matrimonail case

it is a secondary evidence as per the indian evidence act, 1872

I was reading indian evidence act  and it reads

Secondary evidence may be given of the existence, condition or contents of a document in the following cases:

(a) When the original is shown or appears to be in the possession or power of the person against whom the document is sought to be proved, or of any person out of reach of, or not subject to, the process of the Court, or of any person legally bound to produce it, and when, after the notice mentioned in Section 66, such person does not produce it;.

In my case when the document is in posseion of US institution which is not subjected to court proceedings of India, Will my fax admitted as evidence?

when the secondary evidence marked subject to objection, the burden of proof upon such person who produced the secondary evidece. hence if your documents will recieved subject to objection it is necessary to give oral evidnce for proving the secondary evidnce
