My wife's affidivit is signed by her advocate

No it is not valid...

I don't think  that the advocate has made signature of his client.. collect correct information... 

Advocate must have file restoration application by filing his own affidavit... as matter DID because of his fault....

The person making an affidavit (the deponent) must sign the bottom of each page in the presence of an authorised person, such as a lawyer or Justice of the Peace. On the last page of the affidavit the following details must be set out (known as a jurat):

• the full name of the person making the affidavit, and their signature
• whether the affidavit is sworn or affirmed
• the day and place the person signs the affidavit, and
• the full name and occupation of the authorised person, and their signature.

If any alterations (such as corrections, cross-outs or additions) are made to the affidavit, the person making the affidavit and the witness must initial each alteration.

collect correct information whether that affidavit is her r advocate affidavit. if her affidavit is giver no its is not valid. in her affidavit she only sign her signature

It is not valid and illegal amounting to forgery.   This can be brought out at the time cross examining her on the basis of the evidence let in through her affidavit.
