Purshis is a legal procedure to get verbal remarks of opposite party (OP) into the court records. I think the benefit can be that if OP has made some verbal remarks in court which can benefit your case later, then it is best to get them into court records. Several times someone driven by stupidity and emotion may make verbal remarks thinking that these are only verbal remarks not a document so there is no harm. However purshis may be useful in these cases. Follow links below for more information on purshis.

Format of Purshis

(from SIF Jul09):

On top simply write "Pursis in the matter of ............."
At the end write - Hence this Pursis.
This is usual practice, use it, then come to know.
