To apply for gpoa from court only know the year it was made

Whether the executant (your grand parents) are alive, if so, it is valid otherwise, it has no legal value.  

Happy day,

I just remember a few lines as I have used it to transfer one of property of my grand father after his demise to my grand mothers name.

And even if not valied  I would want to apply for a copy of the same. Guide me regarding.

Thank you
