Thank you! That was my plan B, and I am glad to know it is an acceptable approach. 

The other unusual, or perhaps not so unusual, piece of this situation is that there is a surviving spouse but she has dementia. My client has personal representative status for the widow, her mother. I'm in the process of clarifying if she has personal rep status for her father. But, regardless, wouldn't personal rep be adequate to file as if Mom was filing? 

Thank you for responding, 

Dawn
