My sister's daughter is getting married soon. Sister is widowed and dating a guy (for several months). Sister wants Date to sit with her in the first pew (Sister will be walked down the aisle to sit in first pew). Daughter says it is her wedding and she does not want date to sit in the first pew (where her late father would have been). Mother is paying for the reception.
Where does etiquette fall and where should Date sit?
