I hope you are well. My mother passed away just over a month ago. My stepfather, her husband, would like to reserve his place next to her and install his tombstone (mandatory where we live in Canada). He would like to know if, from a religious perspective, it is acceptable for him to install his tombstone already, considering he is in good health, thanks to God. Your opinion would be of great help. Thank you very much, and may God bless you.
