Hello.
The question text is short, and there are quite unclear points about the situation, so it's difficult to answer, but I'll write it for reference only while making up for it with imagination.
My deceased uncle's “family temple” is also my uncle's “temple with a grave.” However, the funeral was held “far away,” and the funeral was probably performed by the “monk who performed the funeral” introduced by the funeral director.
However, after the funeral, the “monk who performed the funeral” “told me to get a kakana from the temple where the tomb is located.” On the other hand, it is said that “at the family temple of my uncle's parents' house, I can't use a kajime.”
First, didn't they contact the “family temple at my parents' house” at the time of the funeral?
Recently, there have often been cases where funerals are held without contacting the “family temple,” judging by oneself because it is “far away,” and cases that have become a problem have also been asked recently.
If you first contact the “family temple” and the “family temple” is “far away” or “COVID-19,” it makes sense (there are temples where you can go even “far away”), but from the beginning, you didn't ask the “monk who performed the funeral” introduced by the funeral director because it was “far away” at your own discretion?
“Bodaiji,” which is a “temple with graves,” manages funerals and graves from generation to generation, and if there is an awareness that they are parishioners, there is a possibility that they decided that it makes no sense to complete the funeral without contact and just an ossuary.
If the situation is as described above, how about admitting the fault of not contacting the “family temple” at the time of the funeral, even if unwillingly, and then making a request again?
Apart from whether or not it is OK for the “family temple” side to even say “it is not possible to give a kaku name,” I think it is necessary to consider the method if it is not possible to give the kyo name or accept the bones without asking about the intentions of the temple that manages the tomb.
As I declined at the beginning, I've pretty much made up for the facts with imagination.
Please read it on that premise.
