I am in the process of obtaining a copy of a 1974 will in BC. My understanding is that when there was a will AND when there was enough of an estate that the will had to go to probate, that only then will there be a record of the will and what happened to the estate. After some years the court records get sent to the Royal British Columbia Museum & Archives. I do not know how long the courts hold them before doing that but apparently it is a number of years and may vary from court to court. In the case that I am working on, the name does not appear in that index list in Family Search but when I asked at the Archives someone looked up the name somewhere and said that there was a record of an estate for that person in the time period I described. The archivist then had the file retrieved from storage and a couple of days later called me. Having the file in hand, she was able to confirm the death date, which I already knew, so that we were sure it was the right person. I then had the choice of having a copy mailed to me or sent to me electronically. There was a charge. It varies according to the size of the file but mine was about $33. I expect a copy of the will to arrive in the mail on September 4th!
