X died in 1984. There was no will and apparently no probate. The law firm that handled the matter states that all records were put into storage and subsequently destroyed. The County has no record of probate.
It has now come to light that X had not disposed of all of her real property during her lifetime as all interested parties had believed. Through oversight on the part of the family members, County Assessor's office, and the law firm, no one realized that a 10' by 300' strip of land had never been disposed of by X.
Here is how it happened:
X owned a parcel of land 250' by 300'. In 1959 she gave the western 125' x 300' portion to her daughter B, the deed was executed and notarized, but not recorded until 1982. In 1961 Decedent sold the eastern 115' x 300' portion to her son C, and the deed was recorded at that time. Since 1961, everyone believed and acted as though the 10' strip was a part of the western parcel, and so it is has been shown on the Assessor's map since the 1960's. However, the legal description of the western (nor the eastern) parcel includes the 10' strip. That is still in the estate of the decedent.
A grand-daughter now owns the western parcel, and has owned an occupied the 10' strip since 1986. How should the estate of the decendent be handled?
