A family is facing a dispute over a father-in-law's will. The husband's sister claims there is no will and demands a share of the property, accusing the husband of attempting to sell it using forged documents. The family disputes these claims, stating a will was signed in 1995 and that they cared for the father during his illness. The sister is now demanding a significant sum, and the family is seeking advice on how to respond to the legal notice and whether to pursue probate.
